Replication
Replication function will help users to replicate data easily through LAN or WAN from
one IP SAN storage to another.
The procedures of Replication are on the following:
1.
Copy all data from source VD to target VD at the beginning (full copy).
2.
Use Snapshot technology to perform the incremental copy afterwards. Please be fully
aware that the incremental copy needs to use snapshot to compare the data difference.
Therefore, the enough snapshot space for VD clone is very important.
Setup the Replication port on the source IP SAN storage
The Replication uses the last iSCSI port on the controller to replicate the data. That is
the forth iSCSI port on DSN-6110/ 6120. When the iSCSI is configured as Replication
port, it is no longer available for the host to connected as iSCSI port until it is configured
as the normal iSCSI port again.
1.
In the operation menu of the last iSCSI port on the controller, select “Enable
Replication” to set this port as the Replication port. The last iSCSI port on
controller 2 will also be set as the Replication port automatically at the same time.

The setting can be reverted by selecting “Disable Replication” in the menu.
