Condition: Refurbished
The 4 Gigabit PCI Express Dual 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.
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
