History

SCO UNIX was derived from AT&T System V Release 3.2 with an infusion of SCO Xenix device drivers and utilities. SCO UNIX System V/386 Release 3.2.0 was released in 1989 as the commercial successor to SCO Xenix. The base operating system did not include TCP/IP networking or X Window System graphics. Shortly after the release of this bare OS, SCO shipped an integrated product under the name of SCO Open Desktop, or ODT. 1990 saw the release of SCO MPX, an add-on SMP package. Tarantella, Inc. ...

SCO purchased the UnixWare system and its System V Release 4 code base from Novell in 1995. SCO was eventually able to re-use some code from that version of UnixWare in later releases of OpenServer. Until Release 6, this came primarily in the compilation system and the UDI driver framework and the USB subsystem written to it.

SCO announced on August 2, 2000 that it would sell its Server Software and Services Divisions, as well as UnixWare and OpenServer technologies, to Caldera Systems, Inc.

The SCO Group continues development and maintenance of OpenServer. They currently continue to maintain the now obsoleted 5.0.x branch derived from 3.2v5.0.x; the most recent of these is 5.0.7.


The SCO Group, on June 22, 2005, released OpenServer 6.0, codenamed "Legend", which is the culmination of a multi-year multi-million dollar development effort and the first release in the new 6.0.x branch of releases. SCO OpenServer 6 is based upon the System V Release 5 UNIX kernel and features multi-threading application support for C, C++, and Java applications through the POSIX interface. OpenServer 6 features kernel-level threading (not found in 5.0.x), and is bundled with a wealth of open-source applications including Apache, Samba, MySQL, OpenSSH, Mozilla Firefox, KDE, and much more. It also has many other improvements over OpenServer 5 including incredibly improved SMP support supporting up to 32 x86-family processors on a single server, support for files over 1 terabyte on a partition (larger network files supported through NFSv3), greatly increased file system performance, up to 64GB of memory, backward-compatibility for applications developed for Xenix 286 onwards, and much more. OpenServer 6 is currently available from a number of third-party SCO resellers. The latest released version in the 6.0.x branch of OpenServer is currently 6.0.0.
