30,000 servers sounds like an awful lot for "office, IT and web operations". Estimating about 90,000 employees (and it's probably lower[1]) that's 3:1 users per server.
Most of these are SMP machines (and probably multicore chips) so you probably have >1 core per employee... Most of these are probably running engineering tools: simulations, verification, silicon back-end tools.
Current chips require tons of compute power to develop, so this is not surprising [I do wonder how many of these are based on Itanium processors?]
