Abstract
The present invention discloses a data storage system in a communication network, which enables distributed storage of data. The system includes front end nodes, storage nodes, super nodes and management nodes. The operation units are located in the front end nodes, the super nodes or the storage nodes and each adapted to operate a first data GUID by a preset fixed offset to derive a second data GUID, to determine, from loop link information obtained from the management node and the second data GUID, a super node with a node identifier closest to the second data GUID, and to forward a service request carrying the second data GUID and a backup flag to the determined super node. The invention further discloses a data information processing method using the system.
