targets (see Adding a Replication Target on page 270). Then, for each share or partition, select which
targets to replicate data to—one, both, or neither (see Enabling Replication For a Share or Partition on page
140).
Below are three possible scenarios in which multiple replication targets are configured.
AllSharesorPartitionsReplicatetoMultipleTargets
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.
SomeShares orPartitionsReplicatetoMultipleTargets
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:
l 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.
Performing Data Replication
The Replication page allows you to set up replication for NAS shares or VTL partitions and to replicate and
recover data.
To access the Replication page, click the Replication menu.
The Replication page contains the following tabs:
l Replication Send on page 137
l Receive NAS on page 145
l Receive VTL on page 155
l Actions on page 165
l Reports on page 168
TaskOverview
Use the DXi6900 data replication features to perform the following tasks:
l Replicate all data on a share or partition to another system where it can be recovered at a later time
(see Task Overview: Setting Up and Performing Replication on the next page).
l Automatically replicate files or cartridges to another system where they are immediately available
(see Task Overview: Setting Up and Performing Directory/File or Cartridge Based Replication on
page 135Task Overview: Setting Up and Performing Directory/File or Cartridge Based Replication on
page 135).
