Abstract
Sequentially ordered groups of same-size cells are distributed in a drive array representative matrix as group number=((row number−1)+(column number−1)) modulo (N), where N is the total number of drives. A plurality of the groups are reserved as spare groups. Responsive to a drive failure, one of the spare groups is selected, an ordered target list of spare cells is created, an ordered source list of cells containing protection group members on the failed drive is created, and the spare cells are assigned to the cells containing protection group members on the failed drive, where the protection group members are rebuilt. The target list starts at the spare cell having the minimum drive index that is greater than the failed drive index. The source list is ordered by either sequential cell indices or alphabetically by group-representing letters.
