I had an HP from 2010 that supported 1.5TB of ram with 40 cores, but it was 4U. I'm not sure what the height has to do with memory other than a 1U doesn't have the luxury of the backplane(s) being vertical or otherwise above the motherboard, so maybe it's limited space?

Theres different classes of servers, the 4U ones are pretty much as powerful as it gets, many sockets (usually 4) and a huge fabric.

1Us are extremely commodity, basically as “low end” as it gets, so I like to use them as if they are a baseline.

A 1U that can take 1.5TiB of ram might be part of the same series of machines that might have a 4U machine that could do 10TiB. But those are hugely expensive. Both to buy and to run
