The IBM System i is IBM’s previous generation of midrange computer systems for IBM i users, and was subsequently replaced by the IBM Power Systems in April 2008. The platform was first introduced as the AS/400 (Application System/400) on June 21, 1988 and later renamed to the eServer iSeries in 2000. As part of IBM’s Systems branding initiative in 2006, it was again renamed to System i. The codename of the AS/400 project was “Silver Lake”, named for the lake in downtown Rochester, Minnesota, where development of the system took place. In April 2008, IBM announced its integration with the System p platform. The unified product line is called IBM Power Systems and features support for the IBM i (previously known as i5/OS or OS/400), AIX and GNU/Linux operating systems.
