Product Description The HHBA-5418/20 are Agilent's low profile, 2 Gb/s, dual-port PCI-X to Fibre Channel Adapters for high performance storage area networks and clustering environments. These products feature two independent fibre channel ports and a PCI-X interface for increased connectivity and higher bandwidth. The low profile host adapters are specifically designed for use in 1U and 2U servers. Performance and Scalability Based on Agilent's Tachyon DX2 single-chip Fibre Channel controller, the HHBA-5418/20 eliminate performance bottlenecks and inter-operability issues associated with dual-port adapters using multi-chip controllers and PCI-to-PCI bridge implementations. Agilent's proven Finite State Machine (FSM) architecture allows performance to scale seamlessly with increased server CPU power.

By contrast, processor-based adapters are limited by the maximum performance of the processor itself. The combination of Agilent's 2 Gb Fibre Channel technology and 133 MHz PCI-X delivers unparalleled performance, scalability and connectivity. The HHBA-5418 and HHBA-5420 products accommodate 1 Gb/s and 2 Gb/s fibre channel devices without hardware modification, preserving investments in legacy systems as well as allowing seamless migration toward new 2 Gb/s SAN installations.

Compatible with SAN environments The HHBA-5418/20 ensures full backward compatibility with 33/66 MHz PCI while providing a smooth upgrade path to the next generation, 133 MHz PCI-X.
