Adaptive Management of Energy Consumption Using Adaptive Runtime Models

Abstract

A promising avenue to control energy-related costs in enterprise data centers is to investigate power-aware resource management strategies. In this study we investigate techniques to schedule resources adaptively with the sole aim of reducing power consumption. Our approach is based on a characterization of energy usage and resource utilization patterns obtained by monitoring energy consumption in an enterprise data center. We propose an adaptive feature extraction method to classify resource utilization patterns from energy consumption data. Improved classification results are obtained through signal feature extraction prior to the training stages for cascading classifiers for at least 14 different energy usage patterns. Adaptive feature extraction prior to classifier training improved class identification even further. The identified patterns can now be used as a basis for adaptive resource scheduling within a power-smart data center. The classification method that performed best is part of our proposed energy runtime model and controller which manages and controls the energy consumption in the data center according to usage patterns.
