After some uncertainty over the integration of the ZFS (Zettabyte File System) file system into Mac OS X, this is now expected to happen in around a years time. Apple is promising to offer ZFS in the next version of the server operating system. The next incarnation of Mac OS X was officially announced at Apple's WWDC developers conference under the code name Snow Leopard. The statements on ZFS remain pretty vague and do not make clear whether it will be possible to make ZFS partitions bootable.

ZFS is a component of OpenSolaris, an open source project sponsored by Sun Microsystems, and is available under a free licence. It aims to ensure that data on the storage medium is consistent at all times, to prevent data errors and to enable the creation of snapshots and clones at any time. It also includes a mechanism for data compression. ZFS uses 128-bit pointers throughout and can therefore save files up to 16 exabytes in size – 1 exabyte is 260 bytes. In a blog entry, Sun CEO Jonathan Schwartz emphasises ZFS' suitability for installations with many drives and announces support for solid state disks.
