CONTROLLING HIERARCHICAL STORAGE

摘要

Provided is a method of distributedly storing an individual content in a hierarchical storage system including a solid state storage having a plurality of solid state disks, a hard disk storage having a plurality of hard disks, and a tape storage. The method may include determining a target content to store and an inquiry frequency and a required minimum transmission rate of the target content upon receipt of a request message from a client device, classifying the target content as at least one of a low demanded content, a normal demanded content, a high demanded content, a low transmission rate content, a normal transmission rate content, and a high transmission rate content based on the inquiry frequency and the required minimum transmission rate of the target content, and distributedly storing the target content through at least one of the solid state storage, the hard disk storage, and the tape storage based on the classification result and a distribution and buffering policy.
