Abstract
A cache coherency maintenance system and method of a user file manager in an object-based storage system are provided. According to the cache coherence maintenance system and method, by maintaining the coherency of a writeback cache based on time using a timer, metadata and data information are efficiently managed. Accordingly, even when accesses by users increase, the cost of maintaining the coherency of the cache is distributed to respective user file managers. In this way the performance of the entire object-based storage system is enhanced and the consistency and efficiency of information increase.
