When Sun Microsystems released the ZFS filesystem in 2004, they set out to remove all of the practical limits on filesystem storage, and to make the arcane details of storage management a thing of the past. ZFS is a 128-bit filesystem with – to name just a few features – copy-on-write transactional semantics, fast snapshots, and optional compression.

The most obvious benefit of ZFS is its simple administration. In ZFS, traditional tasks like formatting a disk or editing /etc/fstab are gone entirely, and building a mirrored or striped RAID can be accomplished with a one-line command that actually looks sensible, is easy to remember, and has interactive help. ZFS does for storage management what MySQL did for databases, and like MySQL, it's open source, as well. ZFS was first introduced in Solaris, but Linux ports are underway, Apple is shipping it in OS X 10.5, and it will be included in FreeBSD 7.

To appreciate what this might mean for MySQL, consider the problem of storage management under InnoDB:
