From what I can tell this isn't going to function, mainly just due to the additional proprietary connectors on that Dell card. I imagine there's some sort of firmware integration as well though since it's got a data line coming off it too. Quick side question, is there any reason you're not just picking up some N95 boxes off Amazon? They're so cheap you'd pay for them in power savings vs this box alone and you could essentially treat it as a Raid 1 of the entire system with a handful of backup scripts.
Thanks for your time and consideration. I planned a few different builds with an N100, but everything priced out way more than I wanted to spend, even without drives. I saw this server for $80 on FB marketplace, and that was that.
RAID1 is only for the Proxmox installation, them I will use ZFS for the block storage.
