摘要/Abstract

摘要： 目前随着海量数据应用的快速发展,如何减少海量数据存储造成的巨大能耗成为研究热点。分析了在线视频点播的海量存储系统,根据正态分布分析视频访问的时间段,结合磁盘的特点提出一种基于视频点播的节能策略。策略中将磁盘的状态划分为不同的等级,降级时根据历史时间间隔调整时间窗口,同时根据视频的种类制定分布,以最终满足系统的性能和节能需求。根据计算,使用节能策略后系统平均节能达到44%。

Abstract: Now with the rapid development of mass data application,how to reduce the huge energy consumption has become research focus．This paper analyzed the mass storage characteristics of online video on demand.It analyzed video access period according to normal distribution,and combining the characteristics of the disk technology,put forward a kind of energy-saving strategy based on VOD,in which the disk is modeled into different levels.When downgrading,time window is adjusted based on historical time interval,and distribution is formulated depending on the type of video system in order to ultimately meet the demand of the system’s performance and energy conserving at the same time.According to the calculation,average energy saving reaches 44percent after using energy saving strategy.

Key words: VOD,Energy-saving strategy,Mass storage
