Abstract
A data storage subsystem including a storage disk array employing dynamic data striping. A data storage subsystem includes a plurality of storage devices configured in an array and a storage controller coupled to the storage devices. The storage controller is configured to store a first stripe of data as a plurality of data stripe units across the plurality of storage devices. The plurality of data stripe units includes a plurality of data blocks and a parity block which is calculated for the plurality of data blocks. The storage controller is further configured to store a second stripe of data as a plurality of data stripe units across the storage devices. The second plurality of data stripe units includes another plurality of data blocks, which is different in number than the first plurality of data blocks, and a second parity block calculated for the second plurality of data blocks. Furthermore, the second plurality of data blocks may be a modified subset of the first plurality of data blocks. The storage controller is also configured to store the second plurality of data blocks and the second parity block to new locations.
