== Summary ==
== [[OpenZFS Developer Summit 2023]] ==


OpenZFS was [[announcement | announced in September 2013]] as 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 build products on top of OpenZFS.  
The eleventh annual OpenZFS Developer Summit was held in San Francisco '''Oct 16-17 (Mon-Tue), 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 high-level goals of OpenZFS are:
Feature Details.  Detailed subsystem/feature blogs, on-disk format specifications: [[Developer_resources | Developer Resources]]
* 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 OpenZFS is '''easier sharing of code''' between platforms. Strategies include:
* 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.
