  1. Understanding Hyper-V Replica: Performance, Networking and Automation Raghavendran Gururajan Charles Joy MDC-B373

  2. http://ucp.totfarm.com/pics/pic_12073492466573.jpg http://www.microsoft.com/casestudies/Case_Study_Detail.aspx?casestudyid=710000001728

  3. Session Objectives and Takeaways • Overview of Hyper-V Replica • Infrastructure Planning • Deployment Considerations and Automation • What’s new in Windows Server 2012 R2

  4. Hyper-V Replica - Windows Server 2012 DR Scenarios Inbox Replication Application Agnostic Storage Agnostic Affordable Flexible Simple

  5. Deployment Scenarios Hoster’s Data Center DR as a Service Replication between two data centers Customer 2 Customer 1

  6. Infrastructure Planning

  7. Infrastructure Planning • Customer Asks: • How much network bandwidth is required? • How much storage is required? • Is my IOPS provisioning sufficient? • Does Hyper-V Replica impact CPU, Memory?

  8. Demo Capacity Planning Download the Capacity Planner from http://www.microsoft.com/en- us/download/details.aspx?id=39057

  9. Storage

  10. Storage IOPS

  11. Network

  12. Network Throttling • How do I use specific bandwidth for replica traffic? • Use Windows Server 2012 QoS to throttle replication traffic • Throttling based on the destination subnet New-NetQosPolicy “Replication Traffic to 10.0.0.0/8” –DestinationAddress 10.0.0.0/8 –MinBandwidthWeightAction 40 • Throttling based on the destination port New-NetQosPolicy “Replication Traffic to 8080” –DestinationPort 8080 –ThrottleRateActionBitsPerSecond 100000

  13. Demo Network Throttling

  14. Network Compression Compression on by default WAN optimizers on top of built-in compression • Whitepaper available at http://www.microsoft.com/en-us/download/details.aspx?id=36786

  15. Deployment

  16. Deployment Considerations • How do I transfer the initial VHDs? • Online Initial Replication • Out of band – Export and Import IR package • Backup/Restore with Resync • Where do I place the replica VHDs? • Default storage location • Storage migrate to custom location before IR • Backup/Restore

  17. Deployment Considerations • How should I monitor replication? • Replication Health and State • Last Synchronized Time • Average Replication Latency • Perfmon counters and Event logs

  18. Deployment Considerations • How are replication failures handled? • Network disconnects - Automatic retry and resume semantics • Out of sync - Resynchronization

  19. Deployment Considerations What happens when VMs migrate? • Migration of primary VMs • Live migration and storage migration of logs • Replication resumes post migration of VMs • Migration of replica VMs • Primary server authorization What is my backup strategy? • Backup from Hyper-V Primary Server

  20. Guest Dependencies What’s running in the guest? • Hyper-V support matrix including Linux • Guest IP injection • http://technet.microsoft.com/library/hh831531.aspx • Support for Virtualized AD • Recommended: AD with WS 2012 • Support for SQL workloads • Required: EnableWriteOrderPreservationAcrossDisks

  21. Failover Considerations Failover Actions (Test/Planned/Unplanned) • Failover to latest or older point in time • Static IP injection or DHCP or Network virtualization • Failback • Split brain scenarios

  22. Demo Charles Joy Runbook Execution – Hyper-V Replica Orchestrated Planned Failover (and Failback)

  23. Windows Server 2012 R2

  24. Hyper-V Recovery Manager (HRM) DR Journey

  25. Windows Azure Hyper-V Recovery Manager (HRM) Overview Hyper-V Recovery Service DR Orchestration DR Orchestration SCVMM SCVMM DRP DRP Extensible Data Channel (Hyper-V Replica) Compute Compute Storage Storage Networks Networks Primary Site Secondary Site

  26. What’s new in Windows Server 2012 R2 Extended Replication 30 Sec Replication Linux VM Enhancements Seamless Upgrade

  27. Demo 30 Seconds Replication Frequency

  28. Demo Extended Replication

  29. Positioning – What Hyper-V Replica isn’t?
