In 

Figure 15

, there is no mezzanine adapter installed. Two ports from the VIC 1240 are channeled to 

2208XP Fabric Extender A and two are channeled to 2208XP Fabric Extender B. The result is 20 Gbps of 
bandwidth to each Fabric Extender.

  Option 2 - VIC 1240 to UCS 2208XP Fabric Extender (no mezzanine adapter)

In 

Figure 16

, two ports from the VIC 1240 are channeled to 2208XP Fabric Extender A and two are 

channeled to 2208XP Fabric Extender B. The result is 20 Gbps of bandwidth to each Fabric Extender. The 
Cisco UCS Storage Accelerator adapter in the adapter 2 slot has no network connectivity.
