SUPPLEMENTAL MATERIAL
In Figure 20, 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.
