Pseries

The System p, formerly known as RS/6000, was IBM's RISC/UNIX-based server and workstation product line.

In April 2008, IBM announced a rebranding of the System p and its unification with the System i platform. The resulting product line is called IBM Power Systems.

History

It was originally a line of workstations and servers called RS/6000. The server line was then renamed to the eServer pSeries in 2000 as part of its e-Server branding initiative. With the advent of the POWER5 processor in 2004, the family was rebranded the eServer p5. With the global move of the server and storage brands to the System brand with the Systems Agenda, the family was renamed yet again to System p5 in 2005. The System p5 now encompasses the IBM OpenPower product line. With the introduction of POWER6 processor models, the new models were released under the System p brand, dropping the p5 designation.

Processors

Whereas RS/6000 used a mix of early POWER and PowerPC processors, when pSeries came along this had evolved into RS64-III and POWER3 across the board—POWER3 for its excellent floating-point performance and RS64 for its scalability, throughput, and integer performance.

IBM developed the POWER4 processor to replace both POWER3 and the RS64 line in 2001. After that the differences between throughput and number crunching-optimized systems no longer existed. Since then System p machines evolved to use the POWER5 but also the PowerPC 970 for the low-end and blade systems.

The last System p systems used the POWER6 processor, such as the POWER6-based System p 570 and the JS22 blade. In addition IBM introduced during the SuperComputing 2007 (SC07) conference in Reno a new POWER6-based System p 575 with 32 POWER6 cores at 4.7 GHz and up to 256GB of RAM with water cooling.

Features

All IBM System p5 and IBM eServer p5 machines support DLPAR (Dynamic Logical Partitioning) with Virtual I/O and Micro-partitioning.

System p generally uses the AIX operating system and, more recently, 64-bit versions of the Linux operating system.

Current models

System p was rebranded Power Systems in 2008 and these are Power branded systems with Power7 pocessors.
