Major new features in AIX 6. 1 included full role-based access control, workload partitions ( which enable application mobility ), enhanced security ( Addition of AES encryption type for NFS v3 and v4 ) and Live Partition Mobility on the POWER6 hardware.

* AIX version 6. 1 information center

* AIX version 6. 1 overview

Another example is System Workload Partitions ( WPARs ), introduced in the IBM AIX 6. 1 operating system.

DPS 6 and DPS 4 ( ex-Level 62 ) were superseded by Motorola 68000-and later on PowerPC minicomputers running Unix and the product lines were discontinued, though GCOS 6 ran in an emulator on top of AIX.

It has versions compatible with Linux on the i386, DEC Alpha, m68k, PowerPC and SPARC architectures, with FreeBSD, with Solaris, with IRIX64 6. 4, and with AIX.

AIX supports USB mass storage devices since the 5. 3 T9 and 6. 1 T3 releases, but it is not well supported and lacks some features ( like partitioning and using it as general block device in system ).

SFU 2. 0 supported the following UNIX versions: Solaris 2. 6 +, HP-UX 10. 2 +, AIX 4. 2 +, Tru64 UNIX 5. 0 +, and Red Hat Linux 5. 1 +.

*** 4 SMT threads per core ( available in AIX 6. 1 TL05 ( releases in April 2010 ) and above )

Examples of such systems are Solaris 2. 0 / SunOS 5. 0, Windows NT, the Linux kernel 2. 6 and 3. x, AIX and some BSD systems ( NetBSD, since version 5 ).

* PowerHA 7. 1 was released in 2010 and uses the Cluster Aware AIX ( CAA ) infrastructure available in AIX V6. 1 TL 6 and AIX 7. 1

* PowerHA 6. 1, Rebranded again to IBM PowerHA SystemMirror for AIX, GA Oct 27 2009,

The 6. 1 release of the TSM Server is supported on AIX, HP-UX, Linux, Solaris, and Windows Server.

AIX was the first operating system to utilize journaling file systems, and IBM has continuously enhanced the software with features like processor, disk and network virtualization, dynamic hardware resource allocation ( including fractional processor units ), and reliability engineering ported from its mainframe designs.

AIX Version 1, introduced in 1986 for the IBM 6150 RT workstation, was based on UNIX System V Releases 1 and 2.

A beta test version of AIX 5L for IA-64 systems was released, but according to documents released in the SCO v. IBM lawsuit, less than forty licenses for the finished Monterey Unix were ever sold before the project was terminated in 2002.

AIX was a component of the 2003 SCO v. IBM lawsuit, in which the SCO Group filed a lawsuit against IBM, alleging IBM contributed SCO's intellectual property to the Linux codebase.

The original AIX ( sometimes called AIX / RT ) was developed for the IBM 6150 RT workstation by IBM in conjunction with Interactive Systems Corporation, who had previously ported UNIX System III to the IBM PC for IBM as PC / IX.

Much of the AIX v2 kernel was written in the PL / I programming language, which proved troublesome during the migration to AIX v3.

AIX PS / 2 ( also known as AIX / 386 ) was developed by Locus Computing Corporation under contract to IBM.

AIX / 370 was IBM's third attempt to offer Unix-like functionality for their mainframe line, specifically the System / 370 ( the prior versions were a TSS / 370 based Unix system developed jointly with AT & T c. 1980, and VM / IX a VM / 370 based system developed jointly with Interactive Systems Corporation c. 1984 ).

AIX / 370 was released in 1990 with functional equivalence to System V Release 2 and 4. 3BSD as well as IBM enhancements.

With the introduction of the ESA / 390 architecture, AIX / 370 was replaced by AIX / ESA in 1991, which was based on OSF / 1, and also ran on the System / 390 platform.

AIX / ESA, while technically advanced, had little commercial success, partially because UNIX functionality was added as an option to the existing mainframe operating system, MVS, which became MVS / ESA OpenEdition in 1999.

The default shell was Bourne shell up to AIX version 3, but was changed to Korn shell ( ksh88 ) in version 4 in view of XPG4 and POSIX compliance.

* The original Star Desktop evolved into the ViewPoint Desktop and later became GlobalView which was ported to various Unix platforms, such as SunOS Unix and AIX, A Mesa to C compiler was written and the resulting code compiled for the target platform.

This was an entirely new product, not a port of the existing OS / 2, that borrowed certain sections of code from both the existing OS / 2 and AIX products while using an entirely new microkernel code base and adding major features including a system registry and a new driver model.

In 1988, IBM announced AIX / 370, also developed by Locus Computing.

In June 2006, Rave Motion Pictures announced a partnership with Christie / AIX to install 445 digital cinema systems in its theaters.

* AIX 4. 2, May 17, 1996

In May, 2001, a second journaled file system, Enhanced Journaled File System ( JFS2 ), was made available for AIX 5L.

* The Gypsy Life ( AIX Records, 2007 )

AIX PS / 2, first released in 1989, ran on IBM PS / 2 personal computers with Intel 386 and compatible processors.

Unlike AIX / 370, AIX / ESA ran both natively as the host operating system, and as a guest under VM.

At the height of its success, FrameMaker ran on more than thirteen UNIX platforms, including NeXT Computer's NeXTSTEP and IBM's AIX operating systems.

It ran on top of AIX, HP-UX, OS / 2, Windows NT, and a new Apple OS kernel called NuKernel.

In the mid-1990s, IBM released a clustered DB2 implementation called DB2 Parallel Edition, which initially ran on AIX.

The system ran IBM's AIX operating system.

Faced with poor performance ; low acceptance of the PowerPC Reference Platform ( on which the initial offering ran ); poor quality of the PowerPC 620 platform ; extensive cost overruns ; lack of AIX, Windows, or OS / 400 kernel personalities ; and resulting low customer demand, the project was cancelled.

The system was introduced in 1986 as the RT PC ( RISC Technology Personal Computer ) and ran AIX 1. x and 2. x, the Academic Operating System ( AOS ), or the Pick operating system.

PowerAnimator ran natively on MIPS based SGI IRIX and IBM AIX systems up until the late 1990s when it was superseded by Maya.
