The '''IBM System p''' is a high-end line of [[Reduced instruction set computer|RISC]] ([[IBM Power microprocessors|Power]])/[[Unix|UNIX]]-based servers. It was the successor of the [[RS/6000]] line, and predecessor of the [[IBM Power Systems]] server series.

==History==
The previous [[RS/6000]] line was originally a line of workstations and servers. The first System p server line was named the '''''e''Server pSeries''' in 2000 as part of the e-Server branding initiative.

In 2004, with the advent of the [[POWER5]] processor, the server family was rebranded the '''''e''Server p5'''.<ref>{{Cite web|last=Stokes|first=Jon|date=2004-07-14|title=IBM launches POWER5-based p5 server line|url=https://arstechnica.com/uncategorized/2004/07/3993-2/|access-date=2020-12-11|website=Ars Technica|language=en-us}}</ref>

In 2005, following IBM's move to streamline its server and storage brands worldwide, and incorporating the "System" brand with the Systems Agenda, the family was again renamed to '''System p5'''. The System p5 now encompassed the IBM OpenPower product line.

In 2007, after the introduction of the [[POWER6]] processor models, the last rename under the '''System p''' brand dropped the p (numbered) designation.

In April 2008, IBM announced a rebranding of the System p and its unification with the mid-range [[IBM AS/400|System i]] platform. The resulting product line was called '''[[IBM Power Systems]]'''.

==Hardware and software==
===Processors===

Whereas the previous RS/6000 line used a mix of early [[IBM Power microprocessors|POWER]] and [[PowerPC]] processors, when pSeries came along, this had evolved into [[RS64|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, during the SuperComputing 2007 (SC07) conference in Reno, IBM introduced a new POWER6-based System p 575 with 32 POWER6 cores at 4.7&nbsp;GHz and up to 256&nbsp;GB of RAM with water cooling.

===Features===
All IBM System p5 and IBM ''e''Server p5 machines support [[Dynamic Logical Partitioning|DLPAR (Dynamic Logical Partitioning)]] with Virtual I/O and [[Micro-partitioning]].

{{expand section|date=August 2012}}
System p generally uses the [[AIX operating system]] and, more recently, [[64-bit computing|64-bit]] versions of the [[Linux]] operating system.

The [[IBM]] p690 was, at the time of its release in late 2001, the flagship of IBM's high-end [[Unix]] servers during the [[POWER4]] era of processors. It was built to run IBM [[AIX operating system|AIX]] Unix, although it is possible to run a version of [[Linux]] minus some POWER4-specific features.

It could support up to 32 (1.5, 1.7 or 1.9&nbsp;GHz) POWER4+ processors and 1 [[Terabyte|TB]] of [[Random access memory|RAM]], which weighs well over 1000&nbsp;kg. It was used in a [[supercomputer]] at [[Forschungszentrum Jülich#IBM p690 cluster “Jump” (2004)|Forschungszentrum Jülich]] in 2004, and was discontinued in late 2005.<ref>{{cite web|url=http://www-03.ibm.com/servers/eserver/pseries/hardware/highend/p690.html|archive-url=https://web.archive.org/web/20060113142105/http://www-03.ibm.com/servers/eserver/pseries/hardware/highend/p690.html|url-status=dead|archive-date=January 13, 2006|title=pSeries 690|publisher=[[IBM]]|date=2005-11-08|access-date=2014-02-10}}</ref>

System p was rebranded to [[IBM Power Systems|Power Systems]] in 2008.

===OpenPower===
{{redirect|OpenPower|the organization which promotes the Power ISA|OpenPOWER Foundation}}
'''OpenPower''' was the name of a range of servers in the [[System p]] line from [[IBM]].  They featured IBM's [[POWER5]] [[Central processing unit|CPUs]] and run only 64-bit versions of [[Linux on Power|Linux]]. IBM's own [[UNIX]] variant, [[AIX]] is not supported since the OpenPower servers are not licensed for this [[operating system]].

There were two models available, with a variety of configurations.

Before 2005, OpenPower belonged to the [[eServer]] product line but were eventually rolled into the IBM's [[Power Systems]] product portfolio.
