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.

timf - ZFS backups to USB mass storage ?

Sep 19, 9:38 AM

If something were available that, on plugging a USB disk into an OpenSolaris laptop, would automatically snapshot any filesystems you cared about, and would send incremental ZFS send-streams to that ...

relling - Space Maps from Space

Sep 18, 4:56 PM

Jeff Bonwick recently blogged about why ZFS uses space maps for keeping track of allocations. In my recent blog on looking at ZFS I teased you with a comment about the space map floating near the ...

realneel - ZFS ARC Statistics

Sep 18, 12:24 PM

ARC Statistics are exported via kstat(1M) ( CR 6510807 ) in Solaris 10 U4 and Solaris nevada (build 57+). A simple way to see them is to use kstat -m zfs . I wrote a simple perl script to print out ...

bonwick - Space Maps

Sep 14, 5:03 AM

Every filesystem must keep track of two basic things: where your data is, and where the free space is. In principle, keeping track of free space is not strictly necessary: every block is either ...

erickustarz - NCQ sata_max_queue_depth tunable

Sep 11, 10:18 PM

Previously , i did some analysis on NCQ in OpenSolaris. It turned out that to get good multi-stream sequential read performance, you had to disable NCQ via the tunable 'sata_func_enable'. Disabling ...
