Virtual Machine Monitoring
• Upon service failure, Service Control Manager inside guest will attempt to restart the service
• After 3 failures, Cluster Service willtrigger event log entry 1250
• VM State = Application in VM Critical
• VM can be automatically restarted on the same node
• Upon subsequent failure, VM can be failed over and restarted on alternative node
• Extensible by Partners

Hyper-V cluster with VMs on each nodeUpon failover, VMs restart in priority order
Failover Priority, Affinity & Anti-Affinity
• Failover Priority ensures certain VMsstart before others on the cluster
• Affinity rules allow VMs to reside oncertain hosts in the cluster
• AntiAffinityClassNames helps to keep virtual machines apart on separate physical cluster nodes
• AntiAffinityClassNames exposedthrough VMM as Availability Set
Ensure Optimal VM Placement and Restart Operations

Anti-Affinity keeps related VMs apart
Cluster Aware Updating
• Reduces server downtime and user disruption by orchestration of cluster node updates
• Maintains service availability without impacting cluster quorum
• Detects required updates and moves workloads off nodes for updates
• Uses Windows Update Agent or extensible plug-in

Guest Clustering
• Full support for running clustered workloads on Hyper-V host cluster
• Guest Clusters that require shared storage can utilize software iSCSI, Virtual FC or SMB
• Full support for Live Migration of Guest Cluster Nodes
• Full Support for Dynamic Memory of Guest Cluster Nodes
• Restart Priority, Possible & Preferred Ownership, & AntiAffinityClassNameshelp ensure optimal operation

Guest Clustering with Shared VHDX
• VHDX files can be presented to multiple VMs simultaneously, as shared storage
• VM sees shared virtual SAS disk
• Unrestricted number of VMs canconnect to a shared VHDX file
• Utilizes SCSI-persistent reservations
• VHDX can reside on a Cluster Shared Volume on block storage, or onFile-based storage
• Supports both Dynamic and Fixed VHDX

Streamlined Incremental Backup
• Allows incremental backup of virtual hard disks
• Is Volume Shadow Copy Service (VSS)-aware
• Backs up the Hyper‑V environment
• Requires no backup agent inside virtual machines
• Saves network bandwidth
• Reduces backup sizes
• Saves disk space
• Lowers backup cost

Once Hyper-V Replica is enabled, VMs begin replication
• Affordable in-box business continuity and disaster recovery
• Configurable replication frequencies of 30 seconds, 5 minutes and 15 minutes
• Secure replication across network• Agnostic of hardware on either site• No need for other virtual machine
replication technologies• Automatic handling of live migration• Simple configuration and
management

Hyper-V Replica | Extended Replication
• Once a VM has been successfully replicated to the replica site, replicacan be replicated to a 3rd location
• Chained Replication
• Extended Replica contents match the original replication contents
• Extended Replica replication frequencies can differ from original replica
• Useful for scenarios such as SMB -> Service Provider -> Service Provider DR Site
Replicate to 3rd Location for Extra Level of Resiliency

Replication can be enabled on the 1st replica to a 3rd site

Hyper-V Recovery Manager
• Protect important services bycoordinating replication and recovery of VMM-managed private clouds
• Automates replication of VMs within clouds between sites
• Hyper-V Replica provides replication, orchestrated by Hyper-V Recovery Manager
• Can be used for planned, unplanned and testing failover between sites
• Integrate with scripts for customization of recovery plans
Orchestrate protection and recovery of private clouds
