Cisco UCS B420 M4 Blade Server 52
SUPPLEMENTAL MATERIAL
In Figure 19 , four ports from the VIC 1380 are connected to 2304 Fabric Extender A and four are connected
to 2304 Fabric Extender B. The VIC 1340 slot is empty and adapter slot 2 is empty. A native 40G interface is
connected to each of the Fabric Extenders. The result is 40 Gb of bandwidth to each Fabric Extender.
Figure 19 VIC 1380 (VIC 1340 slot empty and adapter slot 2 empty)
In Figure 20 (supported on 4-CPU configurations), 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. This configuration
requires 4 CPUs.
