[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] When the main chip is connected to a hard disk, if an adapter board with an integrated conversion chip is not used, the main chip cannot be compatible with hard disks supporting different interfaces; if an adapter board with an integrated conversion chip is used, different adapter boards need to be redesigned to adapt to hard disks with different interfaces, resulting in a high connection cost. The prior art provides a structure for realizing processor adaptive SATA and NVME (Non-Volatile Memory express, non-volatile memory host controller interface specification) M.2. Figure 1 It is a circuit diagram of the structure of realizing processor adaptive SATA and NVME M.2 provided by the prior art, such as Figure 1As shown, two PCIE signals are output by the processor, one of which is directly output to the channel port of the channel selection unit, and the other PCIE signal is converted into a SATA signal through a PCIE to SATA bridge, and the converted SATA signal is output to the channel port of the channel selection unit, and the corresponding channel is opened for adaptation according to the actual access signal protocol type. The structure for implementing the processor adaptive SATA and NVME M.2 provided above can adapt the corresponding signal to the SSD (Solid State Disk or Solid State Drive, solid state hard disk) of the protocol type inserted into the M.2 connector. However, there is a physical interaction between the SATA signal and the PCIE signal on the interface of the M.2 connector, and the M.2 connector can only adapt to the SATA protocol or the PCIE protocol, depending on the protocol of the SSD connected. Secondly, the processor outputs multiple PCIE signals for subsequent channel selection, which will occupy more processor resources. At the same time, if an SSD connected to the PCIE protocol is not used after one of the PCIE signals is converted into a SATA signal, the processor resources are wasted.

[0029] Therefore, in order to solve the above problems, the present invention provides a hard disk compatible conversion module. Figure 2 This is one of the structural diagrams of the hard disk compatible conversion module provided by the embodiment of the utility model. Figure 2 As shown, the hard disk compatible conversion module 100 includes: a U.2 connector 130, a channel selection switch 110 and a conversion component 120, wherein:

[0030] The U.2 connector 130 is connected to a hard disk, and the U.2 connector 130 is used to generate a hard disk signal based on the type of the hard disk.

[0031] The channel selection switch 110 is respectively connected to the U.2 connector 130 and the conversion component 120. The channel selection switch 110 is used to transmit the PCIE signal and generate a channel control signal and a conversion enable signal based on the level state of the hard disk signal. The channel control signal is used to determine the target transmission channel corresponding to the PCIE signal; the target transmission channel is the first channel B connected to the conversion component 120 in the channel selection switch 110 or the second channel C connected to the U.2 connector 130.

[0032] The conversion component 120 is connected to the U.2 connector 130; the conversion component 120 is used to convert the PCIE signal into a SATA signal based on the level state of the conversion enable signal when the target transmission channel is the first channel B connected to the conversion component 120.

[0033] Specifically, in the embodiment of the utility model, the hard disk is connected through the U.2 connector 130. Since the U.2 connector 130 supports both hard disks of the SATA protocol and hard disks of the PCIE protocol, the hard disk compatible conversion module 100 can be connected to both hard disks of the SATA protocol and hard disks of the PCIE protocol, thereby improving the compatibility of the hard disk compatible conversion module 100. After the hard disk is connected to the U.2 connector 130, the U.2 connector 130 can generate a hard disk signal according to the type of the hard disk, and identify the type of the hard disk by the level state of the hard disk signal. For example, if the hard disk signal is a high level signal, it indicates that the type of the hard disk is a hard disk that supports the SATA protocol. If the hard disk signal is a low level signal, it indicates that the type of the hard disk is a hard disk that supports the PCIE protocol. Afterwards, the U.2 connector 130 transmits the hard disk signal to the channel selection switch 110.

[0034] The channel selection switch 110 is connected to the U.2 connector 130 and the conversion component 120 respectively. After the channel selection switch 110 receives the PCIE signal and the hard disk signal transmitted by the U.2 connector 130, the type of the hard disk connected to the U.2 connector 130 can be determined by the level state of the hard disk signal. After that, a channel control signal is generated according to the type of the hard disk. According to the level state of the channel control signal, the target transmission channel for outputting the PCIE signal can be determined from the first channel B and the second channel C of the channel selection switch 110, so as to output the PCIE signal to the conversion component 120 through the first channel B, or output the PCIE signal to the U.2 connector 130 through the second channel C. For example, if the hard disk signal is a high-level signal, the type of hard disk connected to the U.2 connector 130 is a hard disk that supports the SATA protocol, and the channel control signal is a high-level signal, then the target transmission channel is the first channel B, and the channel selection switch 110 can output the PCIE signal through the first channel B to the conversion component 120 for signal conversion; if the hard disk signal is a low-level signal, the type of hard disk connected to the U.2 connector 130 is a hard disk that supports the PCIE protocol, and the channel control signal is a low-level signal, then the target transmission channel is the second channel C, and the channel selection switch 110 can output the PCIE signal through the second channel C to the U.2 connector 130.

[0035] At the same time, the channel selection switch 110 can also generate a conversion enable signal and send the conversion enable signal to the conversion component 120. According to the level state of the conversion enable signal, it can be determined whether the conversion component 120 converts the PCIE signal into a SATA signal. For example, if the target transmission channel is the first channel B, the conversion enable signal is a high-level signal. After the conversion component 120 receives the PCIE signal through the first channel B, it can convert the PCIE signal into a SATA signal and transmit the converted SATA signal to the U.2 connector 130 to achieve adaptation with a hard disk supporting the SATA protocol; if the target transmission channel is the second channel C, the conversion enable signal is a low-level signal, the first channel B is turned off, and the conversion component 120 cannot transmit the PCIE signal, and thus cannot convert the PCIE signal. At this time, the channel selection switch 110 can directly transmit the PCIE signal to the U.2 connector 130 through the second channel C to achieve adaptation with a hard disk supporting the PCIE protocol. That is, no matter whether the U.2 connector 130 is connected to a hard disk that supports the SATA protocol or a hard disk that supports the PCIE protocol, the hard disk compatibility conversion module 100 provided in the embodiment of the utility model can be used to achieve adaptation with the connected hard disk, thereby improving compatibility with hard disks with different interfaces and reducing connection costs.

[0036] It should be noted that the above-mentioned channel control signal and the conversion enable signal assist each other to ensure that there is only one signal between the channel selection switch 110 and the U.2 connector 130, avoid mutual interference between the two signals, and ensure the normal operation of the hard disk compatible module. That is, when the channel control signal is a high-level signal, the target transmission channel is the first channel B, and when the first channel B is turned on and the second channel C is turned off, the conversion enable signal is a high-level signal, and the conversion component 120 can convert the PCIE signal output by the target transmission channel into a SATA signal. At this time, there is only a SATA signal in the hard disk compatible conversion module 100, and the hard disk supporting the SATA protocol is adapted. When the channel control signal is a low-level signal, the target transmission channel is the second channel C, and when the second channel C is turned on and the first channel B is turned off, the conversion enable signal is a low-level signal. Based on the channel control signal and the conversion enable signal, the conversion component 120 is double-guaranteed to be unable to perform signal conversion, ensuring that there is only a PCIE signal in the hard disk compatible conversion module 100 at this time, and the hard disk supporting the PCIE protocol is adapted.

[0037] It should be noted that the U.2 connector 130 is also called SFF-8639. The interface of the U.2 connector 130 combines the features of the SATA and SAS interfaces. The U.2 connector 130 not only supports the SATA-Express specification, but is also compatible with SAS (Serial Attached SCSI) and SATA specifications. The theoretical bandwidth of the U.2 connector 130 reaches 32 Gbps.

[0038] In addition, the U.2 connector 130 includes two groups of pins, one group of pins is used to transmit and process SATA signals, and the other group of pins is used to transmit and process PCIE signals. The two groups of pins are independent of each other, so that the SATA signals and PCIE signals in the U.2 connector 130 are physically independent of each other, and there is no conversion or influence between them.

[0039] It should be noted that PCIE is a high-speed serial computer expansion bus standard, which belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices have exclusive channel bandwidth, do not share bus bandwidth, and have high data transmission rate.

[0040] Optionally, the channel selection switch may be a high-speed channel two-to-one analog switch.

[0041] Furthermore, a slot is provided on the U.2 connector 130 , the presence detection pin PERST is provided in the slot, and the hard disk is inserted in the slot.

[0042] Specifically, a slot is provided on the U.2 connector 130, that is, the U.2 connector 130 can only connect one hard disk, and the hard disk can be a hard disk supporting the SATA protocol, or a hard disk supporting the PCIE protocol. A position detection pin PERST is provided in the slot, and the position detection pin PERST in the U.2 connector 130 matches the position of the position detection pin of the hard disk of one of the interfaces. For example, taking the hard disk that matches the position of the position detection pin PERST in the U.2 connector 130 as a hard disk supporting the PCIE protocol, and the position detection signal inside the hard disk of the PCIE protocol is a low-level signal, and the hard disk signal defaults to a high-level signal as an example, after the hard disk of the PCIE protocol is plugged into the slot of the U.2 connector 130, the position detection pin inside the hard disk of the PCIE protocol is connected to the position detection pin PERST of the U.2 connector 130, then the position detection signal inside the hard disk of the PCIE protocol can pull down the level of the position detection pin PERST in the U.2 connector 130, that is, pull down the hard disk signal from a high-level signal to a low-level signal. For another example, taking the case where the hard disk that matches the position of the presence detection pin PERST in the U.2 connector 130 is a SATA protocol hard disk, after the SATA protocol hard disk is inserted into the slot of the U.2 connector 130, there is no presence detection pin in the SATA protocol hard disk that matches the presence detection pin PERST of the U.2 connector 130, then the hard disk signal corresponding to the presence detection pin PERST of the U.2 connector 130 is still a high-level signal.

[0043] Furthermore, if Figure 2 As shown, the second channel C of the channel selection switch 110 is connected to the second end of the U.2 connector 130 , and the selection pin SEL of the channel selection switch 110 is connected to the presence detection pin PERST of the U.2 connector 130 .

[0044] Specifically, the second channel C in the channel selection switch 110 is directly connected to the second end of the U.2 connector 130, that is, when the target transmission channel is the second channel C, it indicates that the type of the hard disk connected to the U.2 connector 130 is a hard disk of the PCIE protocol, and the channel selection switch 110 can transmit the received PCIE signal to the U.2 connector 130 through the second channel C to achieve adaptation with the hard disk of the PCIE protocol. In addition, the selection pin SEL of the channel selection switch 110 is connected to the in-place detection pin PERST of the U.2 connector 130. After the hard disk is inserted into the slot of the U.2 connector 130, the U.2 connector 130 can generate a hard disk signal through the in-place detection pin PERST, and transmit the hard disk signal to the selection pin SEL of the channel selection switch 110, so that the channel selection switch 110 can judge the type of hard disk connected to the U.2 connector 130 based on the level state of the hard disk signal.

[0045] Further, Figure 3 This is a second structural diagram of the hard disk compatible conversion module provided by the embodiment of the utility model. Figure 3 As shown, the conversion component 120 includes a PCIE to SATA chip 122, wherein:

[0046] The input end of the PCIE to SATA chip 122 is connected to the first channel B of the channel selection switch 110, the power end of the PCIE to SATA chip 122 is connected to the enable end EN of the channel selection switch 110, and the output end of the PCIE to SATA chip 122 is connected to the first end of the U.2 connector 130.

[0047] Specifically, the conversion component 120 may include a PCIE to SATA chip 122, and the channel selection switch may generate a conversion enable signal according to the level state of the hard disk signal, and send the conversion enable signal to the power supply end of the PCIE to SATA chip 122 through the enable end EN, and control the working state of the PCIE to SATA chip 122 through the level state of the conversion enable signal, that is, control whether the PCIE to SATA chip 122 performs signal conversion. For example, if the conversion enable signal is a high-level signal, the PCIE to SATA chip 122 may be controlled to convert the PCIE signal to a SATA signal, and if the conversion enable signal is a low-level signal, the PCIE to SATA chip 122 may be controlled to stop working. After the PCIE to SATA chip 122 performs signal conversion, the converted SATA signal may be transmitted to the first end of the U.2 connector 130 through the output end to achieve adaptation with a hard disk supporting the SATA protocol.

[0048] Further, Figure 4 This is the third structural diagram of the hard disk compatible conversion module provided by the embodiment of the utility model, such as Figure 4 As shown, the conversion component 120 also includes a power supply unit 121, the enable end of the power supply unit 121 is connected to the enable end EN of the channel selection switch 110, and the output end of the power supply unit 121 is connected to the power end of the PCIE to SATA chip 122; the power supply unit 121 is used to supply power to the PCIE to SATA chip 122 based on the level state of the conversion enable signal.

[0049] Specifically, the conversion component 120 may include a power supply unit 121 and a PCIE to SATA chip 122, the enable end of the power supply unit 121 is connected to the enable end EN of the channel selection switch 110, and the channel selection switch 110 may generate a conversion enable signal according to the level state of the hard disk signal, and send the conversion enable signal to the enable end of the power supply unit 121 through the enable end EN, and control the power supply unit 121 to supply power to the PCIE to SATA chip 122 through the level state of the conversion enable signal. For example, if the conversion enable signal is a high-level signal, the power supply unit 121 may open the output end to supply power to the power supply end of the PCIE to SATA chip 122. If the conversion enable signal is a low-level signal, the power supply unit 121 cannot supply power to the power supply end of the PCIE to SATA chip 122. In addition, after the PCIE to SATA chip 122 receives the conversion enable signal as a high-level signal, and the channel selection switch 110 transmits the PCIE signal to the PCIE to SATA chip 122 through the first channel B, the PCIE to SATA chip 122 can convert the PCIE signal into a SATA signal, and transmit the converted SATA signal to the first end of the U.2 connector 130, thereby achieving adaptation to a hard disk that supports the SATA protocol.

[0050] Furthermore, the power supply unit 121 includes a power chip or a power switch.

[0051] Specifically, when the power supply unit 121 is a power chip, if the conversion enable signal is a high-level signal, the power supply output function of the power chip can be activated, that is, the PCIE to SATA chip 122 is powered on based on the power supply voltage output by the power chip, so that the PCIE to SATA chip 122 is in a normal working state, and the PCIE to SATA chip 122 performs signal conversion on the PCIE signal. If the conversion enable signal is a low-level signal, the power supply output function of the power chip is not activated, and the PCIE to SATA chip 122 is in a power-off state, and the PCIE signal cannot be converted.

[0052] When the power supply unit 121 is a power switch, the switch state of the power switch can be controlled according to the level state of the conversion enable signal, thereby controlling the on-off state between the enable end EN of the channel selection switch 110 and the PCIE to SATA chip 122, and further controlling the working state of the PCIE to SATA chip 122. For example, if the conversion enable signal is a high-level signal, the power switch can be controlled to be in a closed state, so that the path between the channel selection switch 110 and the PCIE to SATA chip 122 is turned on, so that the channel selection switch 110 supplies power to the PCIE to SATA chip 122, so that the PCIE to SATA chip 122 is in a normal working state, and then the PCIE to SATA chip 122 performs signal conversion on the PCIE signal. If the conversion enable signal is a low-level signal, the power switch can be controlled to be in an off state, so that the path between the channel selection switch 110 and the PCIE to SATA chip 122 is disconnected, so that the PCIE to SATA chip 122 is in a power-off state, so that the PCIE to SATA chip 122 cannot perform signal conversion on the PCIE signal.

[0053] The hard disk compatible conversion module provided by the utility model is respectively connected to a hard disk, a channel selection switch and a conversion component through a U.2 connector, and the channel selection switch is connected to the conversion component, the U.2 connector generates a hard disk signal according to the type of the connected hard disk, the channel selection switch judges the type of the connected hard disk according to the level state of the hard disk signal, and generates a corresponding channel control signal and a conversion enable signal, and according to the level state of the channel control signal, determines the target transmission channel of the PCIE signal from a first channel B connected to the conversion component and a second channel C connected to the U.2 connector, if the connected hard disk is a hard disk supporting the PCIE protocol, the second channel C is used as the target transmission channel, and the PCIE signal is transmitted to the U.2 connector, so as to achieve adaptation with the hard disk supporting the PCIE protocol; if the connected hard disk is a hard disk of the SATA protocol, the first channel B is used as the target transmission channel, and the conversion component converts the PCIE signal into a SATA signal according to the level state of the conversion enable signal, so as to achieve adaptation with the hard disk supporting the SATA protocol, thereby improving the compatibility of hard disks adapted to different interfaces and reducing the connection cost at the same time.

[0054] The utility model also provides a server. Figure 5 Schematic diagram of the structure of the server provided by the embodiment of the utility model, such as Figure 5 As shown, the server 200 includes a main chip 210 and a hard disk compatible conversion module 100 as described in any one of the above items, the main chip 210 is connected to the channel selection switch in the hard disk compatible conversion module 100, and the main chip 210 is used to output a PCIE signal to the channel selection switch.

[0055] Specifically, the server 200 can be understood as any server 200 with expansion requirements, for example, the server 200 can be a storage server 200. The server 200 can be connected to the main chip 210, and the main chip 210 outputs a PCIE signal to the hard disk compatible conversion module 100, and the hard disk compatible conversion module 100 converts the PCIE signal as needed according to the type of the hard disk 220. Compared with the processor outputting multiple PCIE signals in the prior art, the embodiment of the utility model occupies less resources of the main chip 210. At the same time, in the embodiment of the utility model, according to the type of the connected hard disk 220, the PCIE signal is converted into a SATA signal corresponding to the type of the hard disk 220, or the PCIE signal is transmitted to the hard disk 220, so as to achieve the adaptation of the main chip 210 and the hard disk 220, and avoid the unused PCIE signal in the prior art, thereby causing the waste of resources of the main chip 210. In addition, currently, when the general server 200 uses an adapter board to expand the hard disk 220, the slot part of the adapter board also has only one PCIE signal. In the embodiment of the utility model, the main chip 210 outputs one PCIE signal, which is more in line with the expansion standard of the general server 200.

[0056] Optionally, the main chip 210 may be a central processing unit (CPU) or a micro controller unit (MCU), etc., which is not limited in the embodiment of the utility model.

[0057] Further, the server 200 further includes a hard disk 220, and the hard disk 220 is connected to the U.2 connector in the hard disk compatible conversion module 100. The protocol of the hard disk 220 complies with the protocol supported by the U.2 connector, that is, the hard disk 220 may include a hard disk 220 supporting the SATA protocol or a hard disk 220 supporting the PCIE protocol.

[0058] Optionally, the hard disk 220 is a solid state drive. The solid state drive uses flash memory technology, so that the data reading and writing speed of the solid state drive is much higher than that of the mechanical hard disk, which improves the operating performance of the server 200 such as system startup, software loading and file transfer, thereby improving the overall system performance of the server 200. Secondly, there are no mechanical moving parts in the solid state drive, which can better resist vibration and impact, thereby protecting data security. At the same time, the solid state drive consumes less power, which helps to extend the battery life. In addition, the solid state drive generates less noise when working, which can meet the use requirements of a low-noise environment.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
