[0026] With the application of cloud services and big data, the amount of data has increased dramatically, so the demand for storage capacity in servers has continued to increase. In order to increase server storage capacity, on the one hand, hard disk manufacturers continue to increase the capacity of a single hard disk, and on the other hand, the number of hard disks supported by server systems is also increasing. In server systems, in order to facilitate monitoring of the status of hard disks, hard disk controllers are usually used to light up the status indicators connected to the hard disks. These status indicators can correspond to the read and write status, error status, and positioning status of the hard disk. However, with the increase in the number of hard disks, in high-density storage servers, the solution of introducing one or more indicators to indicate the status of a single hard disk will lead to complex server wiring, inconvenient management, and poor heat dissipation performance of the server system.

This application reduces the amount of wiring by setting one indicator light corresponding to multiple hard disks, and is beneficial to improving the heat dissipation performance of the system.

[0028] The technical solutions of the present application and the technical solutions of the present application are described in detail with specific embodiments below.

In the description of the present application, unless otherwise clearly specified and limited, each term should be understood in a broad sense in the art. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0029] Embodiment 1

[0030] Figure 1 A schematic diagram of the structure of a hard disk lighting device is shown in FIG. Figure 1 As shown, the device includes: a mainboard 01, a backplane 02, and an indicator light 03; the mainboard 01 includes a first hard disk connector 11 and a mainboard connector 12; the backplane 02 is connected to at least one hard disk 04, and the backplane 02 includes at least one second hard disk connector 21, and the hard disk 04 and the second hard disk connector 21 are connected one by one; the backplane 02 also includes a backplane processing module 22 and a backplane connector 23; wherein each indicator light 03 corresponds to a plurality of hard disks 04;

[0031] The first hard disk connector 11 is connected to the second hard disk connector 21; the mainboard 01 obtains the status signal of each hard disk 04 through the first hard disk connector 11, and sends the status signal of each hard disk 04 to the backplane connector 23 through the mainboard connector 12;

[0032] The input end of the backplane processing module 22 is connected to the backplane connector 23, and the output end of the backplane processing module 22 is connected to the indicator light 03 corresponding to the hard disk 04 connected to the backplane 02. The backplane processing module 22 is used to control the indicator light 03 corresponding to the hard disk 04 to light up when an abnormal state of any hard disk 04 connected to the backplane 02 is detected.

[0033] The type of the hard disk 04 in this example may be a mechanical hard disk (HDD, Hard Disk Drive) or a hybrid hard disk (HHD, Hybrid Hard Drive).

[0034] In actual application, the insertion position of the hard disk 04 in the server can be the front window or the rear window of the server, and the hard disk lighting device can be set on the front window or the rear window of the server accordingly. The backplane 02 is connected to at least one hard disk 04, wherein the backplane 02 can be connected to the hard disk 04 via a SATA interface type or a SAS interface type. The backplane 02 is also connected to the hard disk 04 in a one-to-one correspondence via the second hard disk connector 21 on the backplane 02. In addition, the motherboard 01 includes a first hard disk connector 11 and the first hard disk connector 11 is connected to the second hard disk connector 21. Therefore, the motherboard 01 can be connected to the hard disk 04 via the first hard disk connector 11, the second hard disk connector 21, to obtain the status signal of each hard disk 04, and send the status signal of each hard disk 04 to the backplane connector 23 via the motherboard connector 12.

[0035] Exemplarily, the interface type of the connection between the first hard disk connector 11 and the second hard disk connector 21 can also be a SATA interface or a SAS interface. In actual applications, the hard disk controller on the mainboard 01 obtains the signal of the hard disk 04, and reads the placeholder in the hard disk signal to obtain the status of the hard disk 04. Exemplarily, the "fault" or "0" placeholder can be pre-set to represent the abnormal state of the hard disk 04. After the mainboard 01 obtains the status signal of the hard disk 04, it is sent to the backplane processing module 22 through the mainboard connector 12 and the backplane connector 23. In actual applications, the mainboard 01 initiates an I / O request to the backplane processing module 22 through the HDD initiator, and outputs a data stream carrying the hard disk 04 status signal.

[0036] Exemplarily, the motherboard connector 12 and the backplane connector 23 can be connected via an SGPIO bus, so that the motherboard 01 sends an SGPIO data stream to the backplane processing module 22. The backplane processing module 22 is used to control the indicator light 03 corresponding to the hard disk 04 to light up when an abnormal state of any hard disk 04 connected to the backplane is detected.

[0037] Exemplarily, the backplane processing module 22 can be a complex programmable logic device or a microcontroller to achieve the function of decoding the data stream. In this example, each indicator light 03 corresponds to multiple hard disks 04. It can be understood that when two or more hard disks 04 are connected to a backplane 02, the backplane processing module 22 on the backplane 02 controls the connected indicator lights 03 so that the indicator lights 03 correspond to multiple hard disks 04.

[0038] Optionally, when there are two or more backplanes 02 and each backplane 02 is connected to a hard disk 04, the backplane processing module 22 on each backplane 02 can control the same indicator light 03 so that the indicator light 03 corresponds to multiple hard disks 04. It should be noted that the correspondence between the indicator light 03 and the hard disk 04 in actual application can be a combination of the above solutions.

[0039] The hard disk lighting device of this embodiment includes: a mainboard, a backplane, and an indicator light; the backplane is connected to at least one hard disk, and the backplane includes at least one second hard disk connector, and the hard disk and the second hard disk connector are connected one by one; the first hard disk connector on the mainboard is connected to the second hard disk connector; the mainboard obtains the status signal of each hard disk through the first hard disk connector, and sends the status signal of each hard disk to the backplane connector on the backplane through the mainboard connector on the mainboard; the input end of the backplane processing module on the backplane is connected to the backplane connector, and the output end of the backplane processing module is connected to the indicator light corresponding to the hard disk connected to the backplane, and the backplane processing module is used to control the indicator light corresponding to the hard disk to light up when an abnormal state of any hard disk connected to the backplane is detected. This application reduces the amount of wiring by setting multiple hard disks to correspond to one indicator light, and is conducive to improving the heat dissipation performance of the system.

[0040] As another example, Figure 2 A schematic diagram of the structure of a hard disk lighting device is shown in FIG. Figure 2 As shown, the backplane 02 further includes: a first switch 24;

[0041] One end of the first switch 24 is grounded, and the other end of the first switch 24 is connected to the indicator light 03 corresponding to the hard disk 04 connected to the backplane 02; the control end of the first switch 24 is connected to the backplane processing module 22, and is used to be turned on under the control of the backplane processing module 22 to light up the indicator light 03.

[0042] Exemplarily, the first switch 24 can be an open collector gate (OC gate) or an open drain gate (OD gate). When the first switch 24 is an OC gate, the emitter of the OC gate corresponds to one end of the first switch 24, the collector corresponds to the other end of the first switch 24, and the base corresponds to the control end; when the backplane processing module 22 controls the base-emitter voltage to be greater than the turn-on voltage, the OC gate is turned on to ground the indicator light 03 connected to the collector and light up. When the first switch 24 is an OD gate, the drain of the OD gate corresponds to one end of the first switch 24, the source corresponds to the other end of the first switch 24, and the gate corresponds to the control end; when the backplane processing module 22 controls the gate voltage to be greater than the threshold voltage, the OD gate is turned on to ground the indicator light 03 connected to the drain and light up.

[0043] Exemplarily, the output end of the backplane processing module 22 and the control end of the first switch 24 are connected via a GPIO bus. In the solution of this example, the backplane processing module can control the indicator light 03 to be grounded and lighted via the first switch.

[0044] As yet another example, the positive pole of the indicator light 03 is connected to the power source 25 , and the negative pole of the indicator light 03 is connected to the other end of the corresponding first switch 24 .

[0045] In this example, the power supply voltage of the indicator light 03 is provided by the power supply 25, forming a current path of the power supply 25, the positive electrode of the indicator light 03, the indicator light 03, the negative electrode of the indicator light 03, and the other end of the first switch 24; when the backplane processing module 22 controls the first switch 24 to be turned on, the indicator light 03 can be grounded through the other end of the first switch 24. In practical applications, the type of the indicator light 03 can be an LED lamp or a small fluorescent lamp. The solution of this example can provide a circuit structure for powering and turning on the indicator light.

[0046] As another example, Figure 3 Schematic diagram of the connection structure of a back panel and an indicator light is shown in FIG. Figure 3 As shown:

[0047] There are multiple backplanes 02 , and the backplane 02 includes a power supply 25 . The power supply 25 of the backplane 02 is connected to the positive pole of the indicator light 03 , and the other end of the first switch 24 is connected to the negative pole of the indicator light 03 .

[0048] like Figure 3 As shown, when there are two backplanes 02, each backplane 02 is integrated with a power supply 25, and the two power supplies 25 are uniformly connected to the positive pole of the indicator light 03, and the other ends of the first switches 24 corresponding to the two backplanes 02 are connected to the negative pole of the indicator light 03. Optionally, the power supply 25 can be integrated on only one of the backplanes 02 as the power supply 25 of the indicator light 03 to reduce wiring. The solution of this example can improve the stability of the power supply of the indicator light by setting multiple power supplies, and at the same time, multiple first switches are connected by wire-and mode, and the indicator light can be lit when any first switch is turned on.

[0049] As another example, the backplane 02 further includes a resistor 26 , the power supply 25 of the backplane 02 is connected to one end of the resistor 26 , and the other end of the resistor 26 is connected to the positive electrode of the indicator light 03 .

[0050] In this example, each backplane 02 further includes a resistor 26, and the power source 25 is connected to the positive electrode of the indicator light 03 through the resistor 26. In practical applications, one or more resistors 26 can be designed as needed to form a desired resistance value of the resistor 26. This solution can limit the current and prevent the indicator light from burning out by connecting a resistor.

[0051] As another example, Figure 4 exemplarily shows a schematic diagram of the structure of an indicator light. Figure 4 As shown, the indicator light 03 includes: a light emitting element 31 and a cable 32;

[0052] The first end of the cable 32 is connected to the light emitting element 31, and the second end of the cable 32 extends out of a forked structure to form a plurality of connector plugs 34, and the plurality of connector plugs 34 correspond to all the backplanes 02 one by one;

[0053] The backplane 02 also includes an indicator light connector 27, which includes a first pin and a second pin; the first pin is connected to the power supply 25 of the backplane 02, and the second pin is connected to the first switch 24; each connector plug 34 is connected to an indicator light connector 27 of the backplane 02 to connect the positive pole of the indicator light 03 to the power supply 25, and connect the negative pole of the indicator light 03 to the first switch 24.

[0054] In this example, the length of the indicator light 03 can be extended by the cable 32 , and the bifurcated structure can make the same indicator light 03 correspond to the status of the hard disks 04 on multiple backplanes 02 , thereby reducing the number of wiring.

[0055] Exemplarily, the connector plug 34 and the indicator light connector 27 of this example may be a cable-type plug and socket, and the number of cores of the cable 32 is selected according to actual needs.

[0056] Optionally, a label 35 may be attached to the cable 32 for easy identification, wherein the label 35 near the first end of the cable 32 may be used to identify the indicator light 03 , and the label 35 near the second end of the cable 32 may be used to identify the backplane 02 .

[0057] The solution of this example can improve the flexibility of connecting the indicator light and the backplane by means of a cable plug and a connector. In actual applications, the corresponding relationship between the backplane and the indicator light can be managed by plugging and unplugging.

[0058] As another example, Figure 4 As shown, the root of the bifurcated structure is covered by an insulating tape 33 .

[0059] Optionally, the insulating tape 33 may also be other types of coating materials that provide insulating protection functions, such as acetate cloth tape. The solution of this example can protect the cable by coating the root of the bifurcation structure of the cable with insulating tape, further improving the reliability of the cable.

[0060] As another example, the hard disks 04 connected to the same backplane 02 correspond to the same indicator light 03 .

[0061] The solution of this example, by setting the hard disks 04 connected to the same backplane 02 to correspond to the same indicator light 03, can use one indicator light 03 to monitor the status of all hard disks 04 connected to the backplane 02, reduce the amount of wiring, and facilitate subsequent troubleshooting of the hard disk status.

[0062] As another example, the mainboard 01 has multiple first hard disk connectors 11 , and the first hard disk connectors 11 are connected to the second hard disk connectors 21 in a one-to-one correspondence.

[0063] The solution of this example, by providing a plurality of first hard disk connectors 11 and connecting the first hard disk connectors 11 to the second hard disk connectors 21 one by one, can reduce the interference between different hard disk signals, improve the stability of data transmission, and also reduce the risk of circuit short circuit.

[0064] This embodiment also provides a server, comprising the hard disk lighting device in any embodiment.

[0065] The hard disk lighting device and server of the present embodiment include: a mainboard, a backplane, and an indicator light; the backplane is connected to at least one hard disk, and the backplane includes at least one second hard disk connector, and the hard disk and the second hard disk connector are connected one-to-one; the first hard disk connector on the mainboard is connected to the second hard disk connector; the mainboard obtains the status signal of each hard disk through the first hard disk connector, and sends the status signal of each hard disk to the backplane connector on the backplane through the mainboard connector on the mainboard; the input end of the backplane processing module on the backplane is connected to the backplane connector, and the output end of the backplane processing module is connected to the indicator light corresponding to the hard disk connected to the backplane, and the backplane processing module is used to control the indicator light corresponding to the hard disk to light up when an abnormal state of any hard disk connected to the backplane is detected. The present application reduces the amount of wiring and improves the heat dissipation performance of the hard disk system by setting multiple hard disks to correspond to one indicator light.

[0066] Embodiment 2

[0067] Embodiment 2 of this application combines Figure 5 The structural diagram of the hard disk lighting device is provided, and the following hard disk lighting process is provided:

[0068] like Figure 5 As shown, the motherboard 01 is connected to the hard disk 04 corresponding to the second hard disk connector on the backplane 02 through the first hard disk connector 11 and the second hard disk connector 21. The hard disk controller in the motherboard 01 obtains the status signal of each hard disk 04 through the link, and the HDD initiator in the motherboard 01 sends a signal to the backplane processing module 22 ( Figure 5 The backplane processing module 22 decodes the SGPIO data stream after receiving the SGPIO data stream, and obtains the status signal of the hard disk 04 connected to the backplane 02 to which the backplane processing module 22 belongs.

[0069] Correspondingly, if the status signal of any hard disk 04 is "Fault", the backplane processing module 22 pulls up the first switch 24 ( Figure 5 The internal processing logic of the backplane processing module 22 can be divided into two parts. The first part is to decode the SGPIO data stream to obtain the status signal corresponding to each hard disk 04, and the second part is to perform an "AND" logic process on the multiple status signals and send a high-level SPIO signal to the first switch 24. After receiving the high level, the control end of the first switch 24 turns on one end and the other end of the first switch 24, that is, Figure 5 The gate of the middle open-drain gate turns on the source and drain after receiving a high level.

[0070] On the other hand, indicator 03 ( Figure 5 The LED in the figure is connected to the indicator light connector 27 on the backplane 02 through a forked connector plug 34. The positive electrode of the indicator light 03 is connected through the first pin of the indicator light connector 27, and the negative electrode of the indicator light 03 is connected through the second pin of the indicator light connector 27. Furthermore, the first pin of the indicator light connector 27 is connected to the drain of the open drain gate; the second pin of the indicator light connector 27 is connected to VCC (power supply 25) through the resistor 26. Correspondingly, Figure 5 When the gate of the open-drain gate turns on the source and drain after receiving a high level, the LED is powered by VCC connected to the positive electrode and grounded through the drain connected to the negative electrode, thereby lighting up the LED.

[0071] The hard disk lighting device of this embodiment includes: a mainboard, a backplane, and an indicator light; the backplane is connected to at least one hard disk, and the backplane includes at least one second hard disk connector, and the hard disk and the second hard disk connector are connected one by one; the first hard disk connector on the mainboard is connected to the second hard disk connector; the mainboard obtains the status signal of each hard disk through the first hard disk connector, and sends the status signal of each hard disk to the backplane connector on the backplane through the mainboard connector on the mainboard; the input end of the backplane processing module on the backplane is connected to the backplane connector, and the output end of the backplane processing module is connected to the indicator light corresponding to the hard disk connected to the backplane, and the backplane processing module is used to control the indicator light corresponding to the hard disk to light up when an abnormal state of any hard disk connected to the backplane is detected. This application reduces the amount of wiring and improves the heat dissipation performance of the hard disk system by setting multiple hard disks to correspond to one indicator light.
