Infrastructure Planning
![Page 8: Understanding Hyper-V Replica: Performance, Networking and Automation](https://reader035.vdocument.in/reader035/viewer/2022081507/568161c9550346895dd1aebd/html5/thumbnails/8.jpg)
Infrastructure PlanningCustomer Asks:• How much network bandwidth is
required?• How much storage is required?• Is my IOPS provisioning sufficient?• Does Hyper-V Replica impact CPU,
Memory?
![Page 9: Understanding Hyper-V Replica: Performance, Networking and Automation](https://reader035.vdocument.in/reader035/viewer/2022081507/568161c9550346895dd1aebd/html5/thumbnails/9.jpg)

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 subnetNew-NetQosPolicy “Replication Traffic to 10.0.0.0/8” –DestinationAddress 10.0.0.0/8 –MinBandwidthWeightAction 40
• Throttling based on the destination portNew-NetQosPolicy “Replication Traffic to 8080” –DestinationPort 8080 –ThrottleRateActionBitsPerSecond 100000

Deployment
![Page 17: Understanding Hyper-V Replica: Performance, Networking and Automation](https://reader035.vdocument.in/reader035/viewer/2022081507/568161c9550346895dd1aebd/html5/thumbnails/17.jpg)
• 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
Deployment Considerations
![Page 18: Understanding Hyper-V Replica: Performance, Networking and Automation](https://reader035.vdocument.in/reader035/viewer/2022081507/568161c9550346895dd1aebd/html5/thumbnails/18.jpg)
• How should I monitor replication?• Replication Health and State• Last Synchronized Time• Average Replication Latency• Perfmon counters and Event
logs
Deployment Considerations
![Page 19: Understanding Hyper-V Replica: Performance, Networking and Automation](https://reader035.vdocument.in/reader035/viewer/2022081507/568161c9550346895dd1aebd/html5/thumbnails/19.jpg)
• How are replication failures handled?• Network disconnects -
Automatic retry and resume semantics
• Out of sync - Resynchronization
Deployment Considerations
![Page 20: Understanding Hyper-V Replica: Performance, Networking and Automation](https://reader035.vdocument.in/reader035/viewer/2022081507/568161c9550346895dd1aebd/html5/thumbnails/20.jpg)
• 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
Deployment Considerations

• 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
Guest Dependencies

• 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
Failover Considerations
