ZFS is a file system designed by Sun Microsystems for the Solaris Operating System. The features of ZFS include support for high storage capacities, integration of the concepts of filesystem and volume management, snapshots and copy-on-write clones, on-line integrity checking and repair, and RAID-Z. ZFS is implemented as open-source software, licensed under the Common Development and Distribution License (CDDL).

ZFS 是一种新型的文件系统,它提供了简单的管理、事务语义、端对端数据完整性以及极大的可伸缩性。ZFS 并不是对现有技术的增量改进,而是数据管理领域的一种全新的方法。我们摒弃了 20 年来的过时假设、消除了源代码的复杂性,创建了一个真正易于使用的存储系统。
