(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.

, 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. Two
identical
Cisco UCS Storage Accelerator adapters are installed in
slots 2 and 3, but the one in slot 3 provides no network connectivity. This configuration requires 4 CPUs.
