Embodiment Construction

[0023] The following is based on figure 1 with figure 2 The specific embodiment of the present invention is further described:

[0024] see figure 1 , a QoS setting method for the Ceph cloud storage system based on the token bucket algorithm, which provides the limit (restriction) requirement in the QoS guarantee, and can handle certain emergencies, allowing the customer's IOPS to temporarily exceed the limit value. Described Ceph cloud storage system comprises a plurality of clients and the service end that is connected with a plurality of clients communication, and described service end is provided with total token bucket module, comprises a plurality of sub-token bucket modules in the total token bucket module , there is a one-to-one correspondence relationship between each client and each sub-token bucket module, wherein the total token bucket module is a total token bucket, including many small token buckets (sub-token buckets) card bucket module), corresponding to ea...

Abstract

The invention discloses a QoS setting method of a Ceph cloud storage system based on a token bucket algorithm. The Ceph cloud storage system includes a plurality of clients and a server connected to the plurality of clients in communication. The server is provided with The total token bucket module, the total token bucket module includes a plurality of sub-token bucket modules, each client has a one-to-one correspondence with each of the sub-token bucket modules, the present invention provides The limit limit in QoS, when many clients perform IO operations, can limit their maximum IOPS, which can avoid the phenomenon that some clients occupy a large number of IOPS while other clients are hungry; at the same time, it provides the ability to handle bursts, and the depth of the bucket That is, the maximum number of tokens held by the sub-token bucket module can handle the sudden large IO, avoiding problems such as jitter.

Description

technical field [0001] The invention belongs to the field of distributed storage, and in particular relates to a QoS setting method of a Ceph cloud storage system based on a token bucket algorithm. Background technique [0002] Cloud storage is an emerging concept that is extended and developed from the concept of cloud computing. It refers to a large number of different types of storage devices in the network such as cluster applications, network technology or distributed file systems that work together through application software to jointly provide services to the outside world. A system of data storage and business access functions ensures data security and saves storage space. [0003] QoS (Quality of Service) is a control mechanism that provides different priorities for different users or different data streams, or ensures that the performance of data streams reaches a certain level according to program requirements. In the field of packet switching network, QoS refer...
