Infrastructure Planning

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?

Capacity Planning

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

Storage IOPS

Network

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

Demo

Network Throttling

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

Deployment

• 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

• How should I monitor replication?• Replication Health and State• Last Synchronized Time• Average Replication Latency• Perfmon counters and Event

logs

Deployment Considerations

• How are replication failures handled?• Network disconnects -

Automatic retry and resume semantics

• Out of sync - Resynchronization

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

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

Positioning – What Hyper-V Replica isn’t?Solution Use Cases Replica PositionSAN Replication

• High availability with zero data loss • DR for Virtualized workloads

• 30 Sec – 15 minLive Migration • Load balancing

• Server Patching• Multi site • Complements

Storage Migration

• Storage out of space• Storage upgrade

• Ongoing Replication• Complements

Guest Clustering

• Guest application patching• Guest application failure

• Not compatible

Backup solutions

• Data recovery• Archival for compliance, auditing

• Disaster Recovery only

System Center + HRM

• Manage @ Scale • Platform component of Enterprise DR
