SAS solution achieves more than 3.2GBps throughput

LSI Logic Corp. will demonstrate a Serial Attached SCSI (SAS) solution with SQLIO benchmarks greater than 3.2GBps throughput at the Intel IHV Optimization Community this week in San Francisco. This SAS product promises to meet the enterprise application requirements of Microsoft SQL Server 2005 and the coming Microsoft Exchange Server 2007.

LSI Logic's silicon-to systems SAS product portfolio includes host bus adapters, MegaRAID adapters, expanders, switches and storage systems in tandem with the Dual-Core Intel Xeon 5100 series processors. Featuring a PCI Express bus, the SAS solution has achieved 64Kbyte sequential reads of 3.2GBps with 64Kbyte sequential writes of 2.7GBps. In addition, the solution features 256Kbyte random read of 2GBps with 256Kbyte random writes of 2.1GBps.

"Large numbers of servers are being deployed this year using SAS, in large part due to the unprecedented performance and scalability that can be effectively packaged with demanding Business Intelligence applications, such as SQL Server 2005," said Harry Mason, president, SCSI Trade Association, and director of industry marketing, Storage Components Group, LSI Logic. "Throughput is often the bottleneck in these applications and SAS, coupled with the enhanced capabilities of PCI Express, dissolves these performance barriers."

SQLIO is a tool provided by Microsoft to determine the I/O capacity of a disk subsystem and ensure the system is tuned for optimal performance. SQLIO is designed to simulate aspects of the I/O workload of Microsoft SQL Server allowing end users to use SQLIO to measure maximum I/O throughput, summarize certain performance data during the test run and identify performance issues before actual SQL Server deployment.

LSI Logic's SAS component technology enables more than 100 new server models, all based on the recently announced Dual-Core Intel Xeon platform.
