Abstract
A data management method for network storage system that said network storage system includes a storage network, a cluster of storage servers that provide data storage services for application servers connecting to the storage network and storage space corresponding to each storage server, setting a core manager in storage server, said core manager centralizing the metadata of all storage servers in a common storage space; separating the metadata from said storage servers to make a storage server become a storage manager and the storage spaces corresponding to each storage server form the common storage space, allocating the storage space of metadata in said common storage space, and managing the corresponding relationship between metadata and said storage manager.
