OpenZFS is open-source storage software which encompasses the functionality of traditional filesystems, volume managers, and more. Our community brings together developers from the illumos, FreeBSD, Linux, and MacOS [[platforms]], and a wide range of [[companies and organizations]].  By working together, we will continue making OpenZFS an outstanding storage platform, with consistent reliability, functionality and performance across all [[distributions]].

OpenZFS is the truly open source successor to the [http://en.wikipedia.org/wiki/ZFS ZFS] project originally developed by [http://en.wikipedia.org/wiki/Sun_Microsystems Sun Microsystems] for the Solaris operating system. The source code for ZFS was released under the [http://opensource.org/licenses/CDDL-1.0 CDDL] in 2005 as part of the [http://en.wikipedia.org/wiki/Opensolaris OpenSolaris] operating system, and was subsequently ported to other [[platforms]]:

* In 2006 the first alpha release of ZFS support on Linux [http://zfs-on-fuse.blogspot.com/ via FUSE] was released.
'''OpenZFS''' is an open-source storage platform. It includes the functionality of both traditional file systems and volume manager. It has many advanced [[Features | features]] including:
* In 2007 FreeBSD 7.0 included native support for ZFS.
* Protection against data corruption. Integrity checking for both data and metadata.
* In 2008 the ZFS on Linux  project began development of a native Linux port which had its first stable release in 2013.
* Continuous integrity verification and automatic “self-healing” repair
* The MacZFS project is porting ZFS to Mac OS.
** Data redundancy with mirroring, RAID-Z1/2/3 [and DRAID]
* Support for high storage capacities — up to 256 trillion yobibytes (2^128 bytes)
* Space-saving with transparent compression using LZ4, GZIP or ZSTD
* Hardware-accelerated native encryption
* Efficient storage with snapshots and copy-on-write clones
* Efficient local or remote replication — send only changed blocks with ZFS send and receive


After OpenSolaris was discontinued in 2010, updates to ZFS on Solaris were no longer released as open source. As a result, the illumos project was founded as an open source fork of OpenSolaris. OpenZFS development continues to thrive as a part of illumos which has added many new [[OpenZFS Features|features and performance improvements]]. All ports to other platforms now regularly pull in new OpenZFS features and fixes from illumos and vise versa.
