Abstract

METHOD FOR ACCESSING DISTRIBUTED STORAGE SYSTEM, RELATED APPARATUS, AND RELATED SYSTEM A method for accessing a distributed storage system, a related apparatus, and a related system are disclosed. A data access method is applied to the distributed storage system, the 5 distributed storage system includes m storage nodes, the m storage nodes include a first storage node, and each storage node includes at least one memory. The method includes: receiving, by the first storage node, a first data read request from a terminal; and if the first storage node determines, based on the first location information, that a memory in which the first data is located is a first memory, and the first memory belongs to the first storage node, 10 when a state information set currently records that the first memory is in a trusted access state, reading, by the first storage node, the first data from the first memory, and sending a first data read response used for responding to the first data read request to the terminal. A data read amount is reduced, thereby helping reduce memory load and further helping improve system performance. 15 Figure 3A
