Double-controller communication system and method based on hard disk controller

Abstract

The invention discloses a double-controller communication system and a method based on hard disk controller, which are applied in the computer system with double controllers and utilizes the respective hard disk controllers of two controllers to realize the internal communication between the two controllers. The technology content lies in that the main controller core of a first controller can send the request in the form of Ethernet packet before the emulation of Ethernet communication in the two controllers, and the hard disk controller which is as the originating terminal can receive requests and send requests to the hard disk controller which is the corresponding terminal of the second controller through the internal transform of requests form. Through the reducing treatment of opposite program, the second controller can reacquire the requests in the form of Ethernet from controller core so as to implement correspondent program, thus finishing the internal communication between the double controllers.

Description

technical field [0001] The invention relates to a data processing system and its method, in particular to a system and its method for realizing internal communication between two controllers through a hard disk controller by using a simulated Ethernet communication mode. Background technique [0002] At present, in some application environments that require high data integrity and service continuity in data services, taking the application environment of regional storage network services as an example, computer systems with dual controllers are often used. The main purpose of dual controllers is to When the first controller is providing services, the second controller can be used to mirror it, so when the first controller is abnormal or even shut down and cannot continue to provide services, the second controller can immediately take over and continue Provide services that meet requirements for data integrity and service continuity. [0003] In order to realize the above-me...

Problems solved by technology

[0005] 1. Additional hardware needs to be connected to the computer system, resulting in reduced available space

[0006] 2. Additional hardware needs to be connected to the computer system, which increases the cost of purchasing hardware

[0007] 3. The application of dedicated hardware for communication can only transmit simple synchronous signals, and cannot provide large data transmission

[0008] 4. The application of dedicated hardware for communication is quite poor in adapting to different hardware compatibility and portability
