This example shows a fully redundant fabric configuration. If a fibre channel switch or HBA fails, the alternate switch
still connects both storage controllers in the storage array. If a storage controller also fails, the host can still access the
remaining controller and all virtual disks fail over to that controller. A complete loss of access to storage occurs if any
other element fails.
