QLogic 20-port and 10-port 4 Gb SAN Switch Modules

IBM BladeCenter at-a-glance guide

The QLogic 20-port and 10-port 4 Gb SAN Switch Modules enable high performance 4 Gb Fibre Channel

SAN solutions, and allow IBM BladeCenter integration with any open-standards-based storage area

networks utilizing full fabric switching functionality. These two switches have almost the same features

and functions except for the number of activated ports: the 10-port switch has 10 activated ports and the

20-port switch has 20 activated ports.

Figure 1 shows the QLogic 4 Gb SAN Switch Module.

Did you know?

The switch connects to the midplane directly, without having to use cables or small form-factor pluggable

(SFP) modules. By eliminating these components for up to 14 servers, the resulting savings alone cover

the BladeCenter chassis investment.

The module is licensed to operate in either full-fabric mode or intelligent pass-thru mode. The module

allows BladeCenter integration with any open-standards-based SAN, whether it is an enterprise

open-system fabric functionality using the full-fabric mode or the module with transparent switching

functionality using the intelligent pass-thru mode.

Popular configurations The QLogic 4 Gb SAN Switch Modules can be used in various configurations. Installation in standard switch bays Figure 2 shows the QLogic 20-Port 4 Gb SAN Switch Module installed in standard I/O bays 3 and 4 in a BladeCenter E chassis. The chassis is connected to the IBM System Storage DS3400. The servers in the chassis each have compatible CFFv or CIOv Fibre Channel expansion cards. Figure 2.

Table 7 lists the LEDs on the front panel and their meanings. Table 7. LEDs on the front panel LED name LED description OK This green LED is at the top left of the I/O module on the front panel and indicates that the module is working properly. ! (I/O module fault) This amber LED is at the top right of the I/O module on the front panel. This LED indicates that the I/O module has a fault. If the I/O module fails the POST, this fault LED is lit.
