10. Misc

11. Update Manager Features
• VM patching REMOVED
• Optimized Cluster Patching and Upgrade:
– Based on available cluster capacity, it can remediate an optimal number of
ESX/ESXi servers simultaneously without virtual machine downtime.
– For those scenarios where turnaround time is more important than virtual
machine uptime, you have the choice to remediate all ESX servers in a cluster
simultaneously.
• Less Downtime for VMware Tools Upgrade
– can schedule an upgrade to occur at the time of next virtual machine reboot.
• New Update Manager Utility:
– helps users reconfigure the setup of Update Manager
– change the database password and proxy authentication
– replace the SSL certificates for Update Manager.

12. Update Manager: ESX to ESXi Migration
• Supported Paths
– Migration from ESX (“Classic”) 4.x to ESXi 5.0
– For VUM-driven migration, pre-4.x hosts will have to be upgraded to 4.x first
• Might be better just to do fresh install of ESXi 5.0
• Preservation of Configuration Information
– Most standard configurations will be preserved, but not all:
• Information that’s not applicable to ESXi will not be preserved, e.g.
– /etc/yp.conf (no NIS in ESXi)
– /etc/sudoers (no sudo in ESXi)
• Any additional custom configuration files will not be preserved, e.g.
– Any scripts added to /etc/rc.d

27. Selecting a Storage Profile during provisioning
By selecting a VM Storage Profile, datastores are now split into
Compatible & Incompatible.
The Celerra_NFS datastore is the only datastore which meets the GOLD
Profile requirements – i.e. it is the only datastore that has our user-
defined storage capability associated with it.

29. Software FCoE Adapters
• A software FCoE adapter is a software code that performs some of the
FCoE processing.
• This adapter can be used with a number of NICs that support partial FCoE
offload.
• Unlike the hardware FCoE adapter, the software adapter needs to be
activated, similar to Software iSCSI.

31. Storage DRS
Storage DRS provides the following:
1. Initial Placement of VMs and VMDKS based on available space and I/O
capacity.
2. Load balancing between datastores in a datastore cluster via Storage
vMotion based on storage space utilization.
3. Load balancing via Storage vMotion based on I/O metrics, i.e. latency.

32. Datastore Cluster
• An integral part of SDRS is to create a group of datastores called a
datastore cluster.
• Datastore Cluster without Storage DRS – Simply a group of datastores.
• Datastore Cluster with Storage DRS - Load Balancing domain similar to a DRS
Cluster.
• A datastore cluster , without SDRS is just a datastore folder. It is the
functionality provided by SDRS which makes it more than just a folder.

VMDK affinity
 Keep a Virtual Machine’s
VMDKs together on the same
datastore
 Maximize VM availability
when all disks needed in
order to run
 On by default for all VMs
VMDK anti-affinity
 Keep a VM’s VMDKs on
different datastores
 Useful for separating log
and data disks of database
VMs
 Can select all or a subset of
a VM’s disks
Datastore Cluster
VM anti-affinity
 Keep VMs on different
datastores
 Similar to DRS anti-affinity
rules
 Maximize availability of a
set of redundant VMs

36. So what does it look like? Load Balancing
• It will show “utilization before” and “after”
• There’s always the option to override the recommendations

37. VSA
vSphere Storage Appliance

38. Introduction
• Each ESXi server has a VSA deployed to it as a Virtual Machine.
• The appliances use the available space on the local disk(s) of the ESXi servers &
present one replicated NFS volume per ESXi server. This replication of storage
makes the VSA very resilient to failures.

49. 802.1p Tag for Resource Pool
• vSphere infrastructure does not provide QoS based on these tags.
• vDS simply tags the packets according to the Resource Pool setting, and it
is down to the physical switch to understand the flag and act upon it.

50. High Availability

51. HA
vSphere HA feature provides organizations the ability to run their critical
business applications with confidence.
Enhancements allow:
• A solid, scalable foundation upon which to build to the cloud
• Ease of management
• Ease of troubleshooting
• Increased communications mechanisms
VMware ESX VMware ESX VMware ESXi
Resource Pool
Failed Server Operating ServerOperating Server

52. vSphere HA Primary Components
• Every host runs a agent
– Referred to as ‘FDM’ or Fault Domain
Manger
– One of the agents within the cluster is
chosen to assume the role of the Master
– All other agents assume the role of Slaves
• There is no more Primary/Secondary
concept with vSphere HA
– There is only one Master per cluster during
normal operations

ESX 04

53. Storage Level Communications
• One of the most exciting new features of
vSphere HA is its ability to use a storage
subsystem for communication.
• The datastores used for this are referred to as
‘Heartbeat Datastores’.
• Heartbeat datastores are used as a
communication channel only when the
management network is lost - such as in the
case of isolation or network partitioning.

54. Data Recovery

55. vDR: Deduplication Performance Improvements
Overall Improvements
1. New compression algorithm will speed up compressing of data
2. More efficient IO path when accessing slab files
3. Group transactions together with parent (i.e. daily backups of the same VMs
stored in same slab file)
Integrity Check Improvements
1. Periodic checkpoints allows suspending and resuming IC operation
2. Group similar transactions together so they can be processed in bulk
3. Additional tweaking of IC options via datarecovery.ini file (for example, what day
you want the full integrity check to run and frequency per month)

56. Email Reports – Sample
Good backup –
no errors

57. Supported Environment
• VMware vSphere vCenter 4.1 Update 1 and later
• VMware vSphere 4.0 Update 3 and later

58. vDR: Destination Maintenance
Allows separation of backup and maintenance windows. Some use cases
1) Delay start of integrity checks so backups complete as expected
2) Ensure no activity on dedupe store so files can be safely copied off to alternate media

59. Ability To Suspend Backup Jobs
• Backup Job can be suspended individually
• Right click backup job and select Suspend Future Tasks
• Currently running tasks are not affected

60. New datarecovery.ini options
Option Description Range

80. vSphere Replication 1.0 Limitations
• Focus on virtual disks of powered-on VMs.
– ISOs and floppy images are not replicated.
– Powered-off/suspended VMs not replicated.
– Non-critical files not replicated (e.g. logs, stats, swap, dumps).
• vSR works at the virtual device layer.
– Snapshots work with vSR, snapshot is replicated, but VM is recovered with
collapse snapshots.
– Physical RDMs are not supported.
• FT, linked clones, VM templates are not supported with vSR.
• Automated failback of vSR-protected VMs will be late, but will be
supported in the future.
• Virtual Hardware 7, or later, in the VM is required.

82. Planned Migrations = Consistency & No Data Loss
Overview
Benefits
Two workflows can be applied to recovery plans:
 DR failover
 Planned migration
Planned migration ensures application
consistency and no data-loss during migration
 Graceful shutdown of production VMs in
application consistent state
 Data sync to complete replication of VMs
 Recover fully replicated VMs
Better support for planned migrations
 No loss of data during migration process
 Recover ‘application-consistent’ VMs at
recovery site
Planned Migration

83. Reprotect
 After you use planned migration (or DR Event) to migrate to your recovery
site, you must reprotect to enable the failback.

84. Simplify failback process
 Automate replication management
 Eliminate need to set up new recovery plan
