Abstract
A storage system monitors system performance metrics and client performance metrics related to input/output (I/O) operations. The storage system, generates a performance adjustment value for each client using a proportional-integral-derivative (PID) controller to match the corresponding respective target performance value within a time period based on feedback of the respective monitored client performance metric and the system performance metric. The storage system, throttles I/O operations for each client during the time period such that the respective client performance moves toward the corresponding respective target performance value.
