My paranoia about bits slowly flipping has finally gotten the better of me, so I decided to build a ZFS NAS, and the path of least resistance led me to FreeNAS. It would see only light, home usage, ~2 users max, used as weekly backup and a central source for media such as movies and music. The build I came up with is:
The full plan is to use btrfs on my desktop, so I don't back-up corrupted data, and use one or more btrfs-formatted 4TB external drives that would serve as rotated monthly off-site backups of the entire NAS. That's also why I'm hesitant to have more than 4TB space - then the backup disks would also have to increase in number and/or size.
That's about it. So - will it FreeNAS? Thanks in advance :)
- Motherboard: Supermicro X11SSL-F
- CPU: INTEL Pentium G4400 - I would have preferred a Pentium G4560, but the motherboard requires BIOS version 2.0 for Kaby Lake support, and I found several posts from 2017 of how difficult it was to upgrade the BIOS before they were able to boot, with Supermicro demanding payment for an unlock key to enable BIOS updates through IPMI, and I'd really rather not deal with all that. If anyone knows if these boards ship with updated BIOS these days, I'd be very grateful. But how much would I even benefit from a G4400->G4560 upgrade? Lower power use, perhaps?
- RAM: 1x SUPERMICRO MEM-DR416L-CV01-EU26 16GB PC4-21300 DDR4 ECC
Compatible according to http://store.supermicro.com/validatedparts/result/?cat=29&q=MBD-X11SSL-F, and the models listed on the motherboard's page are unavailable in my country. - HDDs: 2x WD HDD Red 4TB (WD40EFRX) + 1x 3TB HDD whose brand I forgot (could be WD), currently in my desktop, in RAID-Z2. If I understand correctly, this should give me 3TB usable space, and when the 3TB disk fails/is replaced with a 4TB one, I'll have 4TB space? Would it be better to have the disks in RAID-1 instead? I realize then I couldn't expand the VDevice usable space by adding more disks - are there any other drawbacks to RAID-1 in this case?
- PSU: SEASONIC G-450 - if I ever want to expand to 5 HDDs.
- SSD: WD SSD Green SATA3 2,5" 120 GB (WDS120G2G0A) - to install FreeNAS on, and nothing more. Will it fit on the motherboard?
- Case: Old desktop midi-tower case.
- UPS: None so far. Honestly, I'd rather only use overvoltage protection. Power outages are very rare where I live, and I don't want to put more potentially flammable batteries in my home than I need to. Don't know about power spikes or how noisy the power is, though - I don't care about uptime/availability, but I do want to keep the hardware healthy for as long as possible.
