Lenovo QLogic 20-Port 8 Gb and 4 8 Gb SAN Switch Modules Owner’s Manual

Lenovo QLogic 20-Port 8 Gb and 4 8 Gb SAN Switch Modules

Product Guide (withdrawn product)

The QLogic 20-port 8 Gb and 4/8 Gb SAN Switch Modules for 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.
Figure 1 shows the QLogic 20-port 4/8 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.
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 opensystem fabric functionality using the full-fabric mode or the module with transparent switching functionality using the intelligent pass-thru mode.

Part number information

Table 1 shows the part number to order these modules.

Supported BladeCenter chassis and expansion cards

The QLogic 20-port 8 Gb and 4/8 Gb SAN Switch Modules are supported in the 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

Figure 2. BladeCenter connected to an external IBM System Storage DS3400 storage solution using a CFFv card and standard I/O bays

Table 5 lists the parts that are used in this configuration.
Table 5. Components used as shown in Figure 2

Diagram reference|  Part number / Machine type| Description| Quantity
---|---|---|---
 ①|  Varies|  BladeCenter HS22, HS21, or other supported server|  1 to 14
 ②|  Varies|  Supported CIOv or CFFv expansion card (see   Table 4)|  1 per server
 ③|  Varies|  Supported BladeCenter chassis*|  1
 ④|  44X1905|  QLogic 20-port 8 Gb SAN Switch Modul|  1 or 2
 ⑤|  1726-41X or 1726-42X|  IBM System Storage DS3400 (Single or Dual Controller)|  1
 ⑥|  1727|  Optional IBM System Storage EXP3000 (Single or   Dual ESM)|  1 to 3
 Not shown|  39R6536|  DS3000 Partition Expansion License|  1

• 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 tFhe 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.
  
  Figure 4. Front panel of the I/O module

Table 7 lists the LEDs on the front panel and their meanings. Table 7. LEDs on the front panel

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.
