  5. 5. History of Hyper-V VM MigrationsWindows 2008 Windows 2008 Windows 2012 R2 • Quick • Live • Shared Migration Migration Nothing Live • Quick Migration Storage • SMB Live Migration Migration Hyper-V Failover • Live Storage Cluster – 1 LUN Hyper-V Failover Migration per VM (drive Cluster – Cluster letters) Hyper-V Shared Volumes Failover Cluster (CSV) – CSV 2.0 5
  6. 6. VM and Storage Mobility Migration optionsLive Migration with Shared SMB share based Live Share nothing Live Migration Storage Migration Live Virtual Machine and Live Storage Migration Storage Migration (VSM) There are so many more migration options available in Windows 2012. 6
  7. 7. Test your understanding… Scenario Is the VM mobile? If YES, what is the Is my VM highly Migration Method? available?

Within the technical capabilities of the networking hardware2. Live Storage Migration (Storage vMotion) is available in Enterprise & Enterprise Plus editions of vSphere 5.03. Shared Nothing Live Migration will be available in vSphere 5.1 9
  10. 10. Hyper-V ReplicaNew feature• Replicates Hyper-V virtual machines from a primary to a Replica siteBenefits• Affordable in-box business continuity and disaster recovery solution• Failure recovery in minutes• More secure replication across network• No need for storage arrays• No need for other software replication technologies• Automatic handling of live migration• Simpler configuration and management 10
  11. 11. Hyper-V Replica Deployment ScenariosDeployment Use Cases1. Head office to Remote branch office or vice versa2. Hoster - DR service for customers - Company data center to Hoster data center 11
  12. 12. Hyper-V Replica complements Array Based ReplicationReplication Replication Cost Management Performance Method Provider • Continuous • Flexible Storage Asynchronous • VM Granularity Options Available Replication • Open APIs provide • Unlimited VM • RPO - 5-15 mins extensibility, Hyper-V Microsoft Replication included • RTO - 10-30 mins interoperability and Replica • Feature included with • Application Level prevent vendor the Windows Server Consistency lock-in 2012 license • File Level Consistency NetApp, HP, Fujitsu, • High end replicating IBM, HDS, FalconStor, storage • LUN-VM Layout • SynchronousStorage Based 3Par, EMC, LSI, • Additional replication • Coordination with Replication Replication Compellent, EqualLogic software storage team • High Data Volumes and more… • $$$$$
  13. 13. Hyper-V Replica – Test Failover Site A Site B• Non-disruptive testing of workload – zero downtime• Test any recovery point• Pre-configure isolated network
  14. 14. Hyper-V Replica – Planned Failover 1. Shutdown primary Site B 2. Send last delta Site A 3. Failover to replica 4. Reverse replication• Testing DR or failover before disaster or planned maintenance• Zero data loss but some downtime• Efficient reverse replication
  15. 15. Hyper-V Replica – Unplanned Failover Site A Site B • Only available if primary site is unresponsive• Minor data loss• No reverse replication – Can be manually configured later
  16. 16. Hyper-V Replica – Replication with VM Mobility Site A Site B• Seamless VM migration on primary• Migration of replica VM is also supported• Works with live migration, storage and quick migration

  20. 20. SMB Transparent Failover• Failover transparent to server application • Zero downtime – small IO delay during failover• Supports planned and unplanned failovers • HW/SW Maintenance Hyper-V • HW/SW Failures • Load Rebalancing• Resilient for both file and directory fs1share fs1share operations• Requires: File Server File Server • Windows Failover Clusters Node A Node B • Both server running application and file server File Server Cluster cluster must be Windows Server 2012 • Shares enabled for ‘continuous availability’
  21. 21. SMB Scale-Out File Server• Targeted for server app storage Hyper-V Cluster (Up to 64 nodes) • Example: Hyper-V and SQL Server • Increase available bandwidth by adding cluster nodes• Key capabilities: Data Center Network • Active/Active file shares (Ethernet, InfiniBand or combination) • Fault tolerance with zero downtime File Server Cluster • Fast failure recovery (Up to 4 nodes) • Transparent CHKDSK Single Logical File Server (FSShare) • Support for app consistent snapshots Single File System Namespace • Support for RDMA enabled networks Cluster Shared Volumes • Optimization for server apps • Simple management
  22. 22. VSS for SMB File Shares• Application consistent shadow Read from Backup Server copies for server application data Shadow Copy Share stored on Windows Server 2012 G file shares A Backup File Share Shadow Copy Agent• Backup and restore scenarios Backup Agent E Request Shadow Copy B Coordinate Shadow Volume Shadow Copy Service Copy D• Full integration with VSS Volume Shadow Copy Service Relay Create Shadow Copy F Shadow infrastructure Create Shadow Copy C Copy VSS Providers request File Share Shadow Copy Provider fsfoo fsfoo@t1 Data volume Shadow Copy Hyper-V Host Server File Server
