Problems solved by technology

The disadvantage of this implementation method is that there are two capacitors on the RX link, which will greatly reduce the performance of the link. In addition, there are two sets of motherboard Bom, and the capacitors soldered to the PCB board are different according to different requirements. Card management and control is more complicated, and it is difficult to realize the requirement of using the same board for multiple requirements

Abstract

The invention discloses a PCIe bus switching method based on a server architecture, and relates to server system link optimization technology. A routing line at a PCB of a CPU side goes to a hole at an intermediate position of a PCH end and a PCLe expansion end of a configuration terminal, punching is respectively carried out at leading lines of the PCH end and the PCLe expansion end of the configuration terminal, then a pin-like contact point difference line cable is used, and thus an effect of carrying out cable interconnection at corresponding through holes according to different customer requirements is realized. According to the method, a PCIe bus switching function can be realized according to the different requirements, and an effect of meeting the different requirements of different customers by the same single board of the same product can be guaranteed; the number of devices on the PCB is reduced, and a Bom cost of the PCB is reduced; and at the same time, the routing line ofsignals on the PCB is shortened, losses are reduced, and PCIe bus link performance is improved. The invention also provides a PCIe bus switching device based on the server architecture.

Description

technical field [0001] The present invention relates to server system link optimization technology, specifically a PCIe bus switching device and method based on server architecture. Background technique [0002] Benefiting from the continuous improvement of informatization penetration rate and the rapid development of the Internet industry, China's server market has maintained steady growth.
