Description

Technical Field

[0001] This application relates to the technical field of hard disks, and specifically to a hard disk tray position status monitoring device and method. Background Technology

[0002] The hard drive bays are located inside the server, and the hard drives are cooled by server fans. The overall integration density is high. When a hard drive in a bay fails and needs maintenance or replacement, maintenance personnel need to remove the bay to operate on the drive. Due to the large number of hard drives requiring maintenance, there's a possibility that the removal of the bay might go unnoticed by the backend system, potentially leading to data loss. Furthermore, the large number of hard drives requiring maintenance and the lengthy replacement process pose a significant challenge to cooling the other normally functioning hard drives, potentially leading to overheating due to the continuous accumulation of heat.

[0062] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0063] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0065] Example 1

[0066] This invention provides a hard drive tray position status monitoring device for use in servers, which can be implemented using standalone servers or server clusters composed of multiple servers. Specifically, such as... Figure 1 As shown, the server is provided with a slot for accommodating hard drives, and a hard drive bracket is installed in the hard drive slot. The device includes:

[0067] like Figure 2 As shown, there is a first identification element and a second identification element, wherein the first identification element is installed near the receiving port and is on the same plane as the receiving port, and the second identification element is installed on the hard disk tray, and the first identification element and the second identification element are located in the vertical direction of the same straight line.

[0068] A programmable logic device is communicatively connected to a first identifier and a second identifier, and obtains the pull-out distance of the hard disk tray through the first identifier and the second identifier;

[0069] A timer, set within the programmable logic device, is used to calculate the extraction time required for the hard disk tray to satisfy a preset extraction distance;

[0070] The baseboard management controller (BMC) is communicatively connected to a programmable logic device; when the hard disk tray is removed for a preset time, the controller controls the server to perform a protection operation.

[0071] It also includes a movable component, which is installed in the receiving slot and slidably connected to the hard drive tray. When the hard drive tray is pulled out for more than a preset time, it drives the hard drive tray back to its initial position.

[0072] It should be noted that the protection operations performed by the BMC control server include shutting down the control server or migrating data on the hard drive, and recording the removal of the hard drive tray as a security event in the BMC log.

[0073] In one specific embodiment, the system further includes a substrate management controller that accesses information on a programmable logic device via an integrated circuit bus, reads the extracted distance, and performs analysis in conjunction with a preset extracted distance.

[0074] It should be noted that, as Figure 3 As shown, in this embodiment, the first identification element is a magnetic element, and the second identification element is a magnetic detection switch. The magnetic detection switch can sense the magnetic element and the change of its magnetic field. When the distance between the two changes, the magnetic field detected by the magnetic detection switch also changes, thereby realizing the determination of the distance status between the hard drive tray and the server.

[0075] With the above settings, the hard drive tray is initially in its initial position, that is, the hard drive tray is installed in the server's receiving port. At this time, the first and second identification components are in their initial positions, and the status of the second identification component is displayed as LID ON, indicating that the hard drive tray has not been removed. When the hard drive tray is removed from the server, the second identification component senses the change in magnetism with the first identification component, and its status is displayed as LID off, thereby realizing the determination of whether the hard drive tray has been removed.

[0076] In a specific embodiment, such as Figure 4 As shown, the Complex Programmable Logic Device (CPLD) is mounted on the server backplane, and the CPLD communicates with the first and second identifiers via GPIO pins to obtain their status; at the same time, the CPLD is also connected to the disk management unit, which is interconnected with the CPLD via I2C, SGPIO, etc.

[0077] When the hard drive tray is detected to be removed from the server, the CPLD controls the timer to start counting. By pre-setting the removal time, for example, setting the removal time to 1 minute, when the timer exceeds 1 minute, the CPLD sends a command to the moving component, which then drives the hard drive tray back to its initial position.

[0078] To alert staff during actual operation when a hard drive tray is not promptly pushed back into the server after being removed, the device also includes an alarm unit, specifically comprising an LED light and a buzzer. When the hard drive tray is removed beyond a preset time (i.e., the tray is not removed), the alarm unit does not sound, and the indicator light remains off-green. When the hard drive tray is removed from the server, a timer in the CPLD begins counting. When the timer records that the removal time exceeds the preset time, the alarm unit activates, the LED light changes from green to red, and the buzzer sounds, reminding staff to address the issue promptly.

[0079] It should be noted that the operation instructions executed by the CPLD in this embodiment can also be implemented by the BMC through the I2C IOExpander.

[0080] To more accurately detect the distance the hard drive tray is pulled out of the server using the first and second identification components, the first identification component is installed on the upper part of the front side of the server chassis and is fixed in place by a connector, while the second identification component is installed on the side wall of the hard drive tray by a connector.

[0081] Specifically, the second identification component is installed away from the outer wall of the server when the hard drive tray is pulled out of the server. When the hard drive tray is pulled out of the server, the part away from the outer wall of the server is pulled out of the receiving slot first. Therefore, by installing the second identification component on the outer wall of the hard drive tray, the pulling distance of the hard drive tray from the server receiving slot can be monitored more accurately.

[0082] It should be noted that the connecting components in this embodiment include, but are not limited to, bolts and adhesives.

[0083] The solution in this embodiment can effectively identify the state of the hard drive tray being pulled out and detect the duration of the hard drive tray being pulled out. When the pulling time exceeds the safe time, the moving component is triggered to drive the hard drive tray back to the initial position, thereby avoiding the problem of overheating of the fault-free hard drive due to long hard drive maintenance time.

[0084] Example 2

[0085] The difference between this embodiment and Embodiment 1 is that both the first and second identification components are position sensors. One position sensor is installed at the bottom of the receiving slot and fixedly connected to the server, while the other position sensor is installed on the side wall of the hard drive tray. When the hard drive tray is on the server, it is in its initial position, meaning the distance between the two sensors is "0". When the hard drive tray is pulled out, the distance between the two position sensors continuously increases. When the distance between the two position sensors is within a preset pull-out distance range, a timer starts counting, and the hard drive tray can be maintained within the preset time. After the preset time has elapsed, the moving component automatically drives the hard drive tray back to its initial position.

[0086] Example 3

[0087] This application provides a method based on the hard disk tray position status monitoring device described above, which can be applied to, for example... Figure 5 In the application environment shown, terminal 102 communicates with server 104 via a network. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices.

[0088] In one embodiment, such as Figure 6 As shown, a method for monitoring the position status of a hard disk tray is provided, which can be applied to... Figure 5 Taking the terminal in the example, the explanation includes the following steps:

[0089] Step S1: Detect the position status of the hard drive tray using the first and second identification components;

[0090] Step S2: In response to the hard drive tray being pulled out, obtain the pulling distance of the hard drive tray being pulled out;

[0091] Step S3: If the extraction distance is within a preset range, the programmable logic device starts a timer to begin timing;

[0092] Step S4: When the timer's extraction time exceeds the preset time, the hard disk tray returns to its initial position under the action of the moving component.

[0093] In one specific embodiment, the display status of the first and second identification devices is read by the baseboard management controller to determine whether the hard disk tray has been removed;

[0094] When the indication status of the first and second identification elements is in place, the hard disk tray is not pulled out;

[0095] Alternatively, when the indication status of the first and second identification elements is not in place, the hard disk tray is pulled out;

[0096] In response to the hard drive tray being pulled out, the distance between the first identification element and the second identification element is obtained to obtain the pulling distance.

[0097] In one specific embodiment, the second identification element is installed away from the outer wall of the server when the hard disk tray is pulled out of the server; the first identification element and the second identification element are located in the vertical direction of the same straight line.

[0098] In one specific embodiment, the programmable logic device (PLD) obtains the pull-out distance of the hard disk tray through the first and second identifiers; and uses a timer to calculate the pull-out time of the hard disk tray to meet the preset pull-out distance. Simultaneously, the PLD communicates with the first and second identifiers through a general-purpose input / output port to acquire data information from the first and second identifiers.

[0099] In one specific embodiment, the substrate management controller is communicatively connected to the programmable logic device; it accesses information on the programmable logic device via the integrated circuit bus, reads the extraction distance, and performs analysis in conjunction with a preset extraction distance.

[0100] In one specific embodiment, when the hard drive tray is pulled out for a longer than a preset time, the LED light switches from green to red, and the buzzer starts to sound an alarm when the hard drive tray is pulled out for a longer than the preset time.

[0101] With the above settings, as Figure 7 As shown, when the server starts working, it can effectively identify the state of the hard drive tray being pulled out and detect the duration of the hard drive tray being pulled out. When the pulling time exceeds the safe time, the moving component is triggered to drive the hard drive tray back to the initial position, thereby avoiding the problem of overheating of fault-free hard drives due to long hard drive maintenance time.

[0102] It should be understood that, although Figure 6 and 7The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 6 and 7 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0103] Example 4

[0105] The acquisition module, in response to the hard drive tray being pulled out, acquires the pulling distance of the hard drive tray.

[0106] If the extraction distance is within a preset range, the programmable logic device starts a timer to begin timing.

[0107] The execution module, when the timer's extraction time exceeds a preset time, the hard disk tray returns to its initial position under the action of the moving component.

[0108] In one specific embodiment, it further includes a judgment module, used to read the display status of the first identification and the second identification through the baseboard management controller, so as to determine whether the hard disk tray has been pulled out; when the indication status of the first identification and the second identification is in place, the hard disk tray has not been pulled out;

[0109] Alternatively, when the indication status of the first and second identification elements is not in place, the hard disk tray is pulled out;

[0110] In response to the hard drive tray being pulled out, the distance between the first identification element and the second identification element is obtained to obtain the pulling distance.

[0111] In one specific embodiment, a mounting module is also provided, which is used to install the second identification element away from the outer wall of the server when the hard disk tray is pulled out of the server; the first identification element and the second identification element are located in the vertical direction of the same straight line.

[0112] In one specific embodiment, the programmable logic device in the timing module obtains the pull-out distance of the hard disk tray through the first and second identifiers; and uses a timer to calculate the pull-out time for the hard disk tray to meet the preset pull-out distance. Simultaneously, the programmable logic device communicates with the first and second identifiers through a general purpose input / output port to acquire data information from the first and second identifiers.

[0113] In one specific embodiment, the substrate management controller is communicatively connected to the programmable logic device; it accesses information on the programmable logic device via the integrated circuit bus, reads the extraction distance, and performs analysis in conjunction with a preset extraction distance.

[0114] In one specific embodiment, an alarm module is also included, which is used to switch the LED light from green to red and the buzzer to start an alarm when the hard drive tray is pulled out for more than a preset time.

[0115] For specific limitations regarding the hard drive tray position status monitoring system, please refer to the limitations of the hard drive tray position status monitoring method mentioned above, which will not be repeated here. Each module in the aforementioned hard drive tray position status monitoring system can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of the computer device in hardware form or independent of it, or they can be stored in the memory of the computer device in software form, so that the processor can call and execute the corresponding operations of each module.
