'''SINIX''' is a discontinued variant of the [[Software:Unix|Unix]] [[Operating system|operating system]] from Siemens Nixdorf Informationssysteme. SINIX supersedes SIRM OS and [[Company:Pyramid Technology|Pyramid Technology]]'s DC/OSx. Following X/Open's acceptance that its requirements for the use of the UNIX [[Social:Trademark|trademark]] were met, version 5.44 and subsequent releases were published as '''Reliant UNIX''' by [[Company:Fujitsu Siemens Computers|Fujitsu Siemens Computers]].

==Features==
In some versions of SINIX (5.2x) the user could emulate the behaviour of a number of different versions of Unix (known as ''[[Universe (Unix)|universe]]s''). These included System V.3, [[Software:UNIX System III|System III]] or [[Software:Berkeley Software Distribution|BSD]]. Each universe had its own command set, libraries and header files.

==Xenix-based SINIX==
The original SINIX was a modified version of [[Software:Xenix|Xenix]] and ran on [[Engineering:Intel 80186|Intel 80186]] [[Engineering:Microprocessor|processor]]s. For some years Siemens used the [[NS320xx|NSC-32x32]] (up to Sinix 5.2x) and Intel 80486 CPUs (Sinix 5.4x - non MIPS) in their MX-Series.

==System V-based SINIX==
Later versions of SINIX based on [[Software:UNIX System V|System V]] were designed for the:
* SNI RM-200, RM-300, RM-400 and RM-600 servers running on the [[MIPS architecture|MIPS]] processor (SINIX-N, SINIX-O, SINIX-P, SINIX-Y)
* SNI PC-MX2, MX300-05/-10/-15/-30, Siemens MX500-75/-85 running [[NS320xx]] (SINIX-H)
* PC-MXi, MX300-45 on the Intel [[X86]] processor (SINIX-L)
* SNI WX-200 and other IBM-compatible i386 PCs on the [[Engineering:Intel 80386|Intel 80386]] and newer processors (SINIX-Z)

The last release under the SINIX name was version 5.43 in 1995.

==Reliant UNIX==
The last Reliant UNIX versions were registered as [[Single UNIX Specification|UNIX 95]] compliant (XPG4 hard branding).

The last release of Reliant UNIX was version 5.45.
