Dell MD Storage Array vCenter Plug-in | 25
This example shows a fully redundant fabric configuration. If an FC switch or HBA fails,
alternate switch still connects to both storage controllers in the storage array. If a storage controller also fails
, the ESX 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.
