Abstract
A multi-disk fault-tolerant system, a method for generating a check block, and a method for recovering a data block are provided. The multi-disk fault-tolerant system includes a disk array and a calculation module connected through a system bus, the disk array is formed by p disks, and a fault-tolerant disk amount of the disk array is q; data in the disk array is arranged according to a form of a matrix M of (m+q)×p, where m is a prime number smaller than or equal to p−q; in the matrix M, a 0row is virtual data blocks being virtual and having values being 0, a 1row to an (m−1)row are data blocks, an mrow to an (m+q−1)row are check blocks. Therefore, during a procedure of generating the check block and recovering the data block in the multi-disk fault-tolerant system, calculation complexity is lowered.
