Hyper-V Replica Capacity Planner

Hyper-V Replica Capacity Planner

Customers have frequently asked us for capacity planning guidance before deploying Hyper-V Replica – e.g.: “How much network bandwidth is required between the primary and replica site”, “How much storage is required on the primary and replica site”, “What is the storage impact by enabling multiple recovery points” etc.

The answer to the above and many other capacity planning questions is “It depends” – it depends on the workload, it depends on the IOPS headroom, it depends on the available storage etc. While one can monitor every single perfmon counter to make an informed decision, it is sometimes easier to have a readymade tool.

The Capacity Planner for Hyper-V Replica which was released on 5/22, allows you to plan your Hyper-V Replica deployment based on the workload, storage, network and server characteristics. The guidance is based on results gathered through our internal testing across different workloads.

You can download the tool and it’s documentation from here - http://www.microsoft.com/en-us/download/details.aspx?id=39057

Instructions:

1) Download the tool (exe) and documentation

2) Read the documentation first and then try out the tool. You should familiarize yourself with some nuances listed in the documentation before using the tool.

So go ahead, use the tool in your virtual infrastructure and share your feedback and questions through this blog post or in the community forum. We would love to hear your comments!

  • This should be helpful for one of my upcoming customer proof of concepts.  This customer will likely be going the 2012 R2 route in six to nine months.  Hyper-V replica is a big consideration for them as they are trying to streamline support and have fewer critical software vendors blaming each other for the problem of the day.

  • Thanks for this tool, although unfortunately I am not able to get it to work. I cant get it to accept my certificate for some reason. When i click to add the cert i get the error ending "Install a valid certificate and try again"

    This certificate works fine for the actual replication though so I dont see where the problem is.

    Thanks

  • Rob - Can you help me understand the setup? How many primary servers, replica servers are there in your deployment? Where is the tool being run from (primary or replica or from some other server?)

    Regards

  • It would be nice if you could run this tool on Hyper-V 2012 servers!

  • Hi we find this a very useful tool
