Cluster Installation
Bidirectional Solution
You may configure data replication groups to replicate data from storage system A to
storage system B and other unrelated data replication groups to replicate data from
storage system B back to storage system A. This feature, called bidirectional
replication, allows for a storage system to have both source and destination virtual
disks, where these Vdisks belong to separate Data Replication (DR) groups. This
setup has no effect on normal operation or failover policy and has the advantage of
allowing for the destination storage system to be actively used while also providing a
disaster-tolerant copy of the other site’s data. If the business needs require
bidirectional data transfers, you must determine the effect on the links.
Follow the steps in this chapter to replicate data from storage system B back to A.
