Performance Topology with Switches
Previous topologies use Fibre Channel HUBs for interconnecting the arrays with the hosts.
In these topologies there is basically one loop with all devices connected to it. The disk
array FC60 can be connected to switches. Connecting the array using switches provides for
increased performance. Two switch topologies are provided in
Figure 42 and Figure 43 .
Note
Hubs and switches should not be mixed in these array topologies. All devices
must be directly connected to a switch.
Switches require firmware version V.6C2 to support the disk array FC60
