Patent ID: 10146729

Abstract:
Embodiments allow an IHS to be configured for different distributions of available PCIe bandwidth. An IHS is reconfigured by utilizing different PCIe riser cards that interface with the PCIe bus of the IHS and route different portions of the available PCIe lanes. PCIe bandwidth may be further distributed using an interposer card that allows a portion of the PCIe bandwidth to be routed to a PCIe device that is supported by the PCIe interposer card. The IHS may be reconfigured by manually switching the riser cards and interposer that are coupled to the IHS. The PCIe distribution is reconfigured without relying on hardware switching components that redirect PCIe lanes. The riser cards and the interposer are coupled to a PCIe baseboard connector of the IHS, where the baseboard connector is divided into two baseboard sub-connectors that each interface with the PCIe bus of the IHS.
