| Abstract: | Data centers consume significant amounts of energy and the consumption is growing each year. Alongside efforts in the hardware domain, there are some mechanisms in the software domain to reduce energy consumption. One of these mechanisms is dynamic voltage and frequency scaling (DVFS) on CPUs. We show that a DBMS can exploit its knowledge of the workload and performance constraints to obtain power savings that are more than twice as large as the power savings achieved when DVFS is managed by the operating system. We will also discuss how we might extend the work to a more generalized power manager which adapts to different CPUs and workloads. |
