Not just one - the Sun T2 Niagara is a quite different architecture from 
AMD/Intel. We also test on Itanium and PA-RISC, though less often. And of 
course, anyone with a system that they'd like to see tested is welcome to 
provide us access to conduct such tests. The 8-socket AMD server I mentioned 
above is based at a company in Singapore. As long as we can get network access 
and they can provide load generator machines on the same LAN as the target 
server, it doesn't really matter where the machine resides.
