the host server(s) from losing access to data in the event of a path failure since both RAID controller modules can independently access all the physical disks in the storage array.

SAN-Attached Cabling

SAN-attached cabling configurations provide the highest level of redundancy and alternate-path connectivity between the host server and storage array. A SAN configuration using a Fibre Channel compatible switch fabric allows you to establish multiple redundant paths to data on the storage array.

NOTE: A SAN configuration using a supported Fibre Channel switch hardware is required if the Remote Replication premium feature is activated on the storage array. For specific cabling requirements for Remote Replication, see Remote Replication Cabling Example.

SAN-Attached Cabling Example

The following figure shows a three-server, mixed HBA cabling configuration that uses two separate switch fabrics to establish multiple paths to the storage array. Port-to-port connections in each switch fabric/zone are detailed in the text boxes.
