Economics and sustainability drive the need to manage available energy as a key resource in devising todayâ??s information technology services accessed by billions of users and availed from thousands of data centers. ? The overwhelming â??burdened??? cost of delivery of power to a dense aggregation of industry standard compute, networking and storage hardware in a data center necessitates treating the data center as the computer with an end-to-end management system that provisions the resources based on the need. ? Billions of ubiquitous client devices, with immense text and video functionalities, further tax the power needs of the compute utility. ? Besides power required for electronics in handheld devices, power will soon be required to drive â??active??? cooling solutions in these devices. ? Active cooling solutions will be required as a result of technology trends resulting in high power density due to semiconductor technology miniaturization and integration, integrated photonics and emergence of 3d chip packaging. ? Enabling sustainable ubiquitous connectivity will require judicious provisioning of available energy.

We present a framework for dynamic need-based provisioning of resources using pervasive sensing and control to minimize consumption of available energy. ? The thermal challenges arising from high power density microprocessors and servers in data centers are examined and a â??smart??? data center is motivated based on total cost of ownership and sustainability.? A metric based on the 2nd law of thermodynamics that quantifies performance based on available energy (exergy) is proposed.
