Yes, 128x128.

Good for a database, maybe.

What else?

Dumb question but why don’t we see more cracked out high memory machines? I mean like 1 petabyte RAM.

Or do these already exist

We don't see more of these machines because most tasks are better served by a higher number of smaller machines. The only benefit of boxes like this is having all of that RAM in one box. Very few use cases need that.
