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
