Abstract
There are disclosed computer-implemented methods, apparatus, and computer program products for managing data storage. In one embodiment, the computer-implemented method comprises the step of receiving new data to be written to storage. The method also comprises the step determining that the new data does not form a full stripe of data. The method also comprises reading missing non-parity data in the stripe of data. The method further comprises determining new parity based on the new data and the missing non-parity data. The method still further comprises writing the new data and the new parity to storage in a manner that does not require the missing non-parity data to be written to storage.
