Full-Fabric SAN Tips and Techniques
■
In the fabric SAN configuration, the switches communicate with the array host
ports using a fabric point-to-point (F_port) mode. This enables transparent
controller fail-over and fail-back without server-resident software. However,
supporting hot-swap servicing of a failed controller requires the use of
multipathing software, such as the Sun StorEdge Traffic Manager, on the
connected servers.
