Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] to combine figure 1 It can be seen that the main modules of the present invention include business I / O feature classification, global application API, and cloud storage data distribution main modules.

[0023] Classification of business I / O characteristics

[0024] Various services are run on cloud storage, and effective acquisition and analysis of I / O characteristics on cloud storage systems has become an important basis for cloud storage system performance optimization and parameter setting. In the present invention, the I / O characteristics of the cloud storage system are obtained mainly through the I / O monitoring module, and the information is collected and analyzed by monitoring the I / O operation process of the client. The main I / O characteristic analysis on the cloud storage system includes the following:

Abstract

The invention discloses a multi-service application orientated cloud storage data distribution method which comprises the following steps: I / O (Input / Output) characteristics of various services operated on the cloud storage are analyzed, and the service classification is carried out; different application APIs (Application Program Interface) are established according to the I / O characteristics of different services, wherein the application API is the I / O characteristics based on various services; application-based file opening, reading, writing and closing interfaces are provided; a query data layout sheet is made according to service classification results; when a data operation request is transmitted from a client, the I / O characteristic analysis and classification are carried out according to the service of the operation request, and subsequently different application APIs are called according to the I / O characteristics of different services; and the operation request accesses to storage nodes of the service data through corresponding application APIs according to the query data layout sheet. Aiming at the problem that the applications on a cloud storage system are influenced by each other and according to the I / O characteristics of different applications, different data distribution strategies are made, the stable operation of the applications is ensured, and the system performance is maximized.

Description

technical field [0001] The invention relates to a multi-service application-oriented cloud storage data distribution method. Background technique [0002] The bottom layer of the cloud storage system is composed of many devices or even thousands of devices. The bottom devices of different systems are different, and data is stored on these devices in the form of blocks, objects, and files. Data layout refers to storing the data collection generated by the upper layer application of the storage system on the device collection. The data layout strategy mainly solves the problem of how to select the devices in the virtual pool to store data, uses an effective mechanism to establish the mapping relationship between the data set and the device set, and needs to meet certain specific goals. The data layout method directly affects the access performance of I / O, the availability and scalability of the storage system, and so on. Different goals drive different data layout strategies...
