Results Showcase Sun Fire(TM) V890 Server, Solaris(TM) 10 OS Performance and Price/Performance Leadership on Sybase Database IQ

SANTA CLARA, Calif., Sept. 1 /PRNewswire-FirstCall/ -- Sun Microsystems, Inc. (NASDAQ: SUNW) today announced Sun's Enterprise class UltraSPARC(R) IV- based Sun Fire(TM) V890 system running the Solaris(TM) 10 Operating System (OS) and Sybase IQ has set a new world record benchmark. Sun demonstrates continued SPARC processor excellence and industry-leading performance and price/performance on the Sun Fire V890 server by offering the following advantages:

    -- Best multi-user performance for any system at the 100GB Scale Factor
       24139 TPC-H throughput@100GB -- more than twice the previous best from
       IBM, 11531 TPC-H throughput@100GB obtained with 16x Opt 2.0GHz
       processors (August 31, 2005)
    -- The dual node Sun Fire V890 with a $/QphH of $46, the Best price-
       performance of any 16-processor configuration at 100GB SF, 35% better
       than the IBM e325 Cluster at $71. (August 31, 2005)
    -- The Sun Fire V890 dual node configuration has the lowest total cost of
       ownership ($485,449) of any 16 processor submission at 100GB, more than
       40% cheaper than the IBM e325 Cluster at $863,410  (August 31, 2005)

    Actual Test Results Conducted by TPC:
    -- The dual node Sun Fire V890 system delivered 10487 QphH@100GB at a
       price performance of $46/QphH@100GB, and with availability date of
       8/5/2005.
    -- The IBM EServer 3215 cluster delivered 12,216 QphH@100GB at a price
       performance of $71/QphH@100GB, and with a scheduled availability of
       11/08/03.

    About TPC-H

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.
