Analysis of Energy Consumption of Deduplication in Storage Systems

Energy efficiency of storage system is an important research topic as it largely affects the energy consumption of data centers. Although the technology of deduplication can save resources in storage systems, it cannot always achieve good energy efficiency. In this paper, we propose an energy consumption model for storage systems. In addition, an energy-aware backup strategy has been designed for backup tasks to achieve the balance of the process in terms of energy consumption and deduplication efficiency. To validate the model and the strategy, we introduce an energy-aware disk simulation framework and implement it by extending Disk Sim that is widely used for storage research.
