Hyper-V High-Availability Best Practices with Failover Clustering
Tweet Share
This technical session discusses Windows Server 2012 R2 Hyper-V and Failover Clustering design, infrastructure planning and deployment considerations for your highly-available datacenter or Private Cloud. Symon Perriman, Microsoft's Senior Technical Evangelist and cluster expert, discusses the pros and cons of how different solutions can provide continuous availability to virtualized environments with a focus on Failover Clustering. Learn how Windows Server 2012 R2 moves the datacenter closer to a hybrid cloud implementation, while offering persistent availability from both planned and unplanned downtime. Prior clustering and Hyper-V knowledge recommended.

Cluster-on-a-cluster does increase complexity
Mixing physical and virtual nodes is supported
Must pass Validate
It is fully supported to combine both physical and virtual clusters, so long as everything passes Validate
This actually gives the highest availability possible since both VMs and the apps within them are clustered

17. Enable VM Health Monitoring
Enable VM heartbeat setting
Requires Integration Components (ICs) installed in VM
Health check for VM OS from host
User-Mode Hangs
System Crashes
CLUSTER
Shared Storage
Also in Windows Server 2008 R2

18. Disable Starting Low Priority VMs
‘Auto Start’ setting configures if a VM should be automatically started on failover
Group property
Disabling mark groups as lower priority
Enabled by default
Disabled VMs needs manual restart to recover after a crash
Also in Windows Server 2008 R2

19. Keep VMs on Preferred Hosts
1st choice: ‘Preferred Owners’
VMs will start on preferred host
2nd choice: ‘Possible Owners’
VMs will start on a possible owner, only if a preferred owner is not available
If neither a preferred or possible owner is available, the VM will move to an active node, but not start
Also in Windows Server 2008 R2

20. Start VMs on Preferred Hosts
‘Persistent Mode’ will attempt to place VMs back on the last node they were hosted on during start
Only takes affect when complete cluster is started up
Prevents overloading the first nodes that startup with large numbers of VMs
Better VM distribution after cold start
Enabled by default for VM groups
Option is hidden from GUI in 2012+
Also in Windows Server 2008 R2

21. Keep VMs off the Same Host
AntiAffinityClassNames
Groups with same AACN try to avoid moving to same node
Configured by PowerShell directly on the cluster
System Center VMM has a GUI “Availability Groups”
Enables VM distribution across host nodes
Better utilization of host OS resources
Scenarios
Separate similar VMs
Guest cluster nodes
DCs or infrastructure servers
Separate tenets
For affinity, use preferred owners
Also in Windows Server 2008 R2

22. Optimize a Clustered Virtual Machine
