and the control part 6 is connected with the switch chip 4 and used for selecting the PCIE channel 2 through the switch chip 4 according to the type of the hard disk accessed by the M.2 slot 5.
It should be noted that the expansion card provided by the present application is applied to a server, and may specifically include a board 1, and XN (N is a preset number of ) gold fingers that are arranged on one side of the board 1, where the XN gold fingers are the th preset number of PCIE lanes 2, and the th preset number of PCIE lanes 2 are used to connect to server lanes on the server, so that the expansion card may be inserted into the server.
Considering that part of the PCIE channels 2 on the extension cannot be detached for use, then PCIE switch chips 3 connected to the PCIE channels 2 of the second preset number (the number set in advance according to the distribution condition of the PCIE channels 2) may be set on the board 1, and may perform a splitting function on the PCIE channels 2 of the second preset number, so as to divide the PCIE channels 2 of the second preset number into channels of the third preset number, where each channel formed by the division includes 4 PCIE channels 2, so that the 4 PCIE channels 2 may be connected to a PCIE X4 hard disk, a PCIE X2 hard disk or a SATA X2 hard disk.
In addition, in order to enable the expansion card to smoothly access the PCIE X4 hard disk, the PCIE X2 hard disk or the SATA X2 hard disk, the switch chip 4, the m.2 slot 5 and the controller 6 connected to the switch chip 4 may be provided. The switch chip 4 is connected to two PCIE channels 2 in the channels, the m.2 slot 5 is connected to the switch chip 4 and two other PCIE channels 2 in the channels (where the two other PCIE channels 2 are two PCIE channels 2 in the channels that are not connected to the switch chip 4), and the control element 6 is configured to select the PCIE channels 2 through the switch chip 4 according to the type of the hard disk accessed by the m.2 slot 5. Considering that different PEDET signals (specifically, 0 and 1 signals) are correspondingly generated when different hard disks are connected to the m.2 card slot, the control element 6 may determine the type of the hard disk connected to the m.2 card slot 5 according to the PEDET signals, and then may correspondingly select the PCIE channel 2 in the channel to be connected to the hard disk through the switch chip 4. Referring to fig. 4, which shows a schematic diagram of a switch chip switching channel provided in the embodiment of the present application, in different situations, the upper four switches or the lower four switches may be correspondingly turned off or turned on, so that the switch chip may be correspondingly connected to a SATA X2 hard disk, a PCIE X2 hard disk, or a PCIE X4 hard disk.
Specifically, when the type of the hard disk accessed by the m.2 slot 5 is the SATA X2 hard disk, the PEDET0 and 1 signals are low signals, and at this time, the switch chip 4 can connect the two PCIE channels 2 connected thereto with the SATA X2 hard disk; when the type of the hard disk accessed by the m.2 slot 5 is a PCIE X2 hard disk, the PEDET0 and 1 signals are high signals, and at this time, the switch chip 4 can also connect the two PCIE channels 2 connected thereto with the SATA X2 hard disk; when the type of the hard disk accessed by the m.2 slot 5 is a PCIE X4 hard disk, the PEDET0 and 1 signals are high signals, and at this time, 4 PCIE channels 2 in the channels are correspondingly connected to the PCIE X4 hard disk. For example: four PCIE channels 2 included in the channel are labeled A, B, C, D (A, B is connected to the switch chip 4), where two pins of the X2 hard disk are a and b, and four pins of the PCIE X4 hard disk are c, d, e, and f, when the expansion card is connected to the X2 hard disk, the switch chip 4 connects A, B to a and b of the X2 hard disk, and when the expansion card is connected to the PCIE X4 hard disk, the switch chip 4 connects A, B to c and d, and C, D to e and f.

According to the technical scheme, the control element, the PCIE switch chip and the switch chip enable the M.2 card slot connected with the 4 PCIE channels in the channel in the expansion card to be connected with the PCIE X4 hard disk, the PCIE X2 hard disk or the SATAX2 hard disk, namely the expansion card can be compatible with the Socket 2 interface and the Socket 3 interface, correspondingly, the expansion card can be inserted into the server to enable the server to be compatible with the Socket 2 interface and the Socket 3 interface, and therefore compatibility of the server is improved.
When the second preset number is smaller than the preset number, the expansion cards provided in the embodiment of the application may further include:
the ocuLink connector 7 is connected with the rest PCIE channels 2 and used for inserting the NVME solid state disk;
the remaining PCIE channels 2 are PCIE channels 2 that are not connected to the PCIE switch chip 3.

The expansion card can also comprise an indicator light (specifically, an LED light) connected with the CPLD, and when the expansion card is inserted into different hard disk types, the indicator light can correspondingly display different colors, so as to prompt a user.
For example, when the number of the channels is 4, the CPLD can be connected with 4 green LED lamps and 4 yellow LED lamps, the green LED lamps are turned on when the expansion card is connected with a hard disk of X2, and the yellow LED lamps are turned on when the expansion card is connected with a hard disk of X4, so that the types of the connected hard disks can be distinguished.
According to the expansion cards provided by the embodiment of the application, the control part 6 can be a switch tube.
A switching tube can also be used as control element 6. Specifically, when the PEDET is a high signal (i.e. 1), the switching tube is turned on, and at this time, the switch chip 4 drags the two PCIE channels 2 connected thereto to the pins of the connected hard disk to connect to the pins of the hard disk; when the PEDET is a low signal (namely 0), the switch tube is disconnected, and at the moment, the switch chip 4 directly connects the two PCIE channels 2 connected with the switch chip to the pins of the hard disk.
