Embodiment
The embodiment of the present application provides a kind of electronic equipment, needs through backboard in order to the line solved in prior art between I/O controller and Switching Module, and the technical matters causing the realization of backboard more complicated.
For making the object of the embodiment of the present application, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly described, obviously, described embodiment is some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
First please refer to Fig. 2, is a kind of structural representation of electronic equipment provided in the embodiment of the present application.As shown in Figure 2, this electronic equipment comprises: backboard; Switching Module, is plugged on described backboard; Wherein, described Switching Module can be connected at least one service controller by described backboard.Input and output (I/O) module, comprises first group of I/O interface and second group of I/O interface, and described I/O module is plugged on described Switching Module by described first group of I/O interface.Described second group of I/O interface can be connected to I/O equipment.Often organize I/O interface and comprise at least one I/O interface.Under normal circumstances, first group of I/O interface only comprises an I/O interface, and second group of I/O interface comprises multiple I/O interface.Described Switching Module is used for providing data retransmission function between described service controller and described I/O module.I/O equipment is such as main frame or hard disk frame.Main frame is such as the main frame of Ethernet interface type or the main frame of fiber channel interface type.I/O module specifically also comprises I/O controller.I/O controller is used between the signal and the signal of all kinds of I/O interface of service controller, do signal conversion, communicates normally between the I/O equipment that service controller and I/O interface so can be made to connect.
Wherein, Switching Module can be connected at least one service controller by described backboard, and specifically, be such as the internal system bus interface that Switching Module is provided by service controller, such as PCIe is connected to service controller.
Further, as shown in Figure 2, direct-connected physically between I/O module and Switching Module, therebetween connection does not need through backboard, so do not need at backboard upward wiring, so therefore the signal wire on backboard reduces, so reduce the complexity of back plate design and realize cost.
Further, because do not need the cabling between backboard deploy I/O module and Switching Module, such as, so at other signal wires of backboard deploy, multiple Switching Module can be increased.Therefore, the extendability of the backboard in the application's scheme is better.
Further, in the application's scheme, an I/O module is only plugged on a Switching Module, so regardless of grafting how many I/O modules on this Switching Module, as long as each service controller provides a group system internal bus by backboard.In prior art, each I/O module is connected to the scheme of two Switching Modules by backboard, further reduces backplane signal, also makes the extendability of the backboard in this programme strengthen.Wherein, internal system bus is connected with service controller for Switching Module.
In practice, I/O module is direct-connected with Switching Module physically can be had but be not limited to following two kinds of forms.
