An Introduction to ZFS
ZFS has become increasingly popular in recent years. ZFS on Linux (ZoL) has pushed the envelope and exposed many newcomers to the ZFS fold. iXsystems has adopted the newer codebase, now called OpenZFS, into its codebase for TrueNAS CORE. The purpose of this article is to help those of you who have heard about ZFS but have not yet had the opportunity to research it.
Our hope is that we leave you with a better understanding of how and why it works the way it does. Knowledge is key to the decision-making process, and we feel that ZFS is something worth considering for most organizations.
