Abstract

The application provides an electronic device. The electronic device comprises a back panel, switching modules and input / output (I / O) modules; the switching modules are plugged in the back panel; the switching modules can be connected to at least one business controller through the back panel; each input / output (I / O) module comprises a first group of I / O interfaces and a second group of I / O interfaces; the input / output (I / O) modules are plugged in the switching modules through the first group of I / O interfaces; the second group of I / O interfaces can be connected to an I / O device; the switching modules are used for providing a data forwarding function between the business controllers and the input / output (I / O) modules. Since the input / output (I / O) modules are directly connected with the switching modules without the back panel, signals on the back panel are reduced, the implementation complexity of the back panel is deceased, and the cost of the back panel is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an electronic device. Background technique [0002] In existing electronic devices, especially in storage systems, many input / output (I / O) interfaces are involved. The I / O interface is used to connect a host or a hard disk frame. The I / O interface is provided on one side of the I / O controller. The I / O interface needs to be connected to the service controller through the I / O controller. The other side of the I / O controller is usually connected to the service controller through a system internal bus interface provided by the service controller, such as Peripheral Component Interconnect Express (English: Peripheral Component Interconnect Express, PCIe for short). Because the types of I / O interfaces are diversified and the types of connected devices are also diversified, the I / O controller is used to perform signal conversion between PCIe signals and signals of vario...
