I’m happy to inform that the ZFS file system is now part of the FreeBSD operating system. ZFS is available in the HEAD branch and will be available in FreeBSD 7.0-RELEASE as an experimental feature.
ZFS is a new kind of filesystem 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.
