FreeBSD Mastery: Advanced ZFS by Michael W. Lucas and Allan Jude is the definitive follow-up to FreeBSD Mastery: ZFS Based on the book's tentative table of contents,

Best for database workloads (MySQL, PostgreSQL) requiring high random read/write IOPS. Resilver times are significantly faster than RAID-Z.

The ARC resides in the system RAM. You can view real-time ARC statistics using the FreeBSD-specific tool: zfsstat -A Use code with caution.

Explains advanced tuning techniques, including the use of special devices for metadata and optimizing ZFS cache mechanisms (ARC and L2ARC).

goes over the basics of ZFS volumes, which are block devices backed by ZFS. It delves into their common use cases and potential pitfalls.
