Single FC port, dual FC switches, single FC fabric
In this example, the fabric includes two FC switches managed by the cluster. Servers
13 are connected to the first FC switch; servers 46 are connected to the second
switch. The cluster also includes two RAID arrays, which contain multiported disks.
If a managed FC switch fails, the servers connected to the other switch will survive
and access to storage will be maintained.
