Abstract:
Systems and methods which implement repair bandwidth control techniques, such as may provide a feedback control structure for regulating repair bandwidth in the storage system. Embodiments control a source object repair rate in a storage system by analyzing source objects represented in a repair queue to determine repair rate metrics for the source objects and determining a repair rate based on the repair rate metrics to provide a determined level of recovery of source data stored as by the source objects and to provide a determined level of repair efficiency in the storage system. For example, embodiments may determine a per storage object repair rate (e.g., a repair rate preference for each of a plurality of source objects) and select a particular repair rate (e.g., a maximum repair rate) for use by a repair policy. Thereafter, the repair policy of embodiments may implement repair of one or more source objects in accordance with the repair rate.
