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.

Blade Server Requirements

Your cluster requires the following components:
• Server modules (cluster nodes)
• Fibre Channel or iSCSI storage subsystem interconnects
• Cluster interconnects (private network)
• Client network connections (public network)
• Operating system and storage management software
