| Abstract | Digital information management is the key enabler for the unparalleled rise in productivity and efficiency gains experienced by the world economies. Enterprise computing systems are important elements of the world’s digital infrastructure by providing ever-present and ever-increasing information processing, storage, and networking capabilities. As such, they are also significant drivers of economic growth and societal changes. However, continued expansion of enterprise computing systems is now hindered by their unsustainable and rising energy needs. Moreover governments, people, and corporations are becoming increasingly concerned about the environmental impact of enterprise computing systems and their supporting cyber-physical structures. It is with this backdrop that I will present a number of best practices and methods for improving the energy efficiency of enterprise computing systems, ranging from core-level to platform-level power management, from design of energy proportional hardware to system-wide provisioning of heterogeneous resources, and from task scheduling to virtualization. |
