In this embodiment, the data storage request sent by the node may include the size of the data. Step 102: The management server allocates a storage space for the data in a shared storage area, and returns an address of the storage space to the node.

If the data storage request of the step 101 includes the size of the data, the management server may allocate a storage space for the data in the shared storage area according to the size of the data. It can be understood that the management server may not divide the data storage space according to the size of the data, that is, allocate a fixed storage space for each data, and the specific storage space division manner does not constitute a limitation of the present invention.

It can be understood that, after receiving the data storage request sent by the node, the management server may further include:

The management server allocates a storage identifier for the data, and records a correspondence between the storage identifier and an address of the storage space.

The storage identifier herein may be used to identify the uniqueness of the data in the network. If the management server changes the address of the storage space allocated by the data in the shared storage area, the correspondence between the storage identifier and the address of the storage space is updated. When the node reads the data through the storage identifier, the correctness of the read data can be guaranteed.

In this embodiment, the management server is a network entity that performs storage management on the shared storage area.

Step 103: The node stores the data into the shared storage area according to the address. The node and the shared storage area may be connected through a dedicated data transmission channel; the node stores the data in the shared storage area through the dedicated data transmission channel, where the dedicated data transmission channel may be: optical fiber data Transmission channel or small computer system interface ( Small Computer
