Distributed data storage system and method

The invention discloses a distributed data storage system and a distributed data storage method. The distributed data storage system comprises an interface machine process module, at least one service process module and at least one storage module, wherein the interface machine process module is used for receiving a storage request which comprises data to be stored from a storage requesting party, and distributing the storage request; the at least one service process module is used for allocating a storage identifier, and providing data storage service; one of the at least one service process module receives the storage request from the interface machine process module, and allocates the storage identifier to the data in the storage request; and the at least one storage module is used for storing the data according to the storage identifier allocated by one of the at least one service process module. By the distributed data storage method and the distributed data storage system, stable and high-concurrency ma
