BiTMICRO Qualifies QLogic Fibre Channel HBAs with E-Disk SAN S2F-J

7/6/2004 - BiTMICRO® Networks, a pioneer in intelligent flash IDE/ATA, SCSI, USB, VME, PMC, CompactPCI, FireWire, Ethernet, and Fibre Channel solid state storage solutions, announced the qualification of its E-Disk®SAN S2F-J with the QLA2340 and QLA2342 host bus adapters (HBAs) from QLogic Corp. (NASDAQ:QLGC).

QLogic's single-port QLA2340 and the dual-port QLA2342 are 64-bit, 133MHz PCI-X to Fibre Channel HBAs that offer 2 Gb performance for SAN and other Fibre Channel applications. On the other hand, the E-Disk®SAN S2F-J is the foundation of BiTMICRO's 2U rackmount Fibre Channel solid state disk (SSD) product line. With dual power supplies, redundant cooling fans, and embedded loop resiliency circuits on the disk I/O cards, the S2F-J has complete enclosure redundancy. It is perfect for environments that have expanding data storage requirements and can be upgraded to RAID or utilized as an expansion drive shelf behind another E-Disk®SAN Fibre Channel RAID system.

Benchmark tests were conducted at BiTMICRO's state-of-the-art facilities in Fremont, California. Using a SuperMicro SuperServer with a dual Xeon 2.6 GHz CPU and 1 GB DDR-266 memory as host, lab engineers attached a QLogic dual-port QLA2342 to an E-Disk®SAN S2F-J equipped with twelve 2 Gb E-Disk® Fibre Channel SSDs. IOmeter test results show that both products were able to deliver an outstanding 112,000 IOPS (max), sequential read rates of up to 681 MB/sec and sequential write rates of up to 403 MB/sec. Sustained random rates peaked at 560 MB/sec for reads and 257 MB/sec for writes.

"QLogic HBAs enable BiTMICRO® E-Disk®SAN users to fully utilize the power of their Fiber Channel solid-state storage solutions. Through this alliance we can build on each other strengths and provide enterprises with next-generation SAN solutions," says Frank Berry, Vice President of Marketing, QLogic Corp. "Acquiring BiTMICRO's seal of approval is in line with our goal of becoming the perfect choice for multi-vendor requirements," Berry adds.

"BiTMICRO® remains committed in identifying storage networking components that would complement the performance of our SAN arrays," states Rudy Bruce, President of BiTMICRO Networks. "We're glad to report that QLogic HBAs can keep up with the I/O performance of the E-Disk®SAN S2F-J, thereby assuring our customers that they can easily maximize the performance of their E-Disk® using COTS solutions."
