Abstract
A method, apparatus, and program product applicable within a multi-drive data storage system for adaptively allocating data reconstruction resources. In accordance with the method of the present invention, responsive to a detected drive failure, a resource allocation manager periodically determines the number of pending host system processing requests. The determined number of pending host system processing requests is then compared to a predetermined threshold value. Finally, a number of processing resources are allocated to data reconstruction in accordance with the results of the comparison of the number of pending host system processing requests to the predetermined threshold.
