Palo Alto, Calif. - A family of dual-port, PCI-X host bus adapters (HBAs) from Agilent Technologies Inc. is said to eliminate the performance bottlenecks and interoperability issues typically associated with such devices in 2-Gbit/second Fibre Channel storage-area networks (SANs).
The Agilent HHBA-542X family, based on Agilent's Tachyon DX2 single-chip controller, avoids problems associated with HBAs that use multichip controllers and PCI-to-PCI bridges, according to Zack Mihalis, senior HBA marketing manager for Agilent's Storage Networking Division.
The devices provide increased port density and high bandwidth, both of which are needed by data centers coping with large volumes of data traffic, Mihalis said.
The modules have two independent Fibre Channel ports, for a combined data transfer rate of 800 Mbytes/s in full-duplex mode. A 133-MHz PCI-X interface enables bus transfer speeds of up to 1 Gbyte/s, and the modules also accommodate 1-Gbit/s and 2-Gbit/s Fibre Channel devices to preserve investments in legacy systems and to allow migration toward 2-Gbit/s SAN installations. The HBAs are backward-compatible with 33- and 66-MHz PCI, and they provide an upgrade path to 133-MHz PCI-X.
The HHBA-5422, which is sampling now, is available with a small-form-factor pluggable cage for copper or optical media. When it samples in January, the HHBA-5421 will have embedded small-form-factor LC transceivers.
Both HBAs are expected to enter volume production in the first quarter. Prices start around $2,400 in volume.
