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 of. 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 that support longwave 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 with Fibre Channel switches. If you are
attaching a device or switch with an SC type fiber connector, you must use an LC-SC 50 micron fiber
converter cable (FC 2456) or an LC-SC 62.5 micron fiber converter cable (FC 2459).
The adapter has the following features:
v Compliant with the PCIe Base and Card Electromechanical (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
v 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 by using full duplex hardware support
v End-to-end data path parity and CRC protection, including internal data path RAMs
v Architectural support for multiple upper layer protocols
v Internal high-speed SRAM memory
v ECC protection of local memory, includes single-bit correction and double-bit protection
v Embedded shortwave optical connection with diagnostics capability
v 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
v Data buffers capable of supporting 64+ buffer-to-buffer (BB) credits per port for shortwave applications
v Link management and recovery handled by firmware
v Onboard diagnostic capability accessible by optional connection
v Parts and construction compliant with the European Union Directive of Restriction of Hazardous
Substances (RoHS)
v Performance up to 4.25 Gbps full duplex
