Eight just about, but its scaling I cant judge. 16 or 32 with modern hardware
not really - you are into clustering or NUMA territory.

Cellular Irix.

32-64GB is out of the intel arena altogether. You are firmly in mainframe
land unless clustering stuff would work. Go set Sun, IBM and SGI bidding
against each other and get some third party disk quotes 8)
