User Manual
6.11 QReplica (Optional)
QReplica function will help users to replicate data easily through LAN or WAN from one
subsystem to another.
The procedures of QReplica 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.
Activate the license key
User needs to obtain a license key and download it to the RAID subsystem to activate
the QReplica function. Each license key is unique and dedicated to a specific subsystem.
It means that the license key for subsystem A cannot be used on another subsystem. To
obtain the license key, please contact sales for assistance.
Setup the QReplica port on the source subsystem
The QReplica uses the last iSCSI port on the controller to replicate the data. The iSCSI
is configured as QReplica 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
QRepica” to set this port as the QReplica port. The last iSCSI port on controller 2
will also be set as the QReplica port automatically at the same time.
