[Help] My first serious self hosted server (sh.itjust.works)

Hello, I managed to get my hands on a second hand Proliant HPE server that I want to turn into a media server for myself (possibly family too).

I also have a bunch of drivers lying around in all different sizes. I want a good balance of security, backup and flexibility for the future. So hear my plan out:

Running Ubuntu server LTS on SAS 600gb disks (now it's in raid5 array with 3 identical disks but I probably want to change that and take out some disks from it for my data)
hardware raid 0 on the various single disks (with HPE smart array)
mergerfs and snapraid for a "raid" and backup (I read some information about it and I think for my use is the best option)
Headscale VPN (basically Foss tailscale implementation) for remote connection and mesh network
Docker with all apps

I'm no expert on servers or RAIDs or HPE. What do you think? I'm mostly worried about the hardware raid 0 + Snapraid, is it doable?

Well fuck me now I’m scared. So, for him the problem is hardware raid?

It all depends on the greed of the campaign. I worked in a campaign where it was considered normal to keep a degraded raid without repair. Of course, data loss is a normal story in such companies. The raid guarantees data security only when one disk is being pulled (except for some raids), so it also needs to be monitored and replaced. On the other hand, with proper operation, you probably won't lose any data.

P.S. RAID0 - raid that can't be restored when degraded any disk in RAID. This is exactly worse choice for data save. STRIPE also writes blocks one at a time to the first disk and to the second, so that you would definitely lose exactly 50% of data blocks. Best choice raid10 for performance and raid5 if you need save money.
