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's PoE?

[–] snekerpimp@lemmy.world 15 points 8 months ago

Power over Ethernet. Sorry, read it over three time for spelling, didn’t catch that I never gave the acronym meaning.

Path of Exile.

I can't believe someone downvoted you for asking about the acronym.

I get frustrated when the title, body, and comments all use an acronym, but I can't figure it out from context. Even more frustrating is when the linked article also doesn't explain it.

I think googling poe or poe computing will give you it

MINISFORUM S100-N100 launching later this year as efficient mini-PC with Power over Ethernet support

[–] chunkystyles@sopuli.xyz 1 points 8 months ago

I bought an N100 mini PC (not POE) as my new server a couple months ago. I really like it. That processor is great for power efficiency.

[–] jqubed@lemmy.world 4 points 8 months ago (2 children)

I actually didn’t know the Pi can do PoE; that gives me some ideas!

[–] NickwithaC@lemmy.world 15 points 8 months ago (1 children)

You need a hat for it.

[–] CraigeryTheKid@lemm.ee 8 points 8 months ago (1 children)

Ugh now even my Pi needs clothes??!? Ridiculous.

[–] ShortN0te@lemmy.ml 3 points 8 months ago

Yeah. Imagine, before you can get going with your project you even have to 'boot it up'. A real deal breaker.

[–] snekerpimp@lemmy.world 5 points 8 months ago

I have a cluster of four running all off a single switch, incredibly convenient.

[–] Deckweiss@lemmy.world 3 points 8 months ago (1 children)

Personally I am a fan of the soquartz blades

But I doubt one of those is more powerful than a pi. I run a cluster of them with k3s and distributed nvme storage, but that may not be useful for your particular needs.

[–] snekerpimp@lemmy.world 3 points 8 months ago (1 children)

I have three Raspberry Pi 4 4gb and 1 Pi 4 8gb at my disposal, and I still have moments where the thing I need to do will hiccup, or be slower than usual. The Pi 5 has been said to be two times as fast, which is plenty for me. just with the price all in of over $100, curious if anyone else has a better option/opinion

[–] Deckweiss@lemmy.world 2 points 8 months ago* (last edited 8 months ago) (1 children)

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.

[–] snekerpimp@lemmy.world 2 points 8 months ago (2 children)

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.

[–] Deckweiss@lemmy.world 2 points 8 months ago* (last edited 8 months ago)

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.

[–] AtariDump@lemmy.world 1 points 8 months ago (1 children)

… 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.

[–] BombOmOm@lemmy.world 1 points 8 months ago (1 children)

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.

[–] AtariDump@lemmy.world 2 points 8 months ago* (last edited 8 months ago) (1 children)

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.

[–] BombOmOm@lemmy.world 2 points 8 months ago* (last edited 8 months ago)

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

[–] BombOmOm@lemmy.world 2 points 8 months ago (1 children)

I would be interested in this as well. The Pi certainly works and I am running one POE. But the Pi can be very limiting.

If you are converting something, be aware PoE has a power budget of 15w and PoE+ has 30w. Though PoE++ can do 100w, I have not seen many switches with that.

[–] CurbsTickle@lemmy.world 4 points 8 months ago (1 children)

PoE++ is 60W, UPoE is 100W.

[–] Zeoic@lemmy.world 1 points 8 months ago

PoE++ Type 4 goes up to 100w, its Type 3 that goes to 60w. Why the hell they didnt just call it PoE+++ I'll never understand
