IBM Increases Performance, Memory Capacity For pSeries 655

IBM is introducing new enhancements to the IBM eServer p655 that further increase performance, operational flexibility and memory capabilities -- all key elements required to meet the challenges of high performance and business intelligence computing. As one of IBM's premier UNIX eServer products, the p655 is a key driver of IBM's growth in the market, a market where IBM is the fastest growing UNIX vendor in the world.

IBM's innovative POWER technology is at the heart of the eServer p655 and many of the other systems on the recent TOP500 List of Supercomputers -- meeting the high-performance needs corporate computing demands. Organizations like the Arctic Region Supercomputing Center are utilizing the IBM p655 technology to further advance their high-performance computing projects.

New enhancements to the p655 include:

• An 8-way 1.7 GHz POWER4+ processor option for the IBM p655, providing as much as 19.6% more performance at the same system price as previously available with 8-way 1.5 GHz POWER4+ processors.
• A new DC Power Converter Assembly allows up to four 8GB or 16GB memory cards, doubling the maximum memory capacity to 64GB for 1.5 and 1.7 GHz p655 systems.
• For decision support applications, a cluster of four 4-way p655 servers with 1.7 GHz POWER4+ processors is the industry-leading, 16-processor system in both performance and price/performance, based on the TPC-H (1TB) benchmark.
• Up to 64 p655 servers are supported in the IBM eServer Cluster 1600 for building high-performance clusters. The Cluster 1600 includes IBM pSeries servers, cluster management software, optional cluster software for HPC, and either an industry standard, SP Switch2 or IBM eServer pSeries High Performance Switch interconnection.

The p655 may be configured with up to four dynamic logical partitions (LPARs) with the AIX 5L v5.2 operating system and up to four static LPARs with AIX 5L v5.1. For AIX 5L running in an LPAR or on a network-attached pSeries system, the p655 supports as many as four static LPARs running the Linux operating system.
