Storage comparison: Dell PowerMax 8500 vs. Pure Storage FlashArray//XL170Principled Technologies
A Principled Technologies research report based on publicly available information
One of the ways vendors support buyers of their offerings is by providing public information about their products. We found that Dell offered easy-to-find vital data about the PowerMax 8500 array to assist organizations making a storage decision. In contrast, Pure Storage offered comparatively little public information about the PureArray//XL170 as of this writing. The publicly available information we found suggests that the Dell PowerMax 8500 array surpasses the Pure Storage PureArray//XL170 in the categories we researched, with greater expandability and capacity, higher throughput and lower latency, mainframe support, and verified suitability for secure environments.
What CloudStackers Need To Know About LINSTOR/DRBDShapeBlue
Philipp explains the best performing Open Source software-defined storage software available to Apache CloudStack today. It consists of two well-concerted components. LINSTOR and DRBD. Each of them also has its independent use cases, where it is deployed alone. In this presentation, the combination of these two is examined. They form the control plane and the data plane of the SDS. We will touch on: Performance, scalability, hyper-convergence (data-locality for high IO performance), resiliency through data replication (synchronous within a site, 2-way, 3-way, or more), snapshots, backup (to S3), encryption at rest, deduplication, compression, placement policies (regarding failure domains), management CLI and webGUI, monitoring interface, self-healing (restoring redundancy after device/node failure), the federation of multiple sites (async mirroring and repeatedly snapshot difference shipping), QoS control (noisy neighbors limitation) and of course: complete integration with CloudStack for KVM guests. It is Open Source software following the Unix philosophy. Each component solves one task, made for maximal re-usability. The solution leverages the Linux kernel, LVM and/or ZFS, and many Open Source software libraries. Building on these giant Open Source foundations, not only saves LINBIT from re-inventing the wheels, it also empowers your day 2 operation teams since they are already familiar with these technologies.
Philipp Reisner is one of the founders and CEO of LINBIT in Vienna/Austria. He holds a Dipl.-Ing. (comparable to MSc) degree in computer science from Technical University in Vienna. His professional career has been dominated by developing DRBD, a storage replication software for Linux. While in the early years (2001) this was writing kernel code, today he leads a company of 30 employees with locations in Austria and the USA. LINBIT is an Open Source company offering enterprise-level support subscriptions for its Open Source technologies.

There’s a popular misconception about I/O that (modern) SSDs are easy to deal with; they work pretty much like RAM but use a “legacy” submit-complete API. And other than keeping in mind a disk’s possible peak performance and maybe maintaining priorities of different IO streams there’s not much to care about. This is not quite the case – SSDs do show non-linear behavior and understanding the disk’s real abilities is crucial when it comes to squeezing as much performance from it as possible.
Diskplorer is an open-source disk latency/bandwidth exploring toolset. By using Linux fio under the hood it runs a battery of measurements to discover performance characteristics for a specific hardware configuration, giving you an at-a-glance view of how server storage I/O will behave under load.

E N A B L I N G V I R T U A L I Z E D G RI D S W I T H O R A C L E A...Frank Martin
This white paper discusses how server virtualization using Oracle VM and storage virtualization using NetApp technologies can improve efficiency and reduce costs for Oracle Grid environments. A case study of Oracle University's implementation shows significant benefits, including a 50% reduction in data center space, 40% reduction in power consumption, and transformation of provisioning time from 48 hours to 30 minutes. Virtualization allowed Oracle University to increase the number of hosted events by 200% while maintaining the same administrative staff.
The document discusses Oracle Database Appliance (ODA) high availability and disaster recovery solutions. It compares Oracle Real Application Clusters (RAC), RAC One Node, and Standard Edition High Availability (SEHA). RAC provides automatic restart and failover capabilities for load balancing across nodes. RAC One Node and SEHA provide restart and failover, but no load balancing. SEHA is suitable for Standard Edition databases if up to 16 sessions are adequate and a few minutes of reconnection time is acceptable without data loss during failover.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

3. Introduction to the Private Cloud Appliance
About Private Cloud.
• Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including scalability and self-service, but through a
proprietary architecture.
• Unlike public clouds, which deliver services to multiple organizations, a private cloud is dedicated to the needs and goals of a single
organization. As a result, private cloud is best for businesses with dynamic or unpredictable computing needs that require direct control over
their environments, typically to meet security, business governance or regulatory compliance requirements.
Oracle Private Cloud Appliance (PCA)
• The Oracle Private Cloud Appliance (PCA) is an integrated, ‘wire once’ converged system designed for fast cloud and rapid application
deployments at the data centers. PCA is a one stop system for all your applications, where mixed operating systems (Linux, Solaris, RHEL and
Windows) workloads can be consolidated into a single machine.
• PCA is an offering that industry analysts refer to as a Converged Infrastructure Appliance: an infrastructure solution in the form of a hardware
appliance that comes from the factory pre-configured. It enables the operation of the entire system as a single unit, not a series of individual
servers, network hardware and storage providers. Installation, configuration, high availability, expansion and upgrading are automated and
orchestrated to an optimal degree. Within a few hours after power-on, the appliance is ready to create virtual machines.
• As a converged infrastructure solution, the PCA is built to eliminate many of the intricacies of optimizing the system configuration. Hardware
components are installed and cabled at the factory. Configuration settings and installation software are preloaded onto the system. Once the
appliance is connected to the data center power source and public network, the provisioning process between the administrator pressing the
power button of the first management node and the appliance reaching its Deployment Readiness state is entirely orchestrated by the active
management node.
4. PCA Components
• The PCA hardware platform, with factory-installed
Controller Software Release 2.4.x, consists of an Oracle
Rack Cabinet 1242 base, populated with the hardware
components identified in the diagram and explained
below:
5. Hardware Components
Management Nodes
• At the heart of each PCA installation is a pair of management nodes. They are installed in rack units 5 and 6 and form a
cluster in active/standby configuration for high availability: both servers are capable of running the same services and have
equal access to the system configuration, but one operates as the active while the other is ready to take over the active
functions in case a failure occurs. The active management node runs the full set of services required, while the standby
management node runs a subset of services until it is promoted to the active role.
• The active role is determined at boot through OCFS2 Distributed Lock Management on an iSCSI LUN, which both
management nodes share on the ZFS Storage Appliance installed inside the rack.
• Because rack units are numbered from the bottom up, and the bottom four are occupied by components of the ZFS Storage
Appliance, the active management node is typically the server in rack unit 5. It is the only server that must be powered on
by the administrator in the entire process to bring the appliance online.
• The management nodes share a Virtual IP, where the management web interface can be accessed. This virtual IP is
assigned to whichever server has the active role at any given time.
• The virtual IPs in your environment are as follows:
10.132.224.252 - DR - (Used for demo purposes in this workshop)
10.132.252.252 - Live
6. Compute Nodes
• The compute nodes in the PCA constitute the virtualization platform. The compute nodes provide the processing power and memory capacity for the virtual servers they host.
• Compute nodes are installed with Oracle VM Server 3.4.x and additional packages for Software Defined Networking. When provisioning is complete, the PCA Controller
Software expects all compute nodes in the same rack to be part of the same Oracle VM server pool.
• The PCA Dashboard allows the administrator to monitor the health and status of the compute nodes, as well as all other rack components, and perform certain system
operations. The virtual infrastructure is configured and managed with Oracle VM Manager.
• The PCA offers modular compute capacity that can be increased according to business needs. The minimum configuration of the base rack contains just two compute nodes,
but it can be expanded by one node at a time up to 25 compute nodes.
• Apart from the hardware installation, adding compute nodes requires no intervention by the administrator. New nodes are discovered, powered on, installed and provisioned
automatically by the active management node. The additional compute nodes are integrated into the existing configuration and, as a result, the Oracle VM server pool offers
increased capacity for more or larger virtual machines.
Because of the diversity of possible virtualization scenarios it is difficult to quantify the compute capacity as a number of virtual machines. For sizing guidelines
Storage appliance - Oracle ZFS Storage Appliance ZS7-2
• The Oracle ZFS Storage Appliance ZS7-2, which consists of two controller servers installed at the bottom of the appliance rack and disk shelf about halfway up, fulfills the role
of 'system disk' for the entire appliance. It is crucial in providing storage space for the PCA software.
• A portion of the disk space, 3TB by default, is made available for customer use and is sufficient for an Oracle VM storage repository with several virtual machines, templates
and assemblies. The remaining part of approximately 100TB in total disk space can also be configured as a storage repository for virtual machine resources. Further capacity
extension with external storage is also possible.
Oracle ZFS Storage Appliance ZS7-2 The hardware configuration:
• Two clustered storage heads with two 14TB hard disks each
• One fully populated disk chassis with twenty 14TB hard disks
• Four cache disks installed in the disk shelf: 2x 200GB SSD and 2x 7.68TB SSD
• RAID-1 configuration, for optimum data protection, with a total usable space of approximately 100TB
• The storage appliance is connected to the management subnet (192.168.4.0/24) and the storage subnet (192.168.40.0/24). Both heads form a cluster in active-passive
configuration to guarantee continuation of service in the event that one storage head should fail. The storage heads share a single IP in the storage subnet, but both have an
individual management IP address for convenient maintenance access.
7. The RAID-1 storage pool contains two projects, named OVCA and OVM .
The OVCA project contains all LUNs and file systems used by the PCA software:
• LUNs:
• Locks (12GB) – to be used exclusively for cluster locking on the two management nodes
• Manager (200GB) – to be used exclusively as an additional file system on both management nodes
• File systems:
• MGMT_ROOT – to be used for storage of all files specific to the PCA
• Database – placeholder file system for databases
• Incoming (20GB) – to be used for FTP file transfers, primarily for PCA component backups
• Templates – placeholder file system for future use
• User – placeholder file system for future use
• Yum – to be used for system package updates
• The OVM project contains all LUNs and file systems used by Oracle VM:
• LUNs:
• iscsi_repository1 (3TB) – to be used as Oracle VM storage repository
• iscsi_serverpool1 (12GB) – to be used as server pool file system for the Oracle VM clustered server pool
• File systems:
• nfs_repository1 (3TB) – used by kdump; not available for customer use
• nfs_serverpool1 (12GB) – to be used as server pool file system for the Oracle VM clustered server pool in case NFS is preferred over iSCSI
• In addition to offering storage, the ZFS storage appliance also runs the xinetd and tftpd services. These complement the Oracle Linux services on the active management node
in order to orchestrate the provisioning of all PCA system components.
8. Network Infrastructure
• For network connectivity, the PCA relies on a physical layer that provides the necessary high-availability, bandwidth and speed. On top of this, several different virtual networks
are optimally configured for different types of data traffic. Only the internal administration network is truly physical; the appliance data connectivity uses Software Defined
Networking (SDN).
• The appliance rack contains redundant network hardware components, which are pre-cabled at the factory to help ensure continuity of service in case a failure should occur.
Administration Network
• The administration network provides internal access to the management interfaces of all appliance components. These have Ethernet connections to the Cisco Nexus
9348GC-FXP Switch, and all have a predefined IP address in the 192.168.4.0/24 range. In addition, all management and compute nodes have a second IP address in this
range, which is used for Oracle Integrated Lights Out Manager (ILOM) connectivity.
Data Network
• The appliance data connectivity is built on redundant Cisco Nexus 9336C-FX2 Switches in a leaf-spine design. In this two-layer design, the leaf switches interconnect the rack
hardware components, while the spine switches form the backbone of the network and perform routing tasks. Each leaf switch is connected to all the spine switches, which are
also interconnected. The main benefits of this network architecture are extensibility and path optimization. The PCA rack contains two leaf and two spine switches.
Software Defined Networking
• While the physical data network described above allows the data packets to be transferred, the true connectivity is implemented through Software Defined Networking (SDN).
Using VxLAN encapsulation and VLAN tagging, thousands of virtual networks can be deployed, providing segregated data exchange. Traffic can be internal between resources
within the appliance environment, or external to network storage, applications, or other resources in the data center or on the internet. SDN maintains the traffic separation of
hard-wired connections, and adds better performance and dynamic (re-)allocation. From the perspective of the customer network, the use of VxLANs in PCAance is
transparent: encapsulation and de-encapsulation take place internally, without modifying inbound or outbound data packets. In other words, this design extends customer
networking, tagged or untagged, into the virtualized environment hosted by the appliance.
9. • The Cisco Nexus 9336C-FX2 Switch offers a maximum throughput of 100Gbit per port. The spine switches use 5 interlinks (500Gbit); the leaf switches use 2 interlinks
(200Gbit) and 2x2 crosslinks to the spines. Each compute node is connected to both leaf switches in the rack, through the bond1 interface that consists of two 100Gbit Ethernet
ports in link aggregation mode. The two storage controllers are connected to the spine switches using 4x40Gbit connections.
• For external connectivity, 5 ports are reserved on each spine switch. Four ports are available for custom network configurations; one port is required for the default uplink. This
default external uplink requires that port 5 on both spine switches is split using a QSFP+-to-SFP+ four way splitter or breakout cable. Two of those four 10GbE SFP+ breakout
ports per spine switch, ports 5/1 and 5/2, must be connected to a pair of next-level data center switches, also called top-of-rack or ToR switches.
• During the initialization process of the PCA, several essential default networks are configured:
• The Internal Storage Network is a redundant 40Gbit Ethernet connection from the spine switches to the ZFS storage appliance. All four storage controller interfaces are bonded
using LACP into one datalink. Management and compute nodes can reach the internal storage over the 192.168.40.0/21 subnet on VLAN 3093. This network also fulfills the
heartbeat function for the clustered Oracle VM server pool.
• The Internal Management Network provides connectivity between the management nodes and compute nodes in the subnet 192.168.32.0/21 on VLAN 3092. It is used for all
network traffic inherent to Oracle VM Manager, Oracle VM Server and the Oracle VM Agents.
The Internal Underlay Network provides the infrastructure layer for data traffic between compute nodes. It uses the subnet 192.168.64.0/21 on VLAN 3091. On top of the
internal underlay network, internal VxLAN overlay networks are built to enable virtual machine connectivity where only internal access is required. One such internal VxLAN is
configured in advance: the default internal VM network, to which all compute nodes are connected with their vx2 interface.
The External Underlay Network provides the infrastructure layer for data traffic between PCAance and the data center network. It uses the subnet 192.168.72.0/21 on VLAN
3090. On top of the external underlay network, VxLAN overlay networks with external access are built to enable public connectivity for the physical nodes and all the virtual
machines they host.
• One such public VxLAN is configured in advance: the default external network, to which all compute nodes and management nodes are connected with their vx13040 interface.
Both tagged and untagged traffic are supported by default over this networkThe default external network also provides access to the management nodes from the data center
network and allows the management nodes to run a number of system services. The management node external network settings are configurable through the Network
Settings tab in the PCA Dashboard. If this network is a VLAN, its ID or tag must be configured in the Network Setup tab of the Dashboard.
For the appliance default networking to be configured successfully, three reserved IP addresses are assigned from the data center (public) network range to the management
node cluster of the PCA: one for each management node,(10.132.224.253 & 10.132.224.254)and an additional Virtual IP (10.132.224.252) shared by the clustered nodes.
From this point forward, the Virtual IP is used to connect to the active management node's web server, which hosts both the PCA Dashboard and the Oracle VM Manager web
interface.
10. Software Components
PCA Dashboard - (https://10.132.224.252/dashboard)
• The PCA provides its own web-based graphical user interface that can be used to perform a variety of administrative tasks specific to the appliance. The PCA Dashboard is an
Oracle JET application that is available through the active management node.
• Use the Dashboard to perform the following tasks:
• Appliance system monitoring and component identification
• Initial configuration of management node networking data
• Resetting of the global password for PCA configuration components
Password Manager (Wallet)
• All components of the PCA have administrator accounts with a default password. After applying your data center network settings through the PCA Dashboard, it is
recommended that you modify the default appliance password.
• The Authentication tab allows you to set a new password, which is applied to the main system configuration components. You can set a new password for all listed
components at once or for a selection only.
• Passwords for all accounts on all components are stored in a global Wallet, secured with 512-bit encryption.
11. Oracle VM Manager
• All virtual machine management tasks are performed within Oracle VM Manager, a WebLogic application that is installed on each of the management nodes and which
provides a web-based management user interface and a command line interface that allows you to manage your Oracle VM infrastructure within the PCA.
Oracle VM Manager is comprised of the following software components:
• Oracle VM Manager application: provided as an Oracle WebLogic Server domain and container.
• Oracle WebLogic Server 12c: including Application Development Framework (ADF) Release 12c, used to host and run the Oracle VM Manager application
• MySQL 5.6 Enterprise Edition Server: for the exclusive use of the Oracle VM Manager application as a management repository and installed on the Database file system
hosted on the ZFS storage appliance.
• Administration of virtual machines is performed using the Oracle VM Manager web user interface.
• While it is possible to use the command line interface provided with Oracle VM Manager, this is considered an advanced activity that should only be performed with a thorough
understanding of the limitations of Oracle VM Manager running in the context of an Oracle PCA
Operating Systems
• Hardware components of the PCA run their own operating systems:
• Management Nodes: Oracle Linux 6 with UEK R4
• Compute Nodes: Oracle VM Server 3.4.6
• Oracle ZFS Storage Appliance: Oracle Solaris 11
• All other components run a particular revision of their respective firmware. All operating software has been selected and developed to work together as part of the PCA. When
an update is released, the appropriate versions of all software components are bundled. When a new software release is activated, all component operating software is
updated accordingly. You should not attempt to update individual components unless Oracle explicitly instructs you to!
Databases
• The PCA uses a number of databases to track system states, handle configuration and provisioning, and for Oracle VM Manager. All databases are stored on the ZFS storage
appliance, and are exported via an NFS file system. The databases are accessible to each management node to ensure high availability.
12. List of Databases used by the PCA

13. PCA Management Software
PCA Management Software
• The Oracle PCA includes software that is designed for the provisioning, management and maintenance of all of the components within the appliance.
• The controller software, which handles orchestration and automation of tasks across various hardware components, is not intended for human interaction. Its appliance
administration functions are exposed through the browser interface and command line interface.
Important
• All configuration and management tasks must be performed using the Oracle PCA Dashboard and the Command Line Interface. Do not attempt to run any processes directly
without explicit instruction from an Oracle Support representative. Attempting to do so may render your appliance unusable.
Besides the Dashboard and CLI, this software also includes a number of Python applications that run on the active management node. These applications are found in
/usr/sbin on each management node and some are listed as follows:
• pca-backup: the script responsible for performing backups of the appliance configuration.
• pca-check-master: a script that verifies which of the two management nodes currently has the active role.
• ovca-daemon: the core provisioning and management daemon for the Oracle PCA.
• pca-dhcpd: a helper script to assist the DHCP daemon with the registration of compute nodes.
• pca-diag: a tool to collect diagnostic information from your Oracle PCA.
• pca-factory-init: the appliance initialization script used to set the appliance to its factory configuration. This script does not function as a reset; it is only used for initial rack
setup.
• pca-redirect: a daemon that redirects HTTP or HTTPS requests to the Oracle PCA Dashboard.
• ovca-remote-rpc: a script for remote procedure calls directly to the Oracle VM Server Agent. Currently it is only used by the management node to monitor the heartbeat of the
Oracle VM Server Agent.
• ovca-rpc: a script that allows the Oracle PCA software components to communicate directly with the underlying management scripts running on the management node.
14. Connecting and Logging into the PCA
Connecting & Logging in to the PCA Dashboard
• Monitoring and management of the PCA is achieved using the PCA Dashboard,
which is a web-based graphical user interface.
• To open the Login page of the PCA Dashboard, enter the following address in a
Web browser:
https://manager-vip:7002/dashboard (https://xx.xx.xx.xx:7002/dashboard)
Tip
By using the shared Virtual IP address, you ensure that you always access the
PCA Dashboard on the active management node.
• Enter your PCA Dashboard administration user name in the User Name field.
This is typically the user “admin”. Enter the password for the PCA Dashboard
administration user name in the Password field.
• After you have logged in to the Dashboard successfully, the home page is
displayed. The central part of the page contains Quick Launch buttons that
provide direct access to the key functional areas.
• From every Dashboard window you can always go to any other window by
clicking the Menu in the top-left corner and selecting a different window from the
list. A button in the header area allows you to open Oracle VM Manager.
15. • Enter your PCA Dashboard administration user name in the User Name field.
This is typically the user “admin”. Enter the password for the PCA Dashboard
administration user name in the Password field.
• After you have logged in to the Dashboard successfully, the home page is
displayed. The central part of the page contains Quick Launch buttons that
provide direct access to the key functional areas.
16. Quick Launch Buttons
Hardware View
• The Hardware View window within the PCA Dashboard provides a graphical
representation of the hardware components as they are installed within the rack,
and an accessible tool for troubleshooting hardware components within the PCA
and identifying where these components are actually located within the rack.
• The view of the status of these components is automatically refreshed every 30
seconds by default. You can set the refresh interval or disable it through the
Auto Refresh Interval list. Alternatively, a Refresh button at the top of the page
allows you to refresh the view at any time.
• During particular maintenance tasks, such as upgrading management nodes,
you may need to disable compute node provisioning temporarily. This Disable
CN Provisioning button at the top of the page allows you to suspend
provisioning activity. When compute node provisioning is suspended, the button
text changes to Enable CN Provisioning and its purpose changes to allow you to
resume compute node provisioning as required.
• Rolling over each item in the graphic with the mouse raises a pop-up window
providing the name of the component, its type, and a summary of configuration
and status information. For compute nodes, the pop-up window includes a
Reprovision button, which allows you to restart the provisioning process if the
node becomes stuck in an intermittent state or goes into error status before it is
added to the Oracle VM server pool.
17. Caution
The Reprovision button is to be used only for compute nodes that fail to complete provisioning. For compute nodes that have been provisioned properly and/or host running
virtual machines, the Reprovision button is made unavailable to prevent incorrect use, thus protecting healthy compute nodes from loss of functionality, data corruption, or
being locked out of the environment permanently.
• Alongside each installed component within the appliance rack, a status icon provides an indication of the provisioning status of the component. A status summary is displayed
just above the rack image, indicating with icons and numbers how many nodes have been provisioned, are being provisioned, or are in error status.
• The Hardware View does not provide real-time health and status information about active components. Its monitoring functionality is restricted to the provisioning process.
When a component has been provisioned completely and correctly, the Hardware View continues to indicate correct operation even if the component should fail or be powered
off.
18. Network View - Management Nodes
• The Network Environment window is divided into three tabs: Management
Nodes, Data Center Network, and DNS, as shown and explained below:
• Management Node 1 & 2:
• IP Address: Specify an IP address within your datacenter network that can be
used to directly access each respective management node.
• Host Name: Specify the host name for the first & second management node
systems respectively.
• Management Virtual IP Address: Specify the shared Virtual IP address that is
used to always access the active management node. This IP address must be in
the same subnet as the IP addresses that you have specified for each
management node.
19. Network View - Data Center Network
• Management Network VLAN: The default configuration does not assume that
your management network exists on a VLAN. If you have configured a VLAN on
your switch for the management network, you should toggle the slider to the
active setting and then specify the VLAN ID in the provided field.
Caution
• For systems with Ethernet-based network architecture, a management VLAN
requires additional configuration steps. When a VLAN is used for the
management network, and VM traffic must be enabled over the same network,
you must manually configure a VLAN interface on the vx13040 interfaces of the
necessary compute nodes to connect them to the VLAN with the ID in question.
(Instructions to create a VLAN interface on a compute node, are addressed
seperately in the Oracle VM Administration essentials training.)
• Domain Name: Specify the data center domain that the management nodes
belong to.
• Netmask: Specify the netmask for the network that the Virtual IP address and
management node IP addresses belong to.
• Default Gateway: Specify the default gateway for the network that the Virtual IP
address and management node IP addresses belong to.
• NPT: Specify the NTP server that the management nodes and other appliance
components must use to synchronize their clocks to.
20. Network View - Data Center Network
• DNS Server 1: Specify at least one DNS server that the management nodes can use for domain name resolution.
• DNS Server 2: Optionally, specify a second DNS server.
• DNS Server 3: Optionally, specify a third DNS server.
21. CAUTION
• To avoid network interference and conflicts, you must ensure that the data center network does not overlap with any of the infrastructure subnets of the PCA default
configuration. The following are the subnets and VLANs you should keep clear of:
• Subnets:
• 192.168.4.0/24 – internal machine administration network: connects ILOMs and physical hosts
• 192.168.140.0/24 – internal Oracle VM management network: connects Oracle VM Manager, Oracle VM Server and Oracle VM Agents (applies only to the InfiniBand-based
architecture)
• 192.168.32.0/21 – internal management network: traffic between management and compute nodes
• 192.168.64.0/21 – underlay network for east/west traffic within the appliance environment
• 192.168.72.0/21 – underlay network for north/south traffic, enabling external connectivity
• 192.168.40.0/21 – storage network: traffic between the servers and the ZFS storage appliance
Note
• Each /21 subnet comprises the IP ranges of eight /24 subnets or over 2000 IP addresses. For example: 192.168.32.0/21 corresponds with all IP addresses from 192.168.32.1
to 192.168.39.255.
• VLANs:
• 1 – the Cisco default VLAN
• 3040 – the default service VLAN
• 3041-3072 – a range of 31 VLANs reserved for customer VM and host networks
• 3073-3099 – a range reserved for system-level connectivity
Note
• VLANs 3090-3093 are already in use for tagged traffic over the /21 subnets listed above.
• 3968-4095 – a range reserved for Cisco internal device allocation
22. Monitoring and Managing the PCA
• The PCA Controller Software contains a monitoring service, which is started and stopped with theovca service on the active management node. When the system runs for the
first time it creates an inventory database and monitor database. Once these are set up and the monitoring service is active, health information about the hardware components
is updated continuously.
• The inventory database is populated with information about the various components installed in the rack, including the IP addresses to be used for monitoring. With this
information, the ping manager pings all known components every 3 minutes and updates the inventory database to indicate whether a component is pingable and when it was
last seen online.
• When errors occur they are logged in the monitor database. Error information is retrieved from the component ILOMs.
• For troubleshooting purposes, historic health status details can be retrieved through the CLI support mode by an authorized Oracle Field Engineer. When the CLI is used in
support mode, a number of additional commands are available; two of which are used to display the contents of the health monitoring databases.
i. show db inventory
ii. show db monitor
• Use show db inventory to display component health status information from the inventory database.
• Use show db monitor to display errors logged in the monitoring database.
• The appliance administrator can retrieve current component health status information from the Oracle Linux command line on the active management node, using the PCA
Health Check utility. The Health Check utility is built on the framework of the PCA Upgrader, and is included in the Upgrader package. It detects the appliance network
architecture and runs the sets of health checks defined for the system in question.
23. Checking the Current Health Status of a OPCAInstallation
• Using SSH and an account with superuser privileges, log in to the active
management node.
# ssh root@10.100.1.101
• Launch the Health Check utility.
# pca_healthcheck
PCA Rack Type: PCA X8_BASE.
Please refer to log file
/nfs/shared_storage/pca_upgrader/log/pca_healthcheck_2019_10_04-

...............etc
• Investigate and fix any detected problems. Repeat the health check until the
system passes all checks.
24. Fault Monitoring
• The existing health checker becomes a service, started by the ovca-daemon on
the active management node. Checks can be run manually from the command
line, or using definitions in the scheduler. Depending on the check definition, the
PCA health checker, the Oracle VM health check, and the PCA pre-upgrade
checks can be invoked.
• pca_healthcheck monitors the health of system hardware components. For
more details, refer to the Health Monitoring.
• ovm_monitor monitors the Oracle VM manger objects and other environment
factors.
• pca_upgrader monitors the system during an upgrade.
• The appliance administrator can access current component health status
information from the Oracle Linux command line on the active management
node, using the PCA Fault Monitoring utility.
• The Fault Monitoring utility is included in the ovca services and can be accessed
using the PCA command line on the active management node. In addition, you
can schedule checks to run automatically. The utility detects the appliance
network architecture and runs the sets of health checks defined for that system.
Running Fault Monitor Tests Manually
• The Fault Monitoring utility provides flexibility in that you can choose to run an
individual check, all the check for a particular monitoring service, or all of the
checks available.
Using SSH and an account with superuser privileges, log in to the active
management node.
# ssh root@10.100.1.101
root@10.100.1.101's password:
List available checks.
[root@ovcamn05r1 ~]# pca-faultmonitor --help
[root@ovcamn05r1 faultmonitor]# pca-faultmonitor --
list_pca_upgrader_monitors
Run the desired checks.
• To run all checks.
[root@ovcamn05r1 ~]# pca_faultmonitor --run_all_monitors
• To run a specific check, or a list of specific checks. List one or more checks,
preceeded with -m.
[root@ovcamn05r1 ~]# pca_faultmonitor -m event_monitor -m
check_storage_space
• Run checks for a specific monitor.
[root@ovcamn05r1 ~]# pca_faultmonitor --un_pca_upgrader_monitors
[root@ovcamn05r1 faultmonitor]# pca_faultmonitor run_ovm_monitors
• If certain checks have resulted in failures, review the console or log file for
additional diagnostic information.Investigate and fix any detected problems.
Repeat the check until the system passes all checks.
25. Scheduling Fault Monitor Tests
• By default, the run_ovm_monitors, run_pca_healthcheck_monitors, and
run_pca_upgrader_monitors checks are scheduled to run weekly. You can
change the frequency of these checks or add additional indvidual checks to the
scheduler. You must restart the ovca service to implement any schedule
changes.
• Using SSH and an account with superuser privileges, log in to the active
management node.
# ssh root@10.100.1.101
root@10.100.1.101's password:
root@ovcamn05r1 ~]#
• Change the schedule properties in the ovca-system.conf file. Use the scheduling
format described below.
* * * * * command
- - - - -
| | | | |
| | | | –--- day of week (0-7, Sunday= 0 or 7)
| | | –----- month (1-12)
| | –------- day of month (1-31)
| –--------- hour (0-23)
–----------- minute (0-59)
[root@ovcamn05r1 ~]# cat /var/lib/ovca/ovca-system.conf
[faultmonitor]
report_path: /nfs/shared_storage/faultmonitor/
report_format: json
................etc
Changing Fault Monitoring Options
• Using SSH and an account with superuser privileges, log in to the active
management node.
# ssh root@10.100.1.101
• Change the appropriate property in the ovca-system.conf file.
• The report_format options are json, text, or html.
[root@ovcamn05r1 ~]# cat /var/lib/ovca/ovca-system.conf
ZFS Phone Home service
• Health checking can be integrated with ZFS Phone Home service, where
management nodes collect fault data reports and copy those reports to the ZFS
storage appliance. You can then configure the Phone Home service to push
these reports to Oracle on a weekly basis for monitoring.
• No separate installation is required; all functions come with controller software
in Oracle after installing and activating ASR (Install ASR (Doc ID 2560988.1).
Activating the Phone Home Service for the PCA
• Once ASR is installed on the PCA, you must log in to your My Oracle Service
account and approve the PCA as a new asset. (Doc ID 1329200.1).
• Via SSH, log in to the active management node.
# ssh root@10.100.1.101
• Enable Phone Home in the fault monitoring service by setting the
enable_phonehomeproperty to 1 in the ovca-system.conf file on both
management nodes. (By default, Phone Home is disabled in PCAance).
[root@ovcamn05r1 ~]# edit /var/lib/ovca/ovca-system.conf
• Log in to the ZFS storage appliance browser interface and enable Phone Home.
Go to Configuration > Services > Phone Home and click the power icon to bring
the service online.
• Now your system is configured to send fault reports to Oracle for automated
service response.
26. Networking - Functional Limitations
• There are different levels and areas of network configuration in a PCA environment.
• In terms of functionality, practically all networks operate either at the appliance level or the virtualization level. Each has its own administrative interface: PCA Dashboard and
CLI on the one hand, and Oracle VM Manager on the other. However, the network configuration is not as clearly separated, because networking in Oracle VM depends heavily
on existing configuration at the infrastructure level.
• For example, configuring a new public virtual machine network in Oracle VM Manager requires that the hosts or compute nodes have network ports already connected to an
underlying network with a gateway to the data center network or internet.
• The PCA exists in two different types of network architecture. One is built around a physical InfiniBand fabric; the other relies on physical high speed Ethernet connectivity.
While the two implementations offer practically the same functionality, there are visible hardware and configuration differences. For the purpose ofthis course, we will explore
the latter type.
• Network Configuration of Ethernet-based Systems
• Virtual Machine Network
• By default, a fully provisioned PCA is ready for virtual machine deployment. In Oracle VM Manager you can connect virtual machines to these networks directly:
• default_external, created on the vx13040 VxLAN interfaces of all compute nodes during provisioning
• default_internal, created on the vx2 VxLAN interfaces of all compute nodes during provisioning
• Also, you can create additional VLAN interfaces and VLANs with the Virtual Machine role. For virtual machines requiring public connectivity, use the compute nodes' vx13040
VxLAN interfaces. For internal-only VM traffic, use the vx2 VxLAN interfaces.
Note
Do not create virtual machine networks using the ethx ports. These are detected in Oracle VM Manager as physical compute node network interfaces, but they are not cabled.
Also, the bondxports and default VLAN interfaces (tun-ext, tun-int, mgmt-int and storage-int) that appear in Oracle VM Manager are part of the appliance infrastructure
networking, and are not intended to be used in VM network configurations.
• Virtual machine networking can be further diversified and segregated by means of custom networks, which are described below. Custom networks must be created in the PCA
CLI. This generates additional VxLAN interfaces equivalent to the default vx13040 and vx2. The custom networks and associated network interfaces are automatically set up in
Oracle VM Manager, where you can expand the virtual machine network configuration with those newly discovered network resources.
27. • Custom Network
• Custom networks are infrastructure networks you create in addition to the
default configuration. These are constructed in the same way as the default
private and public networks, but using different compute node network interfaces
and terminating on different spine switch ports. Whenever public connectivity is
required, additional cabling between the spine switches and the next-level data
center switches is required.
• Because they are part of the infrastructure underlying Oracle VM, all custom
networks must be configured through the PCA CLI. The administrator chooses
between three types: private, public or host network.
• If your environment has additional tenant groups, which are separate Oracle VM
server pools, then a custom network can be associated with one or more tenant
groups. This allows you to securely separate traffic belonging to different tenant
groups and the virtual machines deployed as part of them.
• Once custom networks have been fully configured through the PCA CLI, the
networks and associated ports automatically appear in Oracle VM Manager.
There, additional VLAN interfaces can be configured on top of the new VxLAN
interfaces, and then used to create more VLANs for virtual machine connectivity.
The host network is a special type of custom public network, which can assume
the Storage network role and can be used to connect external storage directly to
compute nodes.
Warning
Do not modify the network configuration while upgrade operations are
running. No management operations are supported during upgrade, as
these may lead to configuration inconsistencies and significant repair
downtime.
Warning
Custom networks must never be deleted in Oracle VM Manager. Doing so
would leave the environment in an error state that is extremely difficult to
repair. To avoid downtime and data loss, always perform custom network
operations in the PCA CLI.
Caution - The following network limitations apply:
The maximum number of custom external networks is 7 per tenant group
or per compute node.
The maximum number of custom internal networks is 3 per tenant group
or per compute node.
The maximum number of VLANs is 256 per tenant group or per compute
node.
Only one host network can be assigned per tenant group or per compute
node.
Caution
When configuring custom networks, make sure that no provisioning
operations or virtual machine environment modifications take place. This
might lock Oracle VM resources and cause your PCA CLI commands to
fail.
• Creating custom networks requires use of the CLI. The administrator chooses
between three types: a network internal to the appliance, a network with external
connectivity, or a host network. Custom networks appear automatically in Oracle
VM Manager. The internal and external networks take the virtual machine
network role, while a host network may have the virtual machine and storage
network roles.
• The host network is a particular type of external network: its configuration
contains additional parameters for subnet and routing. The servers connected to
it also receive an IP address in that subnet, and consequently can connect to an
external network device. The host network is particularly useful for direct access
28. • Network Properties
• The network role is a property used within Oracle VM. Most of the networks you configure, have the Virtual Machine role, although you could decide to use a separate network
for storage connectivity or virtual machine migration. Network roles – and other properties such as name and description, which interfaces are connected, properties of the
interfaces and so on – can be configured in Oracle VM Manager, as long as they do not conflict with properties defined at the appliance level.
• Modifying network properties of the VM networks you configured in Oracle VM Manager involves little risk. However, you must not change the configuration – such as network
roles, ports and so on – of the default networks: eth_management, mgmt_internal, storage_internal, underlay_external, underlay_internal, default_external, and
default_internal. For networks connecting compute nodes, including custom networks, you must use the PCA CLI. Furthermore, you cannot modify the functional properties of a
custom network: you have to delete it and create a new one with the required properties.
• The maximum transfer unit (MTU) of a network interface, standard port or bond, cannot be modified. It is determined by the hardware properties or the SDN configuration,
which cannot be controlled from within Oracle VM Manager.
• VLAN Management
• With the exception of the underlay VLAN networks configured through SDN, and the appliance management VLAN you configure in the Network Settings tab of the PCA
Dashboard, all VLAN configuration and management operations are performed in Oracle VM Manager. These VLANs are part of the VM networking.

• When a large number of VLANs is required, it is good practice not to generate them all at once, because the process is time-consuming. Instead, add (or remove) VLANs in
groups of 10.
29. Configuring Custom Networks on Ethernet-based Systems
• This section describes how to configure custom networks on a system with an Ethernet-based network architecture.
• For all networks with external connectivity, the spine Cisco Nexus 9336C-FX2 Switch ports must be specified so that these are reconfigured to route the external traffic. These
ports must be cabled to create the physical uplink to the next-level switches in the data center (Described in detail in the PCA Installation Guide)
Creating a Custom Network on an Ethernet-based System
• Using SSH and an account with superuser privileges, log into the active management node.
# ssh root@10.100.1.101
root@10.100.1.101's password:
root@ovcamn05r1 ~]#
Launch the PCA command line interface.
# pca-admin
Welcome to PCA! Release: 2.4.3
PCA>
For a custom network with external connectivity, configure an uplink port group with the uplink ports you wish to use for this traffic. Select the appropriate breakout mode
PCA> create uplink-port-group MyUplinkPortGroup '1:1 1:2' 10g-4x
Status: Success
Note
• The port arguments are specified as 'x:y' where x is the switch port number and y is the number of the breakout port, in case a splitter cable is attached to the switch port. The
example above shows how to retrieve that information.
30. • If your custom network requires public connectivity, you need to use one or
more spine switch ports. Verify the number of ports available and carefully plan
your network customizations accordingly. The following example shows how to
retrieve that information from your system:
PCA> list network-port

5:3 ovcasw23r1 10G down None
5:4 ovcasw23r1 10G down None
-----------------
22 rows displayed
Status: Success
31. • You must set the breakout mode of the uplink port group. When a 4-way breakout cable is used, all four ports must be set to either 10Gbit or 25Gbit. When no breakout cable is
used, the port speed for the uplink port group should be either 100Gbit or 40Gbit, depending on connectivity requirements. See Section 4.2.18, “create uplink-port-group” for
command details.
• Network ports can not be part of more than one network configuration.
• Create a new network and select one of these types:
• rack_internal_network: an Oracle VM virtual machine network with no access to external networking; no IP addresses are assigned to compute nodes. Use this option to
allow virtual machines additional bandwidth beyond the default internal network.
• external_network: an Oracle VM virtual machine network with access to external networking; no IP addresses are assigned to compute nodes. Usethis option to allow virtual
machines additional bandwidth when accessing external storage on a physical network separate from the default external facing network.
• host_network: an Oracle VM compute node network with access to external networking; IP addresses are added to compute nodes. Use this option to allow compute nodes to
access storage and compute resources external to the PCA. This can also be used by virtual machines to access external compute resources just like external_network.
Use the following syntax:
For an internal-only network, specify a network name.
PCA> create network MyInternalNetwork rack_internal_network
Status: Success
For an external network, specify a network name and the spine switch port group to be configured for external traffic.
PCA> create network MyPublicNetwork external_network MyUplinkPortGroup
Status: Success
For a host network, specify a network name, the spine switch ports to be configured for external traffic, the subnet, and optionally the routing configuration.
PCA> create network MyHostNetwork host_network MyUplinkPortGroup
10.10.10 255.255.255.0 10.1.20.0/24 10.10.10.250(subnet _prefix netmask route_dest route_gateway)
Status: Success
• When you define a host network, it’s possible to enter invalid or contradictory values for the Prefix, Netmask and Route_Destination parameters. e.g. when you enter a prefix
with "0" as the first octet, the system attempts to configure IP addresses on compute node Ethernet interfaces starting with 0. Also, when the netmask part of the route destination you
enter is invalid, the network is still created, even though an exception occurs. Such an “invalid state” network is created, it can’t be reconfigured or deleted with standard commands.
Use the --force option to delete the network.
Caution
Network and routing parameters of a host network cannot be modified. To change these settings, delete the custom network and re-create it with updated settings.
32. Connect the required servers to the new custom network. You must provide the
network name and the names of the servers to connect.
PCA> add network MyPublicNetwork ovcacn07r1
Status: Success
PCA> add network MyPublicNetwork ovcacn08r1
Status: Success
PCA> add network MyPublicNetwork ovcacn09r1
Status: Success
Verify the configuration of the new custom network.
• As a result of these commands, a VxLAN interface is configured on each of the
servers to connect them to the new custom network. These configuration
changes are reflected in the Networking tab and the Servers and VMs tab in
Oracle VM Manager.
Note
If the custom network is a host network, the server is assigned an IP address
based on the prefix and netmask parameters of the network configuration, and
the final octet of the server's internal management IP address.
For example, if the compute node with internal IP address 192.168.4.9 were
connected to the host network used for illustration purposes in this procedure, it
would receive the address 10.10.10.9 in the host network.
The Figure on opposite page shows an Oracle VM Manager View of Custom
Network named MyPublicNetwork, which is VLAN-capable and uses the
compute node's vx13041 interface
• To disconnect servers from the custom network use the remove network command.
Warning
Before removing the network connection of a server, make sure that no virtual
machines are relying on this network.
When a server is no longer connected to a custom network, make sure that its
port configuration is cleaned up in Oracle VM.

33. Deleting Custom Networks
• This section describes how to delete custom networks. The procedure is the
same for systems with an Ethernet-based and InfiniBand-based network
architecture.
Caution
Before deleting a custom network, make sure that all servers have been
disconnected from it first.
Using SSH and an account with superuser privileges, log into the active
management node.
# ssh root@10.100.1.101
root@10.100.1.101's password:

Verify that all servers have been disconnected from the custom network. No vNICs or
nodes should appear in the network configuration.
Caution
Related configuration changes in Oracle VM must be cleaned up as well.
Note
The following command output sample shows a public network configuration on
an Ethernet-based system. The configuration of a public network on an
InfiniBand-based system looks slightly different.

34. Storage Networks
• PCA Administrators can create up to sixteen VM storage networks which can be accessed by any virtual
machine in any tenant group. End users of virtual machines configure their guest operating system to
access one or more of these internal storage networks through NFS or iSCSI once the PCA set up has
been completed. PCA administrators with root access to the management nodes can create and manage
the required networks and ZFS shares (iSCSI/NFS) using the pca-admin command line interface.
• The VM storage networks are designed to isolate different business systems or groups of end users from
each other. For example, the HR department can use two VM storage networks for their virtual machines,
while the payroll department can have three or four VM storage networks of their own. Each VM storage
network is assigned a single, private non-routed VXLAN to ensure the network is isolated from other virtual
machines owned by different end users. End users cannot gain root access to mange the internal ZFS
storage appliance through the VM storage networks.
• The ability to define internal storage networks directly for VM is available in PCA Controller Software release
2.4.3 and above.
35. Tenant Groups
• A tenant group (AKA, Server Pool) is a logical subset of a single PCA environment.
• Tenant groups provide an optional mechanism for a PCA administrator to subdivide the environment in arbitrary ways for manageability and isolation. The tenant group offers a
means to isolate compute, network and storage resources per end customer. It also offers isolation from cluster faults.
Design Assumptions and Restrictions
• A standard PCA environment built on a full rack configuration contains 25 compute nodes. Oracle PCA supports a maximum of 8 tenant groups
• This number includes the default tenant group, which cannot be deleted from the environment, and must always contain at least one compute node.
• Therefore, a single custom tenant group can contain up to 24 compute nodes, while the default Rack1_ServerPool can contain all 25.
• Regardless of tenant group membership, all compute nodes are connected to all of the default PCA networks. Custom networks can be assigned to multiple tenant groups.
When a compute node joins a tenant group, it is also connected to the custom networks associated with the tenant group.
• When you remove a compute node from a tenant group, it is disconnected from those custom networks. A synchronization mechanism, built into the tenant group functionality,
keeps compute node network connections up to date when tenant group configurations change.
• When you reprovision compute nodes, they are automatically removed from their tenant groups, and treated as new servers. Consequently, when a compute node is
reprovisioned, or when a new compute node is added to the environment, it is added automatically to Rack1_ServerPool. After successful provisioning you can then add the
compute node to the appropriate tenant group.
• When you create a new tenant group, the system does not create a storage repository for the new tenant group. An administrator must configure the necessary storage
resources for virtual machines in Oracle VM Manager.
36. Configuring Tenant Groups
• The tenant group functionality can be accessed through the PCA CLI. With a specific set of commands you manage the tenant groups, their member compute nodes, and the
associated custom networks. The CLI initiates a number of Oracle VM operations to set up the server pool, and a synchronization service maintains settings across the
members of the tenant group.
Warning
Do not modify the tenant group configuration while upgrade operations are running. No management operations are supported during upgrade, as these may lead to
configuration inconsistencies and significant repair downtime.
Caution
You must not modify the server pool in Oracle VM Manager because this causes inconsistencies in the tenant group configuration and disrupts the operation of the
synchronization service and the PCA CLI. Only server pool policies may be edited in Oracle VM Manager.
Note
The command output samples in the following section reflect the network configuration on an Ethernet-based system.
37. Creating and Populating a Tenant Group
• Using SSH and an account with superuser privileges, log into the active
management node.
# ssh root@10.100.1.101
• Launch the PCA command line interface.
# pca-admin
Welcome to PCA! Release: 2.4.3
PCA> create tenant-group myTenantGroup
Status: Success
PCA> show tenant-group myTenantGroup
----------------------------------------
The new tenant group appears in Oracle VM Manager as a new server pool. It has a
12GB server pool file system located on the internal ZFS storage appliance.
• Add compute nodes to the tenant group.
• If a compute node is currently part of another tenant group, it is first removed
from that tenant group.
Caution
If the compute node is hosting virtual machines, or if storage repositories are
presented to the compute node or its current tenant group, removing a compute
node from an existing tenant group will fail . If so, you have to migrate the virtual
machines and unpresent the repositories before adding the compute node to a
new tenant group.
PCA> add compute-node ovcacn07r1 myTenantGroup
Status: Success
PCA> add compute-node ovcacn09r1 myTenantGroup
Status: Success
Add a custom network to the tenant group.
PCA> add network-to-tenant-group myPublicNetwork myTenantGroup
Status: Success
38. • Custom networks can be added to the tenant group as a whole. The following
action creates synchronization tasks to configure custom networks on each
server in the tenant group.
Caution
While synchronization tasks are running, make sure that no reboot or
provisioning operations are started on any of the compute nodes involved in the
configuration changes.
• Verify the configuration of the new tenant group.
PCA> show tenant-group myTenantGroup
----------------------------------------
Name myTenantGroup
Default False
Tenant_Group_ID 0004fb00000200008154bf592c8ac33b
Servers ['ovcacn07r1', 'ovcacn09r1']

'default_external', 'default_internal', 'myPublicNetwork']
Pool_Filesystem_ID 3600144f0d04414f400005cf529410003
----------------------------------------
Status: Success
• The new tenant group corresponds with an Oracle VM server pool with the same
name and has a pool file system. The command output also shows that the
servers and custom network were added successfully.
• These configuration changes are reflected in the Servers and VMs tab in Oracle
VM Manager.
Note
The system does not create a storage repository for a new tenant group. An administrator must configure
the necessary storage resources for virtual machines in Oracle VM Manager.
The Figure below shows a second server pool named MyTenantGroup, which contains the two compute
nodes that were added as examples in the course of this procedure.
39. Reconfiguring and Deleting a Tenant Group
• If you inadvertently used Oracle VM Manager to modify a tenant group, the
following section explains the procedure toreconfigure and delete a Tenant
Group. Identify the tenant group you intend to modify:
PCA> list tenant-group

Status: Success
• Remove a network from the tenant group.
• A custom network that has been associated with a tenant group can be removed
again. The command results in serial operations, not using the synchronization
service, to unconfigure the custom network on each compute node in the tenant
group.

• When you remove a compute node from a tenant group, any custom network
associated with the tenant group is automatically removed from the compute
node network configuration. Custom networks that are not associated with the
tenant group are not removed.
Delete the tenant group.
• Before attempting to delete a tenant group, make sure that all compute nodes
have been removed.
• Before removing the last remaining compute node from the tenant group, use
Oracle VM Manager to unpresent any shared repository from the compute node,
and then release ownership of it. (Refere to support note with Doc ID
2653515.1)

group's associated custom networks are not destroyed.
41. Authentication
• The Password Management window of the PCA Dashboard is used to reset the
global PCA password and to set unique passwords for individual components
within the appliance.
• All actions performed via this tab require that you enter the current password for
the PCA admin user in the field labelled Current PCA Admin Password:. Fields
are available to specify the new password value and to confirm the value:
• Current PCA Admin Password: You must provide the current password for the
PCA admin user before any password changes can be applied.
• New Password: Provide the value for the new password that you are setting.
• Verify Password: Confirm the new password and check that you have not mis-
typed what you intended.
• The window provides a series of check boxes that make it easy to select the
level of granularity that you wish to apply to a password change. By clicking
Select All, you can apply a global password to all components that are used in
the appliance. This action resets any individual passwords that you may have
set for particular components.
• Select All: Apply the new password to all components. All components in the
list are selected.
Caution
Password changes are not instantaneous across the appliance, but are
propagated through a task queue. When applying a password change, allow at
least 30 minutes for the change to take effect. Do not attempt any further
password changes during this delay. Verify that the password change has been
applied correctly.
Caution
Passwords of components must not be changed manually as this will cause
mismatches with the authentication details stored in the PCA Wallet.

43. Oracle VM Manager
WARNING!
Warning
• Use of Oracle VM Manager in the context of PCAance, should be limited to the management and creation
of virtual machines!
• Access to the Oracle VM Manager web user interface, command line interface and web services API is
provided without restrictions.
• The configuration of PCA components within Oracle VM Manager is automatic and handled by the PCA
provisioning process. Altering the configuration of these components directly within Oracle VM
Manager is not supported and may result in the malfunction of the appliance!
• The appliance controller software enables customization of networking, external storage connectivity and
server pools – known as tenant groups in PCA. The resulting Oracle VM configurations also must not be
altered within Oracle VM Manager.
• Use of Oracle VM Manager in the context of PCAance should be limited to the management and
creation of virtual machines.
• Configuring additional storage, creating repositories, and setting up additional networks specifically for the
use of virtual machines is possible. However, this should be done carefully, to avoid disrupting the
configuration specific to the PCA.
44. Logging in to the Oracle VM Manager Web UI
• To open the Login page of the Oracle VM Manager Web UI, enter the following address in a Web browser:
https://manager-vip:7002/ovm/console
• Where, manager-vip refers to the virtual IP address, or corresponding host name, that was configured for
the management nodes during installation. By using the virtual IP address, you ensure that you always
access the Oracle VM Manager Web UI on the active management node.
Important
You must ensure that if you are accessing Oracle VM Manager through a firewalled connection, the firewall is configured to allow TCP
traffic on the port that Oracle VM Manager is using to listen for connections.
• Enter your Oracle VM Manager administration user name in the Username field. This is the administration
user name configured during installation. Enter the password for the Oracle VM Manager administration
user name in the Password field.
Important
The Oracle VM Manager Web UI makes use of cookies in order to store session data. Therefore, to successfully log in and use the Oracle
VM Manager Web UI your web browser must accept cookies from the Oracle VM Manager host.
45. Managing the Oracle VM Virtual Infrastructure
• Management of virtual machines and your Oracle VM environment is achieved
using the Oracle VM Manager Web UI (User Interface), available at the virtual
IP address that you configured for your management nodes, and it is configured
to listen for HTTPS requests on port 7002.
• While Oracle VM Manager does provide a command line interface and web
services API, use of these on your PCA should only be attempted by advanced
users with a thorough understanding of Oracle VM, and the usage limitations
within a PCA context.
Note
The information provided in this section, is a description of the Oracle VM
Manager Web UI, within the context of the PCA. Where particular actions within
the Oracle VM Manager Web UI are referenced, separate Oracle VM based
training is recommended.
Guidelines and Limitations
• Below is a non-exhaustive list of critical limitations that are known to be violated
regularly, which results in severe system configuration problems and significant
downtime:
DO NOT rename host names of compute names or other PCA components.
DO NOT rename server pools.
DO NOT rename built-in repositories.
DO NOT rename existing networks or modify their properties (VLAN tag, MTU,
and so on), except as documented explicitly in the PCA Administrator's Guide.
DO NOT add the VM role to the internal management network or internal
storage network.
• Also on the next slide, is a list operations that are explicitly not permitted,
presented as guidelines and limitations that should be followed when working
within Oracle VM Manager, or executing operations programmatically through
the command line interface (CLI) or web services API (WSAPI).
46. • The following actions must not be performed, except if Oracle gives specific instructions to do so.
Do Not:
attempt to discover, remove, rename or otherwise modify servers or their configuration;
attempt to modify the NTP configuration of a server;
attempt to add, remove, rename or otherwise modify server pools or their configuration;
attempt to change the configuration of server pools corresponding with tenant groups configured through the appliance controller software (except for DRS policy setting);
attempt to move servers out of the existing server pools, except when using the pca-admin commands for administering tenant groups;
attempt to add or modify or remove server processor compatibility groups;
attempt to modify or remove the existing local disk repositories or the repository named Rack1-repository;
attempt to delete or modify any of the preconfigured default networks, or custom networks configured through the appliance controller software;
attempt to connect virtual machines to the appliance management network;
attempt to modify or delete any existing Storage elements that are already configured within Oracle VM, or use the reserved names of the default storage elements – for
example OVCA_ZFSSA_Rack1 – for any other configuration;
attempt to configure global settings, such as YUM Update, in the Reports and Resources tab (except for tags, which are safe to edit);
attempt to select a non-English character set or language for the operating system, because this is not supported by Oracle VM Manager – see support note with Doc ID
2519818.1;
attempt to connect any PCA component to a customer's LDAP or Active Directory for authentication, including management nodes, compute nodes, ZFS storage appliances,
NIS, NIS+, and other naming services;
attempt to add users – for example – adding users to management nodes or to WebLogic;
attempt to change DNS settings on compute nodes or ZFS storage appliances. The PCA dashboard contains the only permitted DNS settings.
change settings on Ethernet or InfiniBand switches integrated into the PCA or Oracle Private Cloud at Customer.
If you ignore this advice, the PCA automation, which uses specific naming conventions to label and manage assets, may fail. Out-of-band configuration changes would not be
known to the orchestration software of the PCA. If a conflict between the PCA configuration and Oracle VM configuration occurs, it may not be possible to recover without data
loss or system downtime.
Note
An exception to these guidelines applies to the creation of a Service VM. support note with Doc ID 2017593.1.) support note with Doc ID 2510822.1.)

48. Monitoring Health and Performance in Oracle VM
• The Health tab provides a view of the health of the compute nodes and the server pool within your environment. This information complements the Hardware View provided in
the PCA Dashboard.
• The Statistics subtabs available on the Health tab provides statistical information, including graphs that can be refreshed with short intervals or at the click of a button, for CPU
and memory usage and for file system utilization. These statistics can be viewed at a global scale to determine overall usage, or at the detail level of a category of resources or
even a single item.
• The Server and VM Statistics subtab can display information per server to see the performance of each individual compute node, or per virtual machine to help track the
usage and resource requirements for any of the virtual machines within your environment. The File System Statistics subtab displays storage space utilization information,
organized by storage location, and allows you to track available space for individual file systems over time.
• In addition to the Health tab you can also monitor the status of many resource categories through the Info perspective or Events perspective. When you select these
perspectives in the Management pane, the type of information displayed depends on the active item in the Navigation pane on the left hand side. Both the Info perspective and
the Events perspective are common to many elements within the Oracle VM Manager Web UI.
Creating and Managing Virtual Machines
• The Servers and VMs tab is used to create and manage your virtual machines.
• By default, compute nodes in the base rack of the appliance are listed as belonging to a single server pool called Rack1_ServerPool.
• The configuration of the default server pool must NOT be altered. There is no need to discover servers, as compute nodes are automatically provisioned and discovered within
a PCA. Editing the configuration of the server pool, servers and processor compatibility groups is not supported. The primary purpose of this tab within the PCA context is to
create and manage your virtual machines.

Virtual machine templates (by cloning a template)
Existing virtual machines (by cloning a virtual machine)
Virtual machine assemblies or virtual appliances
• Virtual machines require most installation resources to be located in the storage repository, managed by Oracle VM Manager, with the exception of mounted ISO files for
paravirtualized guests.
The following list provides an outline of actions that you can perform in this tab. More emphasis on this is made during the Oracle VM based trainings.
Create a virtual machine, You need only ensure that your installation media has been correctly imported into the PCA repository.
View virtual machine information and events, Edit, Start a virtual machine and Connect to a virtual machine console
Stop, Kill, Restart , Suspend, Resume a virtual machine
Migrate or move a virtual machine between repositories, between servers, and to or from the Unassigned Virtual Machines folder
Control virtual machine placement through anti-affinity groups.
You can prevent virtual machines from running on the same physical host by adding them to an anti-affinity group. This is particularly useful for redundancy and load balancing
purposes.
Anti-Affinity Groups are discussedin detail in the Oracle VM training.
Clone a virtual machine, You can create a clone customizer to set up the clone parameters, such as networking, and the virtual disk, and ISO resources.
Export virtual machines to a virtual appliance, to OCI, (OVM Exporter Appliance), Send a message to a VM, and lastly but not least, Delete a VM!
50. Managing Virtual Machine Resources
• The Repositories tab provides a view of the PCA repository. By default, a shared repository is configured on the internal ZFS storage applianc
e and named Rack1-repository.
Additional local repositories are configured using the free disk space of each compute node. None of the default repository configurations may be altered.
Caution
Using local storage on the compute nodes has implications that you should take into account when planning the deployment of your virtual environment. For example:
Virtual machines with resources in a local storage repository cannot be migrated to another compute node.
Templates, assemblies and ISOs in local storage repositories cannot be used to create virtual machines on another compute node.
If a compute node becomes unavailable, its locally stored virtual machines and resources cannot be restored or migrated to another compute node for continued service.
• The virtual machines and resources in local storage repositories are not protected by automatic failover and high-availability mechanisms normally offered by a clustered
Oracle VM server pool with shared storage repository.
• Additional repositories should be configured using external storage solutions. If the system contains an Oracle ZFS Storage Appliance ZS7-2, extra disk trays can be installed
to provide the space for additional repositories.
The Repositories tab is used to manage virtual machine resources, such as installation media and virtual disks. From this tab, it is possible to create, import or clone Oracle VM
templates, virtual appliances and ISO image files. It is also possible to create, modify, or clone virtual disks here. The following list provides an outline of actions that you can
perform in this tab:
Manage Virtual Machine Templates: Import, Edit, Clone, Move, Delete a template and manage template clone customisers
Manage Virtual Appliances: Create a VM from a virtual appliance, Edit, Refresh, Delete a virtual appliance
Manage Virtual Machine ISO Image Files: Import, Edit, Clone, Delete an ISO
Manage Virtual Disks: Create, Import, Edit, Clone, Delete a virtual disk

Virtual Appliances from Oracle
• Through the Oracle VM product pages, you can find several pre-configured Oracle VM Virtual Appliances, which can be downloaded for convenient deployment on the PCA.
These virtual appliances allow users of PCA to rapidly set up a typical Oracle product stack within their Oracle VM environment, without having to perform the full installation
and configuration process.
For specific information about virtual appliances offered through Oracle Technology Network, refer to Virtual Appliances from Oracle.
51. Configuring Network Resources for Virtual Machines
• The Networking tab is used to manage networks within the Oracle VM
environment running on the PCA.
Caution
By default, a number of networks are defined during factory installation. These
must not be altered as they are required for the correct operation of the PCA
software layer.
• The PCA exists in two different types of network architecture. One is built
around a physical InfiniBand fabric; the other relies on physical high speed
Ethernet connectivity. While the two implementations offer practically the same
functionality, the configuration of default networks is different due to the type of
network hardware. As a result, the procedures to create VLAN networks for
virtual machine traffic are different as well.
• This training focuses on the latter type of connectivity, physical high speed
Ethernet
• On such a system with an Ethernet-based network architecture, default
networks are set up as follows:
192.168.32.0 : the internal management network
• This is a private network providing connectivity between the management nodes
and compute nodes, using VLAN 3092. It is used for all network traffic inherent
to Oracle VM Manager, Oracle VM Server and the Oracle VM Agents.
192.168.40.0 : the internal storage network
• This is a private network used exclusively for traffic to and from the ZFS storage
appliance. Both management nodes and compute nodes can reach the internal
storage on VLAN 3093. The network also fulfills the heartbeat function for the
clustered Oracle VM server pool.
• Additionally, two networks are listed with the VM Network role:
i. default external
ii. default internal
52. i. default_external
• This default network is the standard choice for virtual machines requiring external network connectivity. It supports both tagged and untagged traffic. For untagged traffic it uses
the Oracle VM standard VLAN 1, meaning no additional configuration is required.
• If you prefer to use VLANs for your VM networking, configure the additional VLAN interfaces and networks of your choice as follows:
Go to the Networking tab and select the VLAN Interfaces subtab.
• The process for creating VLAN Interfaces is described in detail in the Oracle VM Manager User's Guide in the section entitled Create VLAN Interfaces.
• Click Create VLAN Interface. In the navigation tree of the Create VLAN Interfaces window, select the vx13040 VxLAN interface of each compute node in the default
Rack1_ServerPool.
• In the next step of the wizard, add the VLAN IDs you require. When you complete the wizard, a new VLAN interface for each new VLAN ID is configured on top of each
compute node interface you selected.
• Create a new Oracle VM network with the VM role, on the VLAN interfaces for each VLAN tag you created. Each new network should contain the VLAN interfaces associated
with a particular VLAN ID; for example all VLAN interfaces with ID 11 on top of a vx13040 interface.
• Configure your data center network accordingly.
ii. default_internal
• This default network is intended for virtual machines requiring network connectivity to other virtual machines hosted on the appliance, but not external to the appliance. For
untagged traffic it uses the Oracle VM standard VLAN 1. To use the VLANs of your choice, configure the additional VLAN interfaces and networks as follows:
Go to the Networking tab and select the VLAN Interfaces subtab.
• The process for creating VLAN Interfaces is described in detail in the Oracle VM Manager User's Guide in the section entitled Create VLAN Interfaces.
• Click Create VLAN Interface. In the navigation tree of the Create VLAN Interfaces window, select the vx2 VxLAN interface of each compute node in the default
Rack1_ServerPool.
• In the next step of the wizard, add the VLAN IDs you require. When you complete the wizard, a new VLAN interface for each new VLAN ID is configured on top of each
compute node network port you selected.
• Create a new VLAN network with the VM role for each VLAN tag you added. Each new network should contain the VLAN interfaces associated with a particular VLAN ID; for
example all VLAN interfaces with ID 1001 on top of a vx2 interface.
53. Note
When reprovisioning compute nodes or provisioning newly installed compute nodes, you always need to configure VLANs manually. The VLAN configuration is not applied
automatically when the compute node joins an existing server pool.
Note
To start using the new network at the VM level, edit the necessary VMs and assign a VNIC to connect to the new network.
Tip
You can filter the VLAN interfaces by ID to simplify the selection of the VLAN interfaces participating in the new network.
Note
The process for creating networks with VLAN interfaces is described in more detail in the Oracle VM Manager training.
Caution
Do not alter the internal appliance administration network (192.168.4.0) connections on the compute nodes or any other rack components. The environment infrastructure
depends on the correct operation of this network.
DO NOT edit or delete any of the networks listed here. Doing so may cause your appliance to malfunction. In an PCA context, use the Networking tab to configure and manage
Virtual NICs and VLANs for use by your virtual machines.
Create a new VLAN network with the VM role for each VLAN tag you added. Each new network should contain the VLAN interfaces associated with a particular VLAN ID; for
example all VLAN interfaces with ID 1001 on top of a vx2 interface.
54. Viewing and Managing Storage Resources
• The storage resources underlying the built-in PCA ZFS storage repository and
the server pool clustering file system are listed under the Storage tab within
Oracle VM Manager. The internal ZFS storage is listed under the SAN Servers
folder. Do not modify or attempt to delete this storage.
Warning
Compute node provisioning relies on the internal ZFS file server and its exported
storage. Changing the configuration will cause issues with provisioning and
server pool clustering.
• There are functional differences between the Oracle ZFS Storage Appliance
ZS7-2, which is part of systems with an Ethernet-based network architecture,
and the previous models of the ZFS Storage Appliance, which are part of
systems with an InfiniBand-based network architecture. For clarity, this training
describes the ZFS Storage Appliance ZS7-2, which is part of systems with an
Ethernet-based network architecture.
• The internal ZFS Storage Appliance has sufficient disk space (100TB) for a
basic virtualized environment, but the storage capacity for virtual disks and
shared file systems can be extended with additional external storage for use
within Oracle VM.
• You are also fully capable of using other networked storage, available on the
public network or a custom network, within your own Virtual Machines.
Note
More nformation on expanding your Oracle VM environment with storage
repositories located on the external storage is available via the Oracle VM
training.

55. Tagging Resources in Oracle VM Manager
The Reports and Resources tab is used to configure global settings for Oracle VM and to manage tags, which can be used to identify and group resources.
• Since many of the global settings such as server update management and NTP configuration are managed automatically withinPCAiance, you do not need to edit any settings
here. Those configuration changes could cause the appliance to malfunction.
• You can also use this tab to generate XML reports about Oracle VM objects and attributes
Managing Jobs and Events
• The Jobs tab provides a view of the job history within Oracle VM Manager. It is used to track and audit jobs and to help troubleshoot issues within the Oracle VM environment.
Jobs and events are described in detail within the Oracle VM training.
• However, the Recurring Jobs, described in detail within the Oracle VM training, are all automated and handled directly by the PCA, and therefore you must NOT edit any of the
settings for recurring jobs.
56. PCA Backup
Internal Backup
• The configuration of all components within the PCA is automatically backed up and stored on the ZFS storage appliance as a set of archives. Backups are named with a time
stamp for when the backup is run.
• During initialization, a crontab entry is created on each management node to perform a global backup twice in every 24 hours. The first backup runs at 09h00 and the second at
21h00. Only the active management node actually runs the backup process when it is triggered.
• Backups are stored on the MGMT_ROOT file system on the ZFS storage appliance and are accessible on each management node at /nfs/shared_storage/backups. When the
backup process is triggered, it creates a temporary directory named with the time stamp for the current backup process. The entire directory is archived in a *.tar.bz2 file when
the process is complete. Within this directory several subdirectories are also created:
data_net_switch: used only on systems with Ethernet-based network architecture; contains the configuration data of the spine and leaf switches
mgmt_net_switch: used only on systems with Ethernet-based network architecture; contains the management switch configuration data
nm2: used only on systems with InfiniBand-based network architecture; contains the NM2-36P Sun Datacenter InfiniBand Expansion Switch configuration data
opus: used only on systems with InfiniBand-based network architecture; contains the Oracle Switch ES1-24 configuration data
ovca: contains all of the configuration information relevant to the deployment of the management nodes such as the password wallet, the network configuration of the
management nodes, configuration databases for PCAance services, and DHCP configuration.
ovmm: contains the most recent backup of the Oracle VM Manager database, the actual source data files for the current database, and the UUID information for the Oracle VM
Manager installation. Note that the actual backup process for the Oracle VM Manager database is handled automatically from within Oracle VM Manager. Manual backup and
restore are described in detail in the section entitled Backing up and Restoring Oracle VM Manager, in the Oracle VM Manager Administration Guide.
ovmm_upgrade: contains essential information for each upgrade attempt. When an upgrade is initiated, a time-stamped subdirectory is created to store the preinstall.log file
with the output from the pre-upgrade checks. Backups of any other files modified during the pre-upgrade process, are also saved in this directory.
xsigo: used only on systems with InfiniBand-based network architecture; contains the configuration data for the Fabric Interconnects.
zfssa: contains all of the configuration information for the ZFS storage appliance.
