Storage device management method and device

The invention discloses a storage device management method and device. The method comprises the following steps that: host equipment acquires a notification message from storage equipment, and the notification message indicates that the host equipment has a background management task to be controlled; the background management task is a task executed on the storage device, but the storage device does not directly execute the background management task. However, when the host device determines that the IO service state of the storage device meets the set scheduling strategy, the host device sends the first control command of the background management task to the storage device, and the set scheduling strategy is obtained based on the set QoS requirement. The background task of the storage device and the background IO command generated by the background task are scheduled through the host, and the probability that the background IO command and the foreground IO command of the storage device conflict is reduced,
