Overview
The PCIe3 LP 16 Gb 2-port Fibre Channel Adapter is a low-profile, x8, generation 3, PCIe adapter. This
adapter has a little connector-type (LC) external fiber connector that provides single initiator capability
over an optical fiber link. The adapter automatically negotiates the highest data rate between the adapter
and an attaching device at a link speed of 16 Gbps, 8 Gbps, or 4 Gbps. The adapter supports a maximum
link speed of 16 Gbps at both ports. Distances between the adapter and an attaching device or switch can
reach up to 380 m running at a 4 Gbps data rate, up to 150 m running at an 8 Gbps data rate, and up to
100 m running at a 16 Gbps data rate.
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
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
– 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
characteristics:
– 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
support
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
v Provides comprehensive virtualization capabilities with support for N_Port ID Virtualization (NPIV)
and virtual fabric (VF)
v Provides support for message signaled interrupts extended (MSI-X)
v Provides support for 255 VFs and 1024 MSi-X
v Provides an internal, high-speed static random-access memory (SRAM) memory
v Provides ECC protection of local memory that includes single-bit correction and double-bit protection
v Provides an embedded shortwave optical connection with diagnostics capability
v Provides support for an on-board context management by firmware:
– Up to 8192 FC port logins
– I/O multiplexing down to the Fibre Channel frame level
v Provides data buffers capable of supporting 64+ buffer-to-buffer (BB) credits per port for shortwave
applications
v Provides link management and recovery that is handled by firmware
v Provides on-board diagnostic capability accessible by an optional connection
