An ARM based server almost sounds like an oxymoron.

Heh, the fastest HPC cluster on the top 500 list is arm.

Amusingly #2, #3, and #4 aren't x86-64 either. Number 5 is, but mainly because the xeons are handling I/O for the real heavy lifting on the matrix-2000 accelerators. The first pure x86-64 cluster is #8.

So the performance story is changing quickly, and arm is just getting started.

Used Lenovo Tiny M92p/M93p units make a nicer solution for this, to me. The enclosure is already there, and no janky USB storage to deal with.

A Lenovo M92p is about 6x the price of a RPi, and the noise/form factor can't possibly be compared. If you really want to compare a 200$ desktop with a 40$ SoC then you should aim for stuff such as those mini PC's/thin clients from Asus, which nowadays even ship with Ryzen processors.

Lenovo regularly tries to fill ThinkCenter Tiny quotas by orders at the costs for their internal reasons. That’s what he’s talking about.

For the purpose of home server, SFF PCs are enough small to put on side of the router and almost zero noise. It a bit costs but it features decent storage, great CPU, reliable LAN. Even x6, $200 is cheap.

Unless you specifically need the 8GB RAM (where Rpi 4 is the only contender in this range as of right now AFAIK), IMO for server use-cases it'd be better to consider either Odroid C4 or Rock Pi 4 - both offer better storage interfaces than USB/microSD natively. Also easier to run vanilla Debian/Ubuntu (or Armbian, which is very close to vanilla but can be easily built custom for either board preconfigured with necess…

I have many pis, but when it comes to making a mini server, wouldn't it be worth it to spring for a low end intel machine, or used mini-pcs? They already come with things like power supplies, RTC+battery, on-off switches, sata and/or m.2, expandable memory, etc.

A lot of skepticism in this thread. I've got a pi4 4GB running Ubuntu server, acting as a SMB file server, Plex media server, Mopidy music server, Spotify Connect endpoint, video recorder for my two outdoor IP cameras, and a Minecraft server for my kids, all running simultaneously. And it's not breaking a sweat, not even getting close to full memory or CPU utilization. I do use a USB nvme SSD enclosure for storage to…

I'm running my rpi 4 as a kubernetes controller on Ubuntu. It also has wireguard hooked up with 8 dedicated server nodes. The SD card class A2 has been enough for disk performance, no SSD needed.

It's mounted on a din rail with the DINr mount plate and a Poe hat, makes it very compact and it fits in my small fiber network clauset. Planning to add 2 more for hight availability.

Can it idle at 1W? I'll be running the server all the time, so every watt counts.

Earlier quoted context omitted.

I don't see where it makes any sense to compare an ancient used end-of-life x86 laptop with a brand new ARM SoC in any of the relevant categories, such as price, form factor, power consumption, availability, and even support. Just for context, you can fit about 10 raspberry pi 4s in the same volume you fit your used laptop, and for the price of an old end-of-life Thinkpad you can buy 5 or 6 RPis. Hell, you can go to…

What do I care how many Raspberry Pis I can fit in the same space as a used Thinkpad which brings a display, keyboard, battery backup, and myriad high-speed IO ports beyond just USB, when we're talking about a stationary server role? I'm going to go out on a limb and assume the average HNer already has numerous retired laptops collecting dust in a corner, all more powerful and better suited to connecting high-speed s…

Every pi sold feeds starving people with lifesaving pie.

I got a Raspberry Pi 4 and naively thought that because it was ARM it used little power and didn't need fans. In a few weeks the board melted and now won't turn on. Was only running a few programs.
