摘　　要：随着数字化信息爆炸性的增长,存储技术成为IT业发展的新动力。存储系统规模的不断扩大,使能效问题越来越突出,主要表现为增加了系统运行维护和冷却的成本、降低了系统的可靠性和扩展性、加剧了存储系统周围环境的污染,因此研究存储能效问题具有较大的经济价值和实用意义。阐述了存储系统中磁盘能效的研究进展和现状,并从语义信息出发,设计与实现了基于语义信息的驱动程序。实验表明该驱动程序有效地降低了磁盘能耗,提高了存储系统I/O性能,优化了存储能效。With the digital information explosive growth, storage technology has become a new impetus to the development of IT industry, constantly expanding the size of the storage system, energy efficiency problem is becoming more and more serious, main show is increase of system operation and maintenance cost, reduces the system operation reliability and expansibility, exacerbated by the storage system to environmental pollution, so the study of stored energy effi- ciency has great economic value and practical significance. The article elaborated the storage system disk energy current situation and research progress, and from the semantic information of design and realization, based on the semantic in- formation of the driver. Experimental results show that the driver can effectively reduced the energy consumption of the disk storage system, improved the I/O performance,optimized the energy efficiency of storage.
