Dual FC ports, dual FC switches, single FC fabric
This example uses multipath I/O to eliminate single points of failure. The fabric

first FC port connects to the first FC switch and the second FC port connects to the
second FC switch. The cluster also includes two RAID arrays containing multiported
disks.
