Hello everyone,
I'm trying to understand how Windows Storage Replica works in cluster-to-cluster mode.
Here’s the context:
We already have a cluster with replication in place using Hyper-V Replica Failover. However, this setup has limitations. Specifically, it doesn't allow us to choose the destination volume, which forces us to create a large CSV (Cluster Shared Volume) in the cluster. Microsoft advises against creating excessively large CSVs, so we want to avoid replicating the same system and its associated failover approach.
Now, we're exploring the possibility of using Storage Replica, but the process isn't entirely clear to me.
I've already tried using PowerShell commands and can see the storage replication in Windows Admin Center. Here’s the command I used:
New-SRPartnership -SourceComputerName "myfirstcluster" `
-SourceVolumeName "C:\ClusterStorage\mystorage" `
-SourceLogVolumeName "\\?\Volume{e4637062-a9dd-49a5-83d0-6cbf8d664816}" `
-DestinationComputerName "mysecondcluster" `
-DestinationVolumeName "C:\ClusterStorage\mysecondstorage" `
-DestinationLogVolumeName "\\?\Volume{5ad1b414-9e85-4f66-8b78-bfa825370d48}" `
-ReplicationMode Synchronous `
-Verbose
From what I understand, Storage Replica doesn’t behave like Hyper-V Replica in terms of replicating VM objects to the second cluster. It seems to only handle the replication of raw storage (essentially a copy-paste of volumes) without managing VM-specific elements.
Can anyone confirm if this interpretation is correct? Or is there a way to make Storage Replica handle VM objects across clusters?
Thanks for your insights!
