RemoteDataReplication/DisasterRecovery
RemoteDataReplication/DisasterRecovery/DisasterRecovery (RDR/DR) guarantees write-order integrity across a group of LUNs during replication. It is useful for databases or clusters that use multiple volumes for data that is related or dependent on each other. This avoids data loss and provides faster application availability.

RDR/DR provides the following functions:
Multi-LUN replication order consistency
Replicas of an "Atomic Group" of LUNs have data written in the same timestamp order as the original group (across the group, not just a single LUN).
All modes supported
Synchronous, semi-synchronous (asynchronous, all data sent), and background-copy (asynchronous, all data sent - priority adjustable) modes supported. Change the replication mode non-disruptively.
