IBM EN2A PCIe3 16 Gb 2-port Fibre Channel adapter CCIN 579D 02JD564 or sub

Description

The PCIe3 16 Gb 2-port Fibre Channel adapter is an x8, generation 3 (gen3), PCIe adapter. This adapter is a high-performance x8 short form adapter also referred to as a PCIe Host Bus Adapter (HBA). The adapter provides two ports of 16 Gb Fibre Channel capability using SR optics. Each port can provide up to 16 Gb Fibre Channel functions simultaneously.
The FC EN2A is a short, regular height adapter
Each port provides single initiator capability over a fibre link. If you are using N_Port ID Virtualization (NPIV), multiple initiator capability is provided. The ports are SFP+ and include an optical SR transceiver. The ports have little connector-type (LC) and utilize shortwave laser optics. The adapter operates at link speeds of 4, 8, and 16 Gbps and it will automatically negotiate to the highest speed possible. LEDs on each port provide information on the status and link speed of the port.
The adapter connects to a Fibre Channel switch at 4 Gb, 8 Gb, or 16 Gb. It can directly attach to a device without a switch at 16 Gb. The adapter without a Fibre Channel switch attached is not supported at 4 Gb or 8 Gb.
NPIV capability is supported through Virtual I/O Server (VIOS).
The adapter has the following features:
The adapter is compliant with the PCIe base and Card Electromechanical (CEM) 2.0 specifications with the following characteristics:
Provides an x8 lane link interface at 14.025 Gbps, 8.5 Gbps, or 4.25 Gbps (automatic negotiation with system)
Provides support for one Virtual Channel (VC0) and one Traffic Class (TC0)
Provides configuration and I/O memory read and write, completion, and messaging capabilities
Provides support for 64-bit addressing
Provides error correction code (ECC) and error protection functions
