6 QUESTIONS? Can the hardware and software tango together?

Does the hardware provide mechanisms that the software really needs?

Can the software specify what it needs from the hardware?

At the DC level, what are the real pain-points in energy-efficiency? Need to take a holistic end-to-end approach Are the low DC utilization observations still relevant with

techniques like spot-pricing?
