Performance specifications

The 1050EX HBA offers highly integrated 2Gb/s Fibre Channel (FC) connectivity solutions for

storage area networks (SAN), and is designed for use with PCI-Express servers. The 1050EX HBA

is a single-port HBA in a standard-height, half-length card form factor.

The PCI-Express architecture is an open specification designed to address the wide range of current

and future system interconnect requirements. It also defines a flexible, scalable, high-speed, serial,

point-to-point, hot pluggable/hot swappable interconnect that is software-compatible with PCI. This

architecture allows the 1050EX HBA to use the same drivers and management tools as the HBAs

for PCI and PCI-X systems.

This HBA has the following performance features:

• Compliant with the PCI-Express1.0a specification:

• x1 or x4 lane link interface at 2.5Gbit/s per lane (auto-negotiated with system)

• VC0 (1 Virtual Channel) and TC0 (1 Traffic Class) support

• Configuration/IO/memory read/write, completion, message support

• 64-bit addressing support

• 32-bit CRC for all transmitted data packets

• 16-bit CRC on all link message information

• Compatible with both 1 Gigabit (1Gb) and 2 Gigabit (2Gb) FC Interface

• Auto-negotiation between 1Gb and 2Gb link attachments

• High performance FC host adapter with dual internal processors

• Full support for all FC topologies: point-to-point, arbitrated loop, and fabric

• Full support for FC service class 2 and 3

• Maximum FC throughput achieved via full duplex hardware support

• End-to-end data path-parity and CRC protection, including internal data path RAMs

• Architectural support for multiple upper layer protocols

• Internal 32-bit ARM 946E-S processor with instruction and data cache

• Internal SerDes 1Gb/2Gb core

• High speed QDR II external memory with separate read and write data paths

• Device drivers for Windows 2000 and Windows Server 2003

• Drivers for both SCSI and IP (where supported) Protocols

• Driver support for Fibre Channel boot functionality:

• On-board context management by firmware

• Up to 510 FC port logins

• Up to 1024 concurrent exchanges

• I/O multiplexing down to FC frame level

• Large data buffers capable of supporting 16 buffer-to-buffer (BB) credits for short-wave

applications

• Link management and recovery handled by firmware

• On-board diagnostic trace capability accessible via optional connection
