In Figure 18 (supported on 4-CPU configurations), the Storage Accelerator installed in adapter slot 2 acts as
a pass-through device, channeling two ports to each of the Fabric Extenders. In addition, two ports from
the VIC 1340 adapter are channeled to 2208XP Fabric Extender A and two are channeled to 2208XP Fabric
Extender B. The result is 40 Gb of bandwidth to each Fabric Extender. This configuration requires 4 CPUs.

In Figure 19 (supported on 2-CPU configurations), two ports from the VIC 1340 adapter are channeled to
2208XP Fabric Extender A and two are channeled to 2208XP Fabric Extender B. The result is 20 Gb of
bandwidth to each Fabric Extender. The storage accelerator in slot 3 provides no network connectivity.
