What is a Zpool?

What is so good about ZFS?

The advantages of using ZFS include: ZFS is built into the Oracle OS and offers an ample feature set and data services free of cost. Both ZFS is a free open source filesystem that can be expanded by adding hard drives to the data storage pool.

What does ZFS stand for?

Zettabyte File System
ZFS stands for Zettabyte File System and is a next generation file system originally developed by Sun Microsystems for building next generation NAS solutions with better security, reliability and performance.

Where is ZFS used?

ZFS was created at Sun Microsystems and open-sourced as part of OpenSolaris. It has since been ported to other OSes, including FreeBSD, Linux, and Mac OSX. If you want to know more about the origins of ZFS, ask Jeff Bonwick. ZFS is typically used on large storage servers and works well there.

What are the features of OpenZFS file system?

OpenZFS is an open-source storage platform. It includes the functionality of both traditional file systems and volume manager. It has many advanced features including: Protection against data corruption.

Which is the only operating system that supports ZFS?

Browse ZFS source code in GitHub or websvn. FreeNAS is a Network Attached Storage operating system. OSv is a new operating system designed for the cloud. It only runs virtualized, and the only file system it supports is ZFS. ZFS codebase forked from FreeBSD; but planning to move to OpenZFS upstream.

Which is the best compression algorithm for OpenZFS?

OpenZFS supports on-the-fly compression of all user data with a variety of compression algorithm. This feature adds support for the lz4 compression algorithm. lz4 is usually faster and compresses data better than lzjb, the old default OpenZFS compression algorithm.

What are the features of Solaris 11 OpenZFS?

Functionally identical to Solaris 11 extension zfs snap . OpenZFS introduces a -v option to zfs send which reports per-second information on how much data has been sent, how long it has taken, and how much data remains to be sent. Provides the ability to encrypt, decrypt, and authenticate protected datasets.
