Abstract

The present invention relates to a data management method in network storage system. Said data management method is characterized by that a kernel supervisor is set in the interior of storage server in the network storage system, the described kerner supervisor can be used for making the storage space corresondent to the described storage server be formed into common storage space, and making every storage server be separated from its managed correspondent metadata and be formed into storage supervisor, so that the described kernel supervisor in the described every storage supervisor can be used for managing the storage position of metadata in the described common storage space and correspondent relationship of metadata and the described storage supervisor.

Description

technical field [0001] The invention relates to the technical field of network storage, in particular to a data management method in a network storage system and a network storage system constructed thereof. Background technique [0002] The network storage system is based on the storage network, with the storage server as the core, providing data storage services for application servers. The system emphasizes the scalability, high reliability and dynamic processing capabilities of data services. Currently, the commonly used technology is storage Area Network (SAN). [0003] A storage area network is an independent data network composed of several storage servers, storage devices and storage network devices, connected through a dedicated interconnection, and is a high-speed, dedicated, centralized management and secure information system architecture. [0004] In a storage area network, the expansion of a storage server that provides data services to the outside will lead t...
