IMHO putting 30 Spooners in one rack is a non-starter.
Because of the heat density you would have to spread them amongst racks.
Most ordinary racks can not dissipate more than about 10KW with the doors closed without some serious (i.e. expensive) cooling solurtion (water cooling, sealed hot/cold aisle, high volume air flow, etc.).
Also, most data centres are not designed to handle that kind of spot heat output (I worked in data centres for 36 years).
Sorry, big generalisation here as I do not know your precise circumstances, but when I watched their video when they said you could put 30 in one rack I split my sides laughing. Grin

You're welcome to visit our state of the art DC in Israel. No water cooling, very efficient air cooling.

Thanks for the offer but I don't think I can take you up on it this year (I would like to because that's what I spent most of my life doing, auditing DC's, it's almost like a hobby of mine now).
I'm sure you have a nice new "state of the art" DC but my point was that most are not.
I worked in a DC with 1.3 PUE, it was in Scotland. It was designed to 1.5KW/m2.
Credits to you running that PUE in Israel, where I imagine the average temperature is somewhat higher.
But you have mountains there so perhaps you could locate it at a cooler altitude?
Anyway, 30 of your SP10 units in a 45U rack would output ~36KW.
Even removing the doors and using a sealed hot/cold aisle with high-volume chilled air input you must be seeing exhaust temperatures in the 80C range.
And what's the benefit?
Most DC's are not that short of floor space.
You would run out of power input capacity at that power density before you ran out of floor space.
Nobody designs to 12KW/m2.
(IMHO).
