(NYSE:HIT) and the only provider of Services Oriented Storage Solutions, today announced that its flagship Hitachi Universal Storage Platform V

earned the highest Benchmark 2 performance result of any storage system in its class, according to the Storage Performance Council (SPC). Under the SPC-2 methodology, the Hitachi USP V achieved an aggregated average of 8,724.67 SPC-2 MBPS(TM) with a single storage controller, surpassing the performance levels of competitor enterprise storage systems tested by eight-fold.

"Hitachi Data Systems' SPC-2 benchmark results confirm our earlier published findings for achieving the highest levels of enterprise storage performance and scalability in real-world configurations," said Roberto Basilio, Vice President of Storage Platforms Product Management, Hitachi Data Systems. "The Hitachi USP V is a best-in-class, cost-effective, storage platform that provides customers operational consolidation and depth of storage-based services deliverable to a wide range of applications and operating environments, while also lowering costs and complexity."

The new SPC-2 benchmark results reaffirm several key benefits the Hitachi USP V platform provides customers including: -0- Greater Productivity: Sustain significantly more business transactions than any other enterprise storage system in the market, boosting sales and profitability Increased Efficiency: Greatly improve application response time to single digit millisecond levels and support more users and more applications, and handle more capacity on a centrally managed platform that leverages years of mature and reliable hardware and software development Lower TCO: Run a multitude of heterogeneous applications, from transactional workloads such as Microsoft Exchange and Oracle Database 11g to sequential ones such as Video on Demand (VOD) type, concurrently on a single storage controller Reduced Risk: If your applications don't perform well then your business suffers--performance definitively matters to business success

The SPC-2 benchmark consists of three distinct workloads designed to demonstrate the performance of a storage subsystem during the execution of business critical applications that require the large-scale, sequential movement of data. Those applications are characterized predominately by large I/Os organized into one or more concurrent sequential patterns. The SPC benchmark results provide a source of comparative storage performance information that is objective, relevant, and verifiable. These results complement the established performance achievements of the landmark Hitachi USP V, which continues to lead the industry in maximum cached IOPS, delivering over 4.0 million peak cached IOPS.
