History

Sine Nomine Associates began a project to bring OpenSolaris to the IBM mainframe in July, 2006.[1] Less than a year later, in April, 2007, Sine Nomine presented an initial progress report at IBM's System z Technical Expo conference.

At the Gartner Data Center Conference in Las Vegas, Nevada in late 2007, Sine Nomine demonstrated OpenSolaris running on IBM System z under z/VM. It was there that David Boyes of Sine Nomine stated that OpenSolaris for System z would be available "soon."[2]

At the SHARE conference on August 13, 2008, Neale Ferguson of Sine Nomine Associates presented an update on the progress of OpenSolaris for System z. This presentation included a working demonstration of OpenSolaris for System z. During this presentation he stated that while OpenSolaris is "not ready for prime-time" they do hope to have a version available to the public for testing "in a matter of weeks rather than months."[3]

In October, 2008, Sine Nomine Associates released the first "prototype" (it lacks a number of features such as DTrace and Solaris Containers) of OpenSolaris for System z to the public.[4] OpenSolaris for System z has a project page at OpenSolaris.org.[5] OpenSolaris for System z is freely available for download at no charge and is governed by the same open source license terms as OpenSolaris for other platforms. All source code is available; there are no OCO (object code only) modules.

The port uses z/Architecture 64-bit addressing and therefore requires an IBM System z mainframe. Because the port uses certain advanced processor instructions, it requires a System z9 mainframe (or higher model) and will not run on older machines, at least not as currently compiled. It also requires the paravirtualization features provided by z/VM; it will not run on "bare metal" or in a logical partition (LPAR) without the z/VM hypervisor at Version 5.3 level or later.[6] On November 18, 2008, IBM authorized the use of IFL processors to run OpenSolaris for System z workloads.[7]
