SRM & two-way recovery?

Does anyone know whether SRM will work in a two-way scenario?

EG. Site A has protected VMs that can be recovered on Site B AND Site B has protected VMs that can be recovered on Site A.

Clearly the underlying SAN needs to be able to replicate LUNs from A to B and from B to A.

Is there some document that says this works?

Site Recovery Manager supports configurations in which both sites are running active virtual machines that Site Recovery Manager can recover at the other site. Site Recovery Manager also supports active/passive sites in which Site Recovery Manager recovers virtual machines from a protected site at a recovery site that is not running other virtual machines during normal operation.

Users configure recovery plan workflows in one direction from Site 1 to Site 2 for the protected virtual machines in Site 1. Workflows are configured in the opposite direction from Site 2 to Site 1 for the protected virtual machines at Site 2.

Is this clear?

Hi

We can configure SRM for two-way replication as well as protection group and recovery plan but you need

Per CPU licnece for both sites.

you can have some best practices of SRM

Hi Jason,

Yes, you can have an Active - Active configuration as the other posters described.

Site A will have LUNs replicated to Site B and vice versa. All ESX hosts will be able to see both their Primary and Secondary (mirrored from the other site) LUNs. The SRA API will promote the Secondary LUNs to primary in the event of a failover being initiated.

Check out the Evaluation Guide. It's a really good walkthough:

You do this on both sites.
