SAN fabric dual-controller, redundent connections
The following illustrations show a redundant SAN fabric, fibre channel connection from each controller to
multiple HBAs in the same host (redundant host connection).
The Fibre Channel switches are connected together through the Inter-Switch Link (ISL) to form a single
SAN fabric.
In the following illustration, the Fibre Channel switches are not connected together through an ISL. Each
switch forms its own SAN fabric. This configuration is also the configuration to use for a dual-node
cluster configuration.
