In addition to data integrity, device redundancy, and performance features, ZFS Storage Pools can also expanded in usable storage size through deduplication and compression of the data stored. In other words by shrinking raw data and removing duplicated parts of data, ZFS Storage Pools can store more data on disk. While there are some memory trade-offs using deduplication, it can provide significant storage savings for some types of stored data. There are also some significant performance benefits to compression.

In this article, we will explore how to configure deduplication and compression for storage pools.
