The motherboard 1 includes a processing unit 11 and a programmable logic unit 12 connected to the processing unit 11. The backplane 2 includes an expansion card unit 21 connected to the programmable logic unit 12. The hard disk unit 4 connects the processing unit 11 and the expansion card unit 21. The hard disk lamp unit 5 is connected to the expansion card unit 21 and controlled by the expansion card unit 21.
The communication bus unit 3 includes a plurality of communication buses 31, and the communication buses 31 are respectively used for connecting the processing unit 11 to the programmable logic unit 12 and connecting the programmable logic unit 12 to the expansion card unit 21. In the present embodiment, the communication bus 31 of the communication bus unit 3 is an Inter-Integrated Circuit (I2C) type, but not limited thereto.
The expansion card unit 21 is used for receiving a first status signal transmitted by the hard disk unit 4. The processing unit 11 will continuously transmit a status detection command to the hard disk unit 4 to detect the operation status of the hard disk unit 4 and receive a second status signal returned by the detected hard disk unit 4. The hard disk lamp unit 5 includes a first status lamp module 51 and a second status lamp module 52. The second status indicator module has a second status indicator 521 and a third status indicator 522.
When the hard disk unit 4 is in operation, the hard disk unit 4 transmits the first status signal to the expansion card unit 21, the programmable logic unit 12 actively receives the first status signal received by the expansion card unit 21, and the programmable logic unit 12 generates a corresponding first lighting message and transmits the first lighting message to the expansion card unit 21 after receiving the first status signal, and the expansion card unit 21 controls the first status indicator module 51 to light according to the first lighting message. In this embodiment, the expansion card unit 21 and the hard disk unit 4 perform information transmission in a General Purpose input/output (GPIO) manner, and the expansion card unit 21 and the hard disk indicator light unit 5 also perform information transmission in a GPIO manner, for example: the expansion card unit 21 is physically connected to the hard disk unit 4 and performs communication and data transmission through level Pull-Up (Pull Up) or Pull-Down (Pull Down) in a GPIO manner, and the expansion card unit 21 is also physically connected to the hard disk indicator unit 5 and controls the hard disk indicator unit 5 to light Up in a GPIO manner through level Pull-Up (Pull Up) or Pull-Down (Pull Down), but not limited thereto. The first status signal represents the status of Present and Active of the hard disk unit 4, but not limited thereto. In other words, when the hard disk unit 4 is powered on to operate, the on-position (Present) and Active (Active) operation states of the hard disk unit 4 are normal and continuously transmit the first status signal to the expansion card unit 21 to the programmable logic unit 12, the programmable logic unit 12 actively receives the first status signal received by the expansion card unit 21, and after receiving the first status signal, the programmable logic unit 12 generates the first lighting information and transmits the first lighting information to the expansion card unit 21. That is, the plc unit 12 can actively (Master) control and receive the information of the expansion card unit 21, and when the expansion card unit 21 receives the first lighting information transmitted by the plc unit 12, the first status indicator module 51 of the hard disk indicator unit 5 is controlled to light, so that the user can know the corresponding operating status of the hard disk unit 4 by lighting the first status indicator module 51. In the present embodiment, the programmable logic unit 12 is connected to the expansion card unit 21 by an integrated circuit communication bus (I2C), and in detail, the programmable logic unit 12 is equivalent to an I2C Master, and after an I2C command is sent to the expansion card unit 21 through an I2C port (not shown) of the programmable logic unit 12 and a first status signal information sent by the hard disk unit 4 received by the expansion card unit 21 is read, the programmable logic unit 12 sends the first lighting information (I2C command) to the expansion card unit 21, so that the expansion card unit 21 controls the lighting of the first status indicator light module 51 according to the first lighting information.
Then, the processing unit 11 transmits the status detection command to the hard disk unit 4 to detect the operating status of the hard disk unit 4, and the processing unit 11 receives the second status signal returned by the hard disk unit 4 and synchronously transmits the second status signal to the programmable logic unit 12, and the programmable logic unit 12 generates a corresponding second lighting message and transmits the second lighting message to the expansion card unit 21 after receiving the second status signal. In detail, during the operation of the hard disk unit 4, the processing unit 11 will transmit the state detection command to continuously detect the operation state of the hard disk unit 4, for example: position (Locate), normal (Normal), fail (Fail), and Alert (Alert), the hard disk unit 4 will send back the second status signal to the processing unit 11 after being detected, that is, the second status signal is the corresponding result after the hard disk unit 4 is detected. When the processing unit 11 receives the second status signal, it synchronously transmits the second status signal to the programmable logic unit 12, and the programmable logic unit 12 decodes the second status signal to generate the corresponding second lighting information and transmits the second lighting information to the expansion card unit 21. In this embodiment, the location (Locate), normal (Normal), fail (Fail), or Alert (Alert) states all have corresponding second lighting information, for example: the second status indicator 521 of the second status indicator module 52 is illuminated but the third status indicator 522 is not illuminated to indicate Fail, the second status indicator 521 is not illuminated but the third status indicator 522 is illuminated to indicate Alert, other operation states are not described in detail, but not limited thereto, and the second illumination information corresponding to each operation state of the hard disk unit 4 can be designed according to actual use requirements. In short, the programmable logic unit 12 decodes the received second status signal to generate the second lighting information corresponding to the detected result of the hard disk unit 4. When the expansion card unit 21 receives the second lighting information, the second status indicator 521 and the third status indicator 522 of the second status indicator module 52 are controlled to emit light according to the second lighting information.
The expansion card unit 21 can directly receive the first status signal transmitted by the hard disk unit 4 and receive the first lighting information and the second lighting information transmitted by the programmable logic unit 12 of the motherboard 1, and the expansion card unit 21 is matched to control the characteristics of the hard disk indicator unit 5, when the expansion card unit 21 receives the first lighting information, the first status indicator module 51 is controlled to emit light, so that the statuses of presence (Present) and activity (Active) of the hard disk unit 4 can be known conveniently. After the programmable logic unit 12 receives the second status signal, the corresponding second lighting information is generated and transmitted to the expansion card unit 21, and when the expansion card unit 21 receives the second lighting information, the second status indicator 521 and the third status indicator 522 of the second status indicator module 52 are controlled to illuminate according to the second lighting information, so that the user can know the location (Locate), the failure (Fail), the alarm (Alert), and other statuses of the hard disk unit 4. Moreover, by using the expansion card unit 21 and matching with the application concept of the programmable logic unit 12 originally arranged on the motherboard 1, the cost is effectively saved, the advantage that the programmable logic unit 12 does not need to be additionally arranged on the backboard 2 is achieved, the expansion card unit 21 has a small volume, the aperture ratio of the backboard 2 can be increased, the expansion card unit is convenient to arrange on the backboard 2, a complex arrangement design is not needed, and the production benefit is further improved. In the embodiment, the expansion card unit 21 is an I/O Expander, which can be 8-bit/16-bit, and the I/O Expander has the advantages of low cost and good versatility.
In addition, in the embodiment, the hard disk unit 4 is a solid state disk (not shown) having a plurality of Non-Volatile Memory (NVME) compliant standards, and the processing unit 11 and the hard disk unit 4 perform data transmission therebetween by using NVME signals, but not limited thereto, and the hard disk unit 4 may also be a solid state disk (not shown) using a plurality of SATA (Serial Advanced Technology Attachment) interfaces according to design requirements. It should be particularly noted that, if the hard disk unit 4 in SATA mode is used, referring to fig. 3 and fig. 4, the second embodiment of the control system for hard disk indicator lamp of server according to the present invention is substantially the same as the first embodiment of the control system for hard disk indicator lamp of server, except that: the processing unit 11 includes a Platform path Controller 111 (PCH) connected to the plc unit 12 and the hard disk unit 4, and a processor 112 connected to the Platform path Controller 111. In operation, the processor 112 of the processing unit 11 transmits the status detection command to the hard disk unit 4 via the platform path controller 111 to detect the operating status of the hard disk unit 4, and the hard disk unit 4 returns the second status signal to the platform path controller 111 after detection. The platform path controller 111 receives the second status signal transmitted by the hard disk unit 4 and synchronously transmits the second status signal to the programmable logic unit 12. In short, the processor 112 of the processing unit 11 communicates with the hard disk unit 4 in SATA mode through the platform path controller 111, and the platform path controller 111 receives the second status signal and synchronously transmits the second status signal to the programmable logic unit 12 for decoding. The plc unit 12 decodes the received second status signal, generates the second lighting information corresponding to the detected result of the hard disk unit 4, and transmits the second lighting information to the expansion card unit 21, and the expansion card unit 21 controls the second status indicator 521 and the third status indicator 522 of the second status indicator module 52 to light according to the second lighting information. It should be noted that, in the embodiment, only one communication bus 31 (I2C) is needed to connect the programmable logic unit 12 to the expansion card unit 21, and the programmable logic unit 12 is connected to the platform path controller 111 to perform information transmission in a Serial General Purpose input/output (SGPIO) manner, but not limited thereto. In other words, since the hard disk unit 4 is in the SATA state in this embodiment, the platform path controller 111 (PCH) communicates with the programmable logic unit 12 through a serial general purpose input/output (SGPIO) communication interface; in the first embodiment, the hard disk unit 4 is in NVME mode, so the processing unit 11 (CPU) communicates with the programmable logic unit 12 through the communication interface of the integrated circuit communication bus (I2C) and transmits data.
Referring to fig. 1 and fig. 2, a first embodiment of the method for controlling a server hard disk indicator lamp according to the present invention is applied to the first embodiment of the server hard disk indicator lamp control system. The control method of the server hard disk indicator lamp comprises a step (A), a step (B), a step (C) and a step (D).
First, in the step (a), when the hard disk unit 4 is in operation, a first status signal is transmitted to the expansion card unit 21, the programmable logic unit 12 actively receives the first status signal received by the expansion card unit 21, and after receiving the first status signal, the programmable logic unit 12 generates a corresponding first lighting message and transmits the first lighting message to the expansion card unit 21, and the expansion card unit 21 controls the first status indicator module 51 to light according to the first lighting message. In other words, when the hard disk unit 4 is in operation, the hard disk unit 4 transmits the first status signal to the expansion card unit 21, and when the expansion card unit 21 receives the first status signal, the first status indicator module 51 is controlled to emit light. In this embodiment, the expansion card unit 21 and the hard disk unit 4 perform information transmission in a General Purpose input/output (GPIO) manner, the expansion card unit 21 and the hard disk indicator light unit 5 also perform information transmission in a GPIO manner, and the first state signal is, but not limited to, a Present state and an Active state of the hard disk unit 4. In other words, when the hard disk unit 4 is powered on and operating, and the Present and Active operating states of the hard disk unit 4 are normal, the first status signal is continuously transmitted to the programmable logic unit 12 through the expansion card unit 21, and the programmable logic unit 12 generates the first lighting message and transmits the first lighting message to the expansion card unit 21 after receiving the first status signal. When the expansion card unit 21 receives the first lighting information, the first status indicator light module 51 of the hard disk indicator light unit 5 is controlled to light according to the first lighting information, so that the user can know the corresponding status of the hard disk unit 4 by lighting the first status indicator light module 51. In the present embodiment, the programmable logic unit 12 is connected to the expansion card unit 21 by an integrated circuit communication bus (I2C), and in detail, the programmable logic unit 12 is equivalent to an I2C Master, and after sending an I2C command to the expansion card unit 21 through an I2C port (not shown) of the programmable logic unit 12 and reading the first status signal information sent by the hard disk unit 4 received by the expansion card unit 21, the programmable logic unit 12 sends the first lighting information (I2C command) to the expansion card unit 21, so that the expansion card unit 21 controls the first status indicator module 51 to light according to the first lighting information.
Then, in the step (B), the processing unit 11 continuously transmits a status detection command to the hard disk unit 4 to detect the operation status of the hard disk unit 4, and the hard disk unit 4 returns the second status signal to the processing unit 11 after being detected. Specifically, during the operation of the hard disk unit 4, the processing unit 11 will transmit the state detection command to continuously detect the operation state of the hard disk unit 4, for example: position (Locate), normal (Normal), fail (Fail), and Alert (Alert), the hard disk unit 4 will send back the second status signal to the processing unit 11 after being detected, that is, the second status signal is the corresponding result after the hard disk unit 4 is detected.
Then, in the step (C), when the processing unit 11 receives the second status signal and synchronously transmits the second status signal to the programmable logic unit 12, and after the programmable logic unit 12 receives the second status signal, a corresponding second lighting message is generated and transmitted to the expansion card unit 21. Further, when the processing unit 11 receives the second status signal, it synchronously transmits the second status signal to the programmable logic unit 12, and the programmable logic unit 12 decodes the second status signal to generate the corresponding second lighting information and transmits the second lighting information to the expansion card unit 21. In this embodiment, the communication bus 31 (I2C) is used to connect the processing unit 11 to the programmable logic unit 12 and connect the programmable logic unit 12 to the expansion card unit 21, that is, in the step (C), the processing unit 11 transmits the second status signal to the programmable logic unit 12 through the corresponding communication bus 31 (I2C), and the programmable logic unit 12 decodes the received second status signal to generate the second lighting information and transmits the second lighting information to the expansion card unit 21 through the corresponding communication bus 31 (I2C).
Finally, in the step (D), when the expansion card unit 21 receives the second lighting information, the second status indicator 521 and the third status indicator 522 of the second status indicator module 52 are controlled to emit light according to the second lighting information. In this embodiment, the operation status of the hard disk unit 4 is as follows: the location (Locate), normal (Normal), fail (Fail) or alarm (Alert) states all have their corresponding second lighting information, for example: the second status indicator 521 of the second status indicator module 52 is illuminated but the third status indicator 522 is not illuminated to represent Fail, the second status indicator 521 is not illuminated but the third status indicator 522 is illuminated to represent Alert, other operation states are not described in detail, but not limited thereto, and the second illumination information corresponding to each operation state of the hard disk unit 4 can be designed according to actual use requirements. In the above step, briefly, in the step (B), the second status signal returned after the hard disk unit 4 is detected is a result corresponding to the hard disk unit 4, and in the step (C), after the programmable logic unit 12 decodes the received second status signal, the second lighting information corresponding to the result after the hard disk unit 4 is detected is generated and transmitted to the expansion card unit 21, and in the step (D), when the expansion card unit 21 receives the second lighting information, the second status indicator lamp 521 and the third status indicator lamp 522 of the second status indicator lamp module 52 are controlled to light according to the second lighting information.
The expansion card unit 21 can directly receive the first status signal transmitted by the hard disk unit 4 and receive the first lighting information and the second lighting information transmitted by the programmable logic unit 12 of the motherboard 1, and the expansion card unit 21 is matched to control the characteristics of the hard disk indicator unit 5, in the step (a), after receiving the first lighting information, the expansion card unit 21 controls the first status indicator module 51 to emit light, so that the statuses of presence (Present) and activity (Active) of the hard disk unit 4 can be known conveniently. In the step (C), after receiving the second status signal, the plc unit 12 decodes the second status signal and generates the corresponding second lighting information, and transmits the second lighting information to the expansion card unit 21. And in the step (D), when the expansion card unit 21 receives the second lighting information, the second status indicator module 52 and the third status indicator 522 are controlled to emit light according to the second lighting information, so that the user can know the location (Locate), failure (Fail), alarm (Alert) and other statuses of the hard disk unit 4.
