Rising energy costs in large data centers drive the agenda for energy efficient computing. Towards this goal, it is critical to understand the interplay between energy consumption and performance in database servers. In the first part of this talk, I will focus on quantifying the role of database software in the overall energy efficiency of a server. Then, I will present the results of a recent study (SIGMOD'10) on the power usage profiles of database operators and I will explore the effect of different configuration parameters in the energy efficiency of a database system. Finally, I will discuss our work on query processing on solid state drives (SIGMOD'09), which have emerged as a primary building block for energy efficient storage.

Short Bio:
Stavros is an HP Labs researcher in the Intelligent Information Management Lab which is focused on enabling near real-time business intelligence with robust, scalable data management and data-intensive analytics. He received his Ph.D. in Computer Science from Carnegie Mellon, in 2005, and, through 2007, he worked as a Post-Doctoral researcher at the DB group of MIT. Stavros's research interests are in energy-efficient data management systems, query processing on new processor and storage technologies, main-memory transaction processing, and column-oriented databases.
