Group Administration Volume replication

Reciprocal replication between partners
Both partners replicate volumes to each other. For example, in Figure 12-3, GroupA replicates Volume1 to
GroupB, and GroupB replicates Volume2 to GroupA. For the replication of Volume1, GroupA i
s the primary
group, and GroupB is the secondary group. For the replication of Volume2, GroupB is the primary group, and
GroupA is the secondary group.

Centralized replication
Multiple partners replicate volumes to another partner. For example, in Figure 12-4, GroupA and GroupB replicate
volumes to Group C. In this configuration, GroupA and GroupB are primary groups, and GroupC is the secondary
grou
p.
