What is OpenIndiana?
OpenIndiana is a robust enterprise operating system, based on the illumos kernel. It is open source, free to use, community developed, and suitable for servers and desktops.
It forked from OpenSolaris after the discontinuation of that project by Oracle and aims to continue development and distribution of the OpenSolaris codebase.
OpenIndiana is available for 32- and 64-bit x86 systems.
