Replication pairs

A replication pair is a pair of volumes with one volume at the source system and one at the target system. The data from the source volume is replicated to the target volume.

The replication consistency group can contain several replication pairs. A volume can be a member of at most one replication pair. When the replication pair is created, both the source volume and the target volume must be the same size. It is recommended, but not mandatory, that the volumes in the replication pair have the same attributes (including zero padding and granularity), not doing so can impact performance and capacity.
