(supported on 2-CPU configurations), two ports from the VIC 1340 adapter are channeled to
2304 Fabric Extender A and two are channeled to 2304 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 also has the port expander capability to
increase the overall network I/O to the server. It acts as a pass-through device to provide two additional
ports to each of the port groups and thus create a native 40G interface to each of the Fabric Extenders. 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.
