description The invention relates to a storage service quality guarantee system based on IO weighted fair queuing, which comprises a performance proportion distinguishing controller, a performance measurement monitor and an IO resource distributor, the performance measurement monitor continuously and periodically monitors the performance index of each load; a measurement result is transmitted to the proportional controller; the reference datum value of the proportional controller is determined according to a pre-specified proportional performance specification; the proportional performance specification stipulates the proportional relation between the QOS quality grade and the load performance; according to a specified control rule, a resource share which should be accepted by each load is calculated,a corresponding proportion parameter is submitted to an IO resource distributor which serves as an actuator, and according to the specified control rule, the resource share is calculated according toa load performance propor
