Measuring energy consumption of a database cluster

Abstract

Energy consumption of database servers is a growing concern for companies as it is a critical part of a data center's cost. To address the rising cost and the waste of energy, a new paradigm called GreenIT arose. Hardware and software developers are aiming at more energy-efficient systems. To improve the energy footprint of database servers, we developed a cluster of small-scale nodes, that can be dynamically powered dependent on the workload. This demo shows the measurement framework we set up to measure hardware components as well as an entire cluster of nodes. We'll exhibit the measurement devices for components and servers and show the system's behavior under varying workloads. Attendees will be able to adjust workloads and experience their impact on energy consumption.
