In Figure 27, one port from the VIC 1240 is channeled to 2204XP Fabric Extender A and one is channeled to
2204XP Fabric Extender B. The Port Expander Card for VIC 1240
installed in adapter slot 2 acts as a
pass-through device, channeling one port to each of the Fabric Extenders. Adapter slot 3 is empty. The
result is 20 Gb of bandwidth to each Fabric Extender.
Figure 27 VIC 1240 and Port Expander for VIC 1240 in Adapter Slot 2 (adapter slot 3 empty)
In Figure 28, there is no VIC 1240 and no adapter installed in slot 2. In this case, an Emulex
or QLogic
adapter is installed in adapter slot 3. Ports A and B of the adapter card connect to the Fabric E
xtenders,
providing 10 Gb per port.
