Abstract
According to the method for determining a redundant array of independent disks provided in the present invention, for an actual physical disk including n disk groups in which each disk group includes m disks, the n disk groups include m2*(m*n) logical blocks, and a logical block matrix corresponding to m distributed RAIDs can be generated. Therefore, a correspondence between the actual physical disk and the distributed RAIDs can be obtained. In a scenario of data storage or the like, a mapping relationship table of the physical disk and the RAIDs does not need to be stored.
