OpenSolaris is an open source operating system based on Sun Microsystems' Solaris. It is also the name of the project initiated by Sun to build a developer and user community around it.
OpenSolaris is derived from the Unix System V Release 4 codebase, with significant modifications made by Sun since it bought the rights to that code in 1994. It is the only open source System V derivative available.[1] Open sourced components are snapshots of the latest Solaris release under development.[2] Sun has announced that future versions of its commercial Solaris operating system will be based on technology from the OpenSolaris project.[3]

[edit] History
OpenSolaris is based on Solaris, which was originally released by Sun in 1991. Solaris is a version of SVR4 (System V Release 4) UNIX, co-developed by Sun and AT&T. It was licensed by Sun from Novell to replace SunOS.[4]
Planning for OpenSolaris started in early 2004. A pilot program was formed in September 2004 with 18 non-Sun community members and ran for 9 months growing to 145 external participants.
The first part of the Solaris codebase to be open sourced was the Solaris Dynamic Tracing facility (commonly known as DTrace), a tracing tool for administrators and developers that aids in tuning a system for optimum performance and utilization. DTrace was released on January 25, 2005. At that time, Sun also launched the opensolaris.org web site, and announced that the OpenSolaris code base would be released under the CDDL (Common Development and Distribution License). The bulk of the Solaris system code was released on June 14, 2005. There remains some system code that is not open sourced, and is available only as pre-compiled binary files.
A Community Advisory Board was announced on April 4, 2005: two were elected by the pilot community, two were employees appointed by Sun, and one was appointed from the broader free software community by Sun. The members were Roy Fielding, Al Hopper, Rich Teer, Casper Dik, and Simon Phipps. On February 10, 2006 Sun reestablished this body as the independent OpenSolaris Governing Board.[5]. The task of creating a governance document or "constitution" for this organization was given to the OGB and three invited members: Stephen Hahn and Keith Wesolowski (developers in Sun's Solaris organization) and Ben Rockwood (a prominent OpenSolaris community member).
On March 19, 2007, Sun announced that it had hired Ian Murdock, founder of Debian, to head "Project Indiana",[6] an effort to produce a complete OpenSolaris distribution, with GNOME and userland tools from GNU, plus a network-based package management system.[7] Several independent distributions are also available.
On May 5, 2008, OpenSolaris 2008.05 was released, in a format that could be booted as a Live CD or installed directly. It uses the GNOME desktop environment as the primary user interface. The release includes a GUI for ZFS' snapshotting capabilities, known as Time Slider, that provides functionality similar to Mac OS X's Time Machine.
In December 2008 Sun Microsystems and Toshiba America Information Systems announced plans to distribute Toshiba laptops pre-installed with OpenSolaris.[8][9]
On April 1, 2009, the Tecra® M10 and Portégé® R600 come preinstalled with OpenSolaris 2008.11 release and several supplemental software packages.[10][11]
On June 1, 2009, OpenSolaris 2009.06 was released, with support for the SPARC platform.[12]

[edit] Crossbow
With Crossbow, you can use OpenSolaris to deploy entire network architectures on one physical server.
[edit] Storage technologies
New innovations in storage technologies.
[edit] Virtualization
OpenSolaris 2009.06 can now run in a Xen environment as dom0 or domU on x86 platforms. The latest release also works on Logical Domains on SPARC platforms.
[edit] Enhanced Performance
Performance is significantly enhanced. According to Sun's internal tests, OpenSolaris 2009.06 delivers 35 percent better memory management, 22 percent better integer arithmetics and 18 percent better multi-thread scheduler management when compared to the latest Linux releases
[edit] New Support Services
OpenSolaris now has technical support services.
[edit] Versions
[edit] License
Sun has released most of the Solaris source code under the Common Development and Distribution License (CDDL), which is based on the Mozilla Public License (MPL) version 1.1. The CDDL was approved as an open source license by the Open Source Initiative (OSI) in January 2005. Files licensed under the CDDL can be combined with files licensed under other licenses, whether open source or proprietary.[13]
During Sun's announcement of Java's release under the GNU General Public License (GPL), Jonathan Schwartz and Rich Green both hinted at the possibility of releasing Solaris under the GPL, with Green saying he was "certainly not" averse to relicensing under the GPL.[14] When Schwartz pressed him (jokingly), Green said Sun would "take a very close look at it." In January 2007, eWeek reported that anonymous sources at Sun had told them OpenSolaris would be dual-licensed under CDDL and GPLv3.[15] Green responded in his blog the next day that the article was incorrect, saying that although Sun is giving "very serious consideration" to such a dual-licensing arrangement, it would be subject to agreement by the rest of the OpenSolaris community.[16]
[edit] Legal status
Judge Dale Kimball made a ruling on July 16, 2008 in the legal case SCO v. Novell which included these statements:
| “ | After entering into the 2003 Sun Agreement, Sun released an opensource version of its UNIX-based Solaris product, called "OpenSolaris." As its name suggests, OpenSolaris is based on Sun's Solaris operating system, which is in turn based on Novell's SVRX intellectual property. Absent the removal of the 1994 Sun Agreement's confidentiality restrictions, Sun would not have been licensed to publicly release the OpenSolaris source code
...In this case, Sun obtained the rights to opensource Solaris, and SCO received the revenue for granting such rights even though such rights remained with Novell. If the court were to declare that the contract was void and should be set aside, the court could not return the parties to the same position they were in prior to the 2003 Agreement. Sun has already received the benefits of the agreement and developed and marketed a product based on those benefits. There was also evidence at trial that OpenSolaris directly competed with Novell’s interest. The court, therefore, cannot merely void the contract.[17] |
