Abstract
A data storage apparatus has a plurality of n disks and data comprising a plurality of data groupings stored respectively across the plurality of n disks. Each one of the n data groupings comprises a data portion and a data redundancy portion. Advantageously, the n data portions are recoverable from any and all combinations of n−m data grouping(s) on n−m disk(s) when the other m data grouping(s) are unavailable, where 1≦m<n. The disk storage apparatus may be configured for a parameter m which is selectable.
