METADATA MANAGEMENT DEVICE AND METHOD IN AN ASYMMETRIC DISTRIBUTED FILE SYSTEM, WHICH DISPERSES ALL DIRECTORIES AND FILES TO A METADATA SERVER
PURPOSE: Metadata management device and method of an asymmetric distributed file system is provided to minimize a phenomenon that the load is focused on a specific metadata server by dispersing all directories and files to metadata servers. ;CONSTITUTION: A metadata storage(12b) stores the metadata corresponding to the partition of a part of a virtual metadata address space. The virtual metadata address space stores the metadata for directories and files by partitions. A metadata storage manager(12a) stores the metadata in the metadata storage and manages a master map including the information about a part of the partition.;COPYRIGHT KIPO 2011
