[0002] In a computer system, storage is an essential component. In order to ensure the stability of the signal during transmission, the motherboard usually detects the in-place status of the storage component.

[0003] At present, when the mainboard performs in-place status detection on multiple hard disks on the backplane, the chip on the mainboard is directly connected to the chip on the backplane, and the chip on the mainboard needs to directly send multiple detection signals corresponding to each hard disk to the chip on the backplane, and when the chip on the backplane receives the multiple detection signals, it performs in-place status detection on each hard disk on it according to the instructions of each detection signal.

[0004] However, when a large number of hard disks are included on the backplane, the existing detection circuit is relatively complex, resulting in a high detection cost. Summary of the invention

[0005] Based on this, it is necessary to provide a detection device and a detection method that can simplify the detection circuit structure in order to solve the above technical problems.

[0006] In a first aspect, the present application provides a detection device, which includes an encoding circuit, a decoding circuit and a control unit;

[0009] The control unit is used to detect the hard disk on the backplane according to multiple decoding signals to obtain a detection result.

[0010] The detection device provided in the embodiment of the present application integrates multiple detection signals output by the signal unit through an encoding circuit, and restores the integrated signal through a decoding circuit, so that the control unit can detect multiple hard disks based on the multiple detection signals. When the number of hard disks is relatively large, the detection device can greatly reduce the number of signal lines, that is, greatly simplify the signal transmission lines of the circuit, and thus can reduce the detection cost of the detection device to a certain extent; in addition, it can also reduce the crosstalk problem between multiple groups of signal lines, thereby improving the accuracy of the test.

[0011] In one of the embodiments, the control unit includes a logic control subunit and a detection subunit;

[0012] The logic control subunit is used to determine the hard disk in place according to the in-place status information of each hard disk on the backplane;

[0013] The detection subunit is used to perform status detection on the hard disk in place according to multiple decoding signals to obtain a detection result.

[0014] The detection device provided in the embodiment of the present application can detect the working status of each hard disk by setting up a detection subunit. Compared with the traditional device that can only detect the presence of the hard disk, the above device can perform a comprehensive detection of the hard disk. In addition, assigning the detection of the hard disk to the detection subunit can reduce the working pressure of the control unit and further improve the test efficiency.

[0022] The encoding circuit is specifically used to integrate the integration signal and the detection signal except for part of the detection signal to obtain the target detection signal.

[0023] The detection device provided by the embodiment of the present application can effectively save the number of pins of the encoding circuit by integrating the signal through the integration circuit. In particular, when it is necessary to perform status detection on multiple hard disks, since the number of pins of the encoding circuit is limited, the method of first integrating the signal by the integration circuit can significantly reduce the number of required pins. The above detection method can improve the scalability and flexibility of the system while reducing the complexity of the system. In addition, after the signal is integrated by the integration circuit, the integrated signal is sent to the encoding circuit, which can more efficiently perform data transmission and status detection.

[0024] In one embodiment, the detection device further includes a signal interface; the encoding circuit sends the target detection signal to the decoding circuit via the signal interface.

[0025] The detection device provided in the embodiment of the present application transmits the target detection signal to the decoding circuit through a very small number of signal interfaces, thereby solving the problem of complex circuit structure caused by the traditional use of multiple signal transmission lines. When the number of hard disks is relatively large, the detection device can greatly reduce the number of signal lines, that is, greatly simplify the signal transmission lines of the circuit, thereby reducing the detection cost of the detection device to a certain extent.

[0026] In a second aspect, the present application further provides a detection method, which is applied to the detection device of any embodiment of the first aspect, and the method comprises:

[0027] The hard disk is tested according to a plurality of decoding signals output by the decoding circuit to obtain a test result.

[0028] The detection method provided in the embodiment of the present application detects the hard disk according to the multiple decoding signals output by the decoding circuit to obtain the detection result. The above detection method integrates the multiple detection signals output by the signal unit through the encoding circuit, and the decoding circuit restores the integrated signal, so that the control unit can detect multiple hard disks based on the multiple detection signals. When the number of hard disks is relatively large, the detection device can greatly reduce the number of signal lines, that is, greatly simplify the signal transmission line of the circuit, and thus reduce the detection cost of the detection device to a certain extent; in addition, it can also reduce the crosstalk problem between multiple groups of signal lines, thereby improving the accuracy of the test.

[0029] In one embodiment, the hard disk is tested according to a plurality of decoding signals output by the decoding circuit to obtain a test result, including:

[0030] The hard disk in place is determined according to the in-place status information of each hard disk on the backplane, and the status of the hard disk in place is detected according to multiple decoding signals to obtain the detection result.

[0031] The detection method provided in the embodiment of the present application can not only detect the presence of the hard disk, but also detect the working status of the hard disk.

[0036] In one embodiment, the method further comprises:

[0037] Turn on the indicator lights of the hard disks in place according to the test results.

[0038] The detection method provided in the embodiment of the present application, since the state of the indicator light can reflect the different states of the hard disk, by connecting the indicator light to the hard disk, there is no need to enter the hard disk management interface.

[0064] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0067] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0068] In the server system, storage is an indispensable part of the device. In order to ensure the stability of the signal during the transmission process, the mainboard in the server usually detects the in-place status of the storage component. At present, in the process of the mainboard detecting the in-place status of multiple hard disks on the backplane, the chip on the mainboard is directly connected to the chip on the backplane, and the chip on the mainboard needs to directly send the multi-channel detection signal corresponding to each hard disk to the chip on the backplane, and when the chip on the backplane receives the multi-channel detection signal, it detects the in-place status of each hard disk on it according to the indication of each detection signal. However, when the backplane includes a large number of hard disks, the connection method of the existing detection circuit requires more wired cables to support the transmission of the signal. There are often as many as ten interface connections between the backplane and the mainboard. The structure of the detection circuit is very complicated, resulting in high detection costs, and the cumbersome connection method may cause line connection errors, or the signal quality deteriorates due to crosstalk between lines.

[0069] The present application provides a detection device and a detection method, aiming to solve the above-mentioned technical problems. The following embodiments will specifically illustrate the detection device and the detection method described in the present application.

[0070] In one embodiment, Figure 1 As shown, a detection device 1 is provided, which includes an encoding circuit 101, a decoding circuit 201 and a control unit 202.

[0071] Among them, the encoding circuit 101 is used to integrate multiple detection signals output by the signal unit 102 on the main board 10 to obtain a target detection signal; the decoding circuit 201 is used to decode the target detection signal to obtain multiple decoding signals; the control unit 202 is used to detect the hard disk 204 on the backplane 20 according to the multiple decoding signals to obtain a detection result.

[0072] The encoding circuit 101 can be arranged on the mainboard 10 to integrate or merge the input multiple signals. Optionally, the encoding circuit 101 can also be arranged separately and connected to the mainboard 10. The decoding circuit 201 can be arranged on the backplane 20 to decode or restore the input integrated signal or merged signal to decode or restore multiple signals. Optionally, the decoding circuit 201 can also be arranged separately and connected to the backplane 20. The signal unit 102 includes a control chip and a baseboard management controller. The control chip can be a south bridge chip (Platform Controller Hub, referred to as PCH), which is used to control the signal transmission and processing between the components on the mainboard 10. The baseboard management controller can be a baseboard management controller (Baseboard Management Controller, referred to as BMC) conventionally set on the mainboard of a server. The hard disk 201 includes at least one of an NVME disk, a SATA disk, and a SAS disk, and multiple hard disks 201 can be arranged on the backplane, as well as multiple hard disks 201 of the same type or different types.

[0073] The detection signal is a signal required to detect the hard disk 204, and is sent by the control chip and the baseboard management controller. The detection signal may specifically include an in-place state detection signal and a working state detection signal. The detection result includes that the hard disk 204 is in a normal state, or that the hard disk 204 is in an abnormal state. The detection result may specifically include an in-place state detection result and a working state detection result. When detecting whether the hard disk 204 is in place, the in-place state detection result specifically includes that the hard disk 204 is in place, or that the hard disk 204 is not in place; when detecting the working state of the in-place hard disk 204, the working state detection result includes that the hard disk 204 is in a normal working state, or that the hard disk 204 is in an abnormal working state.

[0074] The working principle of the detection device described in the embodiment of the present application is: Figure 1When the detection device shown detects the status of each hard disk 204 on the backplane 20, the signal unit 102 on the mainboard 10 can send multiple detection signals to the encoding circuit 101. After receiving the multiple detection signals, the encoding circuit 101 can integrate the multiple detection signals to obtain a target detection signal, and then send the target detection signal to the decoding circuit 201. After receiving the target detection signal, the decoding circuit 201 can decode or restore the integrated target detection signal to obtain multiple decoded signals, and send the multiple decoded signals to the control unit 202. After receiving the multiple decoded signals, the control unit 202 can first detect the in-place status of each hard disk 204 according to the in-place status detection signal, and when it is determined that there is a hard disk 204 in place, the control unit 202 then detects the working status of the hard disk 204 in place according to the working status detection signal to obtain a detection result.

[0075] Optionally, the control unit 202 can detect the in-place status of each hard disk 204 according to the in-place status detection signal. The process can be as follows: the control unit 202 extracts the hard disk 204 identifier from the in-place status detection signal, and then determines the hard disk 204 to be detected according to the hard disk 204 identifier, and reads the in-place status data of the hard disk 204 to be detected, and determines whether the hard disk 204 to be detected is in place according to the in-place status data. If the in-place status data meets the preset in-place requirements, it is determined that the hard disk 204 is in place; if the in-place status data does not meet the preset in-place requirements, it is determined that the hard disk 204 is not in place. For example, assuming that the value of the in-place status data is 1, it is considered to be in place, and the value of the in-place status data is 0, it is considered to be not in place. The above method can obtain an in-place status detection result including whether the hard disk 204 is in place.

[0076] Optionally, the process of the control unit 202 detecting the working status of the hard disk 204 in place according to the working status detection signal can be: the control unit 202 can determine the control instruction according to the working status detection signal, and send the control instruction to the hard disk 204 in place to control it to work, and then read the working status data of the hard disk 204, and determine whether the hard disk 204 is working normally according to the working status data; if the working status data indicates that the hard disk 204 is working normally, it is determined that the hard disk 204 is in a normal working state; if the working status data indicates that the hard disk 204 is working abnormally, it is determined that the hard disk 204 is in an abnormal working state, thereby obtaining a working status detection result including whether the hard disk 204 is in a normal working state.

[0077] The detection device provided in the embodiment of the present application integrates multiple detection signals output by the signal unit through an encoding circuit, and restores the integrated signal through a decoding circuit, so that the control unit can detect multiple hard disks based on the multiple detection signals. When the number of hard disks is relatively large, the detection device can greatly reduce the number of signal lines, that is, greatly simplify the signal transmission lines of the circuit, and thus can reduce the detection cost of the detection device to a certain extent; in addition, it can also reduce the crosstalk problem between multiple groups of signal lines, thereby improving the accuracy of the test.

[0078] In one embodiment, a detection device 1 is also provided, such as Figure 2 As shown, in Figure 1 On the basis of the detection device 1 described in the embodiment, the control unit 202 in the detection device 1 includes: a logic control subunit 2021 and a detection subunit 2022 .

[0079] The logic control subunit 2021 is used to determine the hard disk 204 in place according to the in-place status information of each hard disk 204 on the backplane 20; the detection subunit 2022 is used to perform status detection on the hard disk 204 in place according to multiple decoding signals to obtain the detection result.

[0080] The logic control subunit 2021 may be a complex programmable logic device (CPLD), which is used to control signal transmission and processing between components on the backplane 20 .

[0081] The working principle of the detection device described in the embodiment of the present application is: Figure 2When the detection device shown detects the status of each hard disk 204 on the backplane 20, the signal unit 102 on the mainboard 10 can send multiple detection signals to the encoding circuit 101. After receiving the multiple detection signals, the encoding circuit 101 can integrate the multiple detection signals to obtain a target detection signal, and then send the target detection signal to the decoding circuit 201. After receiving the target detection signal, the decoding circuit 201 can decode or restore the integrated target detection signal to obtain multiple decoding signals, and send the multiple decoding signals to the logic control subunit 2021. After receiving the multiple decoding signals, the logic control subunit 2021 can first detect the in-place status of each hard disk 204 according to the in-place status information, and when it is determined that there is a hard disk 204 in place, generate a detection instruction according to the multiple detection signals, and send the detection instruction to each hard disk 204 to instruct each hard disk 204 to perform a corresponding operation according to the operation indicated by the detection instruction, and send the detection instruction to the detection subunit 202. 2, to indicate that the detection subunit 2022 reads the status data of the hard disk 204 from each hard disk 204 after receiving the detection instruction, and parses the status data to determine what working state each hard disk 204 is in, and further compares it with the working state corresponding to the operation indicated by the detection instruction. For example, if the detection instruction instructs the hard disk 204 to start or stop working, the corresponding working state should be a starting or stopping working state. At this time, the working state indicated by the detection instruction can be compared with the working state represented by the status data. If they are consistent, it is considered that the hard disk 204 is in a normal working state. If they are inconsistent, it is considered that the hard disk 204 is in an abnormal working state. It should be noted that when the detection subunit 2022 detects that the hard disk 204 is in an abnormal working state, the detection subunit 2022 can generate an abnormal file, and return the abnormal file to the logic control subunit 2021 and return it step by step to the baseboard management controller in the signal unit 102, and display the abnormal state information under the baseboard management controller.

[0082] The detection device provided in the embodiment of the present application can detect the working status of each hard disk by setting up a detection subunit. Compared with the traditional device that can only detect the presence of the hard disk, the above device can perform a comprehensive detection of the hard disk. In addition, assigning the detection of the hard disk to the detection subunit can reduce the working pressure of the control unit and further improve the test efficiency.

[0083] In one embodiment, a detection device 1 is also provided, such as Figure 3 As shown, based on the detection device 1 described in the above embodiment, the control unit 202 in the detection device 1 further includes: a verification subunit 2023.

[0084] The verification subunit 2023 is used to verify multiple decoded signals to obtain multiple verified signals. Correspondingly, the logic control subunit 2021 is specifically used to determine the hard disk in place according to the in-place status information of each hard disk on the backplane when receiving the multiple verified signals. The detection subunit 2022 is specifically used to perform status detection on the hard disk in place according to the multiple verified signals to obtain the detection result.

[0085] The above check subunit 2023 can be implemented by using clock recovery technology (Clock and Data Recovery, CDR for short).

[0086] The working principle of the detection device described in the embodiment of the present application is: Figure 3 When the detection device shown detects the status of each hard disk 204 on the backplane 20, the signal unit 102 on the mainboard 10 can send multiple detection signals to the encoding circuit 101. After receiving the multiple detection signals, the encoding circuit 101 can integrate the multiple detection signals to obtain a target detection signal, and then send the target detection signal to the decoding circuit 201. After receiving the target detection signal, the decoding circuit 201 can decode or restore the integrated target detection signal to obtain multiple decoded signals, and send the multiple decoded signals to the verification subunit 2023. After receiving the multiple decoded signals, the verification subunit 2023 can use the clock recovery technology to perform clock verification on the multiple decoded signals, and then send the verified multiple decoded signals to the logic control subunit 2021. After receiving the verified multiple decoded signals, the logic control subunit 2021 can detect the status of each hard disk 204 according to the verified multiple decoded signals.

[0087] The detection device provided in the embodiment of the present application adds a check subunit to check the signal restored by the decoding circuit, which can prevent the problem of failure to detect or inaccurate detection due to decoding errors of the decoding circuit or omissions in data transmission.

[0088] In one embodiment, a detection device 1 is also provided, such as Figure 4 As shown, in Figure 1 On the basis of the detection device 1 described in the embodiment, the detection device 1 further includes: an integrated circuit 103 .

[0089] The integration circuit 103 is used to integrate some detection signals among the multiple detection signals to obtain an integration signal. Correspondingly, the encoding circuit 101 is specifically used to integrate the integration signal with the detection signals other than the partial detection signals to obtain a target detection signal.

[0090] The integrated circuit 103 may be a signal converter. The partial detection signals are in-position detection signals, which are used to control the hard disk 204 to perform a lighting operation. The detection signals other than the partial detection signals are working state detection signals, which are used to control the hard disk 204 to perform a corresponding work process. Optionally, the in-position detection signal may be an SGPIO signal, and the working state detection signal may be an I2C signal. The SGPIO signal includes four groups of signals, namely, a SClock signal, an SLoad signal, an SDataOut signal, and an SDataIn signal. Among them, the SClock signal is a clock signal, such as a 100k clock signal, the SLoad signal indicates the end signal of the current bit stream, or starts a new bit stream at the next clock, which is used to indicate when the bit stream ends and restarts; the SDataOu signal indicates the bit stream of serial data output, which carries the output bit associated with the disk drive on the backplane 20, and is used to control the LED and other indicator lights (such as activity, positioning and error indicators); the SDataIn signal indicates the serial data table input bit stream, which carries the input bit associated with the disk drive on the backplane 20, and is used to report information such as drive presence detection (such as SATA). It should be noted that the SDataIn signal is determined by the needs of the server, and not all devices support the SDataIn signal. The principle that the signal unit 102 sends the SGPIO signal to the logic control subunit 2021, and the logic control subunit 2021 parses the SGPIO signal, and then controls the hard disk startup according to the SGPIO signal is: the logic control subunit 2021 uses the falling edge of the SClock signal to lock the SLoad signal and the SDataOut signal, and the signal unit 102 uses the falling edge of the SClock signal to lock the SDataIn signal. When the bus using the SGPIO signal intentionally does not exchange the bit stream, the signal unit 102 sets the SClock signal to 0, so that the logic control subunit 2021 knows that the initiator still exists and has not been deleted, and the clock cycle that sets the SLoad signal to 1 is the last clock cycle of the bit stream.

[0091] The working principle of the detection device described in the embodiment of the present application is: Figure 4When the detection device shown detects the status of each hard disk 204 on the backplane 20, the signal unit 102 on the mainboard 10 can send a partial detection signal to the integration circuit 103, and send a detection signal other than the partial detection signal to the encoding circuit 101. After receiving the partial detection signal, the integration circuit 103 can integrate the partial detection signal to obtain an integrated signal, and then send the integrated signal to the encoding circuit 101. After receiving the detection signal other than the partial detection signal and the integration signal, the encoding circuit 101 can integrate the integration signal and the detection signal other than the partial detection signal again to obtain a target detection signal.

[0092] The detection device provided by the embodiment of the present application can effectively save the number of pins of the encoding circuit by integrating the signal through the integration circuit. In particular, when it is necessary to perform status detection on multiple hard disks, since the number of pins of the encoding circuit is limited, the method of first integrating the signal by the integration circuit can significantly reduce the number of required pins. The above detection method can improve the scalability and flexibility of the system while reducing the complexity of the system. In addition, after the signal is integrated by the integration circuit, the integrated signal is sent to the encoding circuit, which can more efficiently perform data transmission and status detection.

[0093] In one embodiment, a detection device 1 is also provided, such as Figure 5 As shown, in Figure 1 On the basis of the detection device 1 described in the embodiment, the detection device 1 further includes: a signal interface 104 .

[0094] The encoding circuit 101 sends the target detection signal to the decoding circuit 201 through the signal interface 104 .

[0095] The working principle of the detection device described in the embodiment of the present application is: Figure 5 When the detection device 1 shown detects the status of each hard disk 204 on the backplane 20, the signal unit 102 on the mainboard 10 can send multiple detection signals to the encoding circuit 101. After receiving the multiple detection signals, the encoding circuit 101 can integrate the multiple detection signals to obtain a target detection signal, and then send the target detection signal to the decoding circuit 201 through the signal interface 104. After receiving the target detection signal, the decoding circuit 201 can decode or restore the integrated target detection signal to obtain multiple decoding signals, and send the multiple decoding signals to the control unit 202. After receiving the multiple decoding signals, the control unit 202 can first detect the in-place status of each hard disk 204 according to the in-place detection signal, and when it is determined that there is a hard disk 204 in place, the control unit 202 then detects the working status of the hard disk 204 in place according to the working status detection signal to obtain a detection result.

[0096] The detection device provided in the embodiment of the present application transmits the target detection signal to the decoding circuit through a very small number of signal interfaces, thereby solving the problem of complex circuit structure caused by the traditional use of multiple signal transmission lines. When the number of hard disks is relatively large, the detection device can greatly reduce the number of signal lines, that is, greatly simplify the signal transmission lines of the circuit, thereby reducing the detection cost of the detection device to a certain extent.

[0097] In one embodiment, a detection device 1 is further provided. Based on the detection device 1 described in the above embodiment, the detection device 1 further includes an indicator light connected to each hard disk 204 , and each indicator light is connected to the detection subunit 2022 .

[0098] The detection subunit 2022 is also used to light up each indicator light according to the status data of each hard disk 204 and the detection instruction.

[0099] Optionally, the indicator light can be a light emitting diode; optionally, the color of the indicator light can represent different states of the hard disk 204, for example, when the color of the indicator light is green, it indicates that the hard disk 204 is in a normal state; when the color of the indicator light is red, it indicates that the hard disk 204 is in an abnormal state.

[0100] The working principle of the detection device described in the embodiment of the present application is as follows: when the detection device 1 is used to detect the status of each hard disk 204 on the backplane 20, the logic control subunit 2021 can, after receiving multiple decoding signals, first detect the in-place status of each hard disk 204 according to the in-place status detection signal, and when it is determined that there is a hard disk 204 in place, generate a detection instruction according to the multiple detection signals, and send the detection instruction to each hard disk 204 to instruct each hard disk 204 to perform a corresponding operation according to the operation indicated by the detection instruction, and send the detection instruction to the detection subunit 2022 to instruct the detection subunit 2022 to read the status data of the hard disk 204 from each hard disk 204 after receiving the detection instruction, and parse the status data to determine what working state each hard disk 204 is in. state, and further compare it with the working state corresponding to the operation indicated by the detection instruction. For example, if the detection instruction instructs the hard disk 204 to start or stop working, the corresponding working state should be the started or stopped working state. At this time, the working state indicated by the detection instruction can be compared with the working state represented by the status data. If they are consistent, it is considered that the hard disk 204 is in a normal working state. At this time, the detection subunit 2022 can light up the indicator light connected to the hard disk 204 in a normal state, for example, the detection subunit 2022 controls the indicator light to turn on green; if they are inconsistent, it is considered that the hard disk 204 is in an abnormal working state. At this time, the detection subunit 2022 can light up the indicator light connected to the hard disk 204 in an abnormal state, for example, the detection subunit 2022 controls the indicator light to turn on red.

[0101] The detection device provided in the embodiment of the present application can reflect the different states of the hard disk by connecting the indicator light to the hard disk. Therefore, there is no need to enter the hard disk management interface. The working status of the hard disk can be quickly understood by simply observing the status changes of the indicator light, which is beneficial for users to troubleshoot and monitor the operating status of each hard disk on the backplane.

[0103] Among them, the integration circuit 103 is used to integrate some of the detection signals among the multiple detection signals output by the signal unit 102 on the mainboard to obtain an integrated signal. The encoding circuit 101 is used to integrate the integrated signal and the detection signals other than the partial detection signals to obtain a target detection signal.

The logic control subunit 2021 is used to determine the hard disk 204 in place according to the in-place status information of each hard disk 204 on the backplane 20. The detection subunit 2022 is used to perform status detection on the hard disk 204 in place according to the multiple decoded signals to obtain a detection result.

[0105] The working principle of the detection device 2 described in the embodiment of the present application is: Figure 6When the detection device 2 shown detects the status of each hard disk 204 on the backplane 20, the signal unit 102 on the mainboard 10 can send a partial detection signal (control signal) to the integration circuit 103, and send a detection signal (SGPIO signal) other than the partial detection signal to the encoding circuit 101. After receiving the partial detection signal, the integration circuit 103 can integrate the partial detection signal to obtain an integration signal, and then send the integration signal to the encoding circuit 101. After receiving the detection signal other than the partial detection signal and the integration signal, the encoding circuit 101 can integrate the integration signal and the detection signal other than the partial detection signal again to obtain a target detection signal, and then send the target detection signal to the decoding circuit 201 through the signal interface 104 using a cable. After receiving the target detection signal, the decoding circuit 201 can decode or restore the integrated target detection signal to obtain multiple decoding signals (SGPIO signal and I2C signal), and send the multiple decoding signals to the check subunit 2023. After receiving multiple decoded signals, the check subunit 2023 can use clock recovery technology to perform clock check on the multiple decoded signals, and then send the multiple decoded signals after check to the logic control subunit 2021. After receiving multiple verified decoded signals, the logic control subunit 2021 can first detect the in-place status of each hard disk 204 according to the in-place status information, and when it is determined that there is a hard disk 204 in place, generate a detection instruction (ACT signal) according to multiple detection signals, and send the detection instruction to each hard disk 204 to instruct each hard disk 204 to perform a corresponding operation according to the operation indicated by the detection instruction, and send the detection instruction to the detection subunit 2022 to instruct the detection subunit 2022 to read the status data of the hard disk 204 from each hard disk 204 after receiving the detection instruction, and parse the status data to determine what working state each hard disk 204 is in, and then further perform the operation corresponding to the operation indicated by the detection instruction. The working status is compared, for example, if the detection instruction instructs the hard disk 204 to start or stop working, the corresponding working status should be the started or stopped working status. At this time, the working status indicated by the detection instruction can be compared with the working status represented by the status data. If they are consistent, it is considered that the hard disk 204 is in a normal working state. At this time, the detection subunit 2022 can light up the indicator light connected to the hard disk 204 in a normal state, for example, the detection subunit 2022 controls the indicator light to light up green; if they are inconsistent, it is considered that the hard disk 204 is in an abnormal working state. At this time, the detection subunit 2022 can light up the indicator light connected to the hard disk 204 in an abnormal state, for example, the detection subunit 2022 controls the indicator light to light up red.It should be noted that when the detection subunit 2022 detects that the hard disk 204 is in an abnormal working state, the detection subunit 2022 can generate an abnormal file, and return the abnormal file to the logic control subunit 2021 and return it step by step to the baseboard management controller in the signal unit 102, and display the abnormal status information under the baseboard management controller.

After receiving part of the SGPIO signal and the control signal, the I2C SW can integrate part of the SGPIO signal and the control signal to obtain an integrated signal, and then send the integrated signal to the Serializer. After the Serializer receives another part of the SGPIO signal and the integrated signal, it can integrate the integrated signal and another part of the SGPIO signal again to obtain a target detection signal, and then send the target detection signal to the Deserializer through the interface using the Cable cable. After receiving the target detection signal, the Deserializer can decode or restore the integrated target detection signal to obtain multiple decoded signals, such as SGPIO signals and I2C signals, and send the multiple decoded signals to the CDR module.
