Abstract
A RAID data storage system includes a heterogenous disk array coupled to a controller. The disk array provides a storage space that includes a first set of stipes each having at least “N” blocks and a second set of stripes each having less than “N” blocks. The controller can operate to map the storage space into redundant units by creating at least one redundant unit for storing data according to a mirror redundancy scheme. The redundant unit includes a block from the first set of stripes and a block from the second set of stripes.
