Description

Technical Field

[0002] The present invention relates to an indicator light control system, and particularly to a server hard disk indicator light control system and a control method thereof.

Background Art

[0004] In a server system, it is common to connect hard disk storage units to a backplane for data storage of the server system or other technical service applications and management requirements. In order to conveniently know and timely master whether there is an abnormality in the operation of the hard disk storage unit, the operation state of the hard disk storage unit is displayed through a hard disk status indicator light (LED). Generally speaking, in a server system, the hard disk status indicator lights are mostly arranged on the backplane and the light source is guided to a position visible to the user through a light guide column (such as a light pipe), for example, guiding the light source to the hard disk tray or directly guiding it to the hard disk storage unit, so that the user can directly see the lighting condition of the hard disk status indicator light and know the hard disk operation state. However, installing a light guide column not only increases the production cost, but also needs to consider the wiring position of the internal installation space, and the installation is complex and inconvenient. Although there is already a design of directly arranging the hard disk status indicator lights on the hard disk storage unit, generally speaking, only a small number of hard disk status indicator lights (LEDs) can be installed on the hard disk storage unit, and the hard disk status indicator lights only monotonously display the flashing or on / off state, and can only display several basic operation states of the hard disk storage unit, and it is necessary for practitioners to further think about and research improvement solutions.

Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a server hard disk indicator light control system that saves time and effort and effectively saves costs.

[0007] To solve the above technical problem, the server hard disk indicator light control system of the present invention includes a main board, a hard disk backplane module connected to the main board, a hard disk rack connected to the hard disk backplane module, and a hard disk installed on the hard disk rack and detachably coupled to the hard disk backplane module.

[0008] The main board includes a processing unit. The hard disk backplane module includes a programmable logic unit connected to the processing unit, a connection port connected to the processing unit, and a spring connector (POGO Pin) connected to the programmable logic unit and supporting hot plugging. The spring connector has four elastic contact pins. The four elastic contact pins of the spring connector are respectively a power pin (Power Pin), a ground pin (GND Pin), a data pin (SDA Pin), and a frequency pin (SCL Pin).

[0009] The hard disk rack includes a hard disk tray, a flexible circuit board unit disposed on the hard disk tray, a lighting driving unit connected to the flexible circuit board unit, and a plurality of hard disk indicators disposed on the hard disk tray and controlled by the lighting driving unit to emit light. The flexible circuit board unit has a metal contact piece that is connected to the lighting driving unit and detachably coupled to the spring connector. The metal contact piece has four pressing members corresponding to the elastic contact pins.

[0010] The hard disk is installed on the hard disk tray of the hard disk rack and detachably coupled to the connection port of the hard disk backplane module.

[0011] When the hard disk is inserted and coupled to the connection port of the hard disk backplane module, the pressing members of the metal contact piece of the hard disk rack press against the elastic contact pins of the hard disk backplane module to form an electrical connection. The processing unit of the main board transmits a status detection instruction through the connection port to the hard disk to detect the operating status of the hard disk and receives a status signal returned by the hard disk after being detected.

[0012] When the hard disk is operating, when the processing unit receives the status signal transmitted by the hard disk through the connection port and synchronously transmits it to the programmable logic unit, after the programmable logic unit receives the status signal, it generates a corresponding lighting message and transmits it to the spring connector, and the data pin and the frequency pin of the spring connector pass through the corresponding pressing member of the metal contact piece to the lighting driving unit. When the lighting driving unit receives the lighting message, it controls the hard disk indicators to emit light according to the lighting message.

[0013] Another technical problem to be solved by the present invention is to provide a control method for a server hard disk indicator that saves time and effort and effectively saves costs.

[0014] To solve the above-mentioned another technical problem, the control method of the server hard disk indicator of the present invention is applied to the above-mentioned server hard disk indicator control system. The control method of the server hard disk indicator includes a step (A), a step (B), a step (C), and a step (D).

[0015] In the step (A), when the hard disk is operating, the processing unit transmits a status detection instruction through the connection port to the hard disk to detect the operating status of the hard disk.

[0016] In the step (B), the processing unit receives a status signal returned by the hard disk after being detected through the connection port and synchronously transmits it to the programmable logic unit.

[0017] In this step (C), after receiving the status signal, the programmable logic unit generates a corresponding lighting message and transmits it to the spring connector. The data pin (SDA Pin) and the frequency pin (SCL Pin) of the spring connector pass through the corresponding pressing parts of the metal contact piece to the lighting driving unit.

[0018] In this step (D), when the lighting driving unit receives the lighting message, it controls the hard disk indicator light to emit light according to the lighting message.

[0019] Compared with the prior art, in the present invention, the metal contact piece of the flexible circuit board unit of the hard disk rack is detachably combined with the spring connector of the hard disk backplane module, and the hard disk is detachably combined with the connection port of the hard disk backplane module. With the application that the hard disk rack has the hard disk indicator light, when the hard disk is inserted and combined with the connection port of the hard disk backplane module, the pressing parts of the metal contact piece of the hard disk rack press against the elastic contact pins of the spring connector to form an electrical connection. When the processing unit receives the status signal of the hard disk through the connection port and transmits it to the programmable logic unit, the programmable logic unit generates a lighting message corresponding to the status signal, passes through the spring connector and the metal contact piece, and reaches the lighting driving unit. The lighting driving unit controls the hard disk indicator light to emit light according to the lighting message. The assembly is simple and there is no need to install a light guide separately, saving time, effort and effectively reducing costs.

Detailed Embodiment

[0029] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0030] Refer to Figure 1 and Figure 2 , an embodiment of the server hard disk indicator control system of the present invention includes a main board 1, a hard disk backplane module 2 connected to the main board 1, a hard disk rack 3 connected to the hard disk backplane module 2, and a hard disk 4 installed on the hard disk rack 3 and detachably coupled to the hard disk backplane module 2.

[0031] The main board 1 includes a processing unit 11. The hard disk backplane module 2 includes a programmable logic unit 21 connected to the processing unit 11, a connection port 22 connected to the processing unit 11, and a spring connector 23 connected to the programmable logic unit 21 and supporting hot plugging. The spring connector 23 has four elastic contact pins 24. In this embodiment, the processing unit 11 is in the form of an expander, for example, a Raid card (expansion card), but not limited thereto. According to actual usage requirements, the processing unit 11 can also be in the form of a CPU or other forms.

[0032] The hard disk rack 3 includes a hard disk tray 31, a flexible circuit board unit 32 disposed on the hard disk tray 31, a lighting driving unit 33 connected to the flexible circuit board unit 32, and a plurality of hard disk indicators 34 disposed on the hard disk tray 31 and controlled by the lighting driving unit 33 to emit light. The flexible circuit board unit 32 has a metal contact piece 321 connected to the lighting driving unit 33 and detachably coupled to the spring connector 23. The metal contact piece 321 has four pressing members 322 corresponding to the elastic contact pins 24.

[0033] The hard disk 4 is installed on the hard disk tray 31 of the hard disk rack 3 and detachably coupled to the connection port 22 of the hard disk backplane module 2. When the hard disk 4 is inserted and coupled to the connection port 22 of the hard disk backplane module 2, the pressing member 322 of the metal contact piece 321 of the hard disk rack 3 presses against the elastic contact pins 24 of the hard disk backplane module 2, forming an electrical connection. The processing unit 11 of the main board 1 transmits a status detection instruction through the connection port 22 to the hard disk 4 to detect the operating status of the hard disk 4 and receives a status signal returned after the hard disk 4 is detected. In this embodiment, the connection port 22 is in the form of an SF8639 connection port, but is not limited thereto.

[0034] When the hard disk 4 is operating, the processing unit 11 receives the status signal transmitted by the hard disk 4 through the connection port 22 and synchronously transmits it to the programmable logic unit 21. After receiving the status signal, the programmable logic unit 21 generates a corresponding lighting message and transmits it to the spring connector 23, through the metal contact piece 321, and then to the lighting driving unit 33. When the lighting driving unit 33 receives the lighting message, it controls the hard disk indicator light 34 to emit light according to the lighting message.

[0035] During assembly, the hard disk 4 is inserted and coupled to the connection port 22 of the hard disk backplane module 2, and the pressing member 322 of the metal contact piece 321 of the hard disk rack 3 presses against the elastic contact pins 24 of the hard disk backplane module 2, forming an electrical connection. That is to say, since the hard disk 4 is installed in the hard disk rack 3, when the hard disk 4 is inserted and coupled to the connection port 22 of the hard disk backplane module 2, the metal contact piece 321 of the hard disk rack 3 directly presses against the spring connector 23 of the hard disk backplane module 2, and the pressing member 322 of the metal contact piece 321 directly presses against the elastic contact pins 24 of the spring connector 23, forming an electrical connection. At this time, the assembly operation of the hard disk rack 3 and the hard disk 4 coupled to the hard disk backplane module 2 is completed. It should be noted that, in this embodiment, the spring connector 23 further has a hot-swap unit 25. The hot-swap unit 25 is connected to the elastic contact pins 24, enabling the pressing member 322 of the metal contact piece 321 of the hard disk rack 3 to be hot-pluggably coupled to the elastic contact pins 24 of the hard disk backplane module 2. That is to say, the spring connector 23 enables the elastic contact pins 24 to support the pressing member 322 of the metal contact piece 321 of the hard disk rack 3 to perform a hot-insertion action through the hot-swap unit 25.

[0036] When the hard disk 4 is operating, the processing unit 11 of the main board 1 will transmit the status detection instruction through the port 22 to the hard disk 4 to detect the operating status of the hard disk 4, such as: Locate, Normal, Present, Active, Fail, and Alert, etc. The processing unit 11 receives the status signal transmitted by the hard disk 4 through the port 22 and synchronously transmits it to the programmable logic unit 21. After the programmable logic unit 21 receives the status signal, it will generate a corresponding lighting message according to the content of the status signal and transmit it to the spring connector 23, through the metal contact piece 321, and then to the lighting driving unit 33. When the lighting driving unit 33 receives the lighting message, it will control the hard disk indicator 34 to emit light according to the lighting message. In other words, after the programmable logic unit 21 receives the status signal transmitted by the processing unit 11 and determines the current operating status of the hard disk 4, it generates a corresponding lighting message. Then, the programmable logic unit 21 transmits the lighting message through the spring connector 23, through the metal contact piece 321, and then to the lighting driving unit 33, so that the lighting driving unit 33 controls the hard disk indicator 34 to emit light according to the lighting message. In this embodiment, the programmable logic unit 21 is in the form of a Complex Programmable Logic Device (CPLD), but not limited thereto, and it can also be in the form of a Field Programmable Gate Array (FPGA).

[0037] Here, it should be noted that the embodiment of the server hard disk indicator control system of the present invention further includes a communication bus unit 5. The communication bus unit 5 includes a plurality of communication buses 51, and the communication buses 51 are respectively used to connect the processing unit 11 to the programmable logic unit 21 and to connect the programmable logic unit 21 to the spring connector 23. In this embodiment, the communication bus 51 is in the form of an Inter-Integrated Circuit (I²C) communication bus 51. When the programmable logic unit 21 issues the lighting message, it is transmitted through the integrated circuit communication bus 51 to the spring connector 23, transmitted to the metal contact piece 321, and then to the lighting driving unit 33, but not limited thereto, and the communication bus 51 can also be in the form of I3C.

[0038] With the design that the metal contact piece 321 of the flexible circuit board unit 32 of the hard disk rack 3 is detachably combined with the spring connector 23 of the hard disk backplane module 2, and in cooperation with the application that the hard disk 4 is detachably combined with the connection port 22 of the hard disk backplane module 2, when the hard disk 4 is inserted and combined with the connection port 22 of the hard disk backplane module 2, the pressing member 322 of the metal contact piece 321 of the hard disk rack 3 will press against the elastic contact pin 24 of the spring connector 23 and form an electrical connection. When the processing unit 11 receives the status signal of the hard disk 4 through the connection port 22 and transmits it to the programmable logic unit 21, the programmable logic unit 21 will generate a lighting message corresponding to the status signal and pass through the spring connector 23 and the metal contact piece 321, and then reach the lighting driving unit 33, and the lighting driving unit 33 will control the hard disk indicator light 34 to emit light according to the lighting message. The assembly is simple and there is no need to install a light guide separately, saving time, effort and effectively reducing costs.

[0039] It should be specifically noted that, in this embodiment, the four elastic contact pins 24 of the spring connector 23 are respectively a power pin, a ground pin, a data pin (SDA Pin), and a frequency pin (SCL Pin) (the pins of the elastic contact pins 24 are not defined and marked in the figure). When the pressing member 322 of the metal contact piece 321 presses against the elastic contact pins 24 of the hard disk backplane module 2 to form an electrical connection, and when the programmable logic unit 21 receives the status signal, it will generate a corresponding lighting message, and the data pin (SDA Pin) and frequency pin (SCL Pin) of the spring connector 23 will transmit the message to the lighting driving unit 33 through the corresponding pressing member 322 of the metal contact piece 321. Then, the lighting driving unit 33 controls the hard disk indicator 34 to emit light according to the received lighting message. Specifically, in this embodiment, the programmable logic unit 21 communicates with the lighting driving unit 33 by transmitting the lighting message (I²C command) through the data pin (SDA Pin) and frequency pin (SCL Pin) of the spring connector 23 in the I²C transmission mode. That is to say, the programmable logic unit 21 sends out the lighting message (I²C command) through an I²C port (not shown in the figure), transmits it to the spring connector 23 through the integrated circuit communication bus 51, and the data pin (SDA Pin) and frequency pin (SCL Pin) of the spring connector 23 transmit the message through the metal contact piece 321 to the lighting driving unit 33, so that the lighting driving unit 33 controls the hard disk indicator 34 to emit light according to the received lighting message. In other words, in this embodiment, due to the design of the lighting driving unit 33 of the hard disk rack 3, the programmable logic unit 21 can communicate with the lighting driving unit 33 through the data pin (SDA Pin) and frequency pin (SCL Pin) of the spring connector 23 in the I²C transmission mode, and the lighting driving unit 33 controls the hard disk indicator 34 to emit light to present a variety of lighting combinations. Incidentally, in this embodiment, the spring connector 23 is in the form of a POGO Pin connector (see Figure 5 and Figure 6 ), but this is not limiting. Compared with using traditional connector forms, the POGO Pin connector is lightweight, small in size, reduces the occupied space, and has low cost. In addition, the elastic contact pins 24 of the POGO Pin connector have accurate and stable upper contacts, a larger compression amount, and a small spring pressure change, etc.

[0040] In addition, in this embodiment, the lighting driving unit 33 is in the form of an LED Driver, and the lighting driving unit 33 controls the lighting, extinguishing, light emitting brightness, and blinking rate of each hard disk indicator light 34 by pulling up or pulling down the level. Therefore, the lighting driving unit 33 can control the hard disk indicator lights 34 to present various different lighting combinations in cooperation. In this embodiment, the hard disk indicator lights 34 are arranged on the hard disk tray 31 of the hard disk rack 3 in a geometric shape, such as circular, square, triangular and other geometric plane shapes, and the lighting driving unit 33 can control the hard disk indicator lights 34 to present lighting combinations that light up in a clockwise order and lighting combinations that light up in a counterclockwise order in cooperation. For example, the hard disk indicator lights 34 are arranged in a circular pattern (see Figure 3 ), the lighting driving unit 33 can control the hard disk indicator lights 34 to present a lighting combination of clockwise dynamic rotation that lights up in a clockwise order and a lighting combination of counterclockwise dynamic rotation that lights up in a counterclockwise order, but not limited thereto. It can also be a lighting combination of a square arrangement (see Figure 4 ) or other graphic arrangements, and diverse lighting combinations of the hard disk indicator lights 34 can be achieved according to different customized design requirements. In this embodiment, when the hard disk indicator lights 34 present a lighting combination of clockwise dynamic rotation that lights up in a clockwise order, it represents that the operating state of the hard disk 4 is normal, and when the hard disk indicator lights 34 present a lighting combination of counterclockwise dynamic rotation that lights up in a counterclockwise order, it represents that the operating state of the hard disk 4 is abnormal and failed, but not limited thereto. Lighting combinations corresponding to each operating state of the hard disk 4 can be designed according to actual design requirements.

[0041] Refer to Figure 1 and Figure 2 , for an embodiment of the control method of the server hard disk indicator light of the present invention, which is applied to the embodiment of the above server hard disk indicator light control system. The control method of the server hard disk indicator light includes a step (A), a step (B), a step (C), and a step (D).

[0042] First, in step (A), when the hard disk 4 operates, the processing unit 11 transmits a status detection instruction through the port 22 to the hard disk 4 to detect the operating status of the hard disk 4. And in step (B), the processing unit 11 receives a status signal returned after the hard disk 4 is detected through the port 22 and synchronously transmits it to the programmable logic unit 21. Simply put, when the hard disk 4 operates, the processing unit 11 of the main board 1 will transmit the status detection instruction to the hard disk 4 to detect the operating status of the hard disk 4, such as: Locate, Normal, Present, Active, Fail, and Alert, etc. operating statuses, and the processing unit 11 receives the status signal transmitted by the hard disk 4 through the port 22 and synchronously transmits it to the programmable logic unit 21. In this embodiment, the port 22 is in the form of an SF8639 port, but it is not limited thereto.

[0043] Next, in step (C), after receiving the status signal, the programmable logic unit 21 will generate a corresponding lighting message and transmit it to the spring connector 23, through the metal contact 321, and to the lighting driving unit 33. Finally, in step (D), when the lighting driving unit 33 receives the lighting message, it will control the hard disk indicator 34 to emit light according to the lighting message. In other words, after the programmable logic unit 21 receives the status signal transmitted by the processing unit 11 and determines the current operating status of the hard disk 4 and generates a corresponding lighting message, the programmable logic unit 21 transmits the lighting message through the spring connector 23 through the metal contact 321 and to the lighting driving unit 33, so that the lighting driving unit 33 controls the hard disk indicator 34 to emit light according to the lighting message. In this embodiment, the programmable logic unit 21 is in the form of a Complex Programmable Logic Device (CPLD), but it is not limited thereto, and it can also be in the form of a Field Programmable Gate Array (FPGA).

[0044] By means of the design that the metal contact piece 321 of the flexible circuit board unit 32 of the hard disk holder 3 is detachably combined with the spring connector 23 of the hard disk backplane module 2, and in cooperation with the application that the hard disk 4 is detachably combined with the connection port 22 of the hard disk backplane module 2, when the hard disk 4 is inserted and combined with the connection port 22 of the hard disk backplane module 2, the pressing member 322 of the metal contact piece 321 of the hard disk holder 3 will press against the elastic contact pin 24 of the spring connector 23 and form an electrical connection. In step (B), when the processing unit 11 receives the status signal of the hard disk 4 through the connection port 22 and transmits it to the programmable logic unit 21, and in step (C), the programmable logic unit 21 will generate a lighting message corresponding to the status signal and pass it through the spring connector 23 and the metal contact piece 321, and then to the lighting driving unit 33. In step (D), the lighting driving unit 33 will control the hard disk indicator light 34 to emit light according to the lighting message. The assembly is simple and there is no need to install a light guide separately, which saves time, effort and effectively reduces costs.

[0045] It should be particularly noted that in this embodiment, the four elastic contact pins 24 of the spring connector 23 are respectively a power pin (Power Pin), a ground pin (GND Pin), a data pin (SDA Pin), and a frequency pin (SCL Pin). In step (C), when the programmable logic unit 21 receives the status signal, it will generate the corresponding lighting message and pass it from the data pin (SDA Pin) and the frequency pin (SCL Pin) of the spring connector 23 through the corresponding pressing member 322 of the metal contact piece 321 to the lighting driving unit 33. In step (D), the lighting driving unit 33 will control the hard disk indicator light 34 to emit light according to the received lighting message. Specifically, in this embodiment, the programmable logic unit 21 communicates the lighting message (I²C command) to the lighting driving unit 33 through the data pin (SDAPin) and the frequency pin (SCL Pin) of the spring connector 23 in the I²C transmission mode. That is to say, the programmable logic unit 21 issues the lighting message (I²C command) through an I²C port (not shown in the figure) and transmits it to the spring connector 23 via the integrated circuit communication bus 51, and passes through the data pin (SDA Pin) and the frequency pin (SCL Pin) of the spring connector 23 through the metal contact piece 321, and then to the lighting driving unit 33, so that the lighting driving unit 33 controls the hard disk indicator light 34 to emit light according to the received lighting message.

[0046] In addition, in this embodiment, the lighting driving unit 33 is in the form of an LED Driver, and the lighting driving unit 33 controls the lighting, extinguishing, light brightness and flashing rate of each hard disk indicator light 34 by pulling up or pulling down the level, so the lighting driving unit 33 can control the hard disk indicator lights 34 to cooperate and present a variety of different light combinations, and the hard disk indicator lights 34 are arranged on the hard disk tray 31 and are arranged in a geometric shape. In the step (D), the lighting driving unit 33 controls the hard disk indicator lights 34 to light according to the lighting message received, and the lighting driving unit 33 can control the hard disk indicator lights 34 to cooperate and present a light combination of clockwise and counterclockwise light combinations. Further, in this embodiment, the hard disk indicator light 34 is disposed on the hard disk tray 31 of the hard disk rack 3 and is arranged in the shape of a geometric figure, such as a circle, square, triangle or other geometric plane figure arrangement, and the light driving unit 33 can control the hard disk indicator light 34 to cooperate with each other to present a clockwise and counterclockwise light combination. For example, the hard disk indicator light 34 is arranged in a circle, and the light driving unit 33 can control the hard disk indicator light 34 to present a clockwise and dynamically rotating light combination, and a counterclockwise and dynamically rotating light combination, but it is not limited to this, and it can also be a light combination arranged in other figures, and the hard disk indicator light 34 can present a variety of light combinations according to different customized design requirements. In addition, in the present embodiment, when the hard disk indicator light 34 presents a clockwise dynamically rotating light combination that lights up in sequence, it represents that the operating state of the hard disk 4 is normal (Normal); when the hard disk indicator light 34 presents a counterclockwise dynamically rotating light combination that lights up in sequence, it represents that the operating state of the hard disk 4 is abnormal and failed (Fail), but this is not limited to this, and the light combination corresponding to each operating state of the hard disk 4 can be designed according to actual design requirements.

[0047] In summary, for the server hard disk indicator control system and its control method of the present invention, through the design that the metal contact piece 321 of the hard disk rack 3 is detachably combined with the spring connector 23 of the hard disk backplane module 2 and the hard disk 4 is detachably combined with the connection port 22 of the hard disk backplane module 2, and in cooperation with the application that the hard disk rack 3 is provided with the hard disk indicator 34, when the hard disk 4 is inserted and combined with the hard disk backplane module 2, the metal contact piece 321 of the hard disk rack 3 will press against the elastic contact pins 24 of the spring connector 23 and form an electrical connection. When the processing unit 11 receives the status signal of the operation of the hard disk 4 and transmits it to the programmable logic unit 21, the programmable logic unit 21 will generate a corresponding lighting message and transmit it through the spring connector 23 and the metal contact piece 321 to the lighting driving unit 33, and the lighting driving unit 33 will control the hard disk indicator 34 to emit light according to the lighting message. The assembly is simple and there is no need to additionally install an optical duct, which saves time, effort and effectively reduces costs.
