== History ==

OpenSolaris is based on [[Solaris (operating system)|Solaris]], which was originally released by [[Sun Microsystems]] in 1991. Sun Microsystems released the bulk of the Solaris system source code in OpenSolaris on 14 June 2005, which made it possible for developers to create other OpenSolaris distributions. [[Sine Nomine Associates]] began a project to bring OpenSolaris to the IBM mainframe in July, 2006.<ref>[http://www.sinenomine.net/node/411 IBM Expresses Interest in OpenSolaris for System Z Project] {{webarchive|url=https://web.archive.org/web/20080513153008/http://sinenomine.net/node/411 |date=13 May 2008 }}</ref> The project was named ''Sirius'' (in analogy to the Polaris project to port OpenSolaris to PowerPC). 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."<ref>[httphttps://www.youtube.com/watch?v=Ma0XPN2z6Qc&feature=related Open Solaris on System Z demo part III], YouTube Video</ref>

At the [[SHARE (computing)|SHARE]] conference on 13 August 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 hoped to have a version available to the public for testing "in a matter of weeks rather than months."<ref name="Share2008">{{Cite journal |first = Neale |last = Ferguson |title = OpenSolaris on System z |year = 2008 |place___location = SHARE Summer 2008, San Jose, CA |postscript = <!--None--> }}</ref>

In October, 2008, Sine Nomine Associates released the first "prototype" (it lacks a number of features such as [[DTrace]], [[Solaris Containers]] and the ability to act as an [[Network File System (protocol)|NFS]] server) of OpenSolaris for System z to the public.<ref>{{cite web |url=http://mainframe.typepad.com/blog/2008/10/opensolaris-for.html |first=Timothy |last=Sipples |title=OpenSolaris for System z Now Available |date=2008-10-16 |accessdateaccess-date=2008-10-16}}</ref> OpenSolaris for System z has a project page at OpenSolaris.org.<ref>{{cite web |url=http://www.opensolaris.org/os/project/systemz/ |title=OpenSolaris Project: Systemz |accessdateaccess-date=2008-10-17 |url-status=dead |archive-url=https://web.archive.org/web/20120229132722/http://hub.opensolaris.org/bin/view/Project+systemz/WebHome |archive-date=29 February 2012 |df=dmy-all }}</ref> OpenSolaris for System z is 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 computers|mainframe]]. Because the port depends on recently defined z/Architecture processor instructions, it requires a [[System z9]] or later mainframe model and will not run on older machines. It also will not run on the release version of [[Hercules emulator|Hercules]] mainframe emulator, the needed changes are included in the SVN version 5470 of Hercules. 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. Also, because OpenSolaris uses a new network DIAGNOSE instruction, PTF VM64466 or VM64471 must be applied to z/VM to provide support for that instruction.<ref>{{cite web |url=http://www.sinenomine.net/opensolaris |title=OpenSolaris for System z |accessdateaccess-date=2008-10-16 |archive-date=14 November 2009 |archive-url=https://web.archive.org/web/20091114112451/http://www.sinenomine.net/opensolaris |url-status=dead }}</ref> On 18 November 2008, [[IBM]] authorized the use of [[Integrated Facility for Linux|IFL]] processors to run OpenSolaris for System z workloads.<ref>{{cite web |url=http://www-01.ibm.com/common/ssi/rep_ca/5/897/ENUS108-875/ENUS108-875.PDF |title=Integrated Facility for Linux (IFL) authorization is expanded to include the OpenSolaris operating system |date=2008-11-18 |accessdateaccess-date=2008-11-19 }}</ref>
