Abstract
A control apparatus sends a data access request to a first memory sharing device, wherein the data access request includes an address of target data. The first memory sharing device determines that the target data is stored in a second memory sharing device according to the address of the target data and an address list. The address list includes corresponding relationships between addresses and memory sharing devices, and first addresses corresponding to the first memory sharing device are different from second addresses corresponding to the second memory sharing device, and forward the data access request to the second memory sharing device. The second memory sharing device obtains the target data based on the address of the target data, and sends the target data to the first memory sharing device. Then the first memory sharing device forwards the target data to the control apparatus.
