The invention discloses a data storage method and apparatus. The method comprises the following steps of acquiring to-be-stored data, determining a rack corresponding to the data in storage space via Hash calculation, acquiring a data copy corresponding to the data and determining a storage area of a data node of the data copy on the rack via Hash calculation, and storing the data copy in the storage area, wherein the storage space is annular storage space; the data node is corresponding to a plurality of virtual data nodes; and the storage space charged by the plurality of virtual data nodes are evenly divided into a plurality of storage areas. By the use of the data storage method and apparatus, data can be evenly distributed and quickly stored; and system processing performance can be improved.
