ASYMMETRIC DISTRIBUTED FILE SYSTEM, APPARATUS AND METHOD FOR DISTRIBUTION OF COMPUTATION

摘要

PURPOSE: An asymmetric distribution file system, an operation distributing device, and a method thereof are provided to distribute various operations to a main metadata server and a sub metadata server, thereby guaranteeing stable performance despite increases in the number of clients and data. CONSTITUTION: A main metadata server(100) executes operations which need to modify metadata. A sub metadata server(110-1~110-m) executes operations which do not need to modify metadata. A data server(120-1~120-n) stores the original copy and a replica of data which are generated or modified by the operations. The main metadata server determines a sub metadata server which requests the operations.
