When you use array-based replication, one or more storage arrays at the protected site replicate data to peer arrays at the recovery site. With storage replication adapters (SRAs), you can integrate Site Recovery Manager with a wide variety of arrays.

To use array-based replication with Site Recovery Manager, you must configure replication first before you can configure Site Recovery Manager to use it.

Storage replication adapters are not part of a Site Recovery Manager release. Your array vendor develops and supports them. You must install an SRA specific to each array that you use with Site Recovery Manager on the Site Recovery Manager Server host. Site Recovery Manager supports the use of multiple SRAs.
