The present invention relates to the technical field of information technologies, and particularly to a data processing method, device and system based on block storage. The data processing method based on block storage provided by embodiments of the present invention is applied to a system comprising at least two storage nodes; each storage node comprises a CPU, a buffer medium and a non-volatile storage medium, and the buffer medium in each storage node forms a buffer pool. In this method, after receiving a data operation request sent by a client, a service processing node sends the data operation request to the corresponding storage node in the system according to a logic address carried in the data operation request, so as to process, under the control of the CPU of the storage node, the data operation request in the buffer medium of the storage node. Through the method provided by the embodiment of the present invention, the number of the storage nodes is added to increase the capacity of the buffer medium in the system, thereby enhancing the expandability of the buffer medium in the data processing system. |
