Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, in the utility model embodimentTechnical scheme be clearly and completely described, obviously, described embodiment is only thisUtility model part embodiment, instead of whole embodiment. Based in the utility modelEmbodiment, those of ordinary skill in the art obtain under creative work prerequisite not makingEvery other embodiment, belongs to the scope that the utility model is protected.

The utility model embodiment provides a kind of switching board of PCIE signal, as shown in Figure 1,Comprise: CPU (CentralProcessingUnit, central processing unit) 101; With PCIE (PeripheralComponentInterfaceExpress, Peripheral Component Interconnect STD bus) board connects extremelyFew two PCIE connectors 102, and different PCIE connectors 102 and different PCIE plateLink and connect; The first connector 103 being connected with CPU101; Be connected with PCIE connector 102At least two the second connectors 104, and the second different connectors 104 and different PCIEConnector 102 connects; Connecting plate 105. Wherein, one end of connecting plate 105 and the first connector103 connect, in the other end of connecting plate 105 and at least two the second connectors 104 one theTwo connectors 104 connect.

Concrete, in the switching board of PCIE signal, include CPU101 and can process PCIESignal. In the switching board of PCIE signal, include at least two that are connected with PCIE platePCIE connector 102, like this, the switching board of PCIE signal can pass through PCIE connector102 carry out the transmission of PCIE signal. Be, PCIE connector 102 can be by PCIE signalSwitching board in PCIE signal transfer in PCIE board, also can be by PCIE boardIn PCIE signal transfer in the switching board of PCIE signal. And different PCIE connectsConnect device 102 and connect different PCIE boards, that is to say, PCIE connector 102 withA PCIE board connects, and can ensure PCIE signal to transfer to correct PCIE boardIn.

In the switching board of PCIE signal, include the first connector 103 being connected with CPU,At least two the second connectors 104 that are connected with PCIE connector 102, and the second different companiesConnect device 104 and connect from different PCIE connectors 102, that is to say second connector104 are connected with a PCIE connector 102; Connecting plate 105, one end of connecting plate 105 withThe first connector 103 connects, the other end of connecting plate 105 and at least two the second connectors 104In second connector 104 connect. Like this, in the switching board of PCIE signalCPU101 is connected with connecting plate 105 by the first connector 103, the other end of connecting plate 105Can be connected with any PCIE connector 102 by any second connector 104. Like thisOne, in the time that CPU need to switch the PCIE board of communication, the switching board of PCIE signal canBe connected the other end of connecting plate 105 is connected to the PCIE board that need to be switched to CPUThe second connector 104 of connecting of PCIE connector 102, be one end of connecting plate 105Be connected with CPU101 by the first connector 103, the other end of connecting plate 105 and CPUThe second connector 104 that the PCIE connector 102 that needs the PCIE board of communication to connect connectsConnect. Thereby the PCIE signal that CPU101 can be processed passes by the first connector 103Transport to connecting plate 105, and transfer to the second connector 104 by connecting plate 105, and by secondConnector 104 transfers to PCIE connector 102, transfers to PCIE by PCIE connector 102Board. Or, the PCIE signal in PCIE board can be connected by the PCIE of its connectionConnect that in the switching board that device 102 transfers to PCIE signal, this PCIE connector 102 connectsTwo connectors 104.

Like this, can pass through to connect by the switching board of the PCIE signal in the utility modelThe PCIE board that fishplate bar connects CPU switches to the PCIE board that it need to connect, and connectsFishplate bar is only that the second connector that carries out the transmission of PCIE signal with need is connected, without with allTwo connectors connect, and have therefore reduced the wiring on the switching board of PCIE signal, have reducedThe design difficulty of the board at CPU place. And, on the switching board of PCIE signal without establishingMeter PCIE switch, has reduced manufacturing cost.

Further, as shown in Figure 2, the first connector 103 is Oculink (Optical/CopperLink, the link of fiber/copper cable) connector. The second connector 104 is Oculink connector. ConnectFishplate bar 105 is fiber/copper cable link cable Oculinkcable.

It should be noted that, in the utility model, the first connector 103 can also be otherThe connector of type, the second connector 104 can also be the connector of other types, and connectsPlate 105 can also be the connecting plate of other types, and the utility model does not limit this.

Further, as shown in Figure 3, at least two PCIE connectors 102 comprise: forPCIEMEZZ (Mezzanine, intermediate layer connector) links the MEZZ connector connecing; WithIn linking with I/O (Input/Output, input/output end port) PCIE the I/O connector connecing.

Concrete, in the time that PCIE board is PCIEMEZZ card and I/OPCIE card, at PCIELinking with PCIEMEZZ the PCIE connector 102 connecing and be in the switching board of signalMEZZ connector. In the switching board of PCIE signal, link with I/OPCIE the PCIE connecingConnector 102 is I/O connector.

Further, as shown in Figure 4, CPU101 is that the PCIE of 8 is total by data bit widthLine is connected with the first connector 103, and the second connector 104 is the PCIE of 8 by data bit widthBus and PCIE connector 102.

The utility model embodiment provides a kind of switching board of PCIE signal, comprising: CPU,At least two PCIE connectors that are connected with PCIE board, and different PCIE connectors withDifferent PCIE boards connects; The first connector being connected with CPU; Connect with PCIE connectorAt least two the second connectors that connect, and the second different connectors and different PCIE connectorConnect; Connecting plate; Wherein, one end of connecting plate is connected with the first connector, connecting plate anotherOne end is connected with second connector at least two the second connectors. Like this, at PCIEIn the switching board of signal, include the first connector and be connected with CPU, at least two second connectConnect device and be connected with PCIE plate, one end of connecting plate is connected with the first connector, the other end with at leastA connection in two the second connectors. Thereby can, in the time that needs switch PCIE plate, pass throughConnecting plate changes the second connector connecting, and then the PCIE signal that CPU can be sent passesTransport to corresponding PCIE plate. And connecting plate is only to carry out of PCIE signal transmission with needTwo connectors connect, and without being connected with the second all connectors, have therefore reduced PCIE signalSwitching board on wiring, reduced the design difficulty of the board at CPU place. And,On the switching board of PCIE signal, without design PCIE switch, reduce manufacturing cost.
