SUPPLEMENTAL MATERIAL
In Figure 25, two ports from the VIC 1380 are channeled to 2204XP Fabric Extender A and two are
channeled to 2204XP Fabric Extender B. The VIC 1340 slot is empty and adapter slot 2 is empty. The result
is 20 Gb of bandwidth to each Fabric Extender.
Figure 25 VIC 1380 in Adapter Slot 3 (VIC 1340 slot empty and adapter slot 2 empty)
In Figure 26, 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. This configuration requires 4 CPUs.
