• ZFS on disk encryption support
  

Welcome to ZFS

ZFS is a new kind of file system that provides simple administration, transactional semantics, end-to-end data integrity, and immense scalability. ZFS is not an incremental improvement to existing technology; it is a fundamentally new approach to data management. We've blown away 20 years of obsolete assumptions, eliminated complexity at the source, and created a storage system that's actually a pleasure to use.

ZFS Features

• Pooled Storage Model
• Always consistent on disk
• Protection from data corruption
• Live data scrubbing
• Instantaneous snapshots and clones
• Fast native backup and restore
• Highly scalable
• Built in compression
• Simplified administration model

For a more detailed look at these features, and more, check out What is ZFS? page.

ZFS is available in build 27a of OpenSolaris and Solaris Express: Community edition. See the downloads page for more information.

If you don't have Solaris installed but want to see ZFS in action, check out Dan Price's screencasts covering ZFS basics as well as Self Healing features. See the Getting Started page for a brief overview of most of the command line features.

Once you've downloaded and started using ZFS, you should head over to the Documentation page for more detailed information. You may also want to peruse the various ZFS blogs available, which touch on a wide variety of subjects at many different levels.

Finally, if you're a developer, you may want to visit the Source Code Tour for a detailed look at the nuts and bolts of ZFS.

作为 I/O 调度的一部分，ZFS 有一个字段叫 'zfs_vdev_max_pending'。该字段限制了在 每个页虚拟设备 (vdev) 中我们可以向下发送的 I/O 的最大数量。这并不是每个文件系统或每个池的最大量。当前默认值为 35。对于现在的硬盘驱动器来说，这个数字已经很不错了，但是，对于那些实际上由很多的硬盘组成却作为一个单独设备输出到 ZFS 的存储阵列来说，这显然不够。 如果您的 ...
