AIX is a series of proprietary Unix operating systems developed and sold by IBM for several of its computer platforms. Originally released for the IBM RT PC RISC workstation in 1986, AIX has supported a wide variety of hardware platforms, including the IBM RS/6000 series and later Power and PowerPC-based systems, IBM System i, System/370 mainframes, PS/2 personal computers, and the Apple Network Server. It is currently supported on IBM Power Systems alongside IBM i and Linux.
Digital Equipment Corporation, using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until forced to resign in 1992, after the company had gone into precipitous decline.
Alpha is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). Alpha was designed to replace 32-bit VAX complex instruction set computers (CISC) and to be a highly competitive RISC processor for Unix workstations and similar markets.
IRIX is a discontinued operating system developed by Silicon Graphics (SGI) to run on the company's proprietary MIPS workstations and servers. It is based on UNIX System V with BSD extensions. In IRIX, SGI originated the XFS file system and the industry-standard OpenGL graphics system.
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs.
Sun Microsystems, Inc. was an American technology company that sold computers, computer components, software, and information technology services and created the Java programming language, the Solaris operating system, ZFS, the Network File System (NFS), VirtualBox, and SPARC microprocessors. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing. Sun was founded on February 24, 1982. At its height, the Sun headquarters were in Santa Clara, California, on the former west campus of the Agnews Developmental Center.
The Single UNIX Specification (SUS) is the collective name of a family of standards for computer operating systems, compliance with which is required to qualify for using the "UNIX" trademark. The core specifications of the SUS are developed and maintained by the Austin Group, which is a joint working group of IEEE, ISO JTC 1 SC22 and The Open Group. If an operating system is submitted to The Open Group for certification, and passes conformance tests, then it is deemed to be compliant with a UNIX standard such as UNIX 98 or UNIX 03.
OpenVMS, often referred to as just VMS, is a multi-user, multiprocessing and virtual memory-based operating system. It is designed to support time-sharing, batch processing, transaction processing and workstation applications. Customers using OpenVMS include banks and financial services, hospitals and healthcare, telecommunications operators, network information services, and industrial manufacturers. During the 1990s and 2000s, there were approximately half a million VMS systems in operation worldwide.
Tru64 UNIX is a discontinued 64-bit UNIX operating system for the Alpha instruction set architecture (ISA), currently owned by Hewlett-Packard (HP). Previously, Tru64 UNIX was a product of Compaq, and before that, Digital Equipment Corporation (DEC), where it was known as Digital UNIX.
Kylin is an operating system developed by academics at the National University of Defense Technology in the People's Republic of China since 2001. It is named after the mythical beast qilin. The first versions were based on FreeBSD and were intended for use by the Chinese military and other government organizations. With version 3.0 Kylin became Linux-based, and there is a version called NeoKylin which was announced in 2010.
The Santa Cruz Operation, Inc. was an American software company, based in Santa Cruz, California, that was best known for selling three Unix operating system variants for Intel x86 processors: Xenix, SCO UNIX, and UnixWare.
UnixWare is a Unix operating system. It was originally released by Univel, a jointly owned venture of AT&T's Unix System Laboratories (USL) and Novell. It was then taken over by Novell. Via Santa Cruz Operation (SCO), it went on to Caldera Systems, Caldera International, and The SCO Group before it was sold to UnXis. UnixWare is typically deployed as a server rather than a desktop. Binary distributions of UnixWare are available for x86 architecture computers. UnixWare is primarily marketed as a server operating system.
Unix System V is one of the first commercial versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as Unix System Unification, which solicited the collaboration of the major Unix vendors. It was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV.
AdvFS, also known as Tru64 UNIX Advanced File System, is a file system developed in the late 1980s to mid-1990s by Digital Equipment Corporation for their OSF/1 version of the Unix operating system. In June 2008, it was released as free software under the GPL-2.0-only license. AdvFS has been used in high-availability systems where fast recovery from downtime is essential.
AlphaStation is the name given to a series of computer workstations, produced from 1994 onwards by Digital Equipment Corporation, and later by Compaq and HP. As the name suggests, the AlphaStations were based on the DEC Alpha 64-bit microprocessor. Supported operating systems for AlphaStations comprise Tru64 UNIX, OpenVMS and Windows NT. Most of these workstations can also run various versions of Linux and BSD operating systems.
AlphaServer is the name given to a series of server computers, produced from 1994 onwards by Digital Equipment Corporation, and later by Compaq and HP. As the name suggests, the AlphaServers were based on the DEC Alpha 64-bit microprocessor. Supported operating systems for AlphaServers are Tru64 UNIX, OpenVMS, MEDITECH MAGIC and Windows NT, while enthusiasts have provided alternative operating systems such as Linux, NetBSD, OpenBSD and FreeBSD.
Veritas Enterprise Vault (EV) is an enterprise information archive platform developed by Veritas Technologies. It is part of the company's "Information Governance" suite. Enterprise Vault has the ability to archive from various sources such as Microsoft Exchange, SMTP (any), IBM Domino, Microsoft SharePoint and various File Systems with the ability to store on a multiple of storage platforms, such as NTFS, NetApp, Centera, SMB and WORM. The data archived is indexed, classified, de-duplicated and securely stored.
Locus Computing Corporation was formed in 1982 by Gerald J. Popek, Charles S. Kline and Gregory I. Thiel to commercialize the technologies developed for the LOCUS distributed operating system at UCLA. Locus was notable for commercializing single-system image software and producing the Merge package which allowed the use of DOS and Windows 3.1 software on Unix systems.
