Abstract
A distributed data storage method, apparatus, and system. The method includes: splitting a data file to generate K data slices, splitting each data slice of the K data slices to generate M data blocks for each data slice, and performing check coding on the M data blocks by using a redundancy algorithm to generate N check blocks; determining, by using a random algorithm, a first physical storage node corresponding to one block of the M data blocks and the N check blocks, and determining at least M+1 different physical storage nodes based on the determined first physical storage node and according to a first rule-based sorting manner; and storing at least M+1 blocks of the M data blocks and the N check blocks onto the at least M+1 different storage nodes, where K, M, and N are integers.
