The QLogic 20-port 8 Gb and 4/8 Gb SAN Switch Modules for IBM BladeCenter are a high-speed addition to the BladeCenter switch portfolio. Each module helps enable scalability in storage area network (SAN) size and complexity while maintaining ease of management. These modules are full-fabric Fibre Channel (FC) switches which enables high performance SAN connectivity of up to 8 Gbps.

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.

These switch modules are licensed to operate in either full-fabric mode or intelligent pass-thru mode. These modules allow 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.

  • The QLogic 20-port 8 Gb SAN Switch Module has 14 internal Fibre Channel ports that operate as F_ports (fabric ports) at 2, 4, or 8 Gbps, depending on FC expansion cards installed into blades
  • The QLogic 20-port 4/8 Gb SAN Switch Module has 14 internal Fibre Channel ports that operate as F_ports (fabric ports) at 2 Gbps, 4 Gbps, or 8 Gbps, depending on FC expansion cards installed into blades and the I/O module bays the switch is installed in:

Supported BladeCenter chassis and expansion cards

The QLogic 20-port 8 Gb and 4/8 Gb SAN Switch Modules are supported in the IBM BladeCenter chassis as listed in Table 3. The switch module fits in a standard I/O bay (bays 3 & 4) and, with the addition of the Multi-Switch Interconnect Module (MSIM) in the BladeCenter H and HT, can also fit in a high-speed I/O bay (bays 7-10). Installing both QLogic 20-port 8 Gb and 4/8 Gb SAN Switch Modules in the one chassis is not supported.

Popular configurations

The QLogic 20-port 8 Gb and 4/8 Gb SAN Switch Module can be used in various configurations.

Installation in standard switch bays

Figure 2 shows the QLogic 20-port 8 Gb SAN Switch Module that is installed in standard I/O bays in the BladeCenter 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. The Redundant Array of Independent Disks (RAID) functionality is provided by the external storage system.

Tip: Had the QLogic 20-port 4/8 Gb SAN Switch Module been used in this configuration, the internal ports of the switch would operate at 4 Gbps.

* The expansion card can be installed in servers in the BladeCenter S (8886). However, by doing so, you lose the ability to connect to the BladeCenter S Disk Storage Modules (DSMs). The Fibre Channel expansion card goes in place of the SAS expansion card that is needed to connect to the DSMs.

This configuration also requires cabling between the chassis and the storage server and between the storage server and expansion units. (The cable part numbers are not listed in the table.)

Installation in BladeCenter H high-speed switch bays

Figure 3 shows the QLogic 20-port 4/8 Gb SAN Switch Module installed in MSIMs in the BladeCenter H chassis. The chassis is connected to the IBM System Storage DS3400. The servers in the chassis each have compatible CFFh Fibre Channel expansion cards. The RAID functionality is provided by the external storage system. In this configuration the internal ports of the Switch Module operate at 8 Gbps.

Connectors and LEDs

The front panel of the QLogic 20-port 8 Gb and 4/8 Gb SAN Switch Module contain the following components, as shown in Figure 4:
  • Information LEDs that display the status of the I/O module and its network connections.
  • Six external Fibre Channel ports to connect Fibre Channel devices and switches. These ports are labeled 0, 15, 16, 17, 18, and 19 (from top to bottom) on the I/O module.

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.

External port logged-in (LOG)

There are six green external port logged-in (LOG) LEDs. When one of these LEDs is lit, it indicates that there is a connection (or link) to a device on that port.

External port activity (TX/RX)

There are six green external port activity (TX/RX) LEDs. When one of these LEDs flashes, it indicates that data is being received or transmitted (that is, activity is occurring) on that port. The flash frequency is proportional to the amount of traffic on that port.

External port fault (!)

There are six amber external port fault (!) LEDs. When an external port fault LED is lit, it indicates that the external port has failed the internal, external, or online port diagnostics tests.

Operating environment

The environment has the following temperature and altitude:
  • Operating:
    • 10 - 52 °C (50 - 125 °F) at an altitude of 0 to 914 m (0 to 3,000 ft)
    • 10 - 49 °C (50 - 20 °F) at an altitude of 0 to 3,000 m (0 to 10,000 ft)
  • Non-operating:
    • 40 - 65 °C (-40 - 149 °F) at an altitude of 0 to 12,000 m (0 to 39,370 ft)

The environment has the following humidity levels:
  • Operating: 8% to 80%, noncondensing
  • Non-operating: 5% to 80%, noncondensing
