SRDF is used our disaster recovery service by using replication from our production site to our DR site. We have two different production and DR site pairs in two different global geographies. One use case has got SRDF asynchronous replication and another has SRDF synchronous replication primarily due to business requirements and the location of the DR sites. At the DR sites, snapshots of replicated volumes are created and provisioned to hosts facilitating periodic DR tests.

We primarily use the solution for its high availability.
