I was part of the team that built this project at Scaleway, ask me anything

I'm part of the current team ! Ask me anything itrash doesn't know ;)

Good to see you :), there a lot of good questions ! I'm not working on the project anymore so you'll be able to reply with better answer. But still had a really good experience with you guys.

Scaleway's site and support is horrible, as you've found. But their pricing and offerings are solid and their network is... OK. For the price, they're better than Hetzner... if you can get signed up!

It was specifically for the M1 mac minis, so not too fussed about everything else, but judging from the comments, experiences are mixed. I'll try to sign up again in a week or two.

If you have further difficulties, give us a shout on our community slack : https://www.scaleway.com/en/docs/tutorials/scaleway-slack-co...

There's an #apple-silicon channel there that the team behind the product monitors

Continuing to act like these ugly hacks are a normal way of doing business, is a continual signal to Apple that they don't need to build a rack-mount PC or server ever again. If their developer community grew a pair and made themselves heard, then maybe the billion dollar company would do their effing job and provide a proper rackable development platform. Which they had many years ago, before they morphed into a com…

Also gotta love servers with non-ECC memory

https://www-uploads.scaleway.com/Mac_mini_rack_1_e31ad1da6e.... This is not the image I expected to encounter under the title, “high density”. Make those sleds taller and do three, maybe four per sled with a pair of large diameter fans. That’ll would be high density. This is medium at best.

The fan would move the heat off that given sled but if the channel between the sleds can’t remove that extra heat you probably didn’t help yourself. My point is the picture doesn’t show any details on the room or what’s outside the rack so it’s hard to know what’s optimal.

Fans generally are used to move cold air from in front of a rack behind the rack. There appear to be no fans at all here except those in the mini,which would cause the problem you discuss. I’m talking about supplemental cooling with a high volume low noise fan in a 2 or 3u enclosure.

For anyone reading along at home, 2 inches is just over 5cm.

Yeah sorry for mixing units like that. I think of it as a 19" rack and know that refers to the width, but I had to look up the height of a 4U chassis and Google told it to me in cm, so then I went with that for that dimension.

Totally fine, my brain just isn't used to processing imperial measurements in the same sentence as metric, so I thought the conversion might help others in the same place!

Why are they still even in the cases? I would assume that shucking them would ever so slightly improve thermals.

We were a little team, doing the API dev, the infra, the hardware and countless things. The product is improving and it was impossible to even imagine remoing the case as we spent so many time wiring everything, going to DC and setting up everything. Yes the team is actually doing all of this, even going to DC installing the macs in the racks. But I agree that for a big scale, this is a good solution. (cf: github)

Agree, removing the case is a lot of effort. Github does a lot of fancy things but you might want to consider how much they're charging by the minute as well

Our way is quite efficient & we're able to quickly adapt to new HW gens

Unlike the old rack mount options for the trashcan Mac Pro units (eg https://photos.imgix.com/racking-mac-pros ), it doesn't seem like much thought has been given here to a front-to-back airflow. I'm also surprised they're touting the density of this solution— seems like the obvious thing would be to put the Minis on their sides. A 4U chassis has 17.5cm vertical space in it, and a Mac Mini is 17cm wide. With the Mini…

> Each rack can hold up to 96 Mac minis,

Sounds like 2 per 1U to me. I think it's power efficiency that limits filling a rack with typical 1U servers in most plans. The power efficiency here is probably not really impressive enough given so many power units, etc.

Looks like a relay so probably to powercycle it. Don't think everything needed is included in the picture. Definitely additional cables for power and networking would need to be added

And yet they have the pi backward so the networking ports are buried. I have no idea what’s going on here.
