[0025] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence.

[0027] With the rapid development of cloud computing, artificial intelligence, and edge computing, the scale of data centers is growing exponentially, placing higher demands on electronic equipment architectures, such as server architectures, for computing density, resource sharing capabilities, and storage security and redundancy. Servers with multiple control nodes have become the mainstream architecture in data centers due to their high-density deployment and resource sharing.

[0028] Taking the server as an example, in the relevant technology, when controlling the lighting of the hard disk, the lighting control system in the server usually only supports a single controller (also called a control node) to exclusively control the specified single-port hard disk. For example, hard disk 0 is only controlled by the lighting of controller A, and hard disk 1 is only controlled by the lighting of controller B.

[0029] For example, see Figure 1 , Figure 1This is a schematic diagram of the structure of a lighting control system in the related art provided by this application, which includes a processing module 11, at least two lighting analysis modules 12, a lighting module 13, a presence detection module 14, and a timer monitoring module 15. Among them, the processing module 11 is connected to the lighting module 13, the presence detection module 14, and the timer monitoring module 15 respectively, the lighting module 13 is connected to the at least two lighting analysis modules 12, the at least two lighting analysis modules 12 are respectively connected to the corresponding controller 01, the presence detection module 14 is connected to each controller, and the timer monitoring module 15 is connected to each controller 01.

[0030] In related art, since lighting control systems typically only support exclusive control of a specific hard drive by a single controller, a specific control method in the lighting control system can be as follows: the processing module 11 obtains the presence information of a controller 01 through the presence detection module 14, and determines whether the controller 01 is in place based on the presence information. The processing module 11 also obtains the timer signal of the controller 01 through the timer monitoring module 15, and determines whether the controller 01 is in normal operation based on the timer signal. If it is in normal operation, the lighting information sent by the controller 01 is used by the lighting module to control the lighting of the corresponding single-port hard drive.

[0031] In recent years, dual-port hard drives have become popular to improve hard drive utilization and flexibility. However, when a dual-port hard drive is used by two controllers, if the two controllers issue conflicting lighting control commands—for example, if controller A issues a command to turn on the light while controller B issues a command to turn off the light—the lighting control system becomes unclear about which command to execute, leading to errors in the dual-port hard drive's lighting control. Therefore, a system and method for controlling the lighting of a dual-port hard drive using multiple controllers is urgently needed.

[0032] Therefore, in response to the above technical problems in the related art, it was found during the research process that when at least two controllers perform lighting control on the same dual-port hard disk, by setting different lighting modes, the lighting control system can clearly determine which controller should execute the lighting instruction sent by the lighting control system according to the control strategy under different lighting modes, thereby reducing the problem of inaccurate lighting control of the dual-port hard disk by the lighting control system caused by conflicting instructions issued by at least two controllers. Specifically, the present application provides a lighting control system, including an information processing module and a lighting arbitration module, the information processing module obtains the identification information of the target dual-port hard disk to be controlled sent by at least two controllers, and obtains the lighting mode control information input by the user. The lighting arbitration module determines the target lighting mode used to control the lighting of the target dual-port hard disk based on the identification information and the lighting mode control information, wherein the target lighting mode is a master-slave mode or an active-active mode.

[0033] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] See Figure 2 , Figure 2 This is a schematic diagram of the architecture of an electronic device with multiple control nodes provided in an embodiment of the present application, which includes at least two controllers 01, multiple connectors 02, a lighting control system 03 and multiple dual-port hard drives 04.

[0035] Controller 01 can also be called a control node or a server node. Figure 2 As shown, each controller 01 may further include multiple sub-controllers 011 . The sub-controllers 011 may be, for example, single-channel or dual-channel central processing units (CPUs) or baseboard management controllers (BMCs).

[0036] For any controller 01, the multiple sub-controllers 011 it includes are connected to the connector 02 in the backplane of the server through cables through the connector 02 in the controller 01. The sub-controller 011 can be connected to the connector 02 in the controller 01 through a virtual pin interface (Virtual Pin Port, VPP) or an integrated circuit bus (Inter-Integrated Circuit, I2C). The connector 02 in the backplane is connected to the lighting control system 03 through a cable. The lighting control system 03 is connected to another connector 02 in the backplane through a cable. The connector 02 is connected to the connector 02 in the dual-port hard disk backplane through a cable. The connector 02 in the dual-port hard disk backplane is connected to multiple dual-port hard disks 04. Multiple dual-port hard disk slots are provided in the dual-port hard disk backplane. Each slot can hot-swap dual-port hard disks. LED lights are set near the corresponding slots to display the status of the corresponding dual-port hard disks.

[0037] The server may further include a voltage regulator 05 (Voltage Regulator, VR), which is connected to the connector 02 in the dual-port hard disk backplane and the plurality of dual-port hard disks 04 and is used to control power on or off of each dual-port hard disk 04 .

[0038] The server may also include an I2C switch conversion module 06, which is connected to the connector 02 in the hard disk backplane and multiple dual-port hard disks 04, and is used to obtain hard disk self-monitoring, analysis and reporting technology (SMART) information of each dual-port hard disk 04.

[0039] The connector 02 may be a sideband connector, etc., the lighting control system 03 may be a complex programmable logic device (CPLD) or a microcontroller unit (MCU), etc., and the dual-port hard disk may be a dual-port non-volatile memory express (NVMe) hard disk drive (HDD).

[0040] It should be noted that the difference from the related technology is that the lighting control system 03 can support at least two controllers 01 to control the same dual-port hard disk. For example, hard disk 0 can be controlled by the lighting of controller A or the lighting of controller B, rather than the exclusive control in the related technology.

[0041] It is understandable that the above-mentioned server architecture only shows some components and does not limit the complete server architecture. This application also does not limit the number or type of components appearing in the server architecture, such as the controller 01, connector 02, lighting control system 03, dual-port hard disk 04, voltage regulator 05, and I2C switch conversion module 06.

[0042] See Figure 3A , Figure 3A This is a structural diagram of a lighting control system provided in an embodiment of the present application. In this embodiment, the lighting control system may be a CPLD, which includes an information processing module 31 and a lighting arbitration module 32 .

[0043] The connection relationship is: the information processing module 31 is connected to the lighting arbitration module 32.

[0044] The functions of each module are:

[0045] The information processing module 31 is configured to obtain identification information of a target dual-port hard disk to be controlled sent by at least two controllers 01 , and obtain lighting mode control information input by a user.

[0046] In this embodiment, the controller 01 may also be referred to as a control node, and the number of controllers 01 is described as two for example.

[0047] Optionally, the information processing module 31 may also be called an I2C slave information parsing module. The information processing module 31 obtains identification information of the target dual-port hard disk to be controlled sent by the two controllers 01. The identification information is used to determine which dual-port hard disk to be controlled.

[0048] The information processing module 31 also obtains the working mode information input by the administrator and configures the frame for parsing to obtain the lighting mode control information, and sends the above identification information and the lighting mode control information to the lighting arbitration module 32 .

[0049] The lighting arbitration module 32 is configured to determine a target lighting mode for controlling the lighting of the target dual-port hard disk according to the identification information and the lighting mode control information.

[0050] The target lighting mode is master-slave mode or active-active mode. In the master-slave mode, one of the two controllers 01 is pre-configured as the controller that obtains lighting control rights. In the active-active mode, no controller is pre-configured to obtain lighting control rights.

[0051] In the above embodiment of the present application, the lighting control system includes an information processing module and a lighting arbitration module, and the connection relationship thereof is: the information processing module is connected to the lighting arbitration module. Among them, the information processing module obtains the identification information of the target dual-port hard disk to be controlled sent by at least two controllers, and obtains the lighting mode control information input by the user. The lighting arbitration module determines the target lighting mode used to control the lighting of the target dual-port hard disk based on the identification information and the lighting mode control information, and the target lighting mode is a master-slave mode or an active-active mode. The lighting control system of the present application enables, when any dual-port hard disk is used by multiple controllers, the lighting arbitration module can determine the target lighting mode used to control the lighting of the target dual-port hard disk based on the identification information and the lighting mode control information sent by the information processing module. Since different lighting modes and control methods under different lighting modes are set, the occurrence of errors in the lighting control of any dual-port hard disk can be reduced, thereby achieving accurate control of the lighting of the dual-port hard disk.

[0052] See Figure 3B , Figure 3B This is a structural diagram of another lighting control system provided in an embodiment of the present application. In addition to the information processing module 31 and the lighting arbitration module 32, this embodiment also includes at least two lighting analysis modules 12 and a lighting module 13.

[0053] The connection relationship is: at least two lighting analysis modules 12 are connected to the corresponding controller 01, the lighting module 13 is connected to the lighting arbitration module 32 and at least two lighting analysis modules 12 respectively, and the controller 01 corresponding to at least two lighting analysis modules 12 is also connected to the information processing module 31.

[0054] The functions of each module are:

[0055] The controllers corresponding to the at least two lighting analysis modules 12 are configured to send identification information of the target dual-port hard disk to be controlled to the information processing module 31 .

[0056] In this embodiment, two lighting analysis modules 12 are used as an example for description, and there are also two controllers 01 connected to the two lighting analysis modules 12 .

[0057] The lighting arbitration module 32 is further configured to determine a target controller that obtains lighting control rights in the target lighting mode.

[0058] The present application may further include an in-position detection module 14 , which is connected to the lighting arbitration module 32 and each controller 01 .

[0059] The presence detection module 14 is used to obtain the presence information of each controller 01 and send it to the lighting arbitration module 32 .

[0060] Optionally, the presence detection module 14 obtains parameters of each controller 01 that can represent presence information.

[0061] Before determining the target lighting mode used to control the lighting of the target dual-port hard disk according to the identification information and the lighting mode control information, the lighting arbitration module 32 is further configured to:

[0062] The presence information of each controller 01 sent by the presence detection module 14 is obtained, and whether each controller 01 is in place is determined based on the presence information of each controller 01 .

[0063] Optionally, the lighting arbitration module 32 determines whether the corresponding controller 01 is in place based on the parameter indicating the presence of each controller 01 obtained from the presence detection module 14 and the parameter's identifier. For example, assuming that a pre-configured parameter indicating the presence of the controller 01 indicates that the corresponding controller 01 is in place when the identifier is "0," and indicates that the corresponding controller 01 is not in place when the identifier is "1."

[0064] If the lighting arbitration module 32 determines that only one controller 01 is in place based on the acquired information about the two controllers 01 , the lighting process of a single control node is entered.

[0065] If the lighting arbitration module 32 determines that both controllers 01 are in place based on the acquired information about the two controllers 01 , the dual-control node lighting process is entered.

[0066] If the lighting arbitration module 32 determines that the dual-control node lighting process has been entered, it determines the target lighting mode used to control the lighting of the target dual-port hard disk based on the obtained identification information and lighting mode control information, and determines the target controller that obtains lighting control rights under the target lighting mode.

[0067] The target lighting mode is a master-slave mode or a dual-active mode, and the target controller is one of the controllers 01 corresponding to at least two lighting analysis modules 12 .

[0068] The master-slave mode is pre-configured with one controller A of the two controllers 01 as the master controller (i.e., the target controller) and the other controller B as the slave controller. The master controller will first obtain control of a dual-port hard disk. When the master controller obtains control, the slave controller loses control.

[0069] Active-active mode does not pre-configure the control rights of the two controllers 01 over a dual-port hard drive. Instead, the lighting arbitration module 32 determines the order in which the two controllers 01 send their lighting control rights requests based on the time information. It then determines the target controller based on this order.

[0070] The lighting module 13 is configured to receive lighting information sent by the lighting analysis module 12 corresponding to the target controller, and control the lighting of the light of the target dual-port hard disk according to the lighting information.

[0071] If the target lighting mode is the master-slave mode, the target controller is the master controller A. The lighting module 13 obtains the lighting information sent by the master controller and controls the lighting of the corresponding dual-port hard disk according to the lighting information.

[0072] If the target lighting mode is the active-active mode, the lights of the corresponding dual-port hard disks are controlled to light up according to the lighting information sent by the target controller in the determined active-active mode.

[0073] Optionally, the lights that light up include but are not limited to: a presence light, an error indicator light, etc.

[0074] Optionally, the dual-port hard disk may be a dual-port NVMe hard disk.

[0075] In the above embodiment of the present application, the lighting control system further includes at least two lighting analysis modules 12 and a lighting module 13, the connection relationship of which is as follows: the at least two lighting analysis modules 12 are connected to the corresponding controller 01, the lighting module 13 is respectively connected to the lighting arbitration module 32 and the at least two lighting analysis modules 12, and the controllers 01 corresponding to the at least two lighting analysis modules 12 are also connected to the information processing module 31. The controllers 01 corresponding to the at least two lighting analysis modules 12 send identification information of the target dual-port hard disk to be controlled to the information processing module 31, the lighting arbitration module 32 determines the target controller that obtains lighting control rights in the target lighting mode, the target controller being one of the controllers corresponding to the at least two lighting analysis modules, the lighting module 13 receives the lighting information sent by the lighting analysis module corresponding to the target controller, and controls the lighting of the light of the target dual-port hard disk according to the lighting information. The lighting control system of this embodiment enables, when any dual-port hard disk is used by multiple controllers 01, the lighting arbitration module 32 can determine the target lighting mode used to control the lighting of the target dual-port hard disk based on the identification information and lighting mode control information sent by the information processing module 31. Since different lighting modes and control methods under different lighting modes are set, errors in the lighting control of any dual-port hard disk can be reduced, thereby achieving accurate control of the lighting of the dual-port hard disk.

[0076] Furthermore, based on the above embodiment, the following embodiment illustrates the lighting control process of a dual-port hard disk through a lighting control system when the target lighting mode is the master-slave mode.

[0077] If the target lighting mode is the master-slave mode, the lighting arbitration module 32 determines the target controller that obtains lighting control rights in the target lighting mode according to the identification information and the lighting mode control information. One possible implementation method is:

[0078] Obtain the first identification information of the first target controller pre-configured in the master-slave mode, and determine the first target controller that obtains the lighting control right in the master-slave mode, that is, the master controller, based on the first identification information, wherein the first target controller is one of the controllers 01 corresponding to at least two pre-configured lighting analysis modules 12.

[0079] See Figure 4 , Figure 4 This is a structural diagram of another lighting control system provided in an embodiment of the present application, which includes, in addition to an information processing module 31, a lighting arbitration module 32, at least two lighting analysis modules 12, a lighting module 13 and an in-place detection module 14, a timer monitoring module 15.

[0080] Among them, the timer monitoring module 15 is connected to the lighting arbitration module 32 and each controller 01 respectively, that is, connected to the first target controller. The timer monitoring module 15 is used to monitor the timer signal of the first target controller and send the timer signal of the first target controller to the lighting arbitration module 32.

[0081] The lighting arbitration module 32 receives in real time the timer signal of the first target controller sent by the timer monitoring module 15 , which may be a watchdog timer (WDT) signal, and determines whether the first target controller is in a normal working state based on the timer signal to obtain a determination result.

[0082] Specifically, if the timer signal undergoes a level flip within the preset time length, a judgment result is obtained that the first target controller is in a normal working state; if the timer signal does not undergo a level flip within the preset time length, a new timer signal is obtained after the first target controller is reset; if the new timer signal undergoes a level flip within the preset time length, a judgment result is obtained that the first target controller is in a normal working state; if the new timer signal does not undergo a level flip within the preset time length, a judgment result is obtained that the first target controller is in an abnormal working state.

[0083] The lighting arbitration module 32 determines whether the WDT signal of the first target controller flips between high and low levels within a preset time period (assuming 60 seconds) based on the WDT signal of the first target controller. If flipping occurs, it is determined that the first target controller is in a normal working state.

[0084] If no high-low level flip occurs within 60 seconds, the lighting arbitration module 32 determines that the first target controller is in an abnormal operating state. The lighting arbitration module 32 will send a node reset NODE_RST signal to the first target controller. The first target controller performs a reset operation based on the reset signal and regenerates the WDT signal. The lighting arbitration module 32 obtains the new WDT signal of the first target controller monitored by the timer monitoring module 15 after the reset. If the new WDT signal flips within 60 seconds, it is determined that the first target controller has returned to normal and returned to normal operating state. If the new WDT signal does not flip within 60 seconds, it is determined that the first target controller is in an abnormal operating state.

[0085] If the lighting arbitration module 32 determines that the first target controller is in a normal working state, it sends a determination result indicating that the first target controller is in a normal working state to the lighting module 13 , so that the lighting module 13 performs a lighting operation.

[0086] In this embodiment, the lighting module 13 further includes a plurality of multiplexers 131 and a dual-port hard disk lighting control module 132 . The dual-port hard disk lighting control module 132 may include a plurality of sub-dual-port hard disk lighting control modules.

[0087] For any multiplexer 131 , the multiplexer 131 is respectively connected to the lighting arbitration module 32 , at least two lighting analysis modules 12 , and the dual-port hard disk lighting control module 132 .

[0088] In this embodiment, the lighting arbitration module 32 is further configured to determine a target multiplexer from the multiple multiplexers 131 included in the lighting module 13 according to the identification information of the target dual-port hard disk to be controlled.

[0089] Optionally, the lighting module 13 includes multiple multiplexers 131, and each multiplexer 131 corresponds to its own dual-port hard disk. Therefore, the lighting arbitration module 32 can determine the target multiplexer corresponding to the target dual-port hard disk based on the identification information. In this embodiment, the dual-port hard disk corresponding to each multiplexer 131 is preset.

[0090] The lighting information sent by the lighting analysis module 12 corresponding to the first target controller can be sent to the dual-port hard disk lighting control module 132 through the preset path of the target multiplexer, wherein the preset path is a pre-configured path that allows the lighting information sent by the first target controller to pass through.

[0091] After receiving the lighting information, the dual-port hard disk lighting control module 132 controls the light of the target dual-port hard disk corresponding to the identification information to light up.

[0092] Optionally, the lighting information includes but is not limited to: identification information of the target dual-port hard disk, an electrical fuse (eFuse) control signal, and a preset instruction type, etc., wherein the preset instruction type includes but is not limited to: an error instruction, a positioning instruction, and a rebuild instruction, etc.

[0093] The dual-port hard disk lighting control module 132 determines the target dual-port hard disk to be controlled based on the identification information of the target dual-port hard disk, controls the target dual-port hard disk to be powered on according to the thermal fuse control signal, so that the target dual-port hard disk enters the power-on working state, and controls the light corresponding to the instruction type in the target dual-port hard disk to light up according to the instruction type.

[0094] In this embodiment, if the lighting arbitration module 32 determines that the first target controller is still in an abnormal operating state after being reset, it obtains the second identification information of a second target controller pre-configured in the master-slave mode and, based on the second identification information, determines the second target controller, i.e., the slave controller, that has obtained lighting control authority in the master-slave mode. The second target controller is the other controller 01 corresponding to the at least two lighting analysis modules 12, excluding the first target controller.

[0095] If the lighting arbitration module 32 determines that the new WDT signal after the first target controller is reset does not flip within the preset time period, assuming 60 seconds, it means that the first target controller has not recovered to normal, and the first target controller is in an abnormal working state.

[0096] After determining that the first target controller is in an abnormal working state, the lighting arbitration module 32 controls the lighting of the corresponding target dual-port hard disk according to the lighting information sent by the second target controller pre-configured in the master-slave mode.

[0097] Before controlling the lighting of the corresponding target dual-port hard drive based on the lighting information sent by the second target controller, the lighting arbitration module 32 needs to obtain the timer signal of the second target controller monitored by the timer monitoring module 15. Based on the timer signal of the second target controller, the module determines whether the second target controller is in normal operation and obtains a determination result. If the determination result indicates that the second target controller is in normal operation, the module transmits the determination result to the lighting module 13, which then controls the lighting of the target dual-port hard drive based on the lighting information sent by the lighting analysis module 12 corresponding to the second target controller.

[0098] The specific judgment process is similar to the above-mentioned process of judging whether the first target controller is in a normal working state, and will not be described again to avoid redundancy.

[0099] If the lighting arbitration module 32 determines that the second target controller is operating normally, it controls the lighting of the corresponding target dual-port hard drive according to the lighting information command sent by the second target controller. The process of controlling the lighting of the corresponding target dual-port hard drive according to the lighting information command sent by the second target controller is the same as the process of controlling the lighting of the corresponding target dual-port hard drive according to the lighting information command sent by the first target controller. To avoid redundancy, the description is not repeated here.

[0100] If the lighting arbitration module 32 determines that the second controller is in an abnormal working state, it generates a fault instruction and sends the fault instruction to the lighting module 13, so that the lighting module 13 controls the lamp indicating the fault in the target dual-port hard disk to light up according to the fault instruction.

[0101] Optionally, in addition to controlling the light indicating a fault in the corresponding target dual-port hard disk to light up, the light indicating a system fault on the dual-port hard disk backplane can also be controlled to light up according to the fault instruction. The light indicating a system fault is different from the light indicating a fault in the dual-port hard disk.

[0102] In the above-described embodiment of the present application, the lighting arbitration module 32 determines whether the first target controller is in normal operating state based on the timer signal of the first target controller monitored by the timer monitoring module 15 and the timer signal. If the first target controller is determined to be in normal operating state, a judgment result indicating that the first target controller is in normal operating state is obtained and sent to the lighting module 13, so that the lighting module 13 controls the lighting of the target dual-port hard drive based on the lighting information obtained from the first target controller. If it is determined that the first target controller is still in an abnormal operating state after being reset, the lighting of the target dual-port hard drive is controlled based on the lighting information sent by the second target controller pre-configured in the master-slave mode. The method of this embodiment enables, when a dual-port hard drive is used by multiple controllers 01, the lighting control system can control the lighting of the dual-port hard drive according to the control method in the master-slave mode, thereby improving the accuracy of the dual-port hard drive lighting control.

[0103] Furthermore, based on the above embodiment, the following embodiment illustrates the lighting control process of a dual-port hard disk when the target lighting mode is the active-active mode by using the above lighting control system.

[0104] The structure of the lighting control system in this embodiment is the same as that in the above embodiment, and will not be described again in this embodiment.

[0105] In the active-active mode, the lighting arbitration module 32 determines the target controller that obtains lighting control rights in the target lighting mode based on the identification information and the lighting mode control information. One possible implementation is:

[0106] The lighting arbitration module 32 obtains the time information of the lighting control right application request sent by each controller 01 from the information processing module 31 .

[0107] Taking two controllers 01 as an example, the information processing module 31 obtains the time information when the two controllers 01 send the lighting control right application request.

[0108] After the lighting arbitration module 32 obtains the time information of the two controllers 01 sending the lighting control right application request, if it is determined based on the time information that each controller 01 sent the lighting control right application request simultaneously, it determines a third target controller based on pre-configured permission control information, wherein the permission control information specifies one of the controllers 01 corresponding to the at least two lighting analysis modules 12 as the third target controller. If it is determined based on the time information that each controller 01 sent the lighting control right application request non-simultaneously, the controller 01 that sent the lighting control right application request first is determined as the third target controller.

[0109] Optionally, after obtaining the time information of the two controllers 01 sending the lighting control right application requests, the lighting arbitration module 32 determines the time sequence in which the two controllers 01 send the lighting control right application requests.

[0110] For example, assuming two controllers, controller A and controller B, there are three possible situations for the time sequence determined based on the time information:

[0111] The first one is: controller A sends a request for the lighting control right first, and then controller B sends a request for the lighting control right.

[0112] The second method is: controller B first sends a request for the lighting control right, and then controller A sends a request for the lighting control right.

[0113] The third type is: controller A and controller B send lighting control right application requests at the same time.

[0114] The lighting arbitration module 32 determines whether the two controllers 01 send lighting control right application requests at the same time according to the time sequence, and obtains a determination result.

[0115] If the judgment result indicates that at least two controllers 01 simultaneously send requests for lighting control rights, the third target controller is determined based on the pre-configured permission control information, i.e., the third scenario described above. The lighting arbitration module 32 then determines, based on the pre-configured permission control information, whether controller A is designated as the third target controller or controller B.

[0116] If the judgment result indicates that the two controllers 01 did not send the lighting control right application request simultaneously, the controller 01 that sent the lighting control right application request first is determined as the third target controller. That is, if it is the first case, the third target controller is controller A, and if it is the second case, the third target controller is controller B.

[0117] The lighting arbitration module 32 obtains the timer signal of the third target controller through the timer monitoring module 15 , wherein the timer signal may be a watchdog timer (WDT) signal.

[0118] The lighting arbitration module 32 determines whether the third target controller is in a normal working state according to the timer signal. The specific judgment process is similar to the process of determining whether the first target controller is in a normal working state in the above embodiment. Please refer to the above embodiment. To avoid redundancy, it will not be repeated.

[0119] If the lighting arbitration module 32 determines that the third target controller is in a normal working state, it sends the determination result indicating that the third target controller is in a normal working state to the lighting module 13 so that the lighting module 13 performs a lighting operation.

[0120] If the lighting arbitration module 32 determines that the third target controller is in an abnormal working state or the third target controller is in a normal working state but automatically gives up the control right, that is, the WDT signal of the third target controller does not flip within a preset time length, such as 60 seconds, the lighting arbitration module 32 waits to obtain the time information of the new lighting control right application request sent by the above two controllers 01, and then continues to execute the steps in this embodiment.

[0121] It should be noted that in the present application, if the instruction sent by the third target controller is not a lighting instruction, that is, it is not one or more of an error instruction, a positioning instruction, and a reconstruction instruction, then the lighting module 13 obtains the lighting information sent by another controller, wherein the other controller is the other controller other than the third target controller in the controller 01 corresponding to the two lighting analysis modules 12, and controls the corresponding dual-port hard disk light to light up according to the lighting information sent by the other controller.

[0122] In active-active mode, the indicator lights are as shown in Table 1:

[0123] Table 1

[0124]

[0125] Among them, the non-lighting instruction means that it is not any of the error instructions, positioning instructions and reconstruction instructions in the table, and "X" means that the instruction is ignored.

[0126] In active-active mode, if the third target controller doesn't issue an error, location, or rebuild command, the error and location commands from the other controllers that haven't taken control will still be acknowledged, and the corresponding dual-port hard drive's red or blue light will flash at a preset frequency, such as 0.5Hz. This design allows for timely detection of possible dual-port hard drive errors or failures, providing prompt notifications and helping system administrators accurately locate the dual-port hard drives. Furthermore, the LED behavior allows for quick identification of the current server system status.

[0127] In the above-described embodiment of the present application, the lighting arbitration module 32 obtains the time information of the lighting control request sent by each controller 01 from the information processing module 31 and determines the third target controller based on the time information. After determining the third target controller, the timer signal of the third target controller is obtained. If the timer signal determines that the third target controller is in normal operation, the light of the target dual-port hard drive is controlled to be illuminated according to the lighting information sent by the third target controller. The method of this embodiment enables, when a dual-port hard drive is used by multiple controllers, the lighting control system can control the lighting of the dual-port hard drive according to the control method in the active-active mode, thereby improving the accuracy of the dual-port hard drive lighting control.

[0161] It is understandable that this embodiment does not limit the execution order in the master-slave mode and the active-active mode, and the above embodiment is only for illustration.

[0162] For the specific implementation details and effects of each step, please refer to the above multiple embodiments. To avoid repetition, detailed description will be omitted.

[0163] In related technologies, since the lighting control system usually only supports a single controller to exclusively control a specified hard disk, for example, it can only support hard disk 0 to be controlled by controller A. Therefore, after the lighting control system obtains the SMART information or resource information of hard disk 0, controller A can only obtain the SMART information or resource information of hard disk 0 through the lighting control system through the I2C bus, and the information of other hard disks cannot be obtained and accessed.

[0164] In this application, the lighting control system can poll and activate the I2C switch conversion module on the dual-port hard drive backplane to obtain SMART information, resource information, or control information sent by the controller for each dual-port hard drive. It can also package the power-off information and lighting status of each dual-port hard drive into a frame. In this application, each controller is also provided with a corresponding dual-port random access memory (DPRAM). After packaging this data, the lighting control system sends or copies the packaged frame to the corresponding DPRAM of each controller, allowing each controller to access information from other hard drives to achieve information synchronization.
