Abstract: The present disclosure relates to the field of information technology, and in particular, to a block storage-based data processing method, apparatus, and system. The block storage-based data processing method provided in embodiments of the present disclosure is applied in a system including at least two storage nodes, each storage node including a CPU, a cache medium, and a non-volatile storage medium, and the cache medium in all the storage nodes forming a cache pool. According to the method, after receiving a data operation request sent by a client, a service processing node sends the data operation request to a corresponding storage node in the system according to a logical address carried in the data operation request, so that the data operation request is processed in the cache medium of the storage node under control of the CPU of the storage node.
