Tight integration enables storage-based
replication
System Storage solutions support Site Recovery Manager with
individual software modules, called Storage Replication Adaptors
(SRAs), along with the storage-based replication and snapshot
capabilities available with the systems. Developed and supported
by IBM, the Storage Replication Adaptors use the Storage
Networking Industry Association (SNIA) SMI-S interface
to provide the connection to the storage array. For easy
access, the SRAs are made available for distribution by
VMware and can be found on the vCenter Site Recovery
Manager product download website. This tight integration
between Site Recovery Manager and System Storage solutions
