: Set this to limit the maximum RAM ZFS can claim. For a dedicated storage node, leave this at 80–90% of RAM. For a hypervisor running bhyve virtual machines, limit ARC so the VMs have guaranteed memory.

Crucial setting for modern Advanced Format drives (set ashift=12 for 4k sectors).

Offers significantly higher compression ratios than LZ4 with modern CPU optimization. Use zstd (levels 1–3) for text repositories, logs, and general filesystems. Use higher levels only on archiving pools. Command Syntax: zfs set compression=zstd-3 mypool/logs Use code with caution.

The mastery of Advanced ZFS also involves a thorough understanding of the "vdev" (virtual device) topology and how it impacts both redundancy and expansion. The book guides the reader through the decision-making process of choosing between mirrors, RAID-Z configurations, and dRAID, highlighting the trade-offs of each approach. It also touches on modern features like native encryption and device removal, which have traditionally been pain points for ZFS users.

Modern OpenZFS allows the removal of top-level single or mirrored VDEVs from a pool, copying data to remaining VDEVs via an internal mapping table. Note that RaidZ VDEVs cannot be removed this way. Data Allocation: Metaslabs and Space Maps For a dedicated storage node, leave this at 80–90% of RAM
