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.
Yeah I'm a bit confused on that. In the picture, each row is definitely taller than the power strip, plus 1U is 44.45mm in height, whereas the current-gen Mac Mini is 50mm high.
I'm pretty sure the drawers are 2U, but given that I don't know how they would get 96 nodes in a standard 42U rack.
