{{POWER, PowerPC, and Power ISA}}
'''IBM Power Systems''' is a family of [[server computer]]s from [[IBM]] that are based on its [[IBM Power microprocessors|Power]] processors. It was created in 2008 as a merger of the [[System p]] and [[IBM AS/400|System i]] product lines.

== History ==

IBM had two distinct POWER- and PowerPC-based hardware lines since the early 1990s:
* Servers running processors based on the [[IBM RS64|IBM PowerPC-AS]] architecture in the [[AS/400]] family (later known as iSeries, then System i) running OS/400 (later known as i5/OS, and now [[IBM i]])
* Servers and workstations using POWER and [[PowerPC]] processors in the [[RS/6000]] family (later known as [[pSeries]], then [[System p]]), running [[IBM AIX]] and [[Linux on Power]].

After the introduction of the [[POWER4]] processor in 2001, there was little difference between both the "p" and the "i" hardware; the only differences were in the software and services offerings. With the introduction of the [[POWER5]] processor in 2004, even the product numbering was synchronized. The ''System i5 570'' was virtually identical to the ''System p5 570''.

In April 2008, IBM officially merged the two lines of servers and workstations under the same name, '''Power''',<ref>{{Cite web|last=Haff|first=Gordon|title=IBM: i + p = Power|url=https://www.cnet.com/news/ibm-i-p-power/|access-date=2020-12-12|website=CNET|language=en}}</ref> and later '''Power Systems''', with identical hardware and a choice of operating systems, software, and service contracts,<ref>{{cite web |url=http://www.ibm.com/systems/power/news/announcement/20080402_annc.html |title=IBM Power Systems: What is the new Power Equation |date=April 2, 2008 |publisher=IBM |archive-url=https://web.archive.org/web/20080802190035/http://www-03.ibm.com/systems/power/news/announcement/20080402_annc.html |archive-date=2008-08-02}}</ref> based formerly on a [[POWER6]] architecture. The PowerPC line was discontinued.

With Release 8 of [[Red Hat Enterprise Linux]], IBM has completed transition of POWER8 and POWER9 servers to [[Endianness|little-endian mode]] for Linux.<ref>{{cite web |last1=IBM |title=IBM United States Software Announcement 219-234 |url=https://www.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_ca/4/897/ENUS219-234/index.html&lang=en&request_locale=en |website=IBM |publisher=International Business Machines Corporation |access-date=26 March 2022}}</ref><ref>{{cite web |last1=IBM |title=IBM United States Software Announcement 219-234 |url=https://www.ibm.com/downloads/cas/US-ENUS219-234-CA/name/ENUS219-234.PDF |website=IBM |publisher=International Business Machines Corporation |access-date=26 March 2022}}</ref><ref>{{cite web |last1=Timothy Prickett Morgan |title=The Transition To RHEL 8 Begins On Power Systems |url=https://www.itjungle.com/2019/06/10/the-transition-to-rhel-8-begins-on-power-systems/ |website=ITJungle |date=10 June 2019 |access-date=26 March 2022}}</ref> AIX and IBM i continue to run in [[endianness|big-endian mode]].
