APPENDIX C
Configuring Replication
This appendix describes replication, provides reference information, and a
procedure for configuring the network interfaces to support replication in a 7700
FSP storage cluster.
Configuring Network Interfaces for Replication
In a 7700 FSP storage cluster, if you are using the replication feature, it is
performed over TCP using the two 10Gpbs ports in HBA slot 1 of the rear chassis
in the 7700 FSP Controllers.
The replication interface port is named
rep0
at HBA slot 1-0 and port
rep1
at HBA
slot 1-1. Currently, replication configurations only support using
rep0
.
Replication Overview
Replication is configured on a per-LUN basis and this is unidirectional from the
primary LUN to the replica 7700 FSP Controller to an existing storage pool and a
new or existing LUN. A 7700 FSP Controller that is primary for one replication LUN
may also be a replica for another 7700 FSP Controller’s LUN.
