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.
Hyper-V administrators of Windows Server 2012 and Windows Server 2012 R2 can replicate their virtual machines from a primary server / cluster to a replica server / cluster for business continuity and disaster recovery purposes. The Capacity Planner for Hyper-V Replica provides server, storage and network provisioning guidance which would allow IT administrators to successfully plan for a Hyper-V Replica deployment

The Setup is real easy and a comprehensive report is prepared that shows CPU, RAM, Disk and Network capacity needed to successfully support your specific configuration and environment.

First we choose a time to collect utilization metrics for the Vm’s to replicate. best way to test this is during work hours and 30 minutes or longer.
10 hyper-v server can be selected in one Run.

If you use a Cluster use the Broker and not the Hyper-v FQDN.

And If a server is not enabled for replication you will see this error. and you can run this with or without Certificates.


You can only pick VM’s that are not Replica Enabled and if the VM holds more Disk you can unselect the disk.
After running this there will be a HTML report with all the metrics CPU,Memory,IOPS,Storage usage, network throughput.
This way you get insight information on what can I expect when using hyper-v replica

How many IOPS do I need and gives you the optimal setting

The Network info is great info What do I need and how many is consumed during the Replica.
And read the documentation there is a lot of useful info in this document and this will help you to understand the report.
