8 Opterons and up to 128GB ram. It has 4 memory sockets per cpu. I
guess that means they think you can get 4GB dimms. Of course they have
only tested 2GB dimms so far it would appear. I guess 4GB comes later
if ever.
As for who can afford that? I have no idea. Of course NUMA machines
often have much more, but at the same time they probably don't manage
their memory in quite the same way since the physical memory is less
than 64GB per node I suspect and hence can be addressed fairly normally
and memory on other nodes has to go through something else anyhow.
Having never worked on one I am not quite sure how they manage all that.
