Alacritech's 1000x1 Storage and Server Accelerators work by effectively offloading TCP/IP and iSCSI (define) protocol processing duties from the system's main processor, bypassing operations such as CPU interrupts and the latency that they create. Applications utilizing SMB(define)/CIFS(define) protocols in particular benefit from this approach.
Tests revealed that under Windows Server 2003, the server bested a Windows NT 4.0 Server Enterprise Edition implementation with an Intel Network Interface Card (NIC) by 212 percent, reaching speeds of 1370 Mbps compared to 439 Mbps for Windows NT 4.0.
When pitted against Windows 2000 Advanced Server, Alacritech's hardware helped Windows 2003 achieve throughput gains of 132 percent, besting the Windows 2000 machine's score of 591 Mbs when mated with an Intel NIC.
The company reports that its accelerators also beat Intel NICs in otherwise identical Windows Server 2003 hardware configurations.
The tests were performed on an HP ProLiant DL760G2 server in an eight-processor configuration outfitted with Alacritech 1000x1 Server and Storage Accelerator cards. Benchmarks were taken with NetBench 7.02 software from Ziff Davis Media.
In describing the product's value to a Windows Server 2003 configuration, Larry Boucher, Alacritech's president and CEO said, "Microsoft's latest server platform helps businesses achieve greater continuity and consolidation without sacrificing performance."
