System and method of time-based cache coherency maintenance in user file manager of object-based storage system

The invention, and manage metadata and data information efficiently by that in the object-based storage system of the cache coherence system and method of the user file manager, by using the timer maintaining the consistency of the write back (writeback) cache under the time-based Cash relates to systems and methods for consistency. It even increases the user's access each user's file manager are borne by the cache coherence maintenance costs, improve the overall performance of an object-based storage system, which is nopyige the consistency and efficiency of the information. Object-based storage, write-back (writeback) cache, cache coherence, Den Tree (dentry) information, the inode (inode) information
