Intracluster Hyper-v Replica RRS feed

  • Question

  • I have a 2 node hyperv 2012R2 cluster which is replicating VM from another cluster

    On this cluster we're running a virtual machine which is not clustered , because must be running on SSD local disks , that we'd like to "replicate" to the second node ( which has local SSD too ) .

    Is there a way of doing this ?

    thanks

  • Intra-cluster replica is not possible. If Hyper-V detects that it is running on a cluster node, it will not participate directly in replica. It will require that you use the Replica Broker. The Replica Broker cannot replicate with itself.

    You will need to facilitate this with another mechanism, such as backup, a scheduled export, or a third-party replication utility.

  • Seems like a perfect case for the solutions like hpe vsa (the first place that comes to mind, but you just google for alternatives). All I would observe is that you have to acquire at least 10 gbe networking to squeeze out maximum performance from your SSDs.

  • Eric is totally correct. I would recommend you using a 3rd party tool to create a mirrored storage pool for this case between two hosts. This approach (unlike Hyper-V replica) will give you the ability to make your virtual machine not only replicated but highly-available which means it will automatically failover to another host in case of failure. HPE VSA https://www.hpe.com/emea_europe/en/storage/storevirtual.html or StarWind Free https://www.starwindsoftware.com/starwind-virtual-san-free will do the job.
