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

I'd think the market share for applications which need huge amount of space, but little CPU processing power and memory transfer rate is rather small.

Lenovo's slides indicate that they foresee this server be used for in-memory data bases.

Weren't there also distributed fs where the meta-data server couldn't be scaled out?
