Good day, friends. Since catching the self-hosting bug, I’ve set up a couple of Proxmox home servers with a bunch of services I enjoy.
Now I’d like to set up a server and local network on my sailboat so I can self-host servarr, pihole, and other services while traveling. The tricky part is that everything on the boat is 12V and I would rather not use an inverter, if possible. Also, it needs to be ultra-low power so I can leave it on at all times and not to deplete my batteries too much.
Criteria:
- ultra-low power
- Small form factor
- runs on 12V
- 10 TB of storage plus ability to make full local backup
- Capable of hosting servarr, audiobookshelf, freshrss, etc. via docker
- HDMI output
- Full local mirror/backup of the entire file system, including the media library.
- We will have two laptops and two Android phones to access the server, so the server doesn’t need to run a desktop environment.
I’ll have a mobile wifi router and a cellular signal booster (or maybe Starlink eventually) for internet access. Since internet bandwidth will be limited and expensive while traveling, I don’t want to have to re-download a massive media llibrary if the storage media fail. Thus, I want the media library to be mirrored or fully backed up or synced locally.
What hardware and Linux distro would you use in this situation?
What hardware does not run on 12 V?
Define ultra low power. Given the 10 TB + mirror (why?) I assume at least 2 HDDs have to spin. So at least 20 W total? I mean they can spin down, but leaving the system on 24/7 seems a bit far fetched, even if it only consumes 1 watt (0.1 A load, 2.4 Ah per day).
Yeah, good point. Now that you mention it, there is no real reason to run the server 24/7 on the boat. Also, HDDs would not be happy with the amount of bouncing that small sailboats undergo while at sea.
