Step-by-step: Planning RPO and WAN Bandwidth for Hyper-V Replica in Windows Server 2012

Windows Server 2012 and the FREE Hyper-V Server 2012 include Hyper-V Replica as a new disaster recovery feature for site-level outages.  Hyper-V Replica provides asynchronous host-to-host replication between sites for Virtual Machines.

For more details on implementing and automating disaster recovery with Hyper-V Replica, please see my prior post on this topic HERE.

Planning Network Bandwidth for Hyper-V Replica

By using asynchronous replication across a standard IP network connection between sites, Hyper-V Replica can provide a very quick (within seconds or minutes) Recovery Time Objective ( RTO ).  However, when discussing disaster recovery with IT Pros, often times the conversation turns to planning for network bandwidth between sites to meet Recovery Point Objectives ( RPO ).  My friend and colleague, Tommy Patterson, has authored a great step-by-step article and a planning tool on his "virtuallycloud9" blog as guidance for determining network bandwidth requirements when using Hyper-V Replica.

Tommy's article covers:

  • Defining Realistic Disaster Recovery Expectations
  • Bandwidth Considerations
  • Practical Implementations
  • Bandwidth Restrictions and Optimization
