= Welcome to OpenZFS =

Summary
OpenZFS was announced in September 2013 as the truly open source successor to the  ZFS project. Our community brings together developers from the illumos, FreeBSD, Linux, and OS X platforms, and a wide range of companies that build products on top of OpenZFS.

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:

Automated Testing
Pull requests submitted to our GitHub page are automatically tested, by running ztest and the ZFS Test Suite. We use illumos VM's running on AWS to perform the tests, and results are available publicly.

Thanks to infrastructure sponsor Nexenta for covering our AWS hosting costs!

Goals
The high-level goals of OpenZFS are:
 * 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
 * reducing code differences between the platforms.

Donate
We accept donations to cover our ongoing costs.

OpenZFS is an associated project of SPI (Software in the Public Interest). SPI is a 501(c)3 nonprofit organization which handles our donations, finances, and legal holdings. You can donate through paypal using the link below:
