Hyper-V in Windows Server 2012 includes a new capability called “Hyper-V Replica”. Hyper-V Replica allows administrators to replicate their virtual machines from a primary server/cluster to a replica server/cluster.  I have been asked many times , how much bandwidth we need for the Hyper-V replica.

And I usually gave a typical consultant answer:  It depends Smile    …  which is true, but not satisfying.

 

The Capacity Planner for Hyper-V Replica guides the IT administrator to design the server, storage and network infrastructure which is required to successfully deploy Hyper-V Replica.

would be good to get some feedback from you on real life scenarios and how accurate the planning tool is
