Abstract

The embodiment of the invention discloses a realization method and device of a storage QoS (Quality of Service) control strategy, relates to the technical field of storage and can solve the problems that the processing efficiency of a storage system is lowered since the QoS control strategy in the prior art is issued by taking single I / O (Input / Output) of each volume as granular ranking. The method comprises the following steps: determining an amount of I / O processed within unit time; when the I / O which needs to be issued by each volume, determining a weight ratio of the volume to which the I / O which needs to be issued at present; according to the weight ratio and the amount of the I / O processed within the unit time, determining an amount value of the I / O which is continuously arranged and belongs to the same volume in an I / O issuing sequence; and determining the I / O issuing sequence to conveniently issue the I / O which needs to be issued at present according to the order of the I / O issuing sequence, wherein the number of the I / O which is continuously arranged and belongs to the same volume in the I / O issuing sequence is equal to the amount value.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a method and device for realizing a storage QoS control strategy. Background technique [0002] QoS (Quality of Service, Quality of Service), as a network security mechanism of the network, can provide better service capabilities for specified network communications. The main measurement indicators of QoS are IOPS (Input / OutputOperationsPerSecond, the number of read and write operations per second) Lower limit, MBPS (Millionbitspersecond, megabit per second) upper and lower limits, weight share, delay upper limit, etc. In storage systems, competition is usually used to determine the order in which application I / O (Input / Output, input / output) is delivered to the hardware. This will not guarantee the service quality of one or some application I / Os. To ensure the quality of service of some application I / O, scheduling or flow control needs to be performed on the I / O before it is del...
