IRIX is a computer operating system developed by Silicon Graphics, Inc. (SGI) to run natively on their 32- and 64-bit MIPS architecture workstations and servers. Based on UNIX System V with BSD extensions, it is capable of extremely long uptimes, and its XFS file system is regarded as one of the most advanced journaling file systems in the industry.citation needed
The current major version of IRIX is IRIX 6.5 which was released in May 1998. New minor versions of IRIX 6.5 were released every quarter until 2005; since then there have been four further minor releases. Through version 6.5.22, there were two branches of each release: a maintenance release (identified by an m suffix to the version number) that included only fixes to the original IRIX 6.5 code, and a feature release (with an f suffix) that included improvements and enhancements. An overlay upgrade from 6.5.x to the 6.5.22 maintenance release is available for free download, while version 6.5.23 and higher require an active Silicon Graphics support contract, despite only running on Silicon Graphics hardware.
