LSI promises big SAS boosts for Enterprise Applications

LSI Logic Corporation demonstrated a SAS (Serial Attached SCSI) solution delivering SQLIO benchmarks of greater than 3.2 GB/s throughput.

This demonstration allows end users to realize the performance, scalability and quality delivered by SAS storage products to meet the enterprise application requirements of Microsoft SQL Server 2005 and the coming Microsoft Exchange Server 2007.

This groundbreaking demonstration features the LSI silicon-to systems SAS product portfolio including host bus adapters, MegaRAID(R) adapters, expanders, switches, and storage systems in tandem with the Dual-Core Intel(R) Xeon(R) 5100 series processors.

Featuring a PCI Express bus, the SAS solution has achieved 64KB sequential reads of 3.2 GB/s with 64KB sequential writes of 2.7 GB/s. In addition, the solution will demonstrate 256KB random read of 2.0 GB/s with 256KB random writes of 2.1 GB/s.

SQLIO is a tool provided by Microsoft to determine the Input/Output 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.
