Enterprises rely on decision support systems to influence critical business choices. At the same time, IT-related power costs are growing and are a key concern for enterprise executives. Yet, there is little work to date characterizing the power use of decision support systems. Towards this end, the paper presents the first holistic measurements and analysis of an audit-class system running the TPC-H decision support benchmark at the 300GB scale. The paper first provides a break-down of the system's power use into its core hardware components. The paper then explores its power-performance tradeoffs.
