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.
- PunchyHamster 11mo agoSeriosuly, like surely they could've at least used 1 rpi per rack ? Or find cable with matching length?
- jcheng 11mo agoInteresting that they run them upside down.
- teaearlgraycold 11mo agoIt’s because the power button is on the bottom.
- jitl 11mo agoalso hot air rises, and the vent is on the bottom
- matthews3 11mo agoFans can move a lot more air than convection.
- 3eb7988a1663 11mo agoWhy are they still even in the cases? I would assume that shucking them would ever so slightly improve thermals.
- joahua 11mo agoAluminium designed in as heat sink perhaps? But not sure if this is so relevant in an actively cooled DC setting as passive buried under cables at a home workspace!
- itrash 11mo agoWe 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)
- ey3ball 11mo agoAgree, 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
- rcmore0 11mo agoHad a similar problem in T43 HDD.
- itrash 11mo agoActually the power button is pretty useless, they set it up like this for the airflow as the mac mini fans are on the back.
- ey3ball 11mo agoAlso, it's useless during the lifecycle but it simplifies operations a lot during the initial install & any kind of servicing. We're actually thinking about features which will that power button to good use in a near feature, stay tuned !

- throwaway31131 11mo agoThe 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.
- hinkley 11mo agoFans 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.
- trebligdivad 11mo agoIt might be that they're limited by something else in their existing racks; say power or networking ports, so this is an easy hack to get into their existing rack scheme.
- aneutron 11mo agoMy guess is its the size of the blades. e.g. https://servermall.com/fr/sets/serveurs-blade-dell/?srsltid=AfmBOoq4dpBSP7U-MPwVf2LSHkOYf1IJj9NFAX0SjoXMvrqLwivSrLHE https://servermall.com/fr/sets/serveurs-blade-dell/?srsltid=...
- ey3ball 11mo agoI agree the picture doesn't do it justice, it doesn't show the full cabling, we might share a new one. Also keep in mind that these SLEDs are compatible both with the M2 & the M4. M2 require more surface area & cover the whole free space on the SLED
