Storage system QoS (quality of service) control method and device

摘要: The invention discloses a storage system QoS (quality of service) control method and device. includes the steps: receiving IO (input output) requests users for system; calculating reserved time tags corresponding to received users, storing into an request set; screening with not larger than current in set sequence from high low priority according pre-deployed user information, outputting screened process requests. According technical scheme, is controlled by algorithm system, mechanism introduced, distributed some key businesses delay requirements, normal operation ensured.
