摘要
A method, computer program product, and computer system for receiving, by a computing device, an I/O request for data. A number of storage devices of a plurality of storage devices in a Mapped RAID group that will be used to process the I/O request may be determined. It may be determined that an amount of I/O credits available for the number of storage devices is insufficient. The amount of I/O credits available for the number of storage devices to process the I/O request may be tuned dynamically based upon, at least in part, determining that the amount of I/O credits available for the number of storage devices is insufficient.
