Embodiment Construction
[0036] Dual-controller communication is the basic module of a dual-controller storage system. Target virtualization instructions (such as PR instructions), cache mirroring, and HA all rely on the communication link provided by multi-controller communication. At the same time, the Request-Reply (Request-Response) communication model As a traditional communication model, it has been widely used in the interconnection communication between dual controllers. Therefore, how to abstract data for different applications, simplify the communication model, provide a consistent API for applications, and provide a consistent request and response interface is particularly important. In view of this, the core of the present invention is to provide a communication method and a communication model with consistent application interfaces to simplify applications.

The present invention discloses a communication method and communication model for implementing communication between two controllers. The method comprises: when a first controller sends a request by means of a first interface, setting a command prompt of the first controller as a request flag bit; the first controller sending request data to a second controller; the second controller receives the request data, setting a command prompt of the second controller as a response flag bit; the second controller sending the request data to an application by means of a second interface; after the application receives the request data, sending response data by means of the second interface; and the first controller receiving the response data by means of the first interface to complete communication. According to the communication method and communication model for implementing communication between two controllers provided by the present invention, application interfaces are simplified, and the maintenance cost is reduced, thereby improving product competitiveness.
Description
technical field [0001] The invention relates to the field of storage technology, in particular to a communication method and a communication model for realizing dual-controller communication. Background technique [0002] At present, the dual-controller disk array has become the basic unit for building a large-scale storage system. The communication between the dual-controllers is the core component of the disk array. The complexity of its communication model directly affects the complexity of the dual-controller disk array. [0003] Dual-controller communication is the basic module of a dual-controller storage system. Target virtualization instructions (such as PR instructions), cache mirroring, and HA all rely on the communication link provided by multi-controller communication. At the same time, the Request-Reply (Request-Response) communication model As a traditional communication model, it has been widely used in the interconnection communication between dual controller...
