== OpenZFS launches today, September 17th 2013; read the [[announcement]]! ==


The OpenZFS project is the truly '''open source''' successor to the [[History | ZFS project]]. Our community '''brings together developers''' from the illumos, FreeBSD, Linux, and OS X [[distributions | platforms]], and a wide range of [[companies]] that are building products on top of OpenZFS.
== [[OpenZFS Developer Summit 2023]] ==


OpenZFS is an '''outstanding storage platform''' that encompasses the functionality of traditional filesystems, volume managers, and more, with consistent reliability, functionality and performance across all [[distributions]].
The eleventh annual OpenZFS Developer Summit was held in San Francisco '''Oct 16-17 (Mon-Tue), 2023'''.

The high-level goals of the OpenZFS project are:
[https://openzfs.github.io/openzfs-docs/man/index.html OpenZFS manual pages]
* to '''raise awareness''' of the quality, utility, and availability of open source implementations of ZFS
* to encourage '''open communication''' about ongoing efforts to improve open source ZFS
* to ensure '''consistent reliability''', functionality, and performance of all distributions of ZFS.


The main technical goal of the project is '''easier sharing of code''' between platforms. Strategies include:
Feature Details. Detailed subsystem/feature blogs, on-disk format specifications: [[Developer_resources | Developer Resources]]
* creating a platform-independent [[mailing list]] for developers to review ZFS code and architecture changes from all platforms
* smoothing the [[illumos integration process]]
* making it easy to run both ztest and the ZFS test suite (TestRunner or STF based) on each platform
* [[Reduce code differences | reducing code differences]] between the platforms.
