• The primary group is congured as a replication partner.
• The correct amount of space is delegated to the primary group for storing replicas of primary group volumes. Increase that
space if necessary.
6. On the primary group, congure the volume for replication, specifying the appropriate replication space values, and verifying
the replication partnership.
7. On the primary group, replicate the volume.
8. (Optional) Set up a schedule to create replicas on a regular basis.
9. Monitor each replication operation and make sure it is successful.
If the replication operation is not successful, identify and correct the problem. For example, you might need to increase network
bandwidth or increase replication space.
10. Monitor the number of replicas and replication space usage over time. The goal is to keep a specic number of replicas without
wasting replication space.
• If replicas are deleted before you reach the number of replicas you want to keep, you might want to increase the replica
reserve percentage for the volume.
• If you are keeping an excessive number of replicas, you might want to decrease the replica reserve percentage for the
volume.
Replication to One Partner
One replication partner replicates volumes to another partner. For example, in Figure 15. Replication to One Partner, GroupA
replicates Volume1 and Volume2 to GroupB. GroupA is the primary group, and GroupB is the secondary group.

Replication to Multiple Partners
One replication partner replicates dierent volumes to dierent partners. For example, in Figure 16. Replication to Multiple Partners,
GroupA replicates Volume1 to GroupC, and GroupA replicates Volume2 to GroupB. GroupA is the primary group, and GroupB and
GroupC are secondary groups.
