The premise was kinda dumb, wouldn't be surprised if its just a scam.

So many people want to believe in this sort of thing for various reasons that I get fatigued at the very thought of trying to explain to people who believe in it earnestly that it is not a good idea. (e.g. commercial hosting services are really competitive; for a long time the cost of computing has been going down over time though I don't know if that is reversing because we've hit the end of the real Moore's law [1] or if it is a temporary blip)

[1] the motor behind it is cost reduction, once that stops it stops because we can't afford it anymore!

Well, it exists, but it exists if you’re willing to buy server hardware on eBay, hustle to get old parts working together, negotiate a good deal on a cabinet, get space from ARIN and announce it and so on. There are probably 10-50x cost efficiencies vs. renting 5 year old CPU families on AWS at huge markup.

A laptop isn’t the way to do that though. And your typical VC-fueled startup isn’t going to know how to do it either. It takes a very narrow slice of competence to be able to do that correctly.

the one guy I know who has worked with colo at scale (unfortunately in the crypto space) is now an EM at Goog

More likely a prank.

I would like to put my Raspberry Pi Pico in colocation, would it work?

There are a number of places that colocate normal Raspberry Pi.

I am sure that some of them either already colocate Pico ones too, or are willing to do so if asked.

The Pi Pico doesn't have networking capabilities, so that would be silly. You're probably thinking of the Pi Zero.

There is a Pico W

I think it's most likely testing the waters for a real offering. It's not that weird. Many colo data centers already have policies about hosting laptops because it's already something that happens. It just isn't common and usually isn't for hosting servers.

If the battery in the laptop is still good, it comes with it's own UPS. My MBPs haven't had an ethernet port in a minute, so do you have to supply your own adapters as well??? You could fit ~15 MBPs on their edge in 9RUs. That'd be an interesting looking rack. Not quite a blade chassis. It'd be rather boring looking as there's no blinky-blinkies

Putting a UPS in a rack is a prosumer/corporate IT thing, it’s not done in real datacenters.

They typically have their own UPS in another room and multiple power lanes. And it’s going to be much more reliable than a laptop battery.

I didn't really think that any of what I wrote would be taken seriously to the point of needing a retort. I mentioned blade servers and knew rack unit measurements which as context clues would have suggested I was familiar with actual data center equipment.

I read the reply to your comment not as much as an answer to your statement but a general warning to anyone who might be reading.

A laptop battery would be a huge liability if it caught fire.

And yet most homes and offices are full of them. Laptop batteries don't usually catch fire. At the colos I am familiar with (which have pretty strict rules, generally), you can have equipment with batteries as long as you regularly inspect them.

If you got creative with cable management you might be able to double up front and rear. It would probably be a PITA to manage but you could probably get some halfway decent density

Looks like they were proposing supplying usb Ethernet adapters, which doesn’t seem crazy, they’re cheap.

> You could fit ~15 MBPs

15 MBP x €7 = €105 for 9RU with power and network. Not in a million years.

Hetzner rents you 42RU for €199 plus power and network. If we assume they can fill the entire rack, that's 4 9RU units for about €50 plus power and network.

If we assume an average power draw of 20W per laptop, that's 300W for each 15 laptop unit, or about €57/month in Hetzner's Finish DC (including aircon)

Not sure about network. A 1Gbit uplink with 10TB traffic (and €1/TB after that) is provided. Upgrading that to 10Gbit is probably similar to the €51/month cost for the same uplink for dedicated servers, so another €15 for each 15 laptop unit. Plus around €2/month/IP, but you can probably bring your own if you find a cheaper subnet to buy

So yeah, you are right that the math does not work out. But it is pretty close to break even. I think you can break even on this if you find a more space efficient way to cram them into the rack and don't pay yourself any salary

The title says PoC, so I presume it's a PoC.
