Sun Microsystems Sun Fire(TM) E25K Server with UltraSPARC® IV+ Processors Ups the Ante on IBM with World-Record Setting Performance

SANTA CLARA, Calif., Jan. 30 -- Sun Microsystems, Inc. (NASDAQ:SUNW) announced a world record-breaking data warehousing performance TPC-H SF3000 benchmark result: the Sun Fire(TM) E25K server running UltraSPARC® IV+ processors, the Solaris(TM) 10 Operating System and Oracle® Database 10g Release 2 outperforms IBM's eServer p5 595 by 5 percent (1).

The 72-way 1.5 GHz UltraSPARC IV+ processor-based Sun Fire E25K system with 108 Sun StorEdge SE3510 arrays running the industry-leading Solaris 10 Operating System (OS) and Oracle Database 10g Release 2 achieved 105,430.9 QphH@ 3000GB on the TPC-H SF3000 benchmark.

These results demonstrate the continued dominance of Sun UltraSPARC processor-based systems, Solaris OS on large SMP single-system platforms, and Oracle Database 10g in the most demanding enterprise application environments. This new benchmark result shows better performance for Sun Fire servers over those from IBM when deploying Oracle Database 10g.

Bolstered by Solaris 10 OS, Sun's advanced multi-platform, open source OS, and new Sun Studio 11 software compilers, the Sun Fire E25K server is further optimized for record-setting performance and throughput maximization. The system was able to deliver 20 GB/sec I/O bandwidth which demonstrates the capability of Solaris 10 OS and the StorEdge 3510 FCArray to deliver real world I/O performance.

The TPC-H Benchmark

The Transaction Processing Performance Council's (TPC) TPC-H benchmark measures systems' capability to examine large volumes of data, execute queries with a high degree of complexity, and give answers to critical business questions. TPC-H 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.
