It's a timely article as I'm looking at HC530's (WUH721414ALE6L4 / WUH721414ALN6L4 (wiredzone carries it)) for a home FreeNAS box:
- any relatively-modern enterprise 4U 3.5" storage box with Xeon 4 cores or so
- quieter, high-volume fan mod
- RAM: 64-128 GiB, beyond that isn't useful unless deduping
- NIC: X710-T4L 4x 10GbE copper NIC
- ZIL: mirrored pair of high-endurance, write-intensive, reliable SSD like Optane 900p/905p 280-480GB
- L2ARC: striped pair of read-intensive/larger SSDs like the Gigabyte Aorus Gen4 1 TB
This will fit nicely as my home NAS for a water-cooled dual EPYC virtualized server/workstation build underway. I managed to get a single water block with (3) G1/4 connections that will cool both CPUs and the VRM chokes/converters.
If anyone has better suggestions, please chime in.
