[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The terms "including" and "having" in the specification of the present invention and the above-mentioned drawings, as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed.

[0044] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] Next, a hard disk status display control device provided by an embodiment of the present invention is described in detail. Figure 1 As shown, Figure 1 A structural diagram of a hard disk status display control device provided by an embodiment of the present invention; the hard disk status display control device is applied to a server, the server is connected to the hard disk, and the hard disk status display control device includes:

[0046] Processor 1, the first output pin is connected to the in-place indicator light 2, and the second output pin is respectively connected to the input end of the fault indicator light 3 and the signal conversion module 5, for outputting an in-place control signal to the in-place indicator light 2 based on the in-place status information of the hard disk, so as to control the in-place indicator light 2 to display whether the hard disk is in place; if only the fault status information of the hard disk is received, then the fault control signal is output to the fault indicator light 3 and the signal conversion module 5 based on the fault status information, so as to control the fault indicator light 3 to display whether the hard disk is faulty; if the positioning information of the hard disk and the fault status information of the hard disk are received or only the positioning information of the hard disk is received, then the positioning control signal is output to the fault indicator light 3 and the signal conversion module 5; wherein, the fault indicator light 3 has no response when receiving the positioning control signal;

[0047] The signal conversion module 5 has an output end connected to the positioning indicator light 4 and is used for not controlling the positioning indicator light 4 when a fault control signal is received; and controlling the positioning indicator light 4 to display the hard disk positioning when a positioning control signal is received.

[0048] It is not difficult to understand that as the number of hard disks that a server can support continues to increase, the signals that the server needs to monitor and manage will also increase. This poses a new challenge to the number of CPLD (Complex Programmable Logic Device) logic resource pins of the backplane. In a server, each hard disk connected to it requires a certain number of CPLD pins for status monitoring and management, which leads to a sharp increase in the demand for CPLD pins when the number of hard disks increases. In order to solve this problem, the present invention proposes an innovative backplane lighting solution design, which can effectively save the use of CPLD pins in a multi-port backplane scenario, improve resource utilization efficiency, and significantly improve the scalability and manageability of the server.

[0049] It can be understood that for any hard disk connected to the server, a status display device and a status display control device corresponding to the hard disk are set in the server. The processor 1 in the status display control device has a first output pin and a second output pin corresponding to the hard disk, and a signal conversion module 5 corresponding to the hard disk is set. The status monitoring of any hard disk and the corresponding display control are achieved by the method provided in this application. In order to realize the status monitoring of the hard disk, the status display device is provided with an in-position indicator light 2 (Active), a fault indicator light 3 (Error), and a positioning indicator light 4 (Locate) corresponding to the hard disk. The in-position indicator light 2 is mainly used to display the in-position status of the hard disk. The display status of the in-position indicator light 2 is different when the hard disk is in place and when the hard disk is not in place. For example, it can be designed to be always on since the hard disk is in place. The processor 1 determines whether the hard disk is in place according to the in-position status information of the hard disk, and outputs the corresponding in-position control signal to control the in-position indicator light 2. The in-position indicator light 2 is connected to the processor 1 through the first output pin. The processor 1 can only control the in-position indicator light 2 through the second output pin, and cannot use the second output pin and / or the signal conversion module 5 to control the in-position indicator light 2. The fault indicator light 3 is mainly used to display whether the hard disk is faulty or not. The display status of the fault indicator light 3 is different when the hard disk is faulty and when the hard disk is in normal use. Generally, the fault indicator light 3 will be displayed when the hard disk is faulty; the positioning indicator light 4 is mainly used to display when the hard disk needs to be located.

[0050] It should be noted that, if the hard disk is in place, the hard disk has not failed and there is no need to locate the hard disk, although the processor 1 will control the in-place indicator light 2 to display that the hard disk is in place, the fault indicator light 3 and the positioning indicator light 4 are both in an unused state. Therefore, the second output pin of the processor 1 essentially has a control process of three states, namely, the three states of no response of the fault indicator light 3 and the positioning indicator light 4, controlling the fault indicator light 3 to display, and controlling the positioning indicator light 4 to display. In the present invention, a signal conversion module 5 is set at the second output pin of the processor 1 to cooperate with the processor 1 to realize the switching of the three states. The output signal of the second output pin of the processor 1 includes a fault control signal, a positioning control signal, and an unused control signal that makes the fault indicator light 3 and the positioning indicator light 4 unresponsive. The three-state control circuit is used to realize that the CPLD can realize the switching of the on and off states of the fault indicator light 3 and the positioning indicator light 4 through three-state switching with only one IO pin, thereby saving the IO pin resources of the CPLD.

[0051] Specifically, the processor 1 can realize the three-state switching process by outputting three signals: a first level signal, a second level signal and a high-impedance state. The first level signal and the second level signal are opposite. Taking the fault indicator light 3 as being always on when the hard disk fails, the positioning indicator light 4 as being always on when the processor 1 receives the positioning information of the hard disk, and the in-place indicator light 2 as being always on when the hard disk is in place as an example, when the processor 1 determines that the hard disk is in place according to the received in-place status information of the hard disk, the first output pin of the processor 1 outputs the first level signal as the in-place control signal to control the in-place indicator light 2 to remain always on; when the processor 1 determines that the hard disk is not in place according to the received in-place status information of the hard disk, the first output pin of the processor 1 outputs the second level signal as the in-place control signal to control the in-place indicator light 2 to remain always off. When the processor 1 does not receive the fault status information or the positioning information, the second output pin of the processor 1 outputs a high-impedance signal, that is, the second output pin remains in a high-impedance state, and the fault indicator light 3 and the positioning indicator light 4 both remain normally off; when the processor 1 only receives the fault status information, the second output pin of the processor 1 outputs a first level signal as a fault control signal, at which time the fault indicator light 3 remains normally on under the action of the first level signal, and the signal conversion module 5 does not control the positioning indicator light 4 when receiving the first level signal, and the positioning indicator light 4 remains normally off; when the processor 1 only receives the positioning information, the second output pin of the processor 1 outputs a second level signal as a positioning control signal, at which time the fault indicator light 3 has no response under the action of the second level signal and remains normally off, and the signal conversion module 5 controls the positioning indicator light 4 to display when receiving the second level signal, and the positioning indicator light 4 remains normally on; when the processor 1 receives the fault status information and the positioning information at the same time, it responds to the positioning information first, and then responds to the fault status information after the positioning information response is completed. Therefore, the processor 1 outputs a first level signal, a second level signal and a high impedance state, utilizes a second output pin, and cooperates with the signal conversion module 5 to realize the control process of the two status lights, the fault indicator light 3 and the positioning indicator light 4. The lighting of the fault indicator light 3 and the positioning indicator light 4 can be realized through a single pin and a three-state control circuit on the backplane.

[0052] It is not difficult to understand that the specific type and implementation method of the server are not specifically limited in this application. There are also multiple options for the specific number and type of hard disks connected to it, which are not specifically limited in this application. The hard disk can be an NVME hard disk, a SAS / SATA hard disk, etc. The processor 1 in the server can specifically be a CPLD, or it can be implemented by the cooperation of CPLD and other modules such as CPU (Central Processing Unit). The specific type and implementation method of the processor 1 are not specifically limited in this application, and there are multiple ways to implement it. The specific circuit structure and implementation method of the signal conversion module 5 are not specifically limited in this application. The specific implementation method of the processor 1 obtaining the in-place status information, fault status information and positioning information of the hard disk is not specifically limited in this application. For different types of hard disks, the methods of obtaining relevant information may be different.

[0053] The present invention provides a lighting scheme design for saving CPLD pin resources. Only two IO pins are used to realize the control operation of CPLD on the lighting of Active, Error and Locate lights of a hard disk. In the scenario where the IO pins of the CPLD are insufficient, the number of IO pins of the CPLD can be expanded in disguise, and the lighting circuit can be used to switch the CPLD on the backplane, replacing the expensive CPLD with a cheaper CPLD with slightly fewer pins. On the other hand, the IO pins of the CPLD can be effectively released to realize more logic function judgments.

[0054] As a specific embodiment, see Figure 2 As shown, Figure 2A structural diagram of a hard disk status display device provided by an embodiment of the present invention; there are n independent hard disks in the Raid, so the server is provided with n hard disk status display devices corresponding to each of SSD1 to SSDn, and the processors 1 of the n hard disk status display devices are all implemented by the CPLD and CPU of the server itself. Processor 1 is implemented by the CPLD and CPU, and the CPLD and the CPU are connected through a communication bus, and the CPU transmits VPP (Virtual Pin Port) information for PCI SSD Enclosure management through the communication bus; the CPLD is connected to the Raid composed of multiple hard disks through SGPIO (Serial General Purpose Input / Output). According to the function of the three-state control circuit, the lighting operation of the Error and Locate lights of the hard disk is realized. A logical control implementation method for lighting the hard disk can be summarized as follows: In the first case, when the hard disk is not in place, the CPLD controls the first output pin to output a high level and controls the second output pin to output a high impedance state. At this time, the in-place indicator light 2, the fault indicator light 3, and the positioning indicator light 4 are all kept off. The second case is when the hard disk is in place and there is no read or write operation, the CPLD controls the first output pin to maintain the output low level, and controls the second output pin to output a high impedance state. At this time, the in-place indicator light 2 is always on, and the fault indicator light 3 and the positioning indicator light 4 are always off. The third case is when the hard disk is performing a read or write operation, the CPLD controls the first output pin to output a low level at a frequency of 4Hz, and controls the second output pin to output a high impedance state. At this time, the in-place indicator light 2 flashes at a frequency of 4Hz, and the fault indicator light 3 and the positioning indicator light 4 are always off. The fourth case is when the CPLD parses the hard disk fault information in the VPP / SGPIO signal, it controls the second output pin to output a high level signal, at this time the fault indicator light 3 is always on, and the positioning indicator light 4 is always off. The fifth case is that after the CPLD parses the hard disk location information in the VPP / SGPIO signal, it controls the second output pin to output a low level signal. At this time, the fault indicator 3 is always off and the location indicator 4 is always on. The sixth case is that when the hard disk is being rebuilt, the CPLD controls the second output pin to output high and low levels in sequence at a frequency of 1Hz. At this time, the fault indicator 3 and the location indicator 4 flash at a frequency of 1Hz. The lighting logic of the above CPLD can be summarized as shown in Table 1.

[0055] Table 1

[0056]

[0057] In some embodiments, the processor 1 is further used to output a repair control signal to the fault indicator light 3 and the signal conversion module 5 when the hard disk performs a repair operation, so as to control the fault indicator light 3 to perform a repair display;

[0058] The signal conversion module 5 is also used to control the positioning indicator light 4 to perform repair display when receiving the repair control signal.

[0059] It is not difficult to understand that, on the basis of performing fault display and positioning display, the processor 1 can also realize the display of other special states when the hard disk is in place by outputting other signals different from the fault control signal and the positioning control signal. For example, when the hard disk performs a repair (Rebuild) operation, the repair control signal can be output to control the fault indicator light 3 and the positioning indicator light 4 to display. The fault display of the fault indicator light 3 and the positioning display of the positioning indicator light 4 are generally displayed in a constant light manner. Therefore, the repair control signal can be specifically realized by outputting the first level signal and the second level signal in sequence at a specific frequency. At this time, the fault indicator light 3 and the positioning indicator light 4 will flash at the specific frequency, thereby realizing a repair display different from the constant light. For example, the processor 1 can output high and low levels in sequence at a frequency of 1Hz, and at this time, the fault indicator light 3 and the positioning indicator light 4 flash at a frequency of 1Hz. The present application does not make any special restrictions on the implementation of the repair control signal and the repair display, and is not limited to the implementation proposed in this embodiment, nor is it limited to displaying the Rebuild operation of the hard disk. It can also display other functional operations or states when the hard disk is in place, and the present application does not make any special restrictions on this.

[0060] Specifically, based on the fault display and positioning display, the output signal of the second output pin can distinguish between multiple output signals through frequency and other methods, thereby realizing the differentiated display of multiple functional operations and status when the hard disk is in place, which is conducive to achieving more comprehensive monitoring of the hard disk.

[0061] In some embodiments, the processor 1 is also used to adjust the in-place control signal output to the in-place indicator light 2 to a read-write control signal when the hard disk in-place status information indicates that the hard disk is in place and it is recognized that the hard disk is performing read and write operations, so as to control the in-place indicator light 2 to perform read and write display.

[0062] It is understandable that the in-place indicator light 2 can also further detect the hard disk by adjusting the output signal of the first output pin when only displaying whether the hard disk is in place. For example, when the hard disk is in place and read and write operations are performed, the in-place control signal output by the first output pin can be adjusted to a read and write control signal, but the read and write control signal needs to include a display operation that represents the hard disk in place. Generally, the in-place indicator light 2 will represent the hard disk in place by being in a constant light state, and the hard disk is not in place by being in a constant off state. On this basis, a first level signal of a specific frequency can be set. When the processor 1 outputs a continuous first level signal, the in-place indicator light 2 remains in a constant light state to represent the hard disk in place. When the processor 1 outputs the first level signal at a specific frequency, the in-place indicator light 2 will also flash at the specific frequency. At this time, not only the in-place indicator light 2 indicates that the hard disk is in place, but also the flashing indicates that the hard disk is undergoing a read and write operation. The present application does not make any special limitation on the implementation method of the read and write control signals. It is not limited to the implementation method proposed in this embodiment, nor is it limited to displaying the read and write operations of the hard disk. It can also further distinguish between the reading and writing of the hard disk, etc. The present application does not make any special limitation on this.

[0063] Specifically, on the basis of displaying the hard disk in place, the output signal of the first output pin can distinguish between multiple output signals through frequency and other means, thereby taking into account the simultaneous display of the hard disk in place and the normal operation when the hard disk is in place, which is conducive to achieving more comprehensive monitoring of the hard disk.

[0064] In some embodiments, a first end of the in-position indicator light 2 is connected to a first output pin of the processor 1, and a second end is connected to a first power supply; the hard disk status display control device further includes:

[0065] A first current limiting module R1, a first end of which is connected to the first power supply, and a second end of which is connected to the second end of the presence indicator light 2;

[0066] and / or,

[0067] The first pull-up module R11 has a first end connected to the first power supply, and a second end connected to the first end of the presence indicator light 2 and the first output pin of the processor 1 respectively.

[0068] It is not difficult to understand that the second end of the presence indicator light 2 can be fixedly connected to the first power supply, and the processor 1 controls the light by outputting a low-level signal. At this time, in order to avoid the impact of excessive voltage or current on the presence indicator light 2 when the power supply loop is formed, a first current limiting module R1 connected in series with the presence indicator light 2 can be added. The first current limiting module R1 can limit the current flowing through the presence indicator light 2, thereby protecting the circuit. At the same time, considering that the processor 1 needs to continuously output a high-level signal to control the presence indicator light 2 to be constantly off, in order to ensure the stability of the high-level signal output by the processor 1, a first pull-up module R11 connected to the first output pin can also be added. When the processor 1 outputs a high level, the first pull-up module R11 can be used to ensure the stability of the voltage output to the first end of the presence indicator light 2, thereby ensuring that the presence indicator light 2 is constantly off. The present application does not make any special restrictions on the specific types and implementation methods of the first current limiting module R1 and the first pull-up module R11. Both can be implemented by resistors, and their resistance values ​​can be selected and set according to the actual application. Specifically, a 150Ω resistor can be used to implement the first current limiting module R1, and a 4.7kΩ resistor can be used to implement the first pull-up module R11. The present application does not make any special restrictions on the specific implementation method of the first power supply, and specifically, it can be implemented with a power supply voltage of 3.3V.

[0069] Specifically, a peripheral circuit connected to the presence indicator light 2 can be further provided to avoid damage to the presence indicator light 2 through the first current limiting module R1, thereby improving the safety and reliability of the entire circuit; at the same time, the first pull-up module R11 is used to ensure that the processor 1 accurately controls the presence indicator light 2 through the first output pin, thereby avoiding abnormal display of the indicator light due to unstable output signals.

[0070] In some embodiments, the first end of the fault indicator light 3 is connected to the input end of the signal conversion module 5 and the second output pin of the processor 1 respectively, and the second end is grounded; the hard disk status display control device also includes:

[0071] A second current limiting module R2, a first end of which is connected to a first end of the fault indicator light 3, and a second end of which is respectively connected to an input end of the signal conversion module 5 and a second output pin of the processor 1;

[0072] and / or,

[0073] The second pull-up module R12 has a first end connected to the second power supply, and a second end connected to the input end of the signal conversion module 5, the second output pin of the processor 1 and the first end of the fault indicator light 3 respectively.

[0074] It is understandable that the second end of the fault indicator light 3 can be kept fixedly grounded, and at this time the processor 1 can use the high-level signal as a fault control signal, and the second output pin can control the fault indicator light 3 to light up when the second output pin outputs a high-level signal. At this time, in order to avoid the impact of excessive voltage or excessive current on the fault indicator light 3 when the output signal of the second output pin forms a power supply loop, a second current limiting module R2 connected in series with the fault indicator light 3 can be added, and the second current limiting module R2 can limit the current flowing through the fault indicator light 3, thereby protecting the circuit. Considering that the processor 1 needs to continuously output a high-level signal to control the fault indicator light 3 to light up, in order to ensure the stability of the high-level signal output by the processor 1, a second pull-up module R12 connected to the second output pin can also be added. When the processor 1 outputs a high level, the second pull-up module R12 can be used to ensure the stability of the output voltage, thereby ensuring that the fault indicator light 3 lights up. The present application does not make any special restrictions on the specific types and implementation methods of the second current limiting module R2 and the second pull-up module R12. Both can be implemented in the form of resistors, and the resistance values ​​can be selected and set according to the actual application. Specifically, a 150Ω resistor can be used to implement the second current limiting module R2, and a 50kΩ resistor can be used to implement the second pull-up module R12. The present application does not make any special restrictions on the specific implementation method of the second power supply, and specifically, it can be implemented with a power supply voltage of 12V.

[0075] Specifically, a peripheral circuit connected to the fault indicator light 3 can be further provided to avoid damage to the fault indicator light 3 through the second current limiting module R2, thereby improving the safety and reliability of the entire circuit; at the same time, the second pull-up module R12 is used to ensure that the processor 1 accurately controls the fault indicator light 3 and the positioning indicator light 4 through the second output pin, thereby avoiding abnormal display of the indicator light due to unstable output signals.

[0076] In some embodiments, the first end of the fault indicator light 3 is connected to the input end of the signal conversion module 5 and the second output pin of the processor 1 respectively, and the second end is grounded; the first end of the positioning indicator light 4 is connected to the output end of the signal conversion module 5, and the second end is grounded;

[0077] The signal conversion module 5 includes:

[0078] A third current limiting module R3, a first end of which is connected to the second output pin of the processor 1;

[0079] A voltage dividing module R13, a first end of which is connected to a second power supply;

[0080] A first controllable switch Q1, whose control end is connected to the second end of the third current limiting module R3 and whose first end is grounded, is used to be turned on when its control end receives a fault control signal and turned off when its control end receives a positioning control signal;

[0081] A fourth current limiting module R4, a first end of which is connected to the second power supply;

[0082] The second controllable switch Q2, the control end is respectively connected to the second end of the first controllable switch Q1 and the second end of the voltage divider module R13, the first end is connected to the second end of the fourth current limiting module R4, and the second end is connected to the first end of the positioning indicator 4; it is used to be turned off when the first controllable switch Q1 is turned on, and turned on when the first controllable switch Q1 is turned off, so as to use the second power supply to control the positioning indicator 4 to display the positioning of the hard disk.

[0083] It is not difficult to understand that it is necessary to build a signal conversion module 5 as a three-state control circuit according to the specific conditions of the fault indicator light 3 and the positioning indicator light 4. This embodiment takes the second ends of the fault indicator light 3 and the positioning indicator light 4 as an example of being fixed and grounded, and provides a specific implementation method of the signal conversion module 5. At this time, the processor 1 uses a high-level signal as a fault control signal and a low-level signal as a positioning control signal. When the second output pin outputs a high-level signal, the fault indicator light 3 will light up under the action of the high-level signal. At this time, the signal conversion module 5 needs to convert the high-level signal into a low-level signal to make the positioning indicator light 4 unresponsive; when the second output pin outputs a low-level signal, the fault indicator light 3 will go out under the action of the low-level signal. At this time, the signal conversion module 5 needs to convert the low-level signal into a high-level signal to control the positioning indicator light 4 to light up.

[0084] It can be understood that the present embodiment uses the conduction or shutoff of the controllable switch to realize signal conversion. When the second output pin outputs a high-level signal, the high-level signal controls the first controllable switch Q1 to conduct, and the turned-on first controllable switch Q1 pulls down the control end of the second controllable switch Q2, so that the second controllable switch Q2 is turned off, so that the signal cannot be output to control the positioning indicator light 4, and the positioning indicator light 4 remains off; when the second output pin outputs a low-level signal, the low-level signal controls the first controllable switch Q1 to turn off, and at this time, the second controllable switch Q2 will be turned on under the action of the second power supply, and the turned-on second controllable switch Q2 can output the second power supply to the positioning indicator light 4, thereby controlling the positioning indicator light 4 to light up. The present application does not make any special restrictions on the specific types and implementation methods of the first controllable switch Q1 and the second controllable switch Q2, and can be implemented by a triode or the like.

[0085] On this basis, in order to avoid the impact of the output signal of the second output pin on the control end of the first controllable switch Q1, a third current limiting module R3 connected to the control end of the first controllable switch Q1 can be set to protect the safety of the first controllable switch Q1. At this time, the second pull-up module R12 can also further play the role of a bias resistor to ensure the accurate operation of the first controllable switch Q1. In order to avoid the impact of the second power supply on the second controllable switch Q2, a voltage divider module R13 and a fourth current limiting module R4 can also be added. The voltage divider module R13 can further play the role of a bias resistor to ensure the accurate operation of the second controllable switch Q2; the fourth current limiting module R4 can also limit the current output to the positioning indicator light 4 in the process of controlling the positioning indicator light 4, thereby further protecting the circuit. The present application does not make any special restrictions on the specific types and implementation methods of the third current limiting module R3, the voltage divider module R13 and the fourth current limiting module R4. They can all be implemented in the form of resistors, and their resistance values ​​can be selected and set according to the actual application. Specifically, a 1kΩ resistor can be used to implement the third current limiting module R3 and the fourth current limiting module R4, and a 4.7kΩ resistor can be used to implement the voltage divider module R13.

[0086] On this basis, the following describes the specific implementation method of how processor 1 determines the hard disk status. Processor 1 can detect the REDAY signal of the hard disk in real time. The REDAY signal is a signal that indicates that the hard disk has normal power supply and communication functions. When CPLD detects that the REY (REDAY) signal transmitted from the hard disk is low, CPLD controls the first output pin corresponding to the hard disk to output a low level, and the in-position indicator light 2 is always on; at the same time, the second output pin is controlled to output a high impedance state, and the first controllable switch Q1 is turned on, the second controllable switch Q2 is not turned on, and the fault indicator light 3 and the positioning indicator light 4 are both always off, realizing the Active state lighting operation of the hard disk.

[0087] When it is necessary to locate and light up a hard disk, the current behavior is an NVME hard disk. At this time, the user will turn on the location option of the hard disk in the CPU BIOS and send a positioning instruction through the BIOS. After receiving the positioning instruction, the CPU will use VPP SMBUS sends a string of 8-bit data streams to CPLD, and the data stream includes the specific location of the hard disk that the user needs to locate. After the CPLD parses the location lighting information in the data stream, the CPLD controls the second output pin corresponding to the hard disk that needs to be located to output a low level. At this time, the first controllable switch Q1 is not turned on, the second controllable switch Q2 is turned on, the positioning indicator light 4 is always on, and the fault indicator light 3 is always off, thereby realizing the location light operation of the NVME hard disk; when the current behavior is a SAS / SATA hard disk, the user will turn on the location light option of the SAS / SATA disk in the Raid card option under BIOS. At this time, the Raid card will send a string of data streams to the CPLD through the SGPIO signal. After the CPLD parses the location lighting information in the data stream, the CPLD will control the corresponding second output pin to output a low level. At this time, the first controllable switch Q1 is not turned on, the second controllable switch Q2 is turned on, the positioning indicator light 4 is always on, and the fault indicator light 3 is always off, thereby realizing the location light operation of the SAS / SATA hard disk. After the user determines the specific location of the target hard disk according to the positioning indicator light 4, a positioning completion instruction will be further issued to inform the CPLD that the positioning has been completed. At this time, the second output pin corresponding to the processor 1 can stop outputting a low-level signal and stop controlling the positioning indicator light 4 to light up.

[0088] When you need to turn on the Error light of a hard disk, if the current line is an NVME hard disk, the CPU can directly identify the hard disk fault through the PCIE signal. When the CPU recognizes that an error has occurred in the hard disk being read through the PCIE signal band, the CPU will SMBUS sends a series of data streams to CPLD. After CPLD parses the Error light information in the data stream, CPLD controls the second output pin corresponding to the faulty hard disk to output a high level. At this time, the first controllable switch Q1 is turned on, and the second controllable switch Q2 is not turned on. At this time, the fault indicator light 3 is always on, and the positioning indicator light 4 is always off, realizing the operation of turning on the Error light of the NVME hard disk; when the downstream behavior is a SAS / SATA hard disk, the Raid card can identify the fault of the hard disk through the SAS signal. When the Raid card identifies an error in reading the hard disk through the SAS signal band, the Raid card will send a series of data streams to CPLD through the SGPIO signal. After CPLD parses the Error light information in the data stream, CPLD controls the second output pin to output a high level. At this time, the first controllable switch Q1 is turned on, and the second controllable switch Q2 is not turned on. At this time, the fault indicator light 3 is always on, and the positioning indicator light 4 is always off, realizing the operation of turning on the Error light of the SAS / SATA hard disk.

[0089] The backplane lighting scheme implemented by the present invention designs the fault indicator light 3 and the positioning indicator light 4 in a three-state control circuit, and the CPLD can realize the lighting function of a hard disk through only two IO pins. For each hard disk, the circuit can save the function of an IO pin of the CPLD. It can effectively reduce the waste of IO pin resources of the CPLD by the lighting circuit to achieve more CPLD logic function control; for some backplanes with sufficient IO pins of the CPLD, the lighting scheme of the present invention can replace the original CPLD with large logic resources and many pins with a CPLD with small logic resources and fewer pins, effectively improving the utilization rate of the IO pins of the CPLD and saving the production cost of the product.
