• ZFS on disk encryption support
  

Welcome to ZFS

ZFS is a new kind of file system that provides simple administration, transactional semantics, end-to-end data integrity, and immense scalability. ZFS is not an incremental improvement to existing technology; it is a fundamentally new approach to data management. We've blown away 20 years of obsolete assumptions, eliminated complexity at the source, and created a storage system that's actually a pleasure to use.

ZFS Features

• Pooled Storage Model
• Always consistent on disk
• Protection from data corruption
• Live data scrubbing
• Instantaneous snapshots and clones
• Fast native backup and restore
• Highly scalable
• Built in compression
• Simplified administration model

For a more detailed look at these features, and more, check out What is ZFS? page.

ZFS is available in build 27a of OpenSolaris and Solaris Express: Community edition. See the downloads page for more information.

If you don't have Solaris installed but want to see ZFS in action, check out Dan Price's screencasts covering ZFS basics as well as Self Healing features. See the Getting Started page for a brief overview of most of the command line features.

Once you've downloaded and started using ZFS, you should head over to the Documentation page for more detailed information. You may also want to peruse the various ZFS blogs available, which touch on a wide variety of subjects at many different levels.

Finally, if you're a developer, you may want to visit the Source Code Tour for a detailed look at the nuts and bolts of ZFS.
