Free whitepaper: Calculating total power requirements for data centers
A month ago, IBM and the University of Illinois broke ground for the
data center that will eventually house the Power7-based "Blue Waters"
massively parallel supercomputer. The data center, it turns out, is as
tricky to design as the processor and server that will be humming along
inside it.
During a talk at the recent SC2008 supercomputing event in Austin,
Texas, someone said it would not be long before power companies would be
giving away supercomputers to any governmental agency or corporation
that signed a long-term power contract. This was a joke. But it brings
into sharp focus the fact that power and cooling are the main
limitations on scalability for supercomputers. That's been the case
since the first Cray-1 vector super came out in 1976
