Zettabyte FileSystem
ZFS (Zettabyte FileSystem) is a file system designed by Sun
Microsystems for the Solaris Operating System. ZFS is a 128-bit file system, so
it can address 18 billion billion times more data than the 64-bit systems ZFS
is implemented as open-source filesystem, licensed under the Common Development
and Distribution License (CDDL).
The features of ZFS include support for high storage capacities, integration of the concepts of file system and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, RAID-Z etc. Additionally, Solaris ZFS implements intelligent prefetch, performing read ahead for sequential data streaming, and can adapt its read behavior on the fly for more complex access patterns. To eliminate bottlenecks and increase the speed of both reads and writes, ZFS stripes data across all available storage devices, balancing I/O and maximizing throughput. And, as disks are added to the storage pool, Solaris ZFS immediately begins to allocate blocks from those devices, increasing effective bandwidth as each device is added. This means system administrators no longer need to monitor storage devices to see if they are causing I/O bottlenecks.
