Designing Energy-Efficient Servers and Data Centers
The performance, cost, and reliability of modern servers and data centers are dictated in large part by the effective management of limited power and thermal budgets. Building energy-efficient systems often entails solving problems at multiple system levels, e.g., circuits, architecture, system software, and applications. This talk will present a variety research projects underway at IBM Research - Austin. These projects include: (i) energy management mechanisms that actively manage the power consumed by individual components within a server (e.g., processors, memory, fans, and power supplies), (ii) low-power high-performance storage servers that exploit flash and energy-aware caching/replication policies to reduce storage power, (iii) next generation scalable and energy-efficient data center networks, and (iv) integrated IT and facilities energy management. The talk also will introduce a set of design principles for building more energy-efficient systems that IBM researchers have developed based on the insights from a decade-long focus on energy efficiency and identify remaining technical challenges that must be addressed to substantially improve energy-efficiency of future servers and data centers.

BIO: John Carter leads the Power Aware Systems research group at the IBM Research - Austin. Dr. Carter and his team are developing an array of technologies designed to dramatically reduce server and data center energy consumption as part of IBM's Smart Planet initiative. Prior to joining IBM Research, Dr. Carter was the Associate Director of the University of Utah's School of Computing, where he led research projects in the areas of multiprocessor computer architecture, distributed systems, and memory system design (e.g., Impulse and Khazana).
