NOTE:

It is recommended that you configure the paired inter-switch links (ISLs) as

shown in Figure 1-6 for clusters with Fibre Channel storage systems. In an iSCSI

cluster configuration, multiple connections between internal switch modules and

external switches may not be practical depending on the Ethernet switch features.
