Hyper-V Live Migration<br />Move a running VM between hosts with no user-perceived downtime<br />Client is not aware of the migration<br />Maintain open TCP connections to the guest OS<br />Clients stay connected<br />Planned failover<br />Failover Clustering still recovers VM from a disk in an unplanned failover<br />
  • 22. The Dynamic Datacenter Vision<br />
  • 23. Live Migration<br />Memory content is copied to new server<br />Live Migrate<br />SAN<br /><ul><li>May be additional incremental data copies until data on both nodes until essentially identical
  • 24. Entire VM memory copied</li></ul>VHD<br />
  • 25. Live Migration<br />Client directed to new host<br />SAN<br /><ul><li>Session state is maintained
  • 26. No reconnections necessary
  • 27. Clients stay connected to “live” VM
  • 28. ARP issued to point routing devices to new node
  • 29. Old VM deleted after success</li></ul>VHD<br />
  • 30. Failover Clustering Today<br />Failover Clustering has implemented a “shared nothing” storage model for the last decade<br />Placing VHDs on same volume requires that VMs run on same host cluster node<br />Only one node accesses a LUN at a time<br />SAN<br />SAN<br />
