OpenZFS brings together developers and users from various open-source forks of the original ZFS on different platforms and we're always looking to grow our community. There are a multitude of ways to contribute to the project and contributors are happy to help newcomers. As we add diverse perspectives, our community becomes richer, and we're committed to creating an environment where all people feel welcome.  [[Newcomers | Information for new contributors is available here.]]

== Overview ==
 
OpenZFS was [[announcement | announced in September 2013]] as the truly '''open source''' [[History | successor to the ZFS project]]. Our community '''brings together developers''' from the illumos, FreeBSD, Linux, macOS, NetBSD, and Windows [[distributions | 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]]:

We've decided to hold the event outside of San Francisco and use Delphix HQ in order to allow for the financial flexibility to transition to an online-only event if COVID-19 is still a significant concern as we get close to the event.

Introduction to OpenZFS

OpenZFS is an open-source storage platform. It includes the functionality of both traditional file systems and volume manager. It has many advanced features including:

  • Protection against data corruption. Integrity checking for both data and metadata.
  • Continuous integrity verification and automatic “self-healing” repair
    • 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
