Editing IBM AS/400 (section)

=== Rebranding ===
The AS/400 family line was rebranded several times in the 1990s and 2000s as IBM introduced newer generations of hardware and operating system.<ref name="as400-technical-introduction">{{cite web |author=Tom Van Looy|date=January 2009 |title=The IBM AS/400: A technical introduction |website=scss.tcd.ie |url=https://www.scss.tcd.ie/SCSSTreasuresCatalog/hardware/TCD-SCSS-T.20121208.068/IBM-AS400-technical-introduction.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://www.scss.tcd.ie/SCSSTreasuresCatalog/hardware/TCD-SCSS-T.20121208.068/IBM-AS400-technical-introduction.pdf |archive-date=2022-10-09 |url-status=live |access-date=2021-03-13}}</ref> 

In 1994, the ''AS/400 Advanced Series'' name was used for new models, followed by the rebranding of the product line to ''AS/400e'' (the ''e'' standing for [[Online business|e-business]]) in 1997.{{sfnp|Soltis|2001|p={{pn|date=October 2023}}}}

In 2000, the ''eServer iSeries'' was introduced as part of its ''[[IBM eServer|eServer]] branding initiative''.<ref>{{cite web|title=IBM eServer iSeries 400|url=https://www-01.ibm.com/common/ssi/rep_ca/9/897/ENUS100-309/index.html|date=October 3, 2000|publisher=IBM}}</ref> The eServer iSeries was built on the [[POWER4]] processor from the RS64 processors used by previous generations, meaning that the same processors were used in both the iSeries and [[pSeries]] platforms, the latter of which ran [[AIX]].

In 2004, ''eServer i5'' (along with OS/400 becoming ''i5/OS'') the ''5'' signifying the use of [[POWER5]] processors, was introduced, replacing the eServer iSeries brand.<ref>{{cite web|author=Denny Insell |url=https://www.gateway400.org/documents/Gateway400/Handouts/2004%20IBM%20eServer%20i5%20Exec%20Overview%2009-09-2004%20St%20Louis%20MOL.pdf |url-status=live |access-date=2021-03-14 |archive-url=https://ghostarchive.org/archive/20221009/https://www.gateway400.org/documents/Gateway400/Handouts/2004%20IBM%20eServer%20i5%20Exec%20Overview%2009-09-2004%20St%20Louis%20MOL.pdf |archive-date=2022-10-09 |title=Introducing IBM eServer i5 & i5/OS|publisher=IBM|date=2004}}</ref>  Successive generations of iSeries and pSeries hardware converged until they were essentially the same hardware sold under different names and with different operating systems.<ref name="system-p-i" /> Some i5 servers were still using the AS/400-specific IBM Machine Type (MT/M 9406-520) and were able to run AIX in a [[logical partition]] along i5/OS, while the p5 servers were able to run i5/OS, respectively. The licensing for AIX and i5/OS was controlled in the firmware by the POWER hypervisor.

The final rebranding occurred in 2006, when IBM rebranded the eServer i5 to ''System i''.<ref>{{cite web |author=Alex Woodie|date=2017-10-11 |url=https://www.itjungle.com/2017/10/11/ibm-slow-catch-mean/ |title=IBM i Slow to Catch On, But What Does It Mean?|access-date=2021-03-15 |website=itjungle.com}}</ref>

In April 2008, IBM introduced the [[IBM Power Systems]] line, which was a convergence of System i and System p product lines.<ref name="Niccolai"/> The first Power Systems machines used the [[POWER6]] processors; i5/OS was renamed as ''IBM i'' in order to remove the association with POWER5 processors.<ref>{{cite web|title=IBM Introduces the First in a New Generation of Power Systems|url=https://www-03.ibm.com/press/us/en/pressrelease/23795.wss |archive-url=https://web.archive.org/web/20080511231914/http://www-03.ibm.com/press/us/en/pressrelease/23795.wss |url-status=dead |archive-date=May 11, 2008 |date=2008-04-02|access-date=2021-03-15 |publisher=IBM}}</ref> IBM i is sold as one of the operating system options for Power Systems (along with AIX and Linux) instead of being tied to its own hardware platform.
