Tru64 UNIX


(Other UNIX and UNIX-like implementations built on top of the Mach kernel are GNU Hurd, NeXTSTEP, MkLinux, macOS and Apple iOS.) Tru64 UNIX required the SRM boot firmware found on Alpha-based computer systems. == DEC OSF/1 AXP == In 1988, Digital Equipment Corporation (DEC) joined with IBM, Hewlett-Packard, and others to form the Open Software Foundation (OSF).


After DEC's first release (OSF/1 Release 1.0) in January 1992 for their line of MIPS-based DECstation workstations, DEC ported OSF/1 to their new Alpha AXP platform (as DEC OSF/1 AXP), and this was the first version (Release 1.2) of what is most commonly referred to as OSF/1.


DEC OSF/1 AXP Release 1.2 was shipped on March 1993.


It was released in 1999. == TruCluster Server == From release V5.0 Tru64 UNIX offered a clustering facility named TruCluster Server.


Each member had one or zero votes, which, combined with a possible quorum disk, implemented a cluster formation algorithm similar to that found in OpenVMS. ==End of Life == With their purchase of Compaq in 2002, HP announced their intention to migrate many of Tru64 UNIX's more innovative features (including its AdvFS, TruCluster, and LSM) to HP-UX.


In December 2004, HP announced a change of plan: they would instead use the Veritas File System and abandon the Tru64 advanced features.
