Goal:
- 16TB mirrored on 2 drives (raid 1)
- Hardware raid?
- Immich, Jellyfin and Nextcloud. (All docker)
- N100, 8+ GB RAM
- 500gb boot drive ssd
- 4 HDD bays, start with using 2
Questions:
- Which os?
- My though was to use hardware raid, and just set that up for the 2 hdds, then boot off an ssd with Debian (very familiar, and use it for current server which has 30+ docker containers. Basically I like and am good at docker so would like to stick to Debian+docker. But if hardware raid isn’t the best option for HDDs now a days, I’ll learn the better thing)
- Which drives? Renewed or refurb are half the cost, so should I buy extra used ones, and just be ready to swap when the fail?
- Which motherboard?
- Which case?
I’ve had a great experience with the TrueNAS Mini-X system I bought. ZFS has great raid options, and TrueNAS makes managing a system really easy. You can get a box built & configured by them, with 16 GB ECC RAM and five (empty) drive bays, for about $1150 at the most affordable end. https://www.truenas.com/truenas-mini/
One thing to be careful about: you can’t add drives to a ZFS vdev once it’s been created, but you can add new vdevs to an existing pool. So, you can start with two mirrored drives, then add another two mirrored drives to that pool later.
(A vdev is a sub-unit of a ZFS storage pool, and you have to choose your RAID topology for each vdev and then compose those into a storage pool)
If it’s a raidz, you can.
ZFS vdev expansion is a thing that will probably be added to the next ZFS release.
Ofc it is not released yet, so i would not recommend designing a system for it for the near future.
