Home server on old android phones? (lemmy.zip)

Hey guys, since I got into hosting my own servers, any electronic device I see I wonder - can it become a server?

This is probably not a crazy and new idea with android phones, but I had to share it with you. If you don’t know, there’s this thing called postmarket OS, full linux experience on an android phone.

Of course, not all phones are supported, but a phone like Galaxy Note 9 is a great candidate - it supports LAN over usb, postmarket OS fully supports it (the Exinos version) and setting up a phone as a selfhosted server has it’s real perks. Pis got really expensive, not to mention they don’t have a built-in UPS (phones have batteries), they use slow SD cards, while phones have faster UFS memory, phones draw way less power.

What do you guys think? I will for sure get a used Galaxy Note 9 and explore this idea, and if all goes well, I might even buy more of them and create a cluster.

Completely depends on where you are too, my NAS uses ~30W, which means ~22kWh in 30 days, which translated into local electricity costs are 53SEK or $5.39.
It has enough CPU (Intel Celeron J4125) to run my production loads, RAID1 16TB drives and 18GB RAM so it successfully hosts DNS, DHCP, Jellyfin, Vikunja and network shares. And I get the knowledge that it is all local and under my control.

Makes sense! 30W is great for your system. My home server has an older 10Gbps NIC that uses an Aquantia AQC107 chip, which has poor support for ASPM and prevents the CPU from entering lower C states. I've been considering swapping it out for something newer (like an AQC113), I just need to work out whether it's actually worth it.

Mine used to cost $0 in electricity since I've got solar panels, but we've got two EVs now (my wife has a BMW iX and I've got an i4) so we're back to having to pay the electricity company again.
