Product Positioning

The Cluster 1600 is ideal for enterprise data centers that want to consolidate servers and workloads in order to increase management efficiency and lower cost. It is also ideal for organizations that want to scale workloads beyond the capacity of the largest available symmetric multiprocessor (SMP) servers. These include large-scale databases in commercial enterprises or very large computational models in scientific and technical computing environments.

Statement of General Direction

PSSP for AIX V3.5 is supported on AIX 5L for POWER V5.2 as of May 23, 2003. IBM intends to offer its cluster Licensed Products on AIX V5.2 with PSSP V3.5 by first half 2004: • Parallel Environment for AIX • LoadLeveler for AIX 5L • Parallel Engineering and Scientific Subroutine Library for AIX • General Parallel File System for AIX 5L All statements regarding IBM′s future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only.

IBM has transformed its delivery of hardware and software support services to put you on the road to higher systems availability. Electronic Services is a Web-enabled solution that provides an exclusive, no-additional-charge enhancement to the service and support on the IBM eServer . You should benefit from greater system availability due to faster problem resolution and preemptive monitoring. Electronic Services comprises two separate but complementary elements: IBM Electronic Services news page and IBM Electronic Service Agent . The Electronic Services news page provides is a single Internet entry point that replaces the multiple entry points traditionally used to access IBM Internet services and support. Using the news page enables you to gain easier access to IBM resources for assistance in resolving technical problems. The Electronic Service Agent is a no-additional-charge software that resides on your system to proactively monitor events and transmit system inventory information to IBM on a periodic customer-defined timetable. The Electronic Service Agent tracks system inventory, hardware error logs, and performance information. If the server is under a current IBM maintenance service agreement or within the IBM warranty period, the Service Agent automatically reports hardware problems to IBM. Early knowledge about potential problems enables IBM to provide proactive service that maintains higher system availability and performance. In addition, information collected through the Service Agent will be made available to IBM service support representatives when they help answer your questions or diagnosing problems.
