SANTA CLARA, CA -- Sun Microsystems, Inc. (Nasdaq: SUNW) today announced results for the TPC-H benchmark. Preliminary tests on the Sun Fire(TM) 15K server, Sun StorEdge(TM) arrays, Sun ONE, and Oracle9i have “established” Sun as the fastest performing and best price/performance system on the market. The mainframe class Sun Fire 15K server has conquered a benchmark that IBM mainframes have failed to run so far. This industry standard benchmark was devised in 1999 to represent ad-hoc queries. Because it is less than three years old and is focused on ad-hoc queries, this benchmark is still representative of the real-world decision support and data warehousing applications. The benchmark was performed on a 72-processor 900 MHz Sun Fire 15K system with 288GB of memory, running the industry-leading Solaris(TM) 8 Operating Environment (OE) and Oracle9i Database, topping the performance of the 128 CPU NCR system. The server also utilized 17 Sun StorEdge(TM) A5200 disk arrays. The system delivered 18,802.1 QphH@ 1000GB at a price performance of $287/QphH@1000GB, with a scheduled availability of July 17, 2002. The versatile 72-way Sun Fire 15K server with 900MHz CPUs is rated by Sun at 6,400 Mainframe Equivalent MIPS, far more than the fastest IBM mainframe, and far lower in price. IBM has not run a TPC-H benchmark on its mainframe or IBM p690, which would allow a more detailed comparison. Established by the Transaction Processing Performance Council (TPC), the TPC-H benchmark is an industry-standard Decision Support test designed to measure systems' capability to examine large volumes of data, execute queries with a high degree of complexity, and give answers to critical business questions. The TPC-H benchmark evaluates a composite performance metric (QphH@size) and a price/performance metric ($/QphH@size) that measure the performance of various decision support systems by the execution of sets of queries against a standard database under controlled conditions. TPC-H, QphH and $/QphH are trademarks of the TPC.
