QLogic 8 Gb and 4/8 Gb Intelligent Pass-thru Modules for IBM BladeCenter

IBM Redbooks Product Guide

Abstract

The QLogic 8 Gb and 4/8 Gb Intelligent Pass-thru Modules for IBM BladeCenter provide seamless integration of an IBM BladeCenter solution into existing Fibre Channel storage networks using N_Port ID Virtualization (NPIV) technology. Each module concentrates multiple blade servers into the external ports, which in turn connect to external Fibre Channel switches that support NPIV. The pass-thru module presents one or more blade servers per port to the fabric. The module expands the fabric, but unlike a full fabric switch, it does not count against the fabric domain.

Did you know?

The QLogic 8 Gb and 4/8 Gb Intelligent Pass-thru Modules are the latest Fibre Channel NPIV switching option for the IBM BladeCenter. 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.

Features

The QLogic 8 Gb and 4/8 Gb Intelligent Pass-thru Modules have the following features:
  • Six external autosensing Fibre Channel ports (2, 4, or 8 Gbps for 8 Gb SFP+ transceivers, and 1, 2, or 4 Gbps for 4 Gb SFP transceivers) that operate as TF_Ports (Transparent Fabric Ports) at a maximum speed of 8 Gbps
  • The QLogic 8 Gb Intelligent Pass-thru Module has 14 internal Fibre Channel ports that operate as TH_Ports (Transparent Host Ports) at 2, 4, or 8 Gbps depending on FC expansion cards installed into blades
  • The QLogic 4/8 Gb Intelligent Pass-thru Module has 14 internal Fibre Channel ports that operate as TH_Ports (Transparent Host Ports) at 2, 4, or 8 Gbps depending on FC expansion cards installed into blades and the I/O module bays the module is installed in:
    • When installed in an MSIM (BladeCenter H only) or MSIM-HT (BladeCenter HT only), the internal ports operate at up to 8 Gbps
    • When installed in standard I/O module bays 3 or 4, the internal ports operate at up to 4 Gbps
    • When installed in a BladeCenter T chassis, the internal ports operate at 2 Gbps

Note: Neither the QLogic 8 Gb Intelligent Pass-thru Module nor the QLogic 4/8 Gb Intelligent Pass-thru Module can be upgraded to a full-fabric switch module.

The following software feature comes with each module:
  • QuickTools Web interface

Each module supports the following fabric management (all management connections go through the management module):
  • Web interface through QuickTools
  • Command-line interface (CLI) through the Telnet program
  • Enterprise Fabric Suite 2007 application
  • Switch SNMP agent, which enables a network management workstation to receive configuration values, traffic information, and FC failure data through SNMP and the Ethernet interface


Supported BladeCenter chassis and expansion cards

The QLogic 8 Gb and 4/8 Gb Intelligent Pass-thru Modules are supported in the IBM BladeCenter chassis as listed in Table 3. The I/O 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 8 Gb and 4/8 Gb Intelligent Pass-thru Module in the one chassis is not supported.

Popular configurations

Figure 2 shows the QLogic 8 Gb Intelligent Pass-thru Module that is installed in standard I/O bays in the BladeCenter chassis. The chassis is connected to the IBM System Storage SAN40B-4 Fibre Channel fabric switch. The servers in the chassis each have compatible CFFv or CIOv Fibre Channel expansion cards.

Tip: Had the QLogic 4/8 Gb Intelligent Pass-thru Module been used in this configuration, the internal ports of the Pass-thru Module operate at 4 Gbps.

Connectors and LEDs

The front panel of the QLogic 8 Gb and 4/8 Gb Intelligent Pass-thru Modules contain the following components, as shown in Figure 3:
  • 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 6 lists the LEDs on the front panel and their meanings.

Table 6. 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 requirements:
  • 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 level requirements:
  • Operating: 8% to 80%, noncondensing
  • Non-operating: 5% to 80%, noncondensing
