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?
The distro isn’t likely to be a factor here. Any (non-super-specialized) distro will be able to solve issues in about the same way.
I mean, any recommendation is going to just be people mentioning their preferred distro.
I don’t know whether saltwater exposure is a concern. If so, that may impose some constraints on heat generation (if you have to have it and storage hardware in a waterproof case).
Yes, I think you’re right that distro doesn’t matter. As I’ve been reading through the responses, I realize that the two main issues are storage (don’t want to use HDDs on a bounching boat, but SSDs are expensive per TB) and power (limited battery and variable voltage). As you say, corrosion may also been an issue that I hadn’t considered. I’ll probably have to check in with the sailing forums to see if people have trouble with their laptops corroding at sea. This server isn’t likely to get splashed directly, but it will be exposed to a lot of humidity and variable temperatures.
