Backboard, hard disk pool, server and communication method

Abstract

The embodiment of the invention provides a backboard, a hard disk pool, a server and a communication method. The backboard comprises a plurality of standard backboards which are connected with the same communication bus interface of a controller and are cascaded in series, and the standard backboards are used for generating address information corresponding to the standard backboards when address generation signals are input into first ports. The address information is used for indicating the controller to communicate with the standard backboard through the communication bus interface, and is also used for updating an address generation signal and sending the updated address generation signal to the next-level standard backboard through the second port so as to indicate the next-level standard backboard to generate corresponding address information; and communicating with the controller through the corresponding address information. According to the backboard provided by the embodiment of the invention, a plurality of standard backboards are connected to the same communication bus interface, and corresponding address information is configured for different standard backboards for distinguishing, so valuable interface resources are saved on the premise of realizing flexible configuration.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automation control, and in particular to a backplane, a hard disk pool, a server, and a communication method. Background technique [0002] A backplane is a motherboard that hosts daughterboards or line cards for custom functionality. At present, in server systems, the backplane design is generally a dedicated design, and different forms of backplanes will be designed according to different installation positions of the backplane. When the server system needs to implement different configurations, it can be solved by redeveloping an applicable new backplane, and splicing multiple backplanes can also be considered. [0003] However, the cost of re-developing a new backplane is high, and splicing multiple backplanes requires a Baseboard Management Controller (BMC) to allocate an I2C interface for each spliced ​​backplane, which will take up too much I2C interface resources.
