Energy Efficient Cloud Storage Service: Key Issues and Challenges

Nowadays energy-awareness represents a big challenge for cloud computing infrastructures as the adoption of cloud computing become a certain fact and together with the increasing costs for energy, calls for energy-aware methods and techniques. The storage system represents an important factor for energy consumption in a data center. Thus this paper, in the context of cloud storage, reviews the methods and technologies used for energy-aware operation of storage systems in data centers. After surveying relevant literature in this area, this paper presents some of the key research challenges that arise when such energy-saving techniques are extended for use in cloud storage environments.
