The History of IBM AIX Systems

The AIX Version 1 was first produced in year 1986 by the IBM 6150 RT workstation, and this was developed from the UNIX System Version releases one and two. The IBM and Interactive systems corporation incorporated also the source codes from the 4.3 and 4.2 BSD UNIX.

IBM would later produce another AIX Version 3 (AIX/600); this was developed from the system V Release 3. From 1990, the AIX has been used as the primary operating system for all the RS/6000 series. The AIX Version 4 was introduced in 1994 and helped to add to the symmetric multi-processing combined with the new introduction of first ever RS/6000 SMP servers. This continued to be developed in 1990s, and eventually lead to AIX 4.3.3 in the year 1999. The Version 4.1 was slightly modified and became the standard operating system of the Apple Network Server systems that were sold by the Apple Computer so as to complement Macintosh line.

In late 1990s, Santa Cruz Operation and IBM under the Project Monterey planned to integrate UnixWare and AIX into one 32 bit/64 bit multi-platform UNIX with specific emphasis on using the Intel IA 64 architecture CPUs. A good version of the AIX-5L for the IA 64 systems was produced, but according to information produced by the SCO v. IBM lawsuit, not than 40 licenses of the finished Monterey Unix were sold before this project got terminated in 2002. In the year 2003, SCO Group claimed that the IBM misappropriated the license code from the UNIX System V Release 4 for incorporating into AIX hence it withdrew the IBM’s license of developing and distributing AIX, but the IBM maintained that the license was irreversible and continued to support and sell the products till the ligation was adjudicated.

The AIX was a section of 2003 SCO v. IBM lawsuit, where the SCO Group had filed a case against IBM, claiming that the IBM diverted some of the SCO Group intellectual property to Linux Codebase. The SCO Group tried to revoke the IBM’s license of distributing and selling the IAX systems by claiming that they were the real owners of Unix Operating System. In 2011 May, a jury ruled that the Novell owns the copyrights to UNIX and not SCO Group.

In May 2007, AIX 6 was announced, and was used to run an Open Beta as from June, 2007 to November 9, 2007 when the general availability Version of AIX 6.1 was made available? The major great features that came with AIX 6.1 include: workload partitions (allows application mobility), full role based access control, Live Partition Mobility on POWER6 hardware, and enhanced security features such as the addition of AES encryption in place of NSF v4 and v3.

In 2010, April, the IBM announced that it will be producing the next 7.1 release. Some of the new features mentioned in this announcement and to be incorporated in this new release include: enhanced clustering, better scalability, and improved management capabilities. IBM also hopes to make the 7.1 release available and it will feature an Open Beta program again.
