Abstract

A distributed data storage method, control device and system, the method comprising: dividing data to be stored into m2 data blocks A (101); according to B generating a first checking block set C (102); wherein D; according to E generating a second checking block set F corresponding to the data to be stored; according to G generating a third checking block set H corresponding to the data to be stored; and respectively sending the m2 data blocks and 2m + 1 checking blocks to different storage devices and storing the same therein (105). Since each checking block is linearly associated with m data blocks, and the data blocks and checking blocks are respectively stored in different storage devices, multiple failed blocks can be restored with a reduced recovery cost.
