Heh. I think SGI has several terabytes of RAM in a single machine!

... but doesn't Google have several hundred thousand PCs in their
cluster? I guess nobody who knows the real number can comment, but
I think it is in that range. If each one had a GB of RAM, then that
would make several *hundreds* of TB in their cluster...

I think it's over petabyte by now. I've heard from guys in Google that this estimate is pretty close to the reality - and Google built few new datacentres since then. And since they fight for reduced latency they should have systems with a lot of RAM rather than with a lot of disk. So my guess is that they have at least petabyte of RAM and less then exabyte of disk. But nobody knows for sure, obviously...
