ZFS, or Zettabyte File System, was originally developed by Sun. It protects all files with 64-bit checksums to detect and fix data corruption and, as a 128-bit file system, can handle many orders of magnitude more space than current versions of Mac OS X, Windows and Linux.

According to [url=http://www.sun.com/2004-0914/feature/]Sun[/url], ZFS meets the needs of a file system for everything from desktops to data centers. Designed with the administrator in mind, ZFS is the only self-healing, self-managing general-purpose file system, it offers (per Sun):

° Simple administration: "ZFS automates and consolidates complicated storage administration concepts, reducing administrative overhead by 80 percent."

° Provable data integrity: "ZFS protects all data with 64-bit checksums that detect and correct silent data corruption."

° Unlimited scalability: "As the world's first 128-bit file system, ZFS offers 16 billion billion times the capacity of 32- or 64-bit systems."

° Blazing performance: "ZFS is based on a transactional object model that removes most of the traditional constraints on the order of issuing I/Os, which results in huge performance gains."
