PCIe3 16 Gb 2-port Fibre Channel Adapter (FC EL5B; CCIN 577F)

Learn about the specifications and operating system requirements for the feature code (FC) EL5B adapter.
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.
Each port provides single initiator capability over a fibre link or with 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 will
automatically negotiate to the highest speed possible. LEDs on each port provide information on the
status and link speed of the port.
N_Port ID Virtualization (NPIV) capability is supported through VIOS.
The adapter has the following features:
v This adapter has parts and construction compliant with the European Union Directive of Restriction of
Hazardous Substances (RoHS)
v 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
– 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
– Provides link cyclic redundancy check (CRC) on all PCIe packets and message information
– Provides a large payload size of 2048 bytes for read and write functions
– Provides a large read request size of 4096 bytes
v The adapter is compatible with 4, 8, and 16 Gb Fibre Channel interface with the following
– Provides for automatic negotiation between 4 Gb, 8 Gb, or 16 Gb link attachments
– Provides support for the following Fibre Channel topologies: point-to-point (16Gb only) and fabric
– Provides support for Fibre Channel class 3
– Provides a maximum Fibre Channel throughput that is achieved by using full duplex hardware
v The adapter provides an end-to-end data path parity and CRC protection, including internal data path
random-access memory (RAM)
v Provides architectural support for multiple upper layer protocols
