In Figure 27, one port from the VIC 1340 adapter is connected to 2204XP Fabric Extender A and one is
connected to 2204XP Fabric Extender B. The result is 10 Gb of bandwidth to each Fabric Extender. The
storage accelerator in slot 3 provides no network connectivity.

In Figure 28, the Storage Accelerator installed in adapter slot 2 acts as a pass-through device, channeling
one port to each of the Fabric Extenders. In addition, one port from the VIC 1340 is channeled to 2204XP
Fabric Extender A and one is channeled to 2204XP Fabric Extender B. The result is 20 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.
