Abstract
An apparatus, system, and method are disclosed for servicing a data storage device. A service registration module registers a service process for servicing the stripe groups of a data storage device. A WIP map initialization module creates a WIP map for each stripe group of the service process. The stripe group selection module selects a stripe group and the service module performs the service process on the selected stripe group. The WIP map update module sets the WIP map entry of the selected stripe group. The stripe group selection module uses the WIP map to avoid the repeat selection of a stripe group to receive the service process. An I/O module may determine from the WIP map if a data block of a stripe group may be accessed during the service process and may direct the service process to the data block's stripe group out of turn to increase performance.
