OpenSolaris for System z

OpenSolaris for System z is a distribution of the OpenSolaris operating system designed to run on the IBM System z mainframe computer.

In late October of 2008, Sine Nomine Associates released a running proof-of-concept port of OpenSolaris for System z processors, in collaboration with Sun Microsystems, and with IBM providing technical assistance and equipment to facilitate the port. The latest release, Build 100, updated 30 March 2009, is available for free download on the SNA website:

There are three packaging choices: VMARC, AWSTAPE, and a DVD image. All three images contain identical code, and they can be used with the installation instructions provided in the package and on the web page. The images are authorized to run on standard engines or (as of the IBM announcement of November 18, 2008) on IFL processors. Documentation is provided in the VMARC files in plain text, PDF, and Bookmaster/READ format.
