Description

Technical Field

Especially for the design of high-speed hard disks, signal integrity has become particularly important. Traditional server storage design uses a front hard disk backplane, such as Figure 1 As shown, the front hard disk backplane refers to the hard disk backplane installed on the front of the server chassis. The front of the hard disk backplane is provided with a hard disk slot, which is used to install and fix a hard disk (such as HDD (Hard Disk Drive, mechanical hard disk) or SSD (Solid State Drive, solid state drive)); the back of the hard disk backplane provides a high-speed connection interface for data transmission with the server's mainboard or other storage controller through a cable.

[0051] The core of the present invention is to provide a hard disk backplane, a server, a hard disk control method and a device. The hard disk can be directly inserted into the hard disk backplane, and there is no need to use a high-speed cable to connect the mainboard and the hard disk backplane, thereby shortening the signal transmission path, reducing signal loss, reducing the number of cables, optimizing the heat dissipation space, and improving system performance and reliability.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0053] First, as Figure 2 , Figure 3 and Figure 4 As shown, the present application provides a hard disk backplane, which is applied to a server, and the hard disk backplane includes:

[0054] Printed circuit board, plug-in connector 1;

[0055] The plane where the printed circuit board is located is perpendicular to the plane where the mainboard in the server is located. The printed circuit board is directly connected to the slot 2 on the mainboard through a plug-in connector 1. A plurality of hard disk interfaces 3 are arranged on the front or back of the printed circuit board, and each hard disk interface 3 is used to insert a corresponding hard disk.

[0056] A signal transmission link is also provided on the printed circuit board, and the signal transmission link is configured to transmit signals between the hard disk interface 3 and the plug-in connector 1 .

[0057] The traditional server hard disk backplane design usually requires the use of high-speed signal cables to connect the motherboard to the hard disk interface 3. This design has several significant problems. First, long-distance signal transmission lines will lead to increased signal loss, especially when using high-speed signal transmission, the signal quality is difficult to guarantee. Secondly, the use of complex high-speed cables will lead to cumbersome wiring, increase the difficulty of wiring, and make the design of the entire system more complicated. In addition, due to the large number of cables and the need to occupy space in the chassis, the heat dissipation effect is often affected, affecting the heat dissipation effect of the hard disk and motherboard, thereby reducing the stability and reliability of the system.

[0058] Different from the traditional design, the hard disk backplane design of the present invention avoids the cumbersome cable connection through the direct connection between the printed circuit board and the plug-in connector 1. In this design, the printed circuit board (PCB) and the mainboard are directly connected by the plug-in connector 1 (specifically, it can be a gold finger) and the slot 2 (the slot 2 on the mainboard can be but not limited to a PCIE slot). This connection method significantly shortens the signal transmission path, reduces signal loss, and improves the quality of signal transmission. As a key component connecting the mainboard and the backplane, the plug-in connector 1 ensures high-quality signal transmission through close contact with the mainboard slot 2, and avoids interference and attenuation problems that may be introduced in the cable connection.

[0059] In addition, the design of the hard disk backplane integrates multiple hard disk interfaces 3 on the printed circuit board, each hard disk interface 3 is used to insert the corresponding hard disk, and a dedicated signal transmission link is also set on the hard disk backplane. These links are responsible for transmitting signals between the hard disk interface 3 and the plug-in connector 1, thereby further simplifying the design and reducing the number of hardware components. Under this structure, the hard disk can be directly inserted into the hard disk backplane, and no longer needs to be connected to the motherboard through traditional cables. This not only effectively shortens the signal transmission path, but also reduces the number of high-speed signal lines used in the system, further reducing signal loss and interference.

[0060] Through this design, the hard disk backplane can significantly optimize the space utilization inside the server. The reduced cables and connection components free up the space that was originally occupied, providing more space for other components (such as fans, radiators, etc.). This optimization can effectively improve the heat dissipation effect of the chassis, avoid the problem of poor heat dissipation caused by too many cables occupying space, thereby improving the working environment of the hard disk and motherboard and ensuring the stable operation of the system.

[0061] In addition, the hard disk backplane simplifies the server design and assembly process by reducing the use of complex cables and optimizing signal transmission. The simplification of hardware connections not only reduces production and maintenance costs, but also improves the overall reliability of the system. Since the physical connection of the cables is reduced, the failure rate of the overall system is also expected to be reduced, thereby improving the stability of the server.

[0062] In summary, the hard disk backplane design of the present invention improves the signal transmission quality while reducing signal loss, simplifying the design and wiring, optimizing the heat dissipation space, and improving the overall performance and reliability of the system through the innovative printed circuit board and plug-in connector 1 structure. This design not only solves various problems in the traditional hard disk backplane design, but also makes significant improvements in cost, maintenance and system stability.

[0063] like Figure 6As shown, as an optional embodiment, it also includes:

[0064] A control module, whose input end is connected to the bus of the mainboard, and whose output end is respectively connected to one end of a plurality of indicating devices, and the plurality of indicating devices correspond one to one with the plurality of hard disk interfaces 3;

[0065] The control module is configured to parse the status information of the hard disk obtained by the mainboard, determine the faulty hard disk with abnormal status, and switch to the prompt channel corresponding to the faulty hard disk;

[0066] The indicating device is configured to output preset prompt information when the prompt channel corresponding to itself is connected and itself is powered on.

[0067] In this embodiment, the hard disk backplane design further enhances the fault detection and prompting functions, and adds a control module and several indicator devices for real-time monitoring of the hard disk status and fault alarm.

[0068] Specifically, the input end of the control module is connected to the bus on the mainboard, and can receive the hard disk status information transmitted by the mainboard. The mainboard obtains the working status of the hard disk in real time through the bus, such as whether the hard disk is operating normally, whether there is a fault, whether there is performance degradation, etc. The control module analyzes the received hard disk status information to determine whether there is a faulty hard disk, and when a fault occurs, controls its output end to switch to the corresponding indication device to provide timely fault prompts.

[0069] Each hard disk interface 3 corresponds to an indicator device, and the position of the indicator device matches the hard disk interface 3, ensuring that the fault information of each hard disk can be displayed or alarmed through the corresponding indicator device. After receiving the signal from the control module, the indicator device will output the preset prompt information when the corresponding prompt channel is connected and it is powered on. These prompt information can be visual, sound or other forms of warning signals, such as flashing LED lights, sound alarms, etc., to remind server administrators or operators to pay attention to the hard disk status in time and take necessary processing measures.

[0070] In this way, the coordinated work of the control module and the indicator device enables the system to give timely and intuitive warnings when the hard disk fails or is abnormal, greatly improving the fault response speed and system maintenance efficiency. By real-time monitoring of the hard disk status and dynamically adjusting the prompt channel of the indicator device, the administrator can directly obtain specific information about the hard disk failure through the intuitive indicator device without using complex diagnostic tools, reducing troubleshooting time and improving system reliability and maintainability. This design has significant application advantages in improving the maintainability of server systems, reducing downtime, and ensuring data security.

[0071] As an optional embodiment, it also includes:

[0072] An indicating switch, the input end of which is connected to the other end of a plurality of indicating devices, and the output end of which is grounded;

[0073] The indicator switch is configured to close when the control module identifies an abnormal faulty hard disk, so that the indicator device is powered on.

[0074] In this embodiment, the detection and indication function of the faulty hard disk is further enhanced, and an indication switch (such as a button switch) is added. The switch is connected to the other end of the indication device and is regulated by the control module.

[0075] Specifically, the input end of the indicator switch is connected to the other end of the multiple indicator devices, and the output end is grounded. When the control module identifies a hard disk failure or abnormality, the indicator switch will be triggered to close, and then the corresponding indicator device will be powered on through a control signal.

[0076] In terms of working principle, the control module continuously monitors the hard disk status and analyzes the hard disk health information transmitted through the bus. When an abnormal state of a hard disk is detected, such as a hard disk failure, overload or abnormal temperature, the control module identifies the faulty hard disk and activates the indicator switch (the indicator switch can be closed manually in addition to being controlled by the control module). At this time, the indicator switch is closed, the circuit is turned on, and the indicator device corresponding to the hard disk receives power, starts and lights up or sends out other warning signals (such as flashing LED lights, sound alarms, etc.).

[0077] Through this design, the indicator switch plays a role in strengthening the connection between the indicator device and the control module. When a hard disk fails, the fault indicator device can work normally by closing the switch, and promptly remind the server operator. Once the indicator device is powered on and sends a preset prompt message (such as lighting, flashing, etc.), the administrator can quickly locate the hard disk with the problem and then handle it in time, avoiding data loss or system performance degradation caused by hard disk failure. This precise control of the indicator device through a physical switch improves the immediacy of fault response and the visibility of the indication information, making the system more reliable and easy to maintain.

[0078] As an optional embodiment, it also includes:

[0079] an energy storage device (which may be a capacitor) configured to store energy;

[0080] A first power supply path, an input end of which is connected to a first power supply of the hard disk, and an output end of which is connected to a power supply end of the control module;

[0081] A second power supply path, an input end of which is connected to the energy storage device, and an output end of which is connected to the power supply end of the control module;

[0082] The first power supply path is configured to be closed when the first power supply of the hard disk is online, so that the first power supply supplies power to the control module;

[0083] The second power path is configured to be closed when the first power supply is offline so that the energy storage device can power the control module.

[0084] In this embodiment, in order to enhance the diagnosis and maintenance functions of the hard disk backplane in an offline state, a combined structure of an energy storage device and a power supply path is designed.

[0085] Specifically, the system provides a stable power supply for the control module through the first power supply path and the second power supply path, and ensures that the control module can still work normally even when the first power supply of the hard disk is offline.

[0086] First, the input end of the first power path is connected to the first power supply of the hard disk, and the output end is connected to the power supply end of the control module. When the first power supply of the hard disk is in an online state, the first power path is closed, so that the first power supply of the hard disk provides power to the control module, ensuring that the control module can detect the status information of the hard disk in a timely manner under normal working conditions.

[0087] However, if the first power supply of the hard disk fails or is cut off, the second power path will automatically intervene. The input end of the second power path is connected to the energy storage device, which is responsible for storing a certain amount of energy and providing power when the first power supply is offline. At this time, the second power path is closed and the energy in the energy storage device is transmitted to the control module to ensure that the control module continues to operate and can perform hard disk status diagnosis and indication functions. In this way, the control module can continue to diagnose and monitor data through the backup power supply even if there is a problem with the hard disk power supply.

[0088] The power switching function of the first power path and the second power path can be achieved by using diodes, thereby simplifying the design and ensuring automatic switching of power supply. The role of the diode in the circuit is unidirectional conduction, ensuring that the current flows only in one direction, which is very useful when switching power and preventing power interference. In order to ensure that the control module preferentially obtains power from the first power supply of the hard disk, a diode can be used in the first power path. The positive pole of the diode is connected to the first power supply of the hard disk, and the negative pole is connected to the power supply terminal of the control module. The role of the diode is that when the first power supply of the hard disk is online, the current flows to the control module through the diode to provide power for it. At this time, the unidirectional conductivity of the diode prevents other power supplies from passing, ensuring that the control module only obtains power from the first power supply of the hard disk. When the first power supply is offline or fails, the role of the second power path is to provide backup power for the control module. In order to achieve this function, a diode can also be used in the second power path. The positive pole of the diode is connected to the energy storage device, and the negative pole is connected to the power supply terminal of the control module. When the first power supply is offline, the energy storage device provides power to the control module through the diode. Due to the unidirectional conductivity of the diode, the current can only flow from the energy storage device to the control module, ensuring that the energy storage device can take over the power supply and avoiding any current flowing back to the energy storage device. The diode can ensure that the current flows only in the predetermined direction, thereby avoiding interference or reverse current flow between the first power supply and the second power supply. The use of diodes can simply realize the automatic switching of power supplies without complex switching circuits or control signals, reducing design complexity and system costs.

[0089] In addition, since the plug-in hard disk backplane is usually located inside the server chassis, it is difficult to directly perform maintenance and fault diagnosis using the traditional backplane indicator lights. Therefore, the present invention implements an offline hard disk status diagnosis design. In the event of a power failure or hard disk detachment, the energy storage device can still provide the necessary power support to achieve diagnosis and maintenance of the hard disk status. In this way, it not only ensures that the system can continue to monitor the status of the hard disk when the hard disk is offline or powered off, but also facilitates maintenance personnel to conduct timely troubleshooting and processing when the server cannot be turned on normally, significantly improving the maintainability and reliability of the server.

[0090] As an optional embodiment, it also includes:

[0091] A first controllable switch, a first end of which is respectively connected to the control end of the first controllable switch, the second power supply of the hard disk and the ground end, and a second end of which is connected to the input end of the energy storage device;

[0092] The first controllable switch is configured to be closed when the second power supply is online, so that the second power supply charges the energy storage device.

[0093] In an optional embodiment of the present invention, the function of the first controllable switch is to control the second power supply to charge the energy storage device. Specifically, the first controllable switch is closed when the second power supply is online, so that the second power supply can provide charging current to the energy storage device. This means that when the second power supply is working normally and providing power, the first controllable switch will be triggered to close, thereby establishing a current path between the second power supply and the energy storage device, allowing current to flow to the energy storage device and charge. Ensure that the energy storage device can be used as a backup power supply when the first power supply of the hard disk is offline, ensuring continuous power supply to other system components such as the control module.

[0094] As an optional embodiment, it also includes:

[0095] A hard disk switching module, whose input end is connected to the bus of the mainboard, and whose output end is respectively connected to a plurality of hard disk interfaces 3;

[0096] The hard disk switching module is configured to determine the target hard disk according to the target access instruction, and switch to the bus channel corresponding to the target hard disk, so that the mainboard obtains the status information of the target hard disk through the bus channel.

[0097] In an optional embodiment of the present invention, the hard disk switching module is used to dynamically switch to the bus channel corresponding to the target hard disk according to the target access instruction, so that the mainboard can obtain the status information of the target hard disk through the channel. Specifically, the hard disk switching module realizes the selective access to the hard disk status information, optimizes the data transmission path between the mainboard and the hard disk, and improves the efficiency and reliability of the system.

[0098] Specifically, the input end of the hard disk switching module is connected to the bus of the mainboard, which is usually used to connect the data transmission between the mainboard and multiple hard disks. The mainboard sends instructions and receives hard disk status information through the bus. The hard disk switching module determines which hard disk status information needs to be accessed by reading the access instruction sent by the mainboard. The output end of the hard disk switching module is respectively connected to multiple hard disk interfaces 3. Each hard disk interface 3 corresponds to a hard disk, and the hard disk switching module can switch the signal path by controlling these interfaces, thereby transmitting the status information of the target hard disk to the mainboard.

[0099] The working principle of the hard disk switching module is as follows: the hard disk switching module receives access instructions from the mainboard through the bus. These instructions usually include information such as the identification of the target hard disk to be accessed (such as the hard disk number or address), the instruction type (such as reading the hard disk status, obtaining data, etc.). The hard disk switching module parses the received instructions and determines the target hard disk to be accessed. The instruction contains the identification information of the hard disk or the channel number of the target hard disk. The hard disk switching module selects the hard disk interface corresponding to the target hard disk based on this information 3. Once the target hard disk is determined, the hard disk switching module connects the mainboard bus to the interface of the target hard disk through the switching circuit. This means that the mainboard can now communicate with the target hard disk through the specified bus channel to obtain the status information of the hard disk or perform other operations (such as reading data, performing write operations, etc.). By switching to the bus channel of the target hard disk, the hard disk switching module enables the mainboard to obtain the status information of the target hard disk. This status information includes the operating status, temperature, service life, fault information, etc. of the hard disk, and the mainboard uses this information for further monitoring or troubleshooting.

[0100] In traditional systems, each hard disk has an independent bus connection, which may lead to bus redundancy and resource waste. However, through the hard disk switching module, multiple hard disks can share the same bus, reducing the complexity of the bus and the connection cost. The hard disk switching module can automatically select the hard disk and switch the bus channel according to the access command issued by the motherboard, thereby simplifying the management of the hard disk. The motherboard only needs to send the access command of the target hard disk, and the hard disk switching module is responsible for processing the switching logic and automatically transmitting the status information of the target hard disk to the motherboard. The hard disk switching module allows the system to flexibly select different hard disks for access and adapt to a variety of different application requirements. The system can dynamically switch the target hard disk according to actual needs, which improves the scalability and flexibility of the system. By intelligently switching the bus channel, the system can quickly respond to the motherboard's access request, avoiding unnecessary bus congestion and delay, thereby improving the efficiency of obtaining hard disk status information and optimizing system performance.

[0101] In large-scale storage systems, the hard disk switching module can make hard disk management more efficient and reduce hardware costs by allowing multiple hard disks to share the same bus. In applications that require monitoring of multiple hard disks, the hard disk switching module can enable the mainboard to obtain real-time status by switching to the correct hard disk interface 3, making it easier for system administrators to perform hard disk maintenance, status checks, or troubleshooting.

[0102] In summary, the hard disk switching module in this embodiment simplifies the access process of hard disk status information by automatically identifying the access command of the motherboard and switching to the bus channel corresponding to the target hard disk. It can not only optimize the connection between the hard disk and the motherboard and reduce redundant connections, but also improve the flexibility, scalability and efficiency of the system. This design helps to improve the intelligent level of hard disk management and provides a more efficient solution for complex storage systems.

[0103] In addition, as a preferred embodiment, it can also include: adding a temperature sensor and a temperature control module to the hard disk backplane, the temperature sensor is configured to monitor the temperature of the hard disk backplane in real time; the temperature control module is configured to start the server's heat dissipation system when the temperature of the hard disk backplane is too high to prevent the hard disk from being damaged due to overheating. For example, when the temperature of the hard disk backplane is too high, the fan speed is automatically adjusted to optimize the cooling effect.

[0104] In this embodiment, a temperature sensor and a temperature control module are added to the hard disk backplane to realize real-time temperature monitoring and intelligent temperature control management of the hard disk backplane. Specifically, the temperature sensor is configured to continuously monitor the temperature of the hard disk backplane and feed back the real-time temperature data to the temperature control module. The temperature control module makes a judgment based on the received temperature information. When the temperature of the hard disk backplane exceeds the preset safety threshold, the temperature control module automatically starts the server's heat dissipation system to prevent the hard disk from being damaged by overheating due to excessive temperature, thereby ensuring the normal operation of the hard disk. The temperature control module can not only start heat dissipation devices such as fans, but also intelligently adjust the fan speed according to the real-time temperature of the hard disk backplane to optimize the cooling effect. When the temperature is too high, the fan speed will increase to improve the heat dissipation effect; when the temperature returns to the normal range, the fan speed can be appropriately reduced, thereby achieving energy efficiency optimization and reducing unnecessary power consumption. In addition, the system can also adjust the air duct design and cooling mode in real time according to the feedback of the temperature sensor to further improve the overall heat dissipation effect. This intelligent temperature control design not only ensures the stable operation of the hard disk under high load conditions, but also avoids hard disk failures caused by overheating, thereby improving the reliability and service life of the server.

[0105] In a second aspect, the present application provides a server, including a mainboard and a hard disk backplane as described above, wherein the hard disk backplane is directly inserted into the slot 2 of the mainboard.

[0106] like Figure 5 As shown, as an optional embodiment, there are multiple hard disk backplanes, and each hard disk backplane is connected to a number of hard disks corresponding to a number of hard disk interfaces 3;

[0107] The multiple hard disk backplanes are connected to the multiple slots 2 of the mainboard in a one-to-one correspondence.

[0108] In the server design provided in the present application, the configuration mode of the hard disk backplane is flexible and extensible. The server includes a mainboard and multiple hard disk backplanes, each of which is directly inserted into a slot 2 on the mainboard to achieve electrical connection with the mainboard. There are multiple hard disk backplanes, and each hard disk backplane is equipped with multiple hard disk interfaces 3, which correspond to multiple hard disks one by one. Through this design, the server can achieve the integration and management of multiple hard disks and improve storage capacity and performance.

[0109] Specifically, multiple hard disk backplanes are connected to multiple slots 2 on the mainboard in a one-to-one correspondence to form a flexible hard disk expansion system. Each hard disk backplane not only provides an insertion and connection interface for the hard disk, but can also be managed as an independent modular unit. The design of the hard disk backplane allows users to increase or decrease the number of hard disks as needed and flexibly configure storage space. This modular design makes it easier to replace and maintain hard disks, while improving the scalability of the server.

[0110] Each hard disk backplane and the connected hard disks can be combined into a memory module, which means that a hard disk backplane can be regarded as a logical storage unit and can be operated and managed independently of other backplanes. For example, in a multi-hard disk backplane configuration, each backplane provides different storage requirements, such as RAID configuration or distributed storage, so that the server can load balance or failover between different hard disk backplanes, improving the reliability and flexibility of the system.

[0111] Through this design, the server can customize storage solutions according to actual needs. Whether it is expanding storage capacity or achieving more efficient hard disk management and more flexible fault recovery mechanisms, it can be achieved within this design framework.

[0112] For other introductions to the server, please refer to the above embodiments, and this application will not go into details here.

[0113] On the third aspect, the present application provides a hard disk control method, which is applied to the hard disk backplane as mentioned above. The hard disk control method aims to achieve accurate access and status diagnosis of the hard disk by working in collaboration with the baseboard management controller (BMC) on the mainboard, and to prompt faulty hard disks through an indication device.

[0114] like Figure 7 As shown, the hard disk control method includes:

[0115] S11: Obtain a target access instruction issued by a baseboard management controller in the mainboard, and determine a target hard disk according to the target access instruction;

[0116] In this step, the target access instruction is first received from the baseboard management controller (BMC) on the motherboard. As the control core of the server, the BMC is responsible for monitoring the hardware status and receiving instructions from the operating system or administrator. The target access instruction is to specify the hard disk device that needs to be accessed. It can be the serial number or other identifier of the hard disk, which is used to specify the target hard disk that needs to be monitored or operated.

[0117] S12: triggering and turning on a target bus channel corresponding to the target hard disk, where the target bus channel is a data transmission channel between a data access terminal of the target hard disk and a baseboard management controller;

[0118] In this step, the data transmission channel (i.e., target bus channel) corresponding to the target hard disk is activated through the hard disk control module. The bus channel is the data transmission path between the hard disk and the baseboard management controller (BMC), ensuring that the hard disk can be accessed smoothly. After activating the target bus channel, the baseboard management controller can access the hard disk data, including the hard disk log information, status data, etc.

[0119] S13: controlling the baseboard management controller to obtain log information of the target hard disk according to the target bus channel;

[0120] Once the data transmission channel is activated, the baseboard management controller can communicate with the hard disk through the channel to obtain the log information of the target hard disk. The hard disk log usually records important information such as the health status, performance data, error log, etc. of the hard disk. These log data are helpful for diagnosing the working status of the hard disk and potential problems.

[0121] S14: determining the status information of the target hard disk from the log information;

[0122] In this step, the baseboard management controller extracts the hard disk status information from the hard disk log information. This status information includes the hard disk health status, temperature, voltage and other monitoring data, which represents the current operation status of the hard disk. By analyzing the log, valuable information about whether the hard disk is in normal operation can be obtained.

[0123] S15: identifying a preset keyword from the status information, where the preset keyword is a keyword that indicates hard disk abnormality;

[0124] In this step, the extracted status information is analyzed to see if it contains preset keywords, such as "fail" or "error". These preset keywords are used to identify abnormal signals of the hard disk. For example, "fail" may mean that some components of the hard disk have failed, or the hard disk is not working properly. Through these keywords, the system can quickly identify abnormal status of the hard disk.

[0125] S16: when the preset keyword is identified, determining the abnormal hard disk corresponding to the status information including the preset keyword;

[0126] Once the system recognizes that the log information contains the preset keywords, it can confirm that the status of the hard disk is abnormal and mark it as a faulty hard disk. For example, if the log information contains the keyword "fail", it will know that the target hard disk has failed and needs further processing. At this time, the system will mark the relevant information of the faulty hard disk as "abnormal" and prepare to perform subsequent operations.

[0127] S17: Sending a control signal to the indicating device corresponding to the abnormal hard disk, so that the indicating device sends a corresponding prompt message.

[0128] Finally, a control signal is sent to the indicator device corresponding to the faulty hard disk. According to the control signal, the indicator device can issue prompt information through lights, displays or other means. For example, the indicator light may flash or turn red, indicating that there is a problem with the hard disk, which is convenient for administrators to find and deal with hard disk failures in a timely manner. This prompt information helps to quickly locate the faulty hard disk, reduce downtime caused by hard disk problems, and improve server reliability and maintenance efficiency.

[0129] Through the above steps, the hard disk status monitoring and fault response are more timely and accurate, ensuring the efficiency and reliability of the server storage system.
