Platform
ZFS best practice: do not fill pools beyond 80 %. Higher values reduce the displayed effective capacity.
A second, capacity-matched system at another site as the replication target — a recommendation appears on the right.
Drives
Reduce the count/hot-spares or add an expansion shelf (section below).
