4 Gigabit PCI Express Single Port Fibre Channel Adapter (FC 5773; CCIN 5773)

Overview

The 4 Gigabit PCI Express Single Port Fibre Channel Adapter is a 64-bit, short form factor x4, PCIe adapter with an LC-type external fiber connector that provides single initiator capability over an optical fiber link or loop. The adapter automatically negotiates the highest data rate between the adapter and an attaching device at 1 Gbps, 2 Gbps, or 4 Gbps of which the device or switch is capable. Distances between the adapter and an attaching device or switch can reach up to 500 meters running at 1 Gbps data rate, up to 300 meters running at 2 Gbps data rate, and up to 150 meters running at 4 Gbps data rate. When used with IBM® Fibre Channel storage switches supporting long-wave optics, the adapter can reach distances of up to 10 kilometers running at either 1 Gbps, 2 Gbps, or 4 Gbps data rates.

The adapter can be used to attach devices either directly, or by means of Fibre Channel switches. If you are attaching a device or switch with a SC type fiber connector, you must use an LC-SC 50 micron fiber converter cable (#2456) or a LC-SC 62.5 micron fiber converter cable (#2459).

The adapter has the following features:

• Compliant with the PCIe Base and CEM 1.0a specifications:
  • x1 and x4 lane link interface at 2.5 Gbit/s (auto-negotiated with system)
  • Supports VC0 (1 Virtual Channel) and TC0 (1 Traffic Class)
  • Configuration and IO Memory read/write, completion, message
  • Support for 64 bit addressing
  • ECC error protection
  • Link CRC on all PCIe packets and message information
  • Large payload size: 2048 bytes for read and write
  • Large read request size: 4096 bytes
• Compatible with 1, 2, and 4 Gb Fibre Channel interface:
  • Auto-negotiate between 1 Gb, 2 Gb or 4 Gb link attachments
  • Support for all Fibre Channel topologies: point-to-point, arbitrated loop, and fabric
  • Support for Fibre Channel class 2 and 3
  • Maximum Fibre Channel throughput achieved using full duplex hardware support
• End-to-end data path parity and CRC protection, including internal data path RAMs
• Architectural support for multiple upper layer protocols
• Internal high-speed SRAM memory
• ECC protection of local memory, includes single-bit correction and double-bit protection
• Embedded short-wave optical (LC) connection with diagnostics capability
• Onboard Context Management by firmware (per port):
  • Up to 510 FC Port Logins
  • Up to 2047 concurrent Exchanges
  • I/O multiplexing down to the FC Frame level
• Data buffers capable of supporting 64+ buffer-to-buffer (BB) credits per port for short-wave applications
• Link management and recovery handled by firmware
• Onboard diagnostic capability accessible by optional connection
• Parts and construction compliant with the European Union Directive of Restriction of Hazardous Substances (RoHS)
• Performance up to 4.25 Gbps full duplex

Operating system or partition requirements

The adapter is supported under the following operating systems:

• AIX 5L™ Version 5.3 with the 5300-06 Technology Level, or later
• Red Hat Enterprise Linux version 4 U5
• IBM i 6.1, or later
• Red Hat Enterprise Linux version 5
• SUSE Linux Enterprise Server 9 SP4
• SUSE Linux Enterprise Server 10, SP1

Note: If you are installing a new feature, ensure that you have the software required to support the new feature and that you determine if there are any existing prerequisites. To do this, use the IBM Prerequisite Web site at http://www-912.ibm.com/e_dir/eServerPrereq.nsf.

Adapter LED states

Green and yellow LEDs can be seen through openings in the adapter's mounting bracket. Green indicates firmware operation and yellow signifies port activity. Table 1 summarizes normal LED states. There is a 1 Hz pause when the LED is off between each group of fast blinks (1, 2 or 3). Observe the LED sequence for several seconds to ensure that you correctly identify the state.

Power-On Self Test (POST) conditions and results are summarized in Table 2. These states can be used to identify abnormal states or problems.

Device ID jumper

The default setting for the device ID jumper labeled P0_JX is to set the jumper on pins 1 and 2 as shown in Figure 2. Do not change the jumper settings for a standard installation.

Replacing hot swap HBAs

Fibre Channel host bus adapters (HBAs) connected to a FAStT or DS4000® storage subsystem have a child device called a disk array router (dar). You must unconfigure the disk array router before you can hot swap an HBA that is connected to a FAStT or DS4000 storage subsystem. For instructions, refer to Replacing hot swap HBAs in the IBM System Storage® DS4000 Storage Manager Version 9, Installation and Support Guide for AIX®, HP-UX, Solaris, and Linux on POWER®, order number GC26-7848.
