A family of midrange servers from IBM that are based on IBM's POWER CPUs and run under the i5/OS, OS/400 and AIX operating systems. Windows and Linux can also be run in an attached x86-based server (see IXS). Officially known as the eServer iSeries 400, the iSeries is IBM's small to medium size business computer line, and more than 20,000 applications have been written for it. Programming is typically done in RPG and COBOL. Originally launched as the AS/400 in 1988, the first iSeries models were introduced in 2000 and were built on IBM's POWER4 CPUs.
An Integrated Database
The iSeries (AS/400) family has always been unique because it included an integrated database with the system. The integrated database evolved from IBM's System/38, introduced in 1978.
AS/400 to iSeries to i5
In 2004, IBM introduced the eServer i5, once again, changing the name of the line. i5 servers use the POWER5 CPU. See i5 and AS/400.
