  1. 1. Didier Van Hoye - Technical Architect Microsoft MVP & MEET Member http://workinghardinit.wordpress.com @workinghardinit
  2. 2. Live Migrate VM and Storage to Clusters Live Migrate VM and Storage Between Clusters Live Migrate VM and Storage to Stand-Alone Server You can move a VM anywhere in your datacenter with zero downtime!
  3. 3. Client accessing VM Live Migrate this VM to another physical machine VHDX
  4. 4. Memory content is copied to new server VM pre-staged VHDX
  5. 5. Pages are being dirtied Client continues accessing VM VHDX
  6. 6. Smaller set of changes Recopy of changes VHDX
  7. 7. Partition State copied VM Paused VHDX
  8. 8. Old VM deleted once migration is verified successful Client directed to new host VHDX
  9. 9. • Windows Server 2012 now supports the ability to do multiple live migrations in parallel • Unlimited number of live migrations can be performed in parallel • Default configuration of 2 simultaneous LM’s per host • Wield this power wisely • Excessive number of simultaneous migrations may actually result in overall longer times than serially
  10. 10. • • • • •
  11. 11. Update Coordinator Admin Initiate Cluster-Aware Updating
  12. 12. Storage Migrate this VHDX to another disk Client accessing VM VM stays running servicing clients VHDX
  13. 13. New VHDX created on new storage VHDXVHDX
  14. 14. Writes mirrored to new Destination VHDX Reads are from Source VHDX VHDX VHDX
  15. 15. VHDX data copied from Source to Destination VHDXVHDX
  16. 16. Reads and Writes transitioned to new VHDX VHDX
  17. 17. • Protects from unplanned downtime: • Hardware • Host OS • VM • Guest OS • Apps in VMs
  18. 18. NetFT Node 1 ClusSvc VMMS User Mode Kernel Mode RHS Guest OS VDev NetFT Node 2 ClusSvc VMMS RHS Guest OS VDev vmclusres.dllvmclusres.dll
  19. 19. FC SAS RBOD iSCSI FCoE SAS JBOD Shared Storage RAID HBA Software Replication Hardware Replication SMB Data Replication Application Replication Spaces
  20. 20. VM running on Node 2 is unaffected Coordination Node SAN Connectivity Failure I/O Redirected via network VM’s can then be live migrated to another node with zero client downtime VHDX
  21. 21. Cluster
  22. 22. CLUSTER CLUSTERiSCSI or FC Guest Cluster SAN SAN
  23. 23. VHDX VHDX
  24. 24. • Automatic and manual failover for DR • Supports 3rd party hardware and software based replication
  25. 25. Hyper-V Replica • RPO = 5 minutes • RTO = Manual (longer) • Cost = In-box in Windows Server • Complexity = Low Multi-Site Clustering • RPO = 0 minutes* • RTO = Automatic (fast) • Cost = High • Complexity = High *depending on 3rd party replication solution
  26. 26. Systems in lock step
  27. 27. Planned Downtime Unplanned Downtime Disaster Recovery
