![]() The lawsuits were ended in 2010 with an undisclosed settlement. ![]() Sun counter-sued in October the same year claiming the opposite. In September 2007, NetApp sued Sun claiming that ZFS infringed some of NetApp's patents on Write Anywhere File Layout. A ZFS file system can store up to 256 quadrillion zettabytes (ZB). The name at one point was said to stand for "Zettabyte File System", but by 2006 was no longer considered to be an abbreviation. During the next 5 years (2006 to 2010), Sun frequently updated ZFS with new features, and ZFS was ported to Linux, Mac OS X (continued as MacZFS) and FreeBSD, under this open source license. In Solaris 10 6/06 ("U2"), Sun added the ZFS file system. Sun was an early proponent of open source software, and with OpenSolaris, Sun wanted to build a developer and user community around the software. In June 2005, Sun released most of the codebase under the CDDL license, and founded the OpenSolaris open-source project. Sun Microsystems was a strong proponent of open source software. Historically, Solaris was developed as proprietary software. ![]() In June 2006, Sun announced that ZFS was included in the mainstream 6/06 update to Solaris 10. Source code for ZFS was integrated into the main trunk of Solaris development on October 31, 2005, and released for developers as part of build 27 of OpenSolaris on November 16, 2005. It was announced on September 14, 2004, but development started in 2001. ZFS was designed and implemented by a team at Sun led by Jeff Bonwick, Bill Moore and Matthew Ahrens. x micro releases were retroactively named Solaris 1). The project was released under the name Solaris, which became the successor to SunOS 4 (although SunOS 4.1. This became Unix System V Release 4 (SVR4). ![]() In 1987, AT&T Corporation and Sun announced that they were collaborating on a project to merge the most popular Unix variants on the market at that time: Berkeley Software Distribution, UNIX System V, and Xenix. As of 2018, there are two main implementations of ZFS, both quite similar: Oracle's implementation, which is closed source and part of Solaris, and OpenZFS, which is widely used to provide ZFS on many unix-like operating systems.ฤก. illumos remains very closely involved with OpenZFS. In 2013 the co-ordination of open source ZFS moved to an umbrella organization, OpenZFS, which allowed any person or organization that wished to use the open source version of ZFS, to collaborate in developing and maintaining a single common version of ZFS. In 2010, the illumos project forked a recent version of OpenSolaris, to continue its development as an open source project, including ZFS. During 2005 - 2010, the open source version of ZFS was ported to Linux, Mac OS X (continued as MacZFS) and FreeBSD. Large parts of Solaris - including ZFS - were published under an open source license as OpenSolaris for around 5 years from 2005, before being placed under a closed source license when Oracle Corporation acquired Sun in 2009/2010. ZFS began as part of the Sun Microsystems Solaris operating system in 2001. The history and implementations of ZFS covers the development of the ZFS file system. ![]()
