Energy-Efficient Storage in Virtual Machine Environments

Free registration required

Executive Summary

Current trends in increasing storage capacity and virtualization of resources combined with the need for energy efficiency put a challenging task in front of system designers. Previous studies have suggested many approaches to reduce hard disk energy dissipation in native OS environments; however, those mechanisms do not perform well in virtual machine environments because a Virtual Machine (VM) and the Virtual Machine Monitor (VMM) that runs it have different semantic contexts.
