Dell PowerVault MD Series Storage Arrays Storage Replication Adapter (SRA) Best Practices Guide (Client)

SRA supports up to four Remote Replication groups per storage array. All protected Datastores must reside in one of the four groups. Because a Remote Replication group is treated as a single entity, any action affecting the group (for example, swapping roles) affects all virtual disks in the group.

If cross-replication of Datastores is required (for example, replicating from the recovery site to protected site), the Datastore virtual disks for the recovery site must be contained in a separate Remote Replication group than the virtual disks on the protected site.
