Description

Technical Field

[0001] The present invention relates to the technical field of IT hardware equipment, in particular to the technical field of servers and expansion cards. Background Art

[0002] PCI-Express (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard. Originally named "3GIO," it was proposed by Intel in 2001 as a replacement for the older PCI, PCI-X, and AGP bus standards. PCI-Express utilizes high-speed serial point-to-point dual-channel, high-bandwidth transmission. Connected devices are allocated dedicated channel bandwidth and do not share bus bandwidth. It primarily supports active power management, error reporting, end-to-end reliable transmission, hot-swapping, and Quality of Service (QoS).

[0003] Due to the thickness of the PCIE card itself, two cards need to be stacked one on top of the other in a standard 1U (4.445cm) height server. If a traditional PCIE expansion slot is used, the slot height is too high and there is not enough space on the adapter card (such as the riser card) to set up two PCIE slots to support the two stacked PCIE cards. Summary of the Invention

[0004] In view of the above-mentioned defects of the prior art, the purpose of the present invention is to provide a method for connecting an expansion card, an adapter card module and a server using the same, so as to solve the problem of large space occupation caused by connecting PCIE cards using traditional PCIE expansion slots in the prior art.

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides an adapter card module, which includes: a memory slot connected to the central processing unit of the motherboard, and obtains an adapter signal from the central processing unit; an adapter card, including a circuit board plugged into the memory slot and an adapter slot arranged on the circuit board; the circuit board reads the adapter signal from the memory slot and outputs the adapter signal through the adapter slot, so that the adapter signal is obtained from the adapter slot when an expansion card is plugged into the adapter slot.

[0007] In one embodiment of the present invention, the PCIE slot includes a first PCIE slot and a second PCIE slot.

[0008] In one embodiment of the present invention, the first PCIE slot and the second PCIE slot are located on the same surface of the circuit board, and the first PCIE slot and the second PCIE slot are placed parallel to each other.

[0009] In one embodiment of the present invention, the first PCIE slot and the second PCIE slot are respectively located on the front and back surfaces of the circuit board.

[0010] In one embodiment of the present invention, the memory slot has at least one signal output terminal; the memory slot obtains a transfer signal from the central processing unit and outputs the transfer signal through the signal output terminal; at least one memory connection terminal is provided on the circuit board, and the memory connection terminal is correspondingly connected to the signal output terminal of the memory slot to read the transfer signal from the memory slot.

[0011] In one embodiment of the present invention, the memory connection end is a gold finger.

[0012] In one embodiment of the present invention, the memory slot obtains a sideband signal of a preset function from the central processing unit, and the circuit board obtains the sideband signal from the memory slot and outputs it through the adapter slot.

[0013] An embodiment of the present invention further provides a server, which uses the adapter card module described above.

[0016] 1. The present invention uses a memory slot as an expansion slot. The height of the memory slot is shorter than that of a traditional PCIE expansion slot, so that the width of the riser card can be increased, which can meet the requirement of setting two PCIE slots to support two PCIE cards stacked.

[0037] Example 1

[0038] like Figure 1 As shown, this embodiment provides a riser card module 100 , which includes a memory slot 110 and a riser card 120 .

[0039] In this embodiment, the memory slot 110 is connected to the central processing unit of the motherboard and obtains the adapter signal from the central processing unit; the adapter card 120 includes a circuit board 121 plugged into the memory slot 110 and an adapter slot arranged on the circuit board 121; the circuit board 121 reads the adapter signal from the memory slot 110 and outputs the adapter signal through the adapter slot, so that the adapter signal is obtained from the adapter slot when an expansion card is plugged into the adapter slot.

[0040] Specifically, in this embodiment, the switching signal is preferably, but not limited to, a PCIE signal. To facilitate explanation of the principle of this embodiment, the following embodiment is described by taking the switching signal as a PCIE signal, the switching slot as a PCIE slot, and the expansion card as a PCIE card as an example.

[0041] The circuit board 121 reads the PCIE signal from the memory slot 110 and outputs the PCIE signal through the PCIE slot, so that the PCIE signal is obtained from the PCIE slot when a PCIE card is inserted into the PCIE slot.

[0042] In this embodiment, the memory slot 110 obtains a PCIE signal from a central processing unit of a mainboard. The mainboard is a mainboard in a server. The central processing unit (CPU) can directly access the PCIE device space through CPU addressing to obtain the PCIE signal.

[0043] In this embodiment, the memory slot 110 is connected to the central processing unit (CPU) and obtains the PCIE signal from the CPU. In this way, the memory slot 110 can output the PCIE signal.

[0044] The memory slot 110 has at least one signal output terminal; the memory slot 110 obtains a switching signal from the central processing unit and outputs the switching signal through the signal output terminal.

[0045] Specifically, in this embodiment, the memory slot 110 obtains a PCIE signal from the central processing unit, and outputs the PCIE signal through the signal output end.

[0046] The signal output end of the memory slot 110 is located on the slot, so that the circuit board 121 of the adapter card 120 is connected to the signal output end of the memory slot 110 when plugged into the memory slot 110 .

[0047] In this embodiment, the riser card 120 includes a circuit board 121 and a PCIE slot disposed on the circuit board 121 .

[0048] Specifically, the circuit board 121 is plugged into the memory slot 110 , and the circuit board 121 reads the PCIE signal from the memory slot 110 and outputs the PCIE signal through the PCIE slot, so that the PCIE signal is obtained from the PCIE slot when a PCIE card is plugged into the PCIE slot.

[0049] In this embodiment, if Figure 1 and Figure 2As shown, the PCIE slot includes a first PCIE slot 122 ; or the PCIE slot includes a first PCIE slot 122 and a second PCIE slot 123 .

[0050] That is to say, the PCIE slot may include only one PCIE slot or may include two PCIE slots.

[0051] In this embodiment, when the PCIE slot includes two PCIE slots, the two PCIE slots can be located on the same surface of the circuit board, or can be separately arranged on the front and back surfaces of the circuit board 121, that is, there is a PCIE slot on each of the front and back surfaces of the circuit board 121.

[0052] Specifically, the PCIE slots include a first PCIE slot 122 and a second PCIE slot 123:

[0053] 1) The first PCIE slot 122 and the second PCIE slot 123 are located on the same surface of the circuit board 121 and are arranged vertically parallel to each other;

[0054] 2) The first PCIE slot 122 and the second PCIE slot 123 are respectively located on the front and back surfaces of the circuit board 121, that is, the first PCIE slot 122 is located on the front surface of the circuit board 121, and the second PCIE slot 123 is located on the back surface of the circuit board 121. The first PCIE slot 122 and the second PCIE slot 123 are placed parallel to each other.

[0055] In this embodiment, the PCIE slot includes a first PCIE slot 122 and a second PCIE slot 123, and the first PCIE slot 122 and the second PCIE slot 123 are located on the same surface of the circuit board 121 and are placed parallel to each other.

[0056] In this embodiment, the first PCIE slot 122 is used to insert a first PCIE card, and the second PCIE slot 123 is used to insert a second PCIE card. The first PCIE slot 122 and the second PCIE slot 123 are arranged parallel to each other, so that the inserted first PCIE card and the second PCIE card are arranged parallel to each other.

[0057] like Figure 2 As shown, at least one memory connection terminal 124 is provided on the circuit board 121 , and the memory connection terminal 124 is correspondingly connected to the signal output terminal of the memory slot 110 to read the switching signal from the memory slot 110 .

[0058] Specifically, the memory connection terminal 124 is correspondingly connected to the signal output terminal of the memory slot 110 to read the PCIE signal from the memory slot 110 .

[0059] In this embodiment, the memory connection terminal 124 is a gold finger.

[0060] In addition, in this embodiment, the memory slot 110 obtains a sideband signal of a preset function from the central processing unit, and the circuit board 121 obtains the sideband signal from the memory slot 110 and outputs it through the PCIE slot.

[0061] As described above, this embodiment utilizes the memory slot 110 as an expansion slot. The height of the memory slot 110 is shorter than that of a traditional PCIE expansion slot. This allows the width of the riser card (adapter card 120) to be increased, meeting the requirement of providing two parallel PCIE slots to support two stacked PCIE cards. Furthermore, the memory slot 110 is widely used and inexpensive, offering significant advantages over expensive custom PCIE expansion slots.

[0065] 3) The PCIE card is inserted into the PCIE slot of the adapter card 120 (Riser card), so that the PCIE signal from the CPU passes through the memory slot 110, the adapter card 120 (Riser card), and the PCIE slot to achieve connection with the PCIE card.

[0066] This embodiment also provides a server, such as Figure 4 As shown, the server uses the above-mentioned adapter card module 100. The memory card slot is connected to the CPU of the server motherboard, and the adapter card 120 is inserted into the memory slot 110. The adapter card module 100 has been described in detail above and will not be repeated here.

[0067] If a traditional PCIE expansion slot is used, it is impossible to stack two PCIE cards on top of each other in a 1U server. The solution of this embodiment avoids customized PCIE expansion slots and other high-density connector conversion solutions, reduces costs, and improves the integration within the server.
