I've had a little interview with Gabrie van Zanten (Gabes Virtual World) about two new upcoming Storage Replication Adapters. Site recovery Manager communicates with storage arrays trough storage replication adapters (or SRAs). Storage replication adapters translate generic commands generated by SRM for tasks such as discovering arrays in the datacenter determining which LUNs are replicated by the arrays. SRAs also assist in initiating recovery plan tests and failovers.
