Multiple Servers/Two Switches/Two Locations
Virtual Local Area Network (VLAN) and zoning can be employed to provide separate networks for iSCSI
and FC, respectively. Whether using a single switch or multiple switches for a particular interface, you can
create a VLAN or zone for I/O and a VLAN or zone for replication to isolate I/O traffic from replication traffic.
Since each switch would include both VLANs or zones, the configuration would function as multiple
networks.
This section provides information on the rear panel of two RAID chassis with I/O and replication occurring on
different networks.
