Does Hyper-V replication support the replication of memory, or is it just the deltas between disk writes? ie, in a fail over situation would a server with a memory fault have this same memory fault replicated?

  • `1.` Everything I've ever read about it states that Hyper-V Replica replicates the VHD(X) of the VM, not it's state (memory). `2.` Replication does **not** occur in real time. `3.` There's no automatic failover. – joeqwerty May 11 '15 at 15:18

No, it is just a live storage replication. Replication occurs asynchronously, periodically. Automatic failover would be created via script. See http://blogs.technet.com/b/keithmayer/archive/2012/10/05/automate-disaster-recovery-plan-with-windows-server-2012-hyper-v-replica-and-powershell-3-0.aspx as an example. Typically replica is used for DR, and failover clustering at the application level for application fault tolerance.

  • Thanks, that makes sense. Just wasn't sure if it provided some really deep level of live replication. – Nattrass May 11 '15 at 17:14
