SRM 5.1 & NetApp - VM with RDM and MSCS

Hello,

I'm implementing SRM 5.1 with NetApp (With SnapMirror) and I have several questions:

- Replication of volumes through the array manager, run correctly

- How do the replication of virtual machines with RDM? can also be done through array manager (with SnapMirror) or better do it with vSphere Replication. Can be performed by vSphere Replication?

- Do any advice for replication of virtual machines in a cluster of Microsoft?

thanks for all!
