The present invention relates to a data access system, comprising: a memory sharing resource pool formed by more than two memory sharing devices, and more than two control devices corresponding to all the memory sharing devices. Any memory sharing device in the more than two memory sharing devices has a uniformly addressed memory unit used for data storage, any memory sharing device obtains, under the control of a control device in the more than two control devices and corresponding to the memory sharing device, data in a memory unit in any memory sharing device in the memory sharing resource pool, and any control device in the more than two control devices is connected to the more than two memory sharing devices by using a communications interface, and obtains, by using uniformly addressed address information and a memory sharing device in the memory sharing resource pool and corresponding to any control device, data in a memory unit in any one or more memory sharing devices in the memory sharing resource pool. |
