英文摘要： With the explosive growth of digital information, users put forward new demands on the mass data storage. Energy consumption is increasingly serious caused by the increasing scale of data storage. Energy saving technologies based on performance guarantee therefore become a research hotspot. This project studies the key technologies in the process of energy saving based on the cloud storage systems. Specific include: In order to meet the real-time online service of cloud storage systems, it studies the multi-target data hierarchical storage strategy; to meet the reliability and performance of cloud storage systems, it studies an energy saving technology based on data migration that ensures the reliability and performance; to meet the massive data management and reduce the capacity requirements for massive data storage in cloud storage systems, it studies an energy saving technology based on data de-duplication. Finally, it builds an energy-efficient cloud storage platform based on Hadoop to test the proposed energy saving strategies. The main goal of the project is to research on key technologies of energy saving for the cloud storage systems, which starts from the aspects of data storage and management, aims to meet the new characteristics of cloud storage systems, makes the cloud storage systems meet the needs of users while achieving energy saving.
