DISTRIBUTED STORAGE SYSTEM BASED ON METADATA CLUSTER AND METHOD THEREOF

摘要

PURPOSE: A distributed storage system based on a metadata cluster and a method thereof are provided to supply a storage service regardless of the amount of storage and the number of clients by synchronizing meta data on a cache memory in real time. CONSTITUTION: A storage relay server(10) relays a storage request for a web service client to a meta data cluster(20), and transfers the meat data of the meta data cluster to a file storage server(30). The meta data cluster generates the meta data, and stores the meta data at a cache memory. In addition meta data cluster synchronizes the cache memory through the meta data of the other meta data cluster.
