A method, computer program product, and computing system for defining a token pool size for a storage system token pool associated with a storage system. An input/output (IO) processing load for the storage system may be determined. The token pool size for the storage system token pool associated with the storage system may be dynamically adjusted based upon, at least in part, one or more changes in the IO processing load determined for the storage system.

System and method for dynamically adjusting priority-based allocation of storage system resources

A technique writes data to a storage array. The technique involves operating storage circuitry in a 'FILL HOLE' mode in which the circuitry writes a stream of first data portions within storage portions of used storage stripes of the array. The technique further involves, after operating the circuitry in the 'FILL HOLE' mode and in response to a first event, transitioning the circuitry from the &#x201c;FILL HOLE&#x201d; mode to a &#x201c;STRIPE WRITE&#x201d; mode in which the circuitry writes a stream of second data portions within unused storage stripes of the array. The technique further involves, after operating the circuitry in the &#x201c;STRIPE WRITE&#x201d; mode and in response to a second event, transitioning the circuitry from the &#x201c;STRIPE WRITE&#x201d; mode back to the &#x201c;FILL HOLE&#x201d; mode in which the circuitry writes a stream of third data portions within storage portions of used storage stripes of the array.
