For business-critical server deployments, Snow Leopard Server adds read and write support for the high-performance, 128-bit ZFS file system, which includes advanced features such as storage pooling, data redundancy, automatic error correction, dynamic volume expansion, and snapshots.
The apple page is all marketing, so see wiki or Sun's page for zfs info. A 128-bit zfs system is inconceivably large
|If a billion computers each filled a billion individual file systems per second, the time required to reach the limit of the overall system would be almost one thousand times the estimated age of the universe.|
|Project leader Bonwick said, "Populating 128-bit file systems would exceed the quantum limits of earth-based storage. You couldn't fill a 128-bit storage pool without boiling the oceans."|
