SUPPLEMENTAL MATERIAL

In Figure 16, two ports from the VIC 1340/1240 are channeled to 2208XP Fabric Extender A and two are

channeled to 2208XP Fabric Extender B. The Port Expander Card installed in adapter slot 2 acts as a

pass-through device, channeling two ports to each of the Fabric Extenders. In addition, the VIC 1380/1280

channels four ports to each Fabric Extender. The result is 80 Gb of bandwidth to each Fabric Extender.

In Figure 17, four ports from the VIC 1380 are channeled to 2208XP Fabric Extender A and four are

channeled to 2208XP Fabric Extender B. The VIC 1340 slot is empty and adapter slot 2 is empty. The result

is 40 Gb of bandwidth to each Fabric Extender.
