A method, device and electronic equipment for realizing inter-node communication

Abstract

Embodiments of the present application provide a method, device and electronic equipment for realizing communication between nodes. The method is applied to a user node in a SAS network system connected to a small computer system interface in series; the method includes: obtaining target data to be transmitted sent by a target program; constructing an Ethernet message carrying the target data; sending the Ethernet message The text is encapsulated into a SAS protocol message; the SAS protocol message is sent to the SAS-HBA in the user node, so that the SAS-HBA sends the SAS protocol message to the destination user node as the data receiver through the forwarding node; the destination user When the node receives the SAS protocol message, it decapsulates the SAS protocol message into an Ethernet message, and decapsulates the Ethernet message into target data; wherein, SAS‑HBA is a host bus adapter using the SAS protocol. Through this solution, the communication interface of the SAS network system compatible with the Ethernet can be realized, thereby reducing the coupling between the application layer and the data transmission layer of the user node.

Description

technical field [0001] The present application relates to the technical field of data communication, in particular to a method, device and electronic equipment for realizing communication between nodes. Background technique [0002] SAS (Serial Attached SCSI, Serial Attached SCSI) is a new generation of SCSI (Small Computer System Interface, small computer system interface) technology. Among them, SAS adopts serial technology to obtain higher transmission speed, and improves internal space by shortening connecting lines. Among them, SCSI is an independent processor standard used for system-level interfaces between computers and smart devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). [0003] For the SAS network system, the communication between user nodes can use SAS-HBA (Host Bus Adapter, host bus adapter) for data transmission. In the prior art, in order to realize the communication between user nodes, the communication interface adopted by t...

Problems solved by technology

[0004] Although the user nodes can communicate with each other in the prior art, due to the high coupling between the application layer and the data transmission layer of the user nodes, the program relying on the communication interface of Ethernet cannot be applied to the user nodes of the SAS network system.

The program that relies on the communication interface of Ethernet is a relatively common program in the market, which undoubtedly seriously affects the user experience
