Abstract

The present invention provides a CRUSH-based data storage optimization method, comprising: classifying and storing multiple target data according to data characteristics; adjusting the CRUSH strategy and optimizing the write operation mapping relationship according to the type of the target data; The CRUSH strategy and the optimized write operation mapping relationship store multiple target data to the corresponding disk; thus, a more balanced distribution of data can be achieved, thereby reducing frequent thread switching and memory copying in the process of storing objects on the client side Operation, so as to achieve the purpose of optimizing I / O operation and greatly improving the disk writing speed.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a CRUSH-based data storage optimization method and device. Background technique [0002] Nowadays, the mobile Internet is in its heyday, driving the rapid development of cloud computing, Internet of Things (IoT), artificial intelligence (AI) and other emerging industries, followed by the generation of massive unstructured data, and in Explosive growth. For example, currently people frequently visit shopping websites, video websites, and instant messaging tools, etc., and the back-end storage stores a large number of video, image resources, and user access records, etc. The traditional technical solution is usually that multiple servers are connected to FC fiber storage (shared storage type, not distributed) through the SAN switching network at the same time, and then provide external services. There are many disadvantages in adopting traditional technical solutions, su...
