Storage system comprises a second storage apparatus, which is coupled to multiple first storage apparatuses and is of a different type from the first storage apparatuses, and a first control device, which exists either inside or outside of the second storage apparatus. Row of stripes comprising multiple data elements obtained by segmenting a prescribed data unit, and a redundancy code for rebuilding the data elements, is distributively stored in multiple first storage apparatuses, which are more numerous than the total number of stripe data elements, which are either the data elements or redundancy code, in the row of stripes. The row of stripes is configured to enable the rebuilding of the stripe data elements even when a failure has occurred in up to a prescribed allowable number, which is two or more, of the first storage apparatuses storing the stripe data elements of the relevant row of stripes. |
