  32. 32. About VMFS6 • VMFS6: – Allows concurrent access to shared storage. – Can be dynamically expanded. – Uses 1 MB sizes that are good for storing large virtual disk files. – Uses subblock addressing that is good for storing small files: the subblock size is 8 KB. – Provides on-disk locking. HostHost VMFS Datastore Torino 9 febbraio 2017
  33. 33. Automated UNMAP • UNMAP is a vSphere Storage APIs primitive that enables reclamation of dead or stranded space on thinly provisioned VMFS volumes. • In vSphere 6.0, this can be initiated by running a simple ESXCLI command that can free up deleted blocks from storage. vSphere 6.5 automates the UNMAP process by which VMFS tracks the deleted blocks and reclaims deleted space from the backend array in background. • This background operation ensures a minimal storage I/O impact due to UNMAP operations. UNMAP works at a guest OS level with newer versions of Windows and Linux. Torino 9 febbraio 2017
  34. 34. LUN Scalability • In vSphere 6 the maximum number of LUNs is 256 and paths is 1,024 • vSphere 6.5 now supports up to 512 LUNs and 2,000 paths Torino 9 febbraio 2017

Network Switch and Port Policies • Policies that are set at the standard switch level apply to all port groups on the standard switch by default. • Available network policies: – Security – Traffic shaping – NIC teaming and failover • Policies are defined at the following levels: – Standard switch level: • Default policies for all the ports on the standard switch. – Port group level: • Effective policies: Policies defined at this level override the default policies that are set at the standard switch level. • Torino 9 febbraio 2017
  40. 40. Configuring Security Policies – Promiscuous mode: Allows a virtual switch or port group to forward all traffic regardless of the destination. – MAC address changes: Accept or reject inbound traffic when the MAC address is altered by the guest. – Forged transmits: Accept or reject outbound traffic when the MAC address is altered by the guest. Torino 9 febbraio 2017
  41. 41. Traffic-Shaping Policy • Network traffic shaping is a mechanism for limiting a virtual machine’s consumption of available network bandwidth. • Average rate, peak rate, and burst size are configurable. Peak Bandwidth Average Outbound Bandwidth Time Burst Size = Bandwidth x Time Torino 9 febbraio 2017

  53. 53. Customizing the Guest Operating System • Use the Guest Operating System Customization wizard to make virtual machines created from the same template or clone unique. – Customizing a guest operating system enables you to change: • Computer name • Network settings • License settings • Windows Security Identifier • During cloning or deploying virtual machines from a template: – You can create a specification to prepare the guest operating systems of virtual machines. – Specifications can be stored in the database. – You can edit specifications in the Customization Specifications Manager. – Windows and Linux operating systems are supported. Torino 9 febbraio 2017
  54. 54. Migrating Virtual Machines • Migration means moving a virtual machine from one host, datastore, or vCenter Server system to another host, datastore, or vCenter Server system. – Types of migrations: • Cold: Migrate a powered-off virtual machine to a new host or datastore. • Suspended: Migrate a suspended virtual machine to a new host or datastore • vSphere vMotion: Migrate a powered-on virtual machine to a new host. • vSphere Storage vMotion: Migrate a powered-on virtual machine's files to a new datastore. • Shared-nothing vSphere vMotion: Migrate a powered-on virtual machine to a new host and a new datastore simultaneously. Torino 9 febbraio 2017

  56. 56. Resource Management and Monitoring
  57. 57. Memory Reclamation Techniques • Economize use of physical memory pages: – Transparent page sharing allows pages with identical contents to be stored only once. • Deallocate memory from one virtual machine for another: – Ballooning mechanism, active when memory is scarce, forces virtual machines to use their own paging areas. • Memory compression: – Attempts to reclaim some memory performance when memory contention is high. • Host-level SSD swapping: – Use of a solid-state drive (SSD) on the host for a host cache swap file might increase performance. • Page virtual machine memory out to disk: – Use of VMkernel swap space is the last resort, because of poor performance.

  65. 65. vSphere HA
  66. 66. About Clusters A cluster is used in vSphere to share physical resources between a group of ESXi hosts. vCenter Server manages cluster resources as a single pool of resources. Features such as vSphere HA, vSphere DRS, and vSAN can be enabled in a cluster. Cluster Torino 9 febbraio 2017
  67. 67. About vSphere HA Protects against ESXi host failures Protects against application failures Protects against datastore accessibility failures Protects virtual machines against network isolation Torino 9 febbraio 2017

Requires installation of VMware Tools. Virtual Machine C Application Virtual Machine F Application Virtual Machine D Application Virtual Machine A Application Virtual Machine B Application = vSphere HA Cluster Torino 9 febbraio 2017
  71. 71. Proactive HA • Proactive HA integrates with select hardware partners to detect degraded components and evacuate VMs from affected vSphere hosts before an incident causes a service interruption. • Hardware partners offer a vCenter Server plug-in to provide the health status of the system memory, local storage, power supplies, cooling fans, and network adapters. As hardware components become degraded, Proactive HA determines which hosts are at risk and places them into a new state, Quarantine Mode. While in Quarantine Mode, VMs are migrated to healthy hosts, as long as affinity or antiaffinity rules are not violated and there is no impact to VM performance. In addition, the affected hosts are avoided when new VMs are added to the cluster. Torino 9 febbraio 2017
  72. 72. High Availability Orchestrated Restart Torino 9 febbraio 2017 • Orchestrated Restart improves the recoverability of applications that run across multiple VMs. • This is done by creating dependency chains between VMs via VM-to-VM restart rules. • These restart rules enforce the restart order for each VM within the dependency chain, increasing the likelihood that an impacted application will properly recover when vSphere HA restarts the VMs.
  73. 73. Configuring vSphere HA Settings • When you create a vSphere HA cluster or configure a cluster, you must configure settings that determine how the feature works. Torino 9 febbraio 2017
  74. 74. vSphere HA Admission Control Improvements Torino 9 febbraio 2017

  78. 78. vSphere DRS
  79. 79. vSphere DRS Cluster Prerequisites Torino 9 febbraio 2017
  80. 80. vSphere DRS : Automation Level Migration threshold guides selection of virtual machines for migration. Automation Level Settings Torino 9 febbraio 2017
  81. 81. Predictive DRS (1) In addition to current usage metrics, vSphere DRS initiation also depends on predicted usage metrics provided by vRealize Operations. Torino 9 febbraio 2017
  82. 82. Predictive DRS • Predictive DRS is a new feature that leverages the predictive analytics of vRealize Operations Manager with the powerful resource scheduler algorithm of vSphere DRS. Together, these two products enable workload balancing for certain VMs before resource utilization spikes occur, potentially eliminating a great amount of resource contention that might have occurred in the past. • vRealize Operations Manager runs its dynamic thresholds algorithm nightly against the VMs on which it collects data. These dynamic thresholds create forecasted metrics for the future utilization of the VMs. • The metrics are then passed to vSphere DRS to determine the best placement and balance of VMs before resource utilization spikes occur. Predictive DRS helps prevent resource contention on hosts that run VMs with predictable utilization patterns. Torino 9 febbraio 2017
