ABSTRACT:
In a redundant storage subsystem including an array controller and a group composed of a plurality of storage devices, a method is provided. The method includes logically parsing each storage device of the group into a corresponding number of allocation units. A stripe size is selected, and a series of writing operations is performed. Each writing operation includes selecting a subset of the plurality of storage devices based on the stripe size, and writing the stripe of data to the subset of the plurality of storage devices. The selected subset over the series of writing operations varies from operation to operation.
