PoE Single Board/Micro/Mini Computer/Server (lemmy.world)

I have an 8gb Raspberry Pi 4 that has been a workhorse for years. I keep it for my not intense but essential networking purposes, NetBoot.xyz, Homepage, etc., because I can run it over PoE (edit: Power over Ethernet), so it is always on as long as my network is up.

It is growing long in the tooth, and I find myself wanting to replace it with something a bit more capable. Looking at the 8gb Pi 5 at $80 plus another $30 for a PoE hat, I wonder if there is something out there that would be a better value for running PoE? Can you convert a micro pc over to PoE? Does anyone have any recommendations for computers that run off PoE or can be converted to PoE?

What things do you do that hiccup?

It honestly reallt depends whether your task is hindered by storage speed (sd card), io speed (lan + usb ports), single core speed or lack of threads/cache. It would be good to find out what the limiting resource is, to understand the best upgrade path.

Webpage loads are slow, especially images, netboot is a bit slow. I'm sure it's i/o bottleneck and that everything is running in docker containers. I could probably optimize things a bit better, I just don't have that kind of time for these projects, and getting an old dell micro would be faster than what I have. but they don't run on PoE+ that I know of.

… they don't run on PoE+…

They do not; the power requirement is too high. You’re not going to find a computer with a “desktop class” CPU that can be powered via PoE.

Laptop class CPUs can though. AMD Ryzen chips are useful all the way down to 15w. There is a post in this thread of a mini-PC with one and PoE. Real happy that exists.

Got that link? I just looked and don’t see anything in this post linking to a computer with a desktop class processor that will run on PoE.

Thisin! Links to a few min overview of a Ryzen based PoE mini-pc.

I think pi 5 might be pretty good for you.

If I am not mistaken, they improved the io A LOT in the pi 5.

Also, you might be able to use the old HAT, at least it worked with pi3 poe hats on pi4.
