PCIe equipment physical lane combination system and method

Abstract

The invention discloses a PCIe equipment physical lane combination system. The PCIe equipment physical lane combination system comprises an upper computer and a control device. The upper computer generates lane configuration information representing a lane combination mode between the two interfaces according to a lane combination demand between the non-standard PCIe interface and the standard PCIe interface and sends the lane configuration information to the control device; and the control device combines the lane of the non-standard PCIe interface and the lane of the standard PCIe interfaceaccording to the lane configuration information so as to realize the communication connection of the two interfaces. Visibly, according to the method and the device, the lane free combination of the non-standard PCIe interface and the standard PCIe interface can be realized, so that the development and design of customized PCIe interface connection equipment are facilitated. The invention furtherdiscloses a PCIe equipment physical lane combination method which has the same beneficial effects as the PCIe equipment physical lane combination system.

Description

technical field [0001] The invention relates to the field of PCIe equipment, in particular to a system and method for combining physical lanes of PCIe equipment. Background technique [0002] PCIe (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard. At present, because the PCIe bus has the advantages of high speed, good fault tolerance, and convenient expansion, most server systems use the PCIe bus to expand peripherals. In the prior art, the interface sequence and physical form of PCIe devices are usually standard, but when designing PCIe interfaces in server systems, sometimes non-standard slots may exist. If PCIe devices with standard interfaces are to be connected in this case, usually The technical means adopted is to convert the interface through the riser card. However, in this connection mode, the physical lane (link) combination of the non-standard PCIe interface and the standard PCIe interface is fixed, which is not ...
