Hyper-V Optimization with Failover Clustering

Client accessing VM VHD Quick Migrate 1.Save state of VM 2.Offline VM & cluster resources 3.Move VM & cluster resources 4.Online Cluster Resources 5.Start VM 6.Client reconnects

Data over any network VHD Coordinator Node 1 LUN : Many VMs Hyper-V Only in 2008 R2 Hyper-V Only in 2008 R2 Every node can access storage

Memory content is copied to new server Live Migrate May be additional incremental data copies until data on both nodes is essentially identical VHD

ARP redirects clients to new node Old VM deleted after success Client directed to new host

Branch Office VHD Storage Live Migration: Moves VHDs from one disk to another, supports concurrent LMs Storage Live Migration: Moves VHDs from one disk to another, supports concurrent LMs Hyper-V Replica: Point-in-time replication of VHDs for disaster recovery VHD Network Live Migration: Moves VMs across the network, supports concurrent LMs “Shared Nothing” Live Migration: Moves VMs & VHDs across the network & SAN, supports concurrent LMs

Draining a node Node is paused preventing new groups from moving to that node All groups are issued a move VMs are queued up and live migrated off based on priority Resuming a node Resume-ClusterNode –Failback invokes failback policies to return groups to that node when it is brought out of Maintenance Mode
