There are many services on Internet that people can enjoy them everywhere. These services all need a large-scale storage system to store thousands of data. Although the large-scale storage system provides large storage capability, it also consumes much energy. The traditional energy-efficient storage system usually spins down the hard-disk rotation rate to reduce the energy consumption. However, only spinning down the hard-disk rotation rate can only save little energy. In this paper, we propose an energy-efficient storage system. The system reduces the consumption of energy by switching the server state into the sleep mode. We also propose two scheduling algorithms to handle the offline and online scheduling modes. The experimental result shows the proposed energy-efficient storage system can save about 50%~75% of the energy.
