Abstract

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

Description

technical field [0001] This application relates to the computer field, in particular to a storage system quality of service QoS control method and device Background technique [0002] Distributed storage is a storage cluster composed of multiple cheap servers. It connects the storage devices directly connected to each server in the cluster through the network to form a resource pool, providing users with storage resources such as storage blocks, files or objects. . The storage system disperses and stores logical files, storage blocks, or object data of users into the physical disks of each server. That is to say, the same physical disk will be used by multiple users at the same time, resulting in the Business) competition for the same storage resource. [0003] Different businesses have different degrees of importance. The problem of competition for storage resources will cause unimportant businesses to seize storage resources, causing important businesses to fail to work...
