The memory size of the data. For example, the user can set the storage area of the storage node to occupy 20 GB of storage space, and the storage space occupied by the storage area cannot exceed the maximum storage space of the storage node server.

The synchronization module 30 is configured to synchronize the request information to a slave storage node in the cluster file system.

In this embodiment, when the system initiates initialization, the control node sends a message to the server that is set as the primary storage node, and controls the primary storage node to start the program, and the other storage nodes do not start the service program, and can only receive and A request information for storing a read or write request synchronized by the primary storage node, and only the primary storage node synchronizes the read or write request to all slaves in the cluster file system upon receiving a data read or write request The storage node stores the requested information of the read or write request received from the storage node into its buffer area without any other operations.
