RISCworkstation, AIX now supports or has supported a wide variety of hardware platforms, including the IBM RS/6. POWER and Power. PC- based systems, IBM System i, System/3. PS/2personal computers, and the Apple Network Server. AIX is based on UNIX System V with 4. BSD- compatible extensions. It is one of six commercial operating systems that have versions certified to The Open Group's UNIX 0. OS, Solaris, Inspur K- UX, HP- UX, and euler. OS ).[4]The AIX family of operating systems debuted in 1. RS/6. 00. 0 series on its launch in 1. IBM. It is currently supported on IBM Power Systems alongside IBM i and Linux. AIX was the first operating system to have a journaling file system, and IBM has continuously enhanced the software with features such as processor, disk and network virtualization, dynamic hardware resource allocation (including fractional processor units), and reliability engineering ported from its mainframe designs.[5]History[edit]IBMRS/6. AIX file servers used for ibm. AIX Version 4 console login prompt. Unix started life at AT& T's Bell Labs research center in the early 1. DECminicomputers. By 1. 97. 6, the operating system was in use at various academic institutions, including Princeton, where Tom Lyon and others ported it to the S/3. OS under VM/3. 70.[6] This port would later grow out to become UTS,[7] a mainframe Unix offering by IBM's competitor Amdahl Corporation.[8] IBM's own involvement in Unix can be dated to 1. Bell Labs in doing its own Unix port to the 3. ESS switch's software). In the process, IBM made modifications to the TSS/3. Unix.[9]It took until 1. IBM to offer its own Unix on the S/3. IX/3. 70, which was developed by Interactive Systems Corporation and intended by IBM to compete with Amdahl UTS.[1. The operating system offered special facilities for interoperating with PC/IX, Interactive/IBM's version of Unix for IBM PC compatible hardware, and was licensed at $1. AIX Version 1, introduced in 1. IBM 6. 15. 0 RTworkstation, was based on UNIX System V Releases 1 and 2. In developing AIX, IBM and Interactive Systems Corporation (whom IBM contracted) also incorporated source code from 4. BSD UNIX. Among other variants, IBM later produced AIX Version 3 (also known as AIX/6. System V Release 3, for their POWER- based RS/6. Since 1. 99. 0, AIX has served as the primary operating system for the RS/6. IBM e. Server p. Series, then IBM System p, and now IBM Power Systems). AIX Version 4, introduced in 1. RS/6. 00. 0 SMP servers and continued to evolve through the 1. AIX 4. 3. 3 in 1. Version 4. 1, in a slightly modified form, was also the standard operating system for the Apple Network Server systems sold by Apple Computer to complement the Macintosh line. In the late 1. 99. Project Monterey, IBM and the Santa Cruz Operation planned to integrate AIX and Unix. Ware into a single 3. UNIX with particular emphasis on running on Intel. IA- 6. 4 (Itanium) architecture CPUs. A beta test version of AIX 5. L for IA- 6. 4 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 2. In 2. 00. 3, the SCO Group alleged that (among other infractions) IBM had misappropriated licensed source code from UNIX System V Release 4 for incorporation into AIX; SCO subsequently withdrew IBM's license to develop and distribute AIX. IBM maintains that their license was irrevocable, and continued to sell and support the product until the litigation was adjudicated. AIX was a component of the 2. 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 SCO Group, who argued they were the rightful owners of the copyrights covering the Unix operating system, attempted to revoke IBM's license to sell or distribute the AIX operating system. In March 2. 01. 0, a jury returned a verdict finding that Novell, not the SCO Group, owns the rights to Unix.[1. AIX 6 was announced in May 2. June 2. 00. 7 until the general availability (GA) of AIX 6. November 9, 2. 00. Major new features in AIX 6. Addition of AES encryption type for NFS v. Live Partition Mobility on the POWER6 hardware. AIX 7. 1 was announced in April 2. AIX 7. 1 in September 2. Several new features, including better scalability, enhanced clustering and management capabilities were added. AIX 7. 1 includes a new built- in clustering capability called Cluster Aware AIX. AIX is able to organize multiple LPARs through the multipath communications channel to neighboring CPUs, enabling very high- speed communication between processors. This enables multi- terabyte memory address range and page table access to support global petabyte shared memory space for AIX POWER7 clusters so that software developers can program a cluster as if it were a single system, without using message passing (i. Inter- process Communication). AIX administrators can use this new capability to cluster a pool of AIX nodes. By default, AIX V7. Pinning kernel memory and the kernel stack for applications with real- time requirements can provide performance improvements by ensuring that the kernel memory and kernel stack for an application is not paged out.[1. AIX 7. 2[1. 5] was announced in October 2. December 2. 01. 5. AIX 7. 2 principal feature is the Live Kernel Update capability which allows OS fixes to replace the entire AIX kernel with no impact to applications. AIX 7. 2 was also restructured to remove obsolete components. The networking component, bos. Unlike AIX 7. 1, AIX 7. POWER7 or later processors. Supported hardware platforms[edit]IBM 6. RT[edit]The original AIX (sometimes called AIX/RT) was developed for the IBM 6. 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.[1. According to its developers, the AIX source (for this initial version) consisted of one million lines of code.[1. Installation media consisted of eight 1. M floppy disks. The RT was based on the ROMPmicroprocessor, the first commercial RISC chip. This was based on a design pioneered at IBM Research (the IBM 8. One of the novel aspects of the RT design was the use of a microkernel, called Virtual Resource Manager (VRM). The keyboard, mouse, display, disk drives and network were all controlled by a microkernel. One could "hotkey" from one operating system to the next using the Alt- Tab key combination. Each OS in turn would get possession of the keyboard, mouse and display. Besides AIX v. 2, the PICK OS also included this microkernel. Much of the AIX v. PL/8 programming language, which proved troublesome during the migration to AIX v. AIX v. 2 included full TCP/IP networking, as well as SNA and two networking file systems: NFS, licensed from Sun Microsystems, and Distributed Services (DS). DS had the distinction of being built on top of SNA, and thereby being fully compatible with DS on the IBM midrange AS/4. For the graphical user interfaces, AIX v. X1. 0R3 and later the X1. R4 and X1. 1 versions of the X Window System from MIT, together with the Athena widget set. Compilers for Fortran and C were available. One of the more popular desktop applications was the Page. Makerdesktop publishing software. IBM PS/2 series[edit]. AIX PS/2 running on Virtual PCAIX PS/2 (also known as AIX/3. Locus Computing Corporation under contract to IBM.[1. AIX PS/2, first released in 1. IBM PS/2personal computers with Intel 3. The product was announced in September 1. Extension package priced at $2. AIX were also sold separately in a Text Formatting System package priced at $2. The TCP/IP stack for AIX PS/2 retailed for another $3. The X Window package was priced at $1. C and FORTRAN compilers each had a price tag of $2.
