Abstract

An embodiment of the invention provides a data transmission method, device and system of a data storage system. The data transmission method includes: a central processing unit interface configured on data transmission equipment receives a data transmission instruction transmitted by a central processing unit so as to obtain target storage media corresponding to address precedence codes, the data transmission instruction is transmitted to the target storage media through target storage medium interfaces connected with the target storage media, and the data transmission instruction is executed in the target storage media, wherein each address precedence code corresponds to one of at least two storage media of different types. The method has the advantages that the central processing unit can be connected with different storage media by being connected with one central processing unit interface disposed on the data transmission equipment, the pin resources of the central processing unit are saved, and the utilization rate of the pin resources of the central processing unit is increased.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data storage, and in particular, to a data transmission method, device, and system for a data storage system. Background technique [0002] At present, cloud computing applications represented by large-scale distributed Internet applications and big data applications have put forward high requirements on the performance of data center servers. For example, large-scale distributed Internet applications often need to provide low-latency, high-throughput performance, while Big data applications require large-capacity memory and high-speed IO storage devices. [0003] In existing storage systems, different storage media are connected to the CPU using different buses and interfaces. For example, the memory controller integrated in the CPU directly communicates with the DRAM (Dynamic Random Access Memory) through the memory bus. , hereinafter referred to as DRAM), the central processing u...
