Below are three possible scenarios in which multiple replication targets are configured.
All Shares or Partitions Replicate to Multiple Targets
For enhanced disaster recovery, all shares or partitions on the DXi6900 are configured to replicate to
multiple targets. In this scenario, even if one target system is lost, the other target system still retains a full
copy of all data on the source DXi6900.
Some Shares or Partitions Replicate to Multiple Targets
For increased flexibility, each share or partition on the DXi6900 is configured to replicate only to the targets
where needed. In this scenario, shares or partitions fall into three categories:
Some shares or partitions replicate to Target 1. (They may also replicate to Target 2.)
l
Some shares or partitions replicate to Target 2. (They may also replicate to Target 1.)
l
Some shares or partitions are not replicated.
