). 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
).
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:
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:

Task Overview
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
).
