Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.

The hard disk lighting method provided by the embodiment of the application can be applied to an application scene of replacing the hard disk according to the hard disk indicator lamp. For example, when a certain hard disk in the server hard disk backplane fails, the failed hard disk is usually pulled out and replaced with a new hard disk. In order to enable a user to quickly and accurately know the type of the hard disk to be replaced in the slot position, the hard disk indicator lamp of the corresponding hard disk type still needs to be turned on after the hard disk is pulled out, and the user can determine the type of the hard disk to be inserted in the slot position through the hard disk indicator lamp and replace the hard disk. And further, the efficiency and the accuracy of replacing the hard disk are improved.
At present, after a hard disk in a slot of a server backplane is pulled out, a Complex Programmable Logic Device (CPLD) in the server backplane cannot continuously determine the type of the hard disk in the slot, so that a target signal corresponding to the type of the hard disk cannot be output and state information of the hard disk cannot be analyzed, and then a state indicator lamp of the corresponding hard disk cannot be turned on according to the state information of the hard disk. When a user needs to re-insert a new hard disk into the slot, the user cannot practicably insert the hard disk because the type of the hard disk cannot be accurately confirmed, and the efficiency of replacing the hard disk is low. In addition, if a wrong hard disk is inserted, data storage failure or data loss is easily caused, so that unnecessary loss is brought to a user, and extremely poor user experience is caused, namely the accuracy of hard disk replacement is low.
In view of the above problems, an embodiment of the present application provides a hard disk lighting method, which may latch hard disk state information at a previous time when a hard disk is pulled out, so as to light a hard disk indicator corresponding to a type of the hard disk according to the hard disk state information at the previous time. The function that the hard disk indicator lamp of the corresponding hard disk type can be turned on after the hard disk is pulled out is achieved, a user is helped to quickly and accurately master the state of the hard disk in the slot, the efficiency of hard disk replacement can be improved, the phenomenon that data is lost or data storage fails due to the fact that the type of the replaced hard disk is wrong can be avoided, and then the efficiency and the accuracy of the user in replacing the hard disk are improved.
Fig. 1 is a system architecture diagram of a hard disk lighting method according to an embodiment of the present invention, as shown in fig. 1, the system includes a hard disk 10 and a server backplane 11. The hard disk 10 includes a hard disk interface 101, and the server backplane 11 includes a hard disk connector 110, a CPLD111, and a hard disk indicator 112. The hard disk interface 101 of the hard disk 10 is connected to the CPLD111 through the hard disk connector 110, and the CPLD111 can determine the type of the connected hard disk 10, analyze the state information corresponding to the connected hard disk 10, and turn on the hard disk indicator 112. The hard disk 10 may be a SATA/SAS type hard disk or an NVME type hard disk.
It should be understood that the number of the hard disk 10, the server backplane 11, the hard disk connector 110, the CPLD111 and the hard disk indicator light 112 in the system architecture diagram shown in fig. 1 is only exemplary, and a greater or lesser number falls within the scope of the present application.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart illustrating a hard disk lighting method according to an embodiment of the present disclosure, where the hard disk lighting method may be implemented by any device that executes the hard disk lighting method, and the device may be implemented by software and/or hardware. In this embodiment, the device may be integrated in the CPLD111 as shown in fig. 1. As shown in fig. 2, a hard disk lighting method provided in the embodiment of the present application includes the following steps:
step 201: when the slot position of the backboard of the server is detected to be pulled out of the hard disk, the state information of the hard disk is determined through a target signal corresponding to the previous moment when the slot position is pulled out of the hard disk, wherein the target signal comprises an SGPIO signal or a VPP signal.
When the hard disk is inserted into the slot position, the CPLD needs to determine the type of the hard disk, selectively outputs a target signal according to the type of the hard disk, where the target signal includes a Serial General Purpose Input/Output (SGPIO) signal or a Virtual Port (VPP) signal, and finally analyzes the state information corresponding to the hard disk in the slot position in the target signal. The state information of the hard disk refers to the state of the hard disk in the server backboard. For example: location information (Locate), Error information (Error), Active information (Active), Error information (Fault), and other information.
Specifically, whether the hard disk is inserted into the slot position is detected by detecting a signal of a first pin of the slot position, and if the signal of the first pin is a low level signal, it is determined that the hard disk is inserted into the slot position.
The signal of the first PIN is a signal PIN4(IFDET #) for determining whether the hard disk is inserted into the slot. And when the signal of the first pin is at a high level, determining that the hard disk is pulled out of the slot position, and when the signal of the first pin is at a low level, determining that the hard disk is inserted into the slot position. For example, when a hard disk is not inserted into a slot of a server backplane, the first pin signal is at a high level, and when an NVME or SATA hard disk is inserted at this time, the first pin signal changes to a low level.
In this example, whether the hard disk is inserted into the slot of the server backplane can be detected through the state change of the signal level of the first pin, so that the efficiency of determining whether the hard disk is in the slot can be improved.
For example, when it is detected that the hard disk is inserted into the slot, i.e., the signal of the first pin is low, the type of the hard disk needs to be determined first. In order to determine the type of the hard disk inserted into the slot position, a signal of a second pin of the slot position needs to be acquired at the same time, and if the signal of the second pin is a low-level signal, the type of the hard disk is determined to be SAS or SATA; and if the signal of the second pin is a high level signal, determining the type of the hard disk to be NVME. The signal of the second PIN is a signal PIN10(PRSNT #) for determining the type of the hard disk.
In order to better understand whether the hard disk is inserted into the slot and determine the process of inserting the hard disk type, table 1 below shows the corresponding relationship between the values of PIN4 and PIN10 and whether the hard disk is inserted into the slot and the hard disk type.
TABLE 1
| Signal of the second pin | Signal of the first pin | |
| SATA/SAS hard disk | Is low in | Is low in |
| NVME hard disk | Height of | Is low in |
As can be seen from table 1, the level change state of the first pin signal of the slot position can determine whether the hard disk is inserted into the slot position, and if the signal of the first pin is at a low level, it indicates that the hard disk is inserted; if the level is high, no hard disk is inserted. When the hard disk inserted into the slot position is detected, the type of the hard disk inserted into the slot position can be judged according to the signal level change state of a second pin of the slot position, and if the signal of the second pin is low level, the type of the inserted hard disk is an SATA (serial advanced technology attachment) or SAS (serial attached small computer system interface) hard disk; if the level is high, the type of the inserted hard disk is NVME hard disk.
In the mode, the state of inserting or extracting the hard disk in the slot position and the automatic identification process of the type of the hard disk are determined by the combined judgment of the first pin signal and the second pin signal, so that the type of the hard disk inserted in the slot position can be simply and quickly determined, and the efficiency and the accuracy of determining the type of the hard disk are improved.
Illustratively, after the type of the hard disk inserted into the slot position is determined, a target signal can be selectively output according to the type of the hard disk, and if the type of the hard disk is SAS or SATA, the target signal is determined to be an SGPIO signal; and if the type of the hard disk is NVME, determining that the target signal is a VPP signal.
Specifically, the hard disk type can be automatically identified according to a first pin signal and a second pin signal of a slot position of the server backplane, and then a target signal is selectively output. Wherein the selective output of the target signal needs to be realized by using a hardware circuit of the CPLD in the backplane, for example: a Multiplexer (MUX), which is a combined circuit, is an electronic switch, and can select one input signal from a plurality of input signals as an output signal, for example: the input signal has A, B two signals, and the output signal passing through the multiplexer is the A signal or the B signal. The CPLD can select a target signal corresponding to the type of the hard disk to pass through according to the type of the hard disk inserted.
FIG. 3 is a diagram illustrating selective output of target signals according to types of hard disks. As shown in fig. 3, the server includes a motherboard 301 and a backplane 302, where the motherboard 301 includes a Central Processing Unit (CPU) 303 and a Platform Controller Hub (PCH)/RAID card/Host Bus Adapter card (HBA) 304, and the backplane includes a CPLD305, a slot 306, and a hard disk indicator 307. The circulation of the VPP signal is realized by the CPU303 in the mainboard 301 and the CPLD305 in the backboard 302 through the directly connected I2C HEADER; meanwhile, the PCH/RAID card/HBA card 304 in the mainboard 301 and the CPLD305 in the backboard 302 realize the circulation of the SGPIO signal through the SGPIO HEADER. The CPLD305 may determine an output target signal according to the type of the hard disk inserted in the slot 306, and control the hard disk indicator 307 to light up according to the target signal. For example: two input signals of the CPLD are a VPP signal and an SPGIO signal respectively, wherein the VPP signal is obtained through I2C directly connected with the CPU, and the SPGIO signal is obtained through a PCH/RAID card/HBA card. When the type of the hard disk inserted into the slot is NVME, the CPLD selects the VPP signal as an output signal according to the inserted NVME hard disk so as to light a hard disk indicator lamp corresponding to the NVME type hard disk. When the type of the hard disk inserted into the slot position is SAS or SATA, the CPLD selects the SPGIO signal as an output signal according to the inserted SAS or SATA hard disk to light a hard disk indicator lamp corresponding to the SAS or SATA hard disk.
In the method, the CPLD determines the output target signal according to the type of the hard disk inserted into the slot, and the output target signal can be analyzed to the state information of the hard disk in the slot, so that the target signal selectively switched and output by the hard disk under the condition of mixed insertion is realized.
And when the signal of the first pin of the detection slot is changed from low level to high level, the hard disk in the slot of the server backplane is determined to be pulled out. Because the hard disk does not exist in the slot position, the CPLD cannot acquire the type of the hard disk, and therefore the target signal cannot be output any more. In order to ensure that the target signal can be output to determine the state information of the hard disk after the hard disk is pulled out, the state information of the hard disk can be determined by the target signal corresponding to the previous moment when the hard disk is pulled out of the slot position.
Step 202: and according to the state information of the hard disk, lighting up the hard disk indicator lamp corresponding to the type of the hard disk.
The state information of the hard disk refers to the state of the hard disk in the slot position of the server backplane. For example: location information (Locate), Error information (Error), Active information (Active), Error information (Fault), and other information. Because the activity information frequencies of the hard disks of different manufacturers are not completely consistent, Frequency correction needs to be performed through a Frequency Correction Channel (FCCH).
Illustratively, a signal of a first pin of the slot and a signal of a second pin of the slot are stored in the register, the signal of the first pin is used for indicating whether a hard disk is inserted into the slot, and the signal of the second pin is used for indicating the type of the hard disk. The state information of the hard disk is determined by a target signal corresponding to the previous time when the hard disk is pulled out of the slot position, and the state information of the hard disk can be latched by a register, so that a signal of a first pin and a signal of a second pin in the latched register are respectively the same as the signal of the first pin and the signal of the second pin corresponding to the previous time when the hard disk is pulled out of the slot position.
Specifically, a signal of a first pin and a signal of a second pin of the slot are spliced and placed into a register of the CPLD, and the type of the hard disk inserted into the slot is determined according to a value in the register. For example: a register formed by the signal of the first pin and the signal of the second pin is (PRSNT, IFDET), and when the value of the register is (0, 0), the type of the inserted hard disk is determined to be SAS/SATA; when the register value is (1,0), confirming that the type of the inserted hard disk is NVME; when the register value is (1,1), it is confirmed that the hard disk is not inserted.
Furthermore, after the type of the hard disk is determined, analyzing the corresponding target signal to obtain the state information of the hard disk, and putting the state information of the hard disk into a register to form a data source channel. When the hard disk is pulled out of the slot position, the registers storing the first pin signal and the second pin signal are latched, and at the moment, the CPLD stops sampling the signal of the first pin and the signal level value of the second pin and keeps the register value at the previous moment before the hard disk is pulled out unchanged, so that the signal of the first pin and the signal of the second pin in the latched registers are respectively the same as the signal of the first pin and the signal of the second pin corresponding to the previous moment when the hard disk is pulled out of the slot position.
In the lighting method provided by the embodiment of the application, when any type of hard disk is inserted into the slot, the latch value of the register is formed according to the signal of the first pin and the signal of the second pin, and the data source channel formed by the register for storing the state data of the NVME hard disk and the register for storing the state information of the SAS/SATA hard disk is switched. For example: SAS/SATA hard disk state data analyzed through SGPIO signals are put into a register A to form a data source channel A, NVME hard disk state data analyzed through VPP signals are put into a register B to form a data source channel B, and a register (PRSNT, IFDET) formed by signals of a first pin and signals of a second pin is a register S. When the hard disk type in the slot at this moment is NVME, the destination signal output by the CPLD is a VPP signal, the value of the register S is (1,0), NVME hard disk state data analyzed through the VPP signal is stored in the register B, and the state information in the output destination signal is the state information in the register B at this moment. If the NVME hard disk in the slot position is pulled out, the CPLD stops sampling the state values of the signal of the first pin and the signal of the second pin, keeps the value of the register S unchanged, and outputs the state information in the target signal as the state information in the register B. When a SATA/SAS type hard disk is inserted into the slot again, the CPLD restarts to sample the state values of the signal of the first pin and the signal of the second pin, and the value of the register S is judged, so that the hard disk state data source is switched to be the register A. Therefore, the state information of the hard disks of the server backboard can be freely switched and locked when any type of hard disk is mixed and inserted.
In the mode, the signal of the first pin and the signal of the second pin of the slot position are stored in the register, and the register is latched after the hard disk is pulled out of the slot position, so that the effect that the output target signal can be obtained when the hard disk is pulled out is achieved. After the hard disk types are changed, the data channels can be switched, so that the data source channels of the state information of the corresponding hard disks can be freely switched and latched under the condition of mixed insertion of any hard disks.
Furthermore, the hard disk indicator lamp corresponding to the type of the hard disk is lighted up according to the state information in the output target signal. The state information in the output target signal register can be filled in the hard disk indicating lamp register, and the hard disk indicating lamp is lighted up through the hard disk indicating lamp control module.
Fig. 4 is a schematic diagram of a process of implementing lighting operation of the hard disk indicator lamp by the hard disk indicator lamp control module. As shown in fig. 4, the NVME register value is status information of the hard disk parsed from the VPP signal, the SATA register value is status information of the hard disk parsed from the SPGIO signal, and the NVME register value and the SATA register value enter the MUX combining circuit as two input signals. The register value formed by the first pin signal and the second pin signal can select the register value at the output end of the MUX combinational circuit, wherein the register value at the output end can be an NVME register value or an SATA register value. And the output end register value is filled into the hard disk indicator lamp register, so that the hard disk indicator lamp is lighted through the hard disk indicator lamp control module according to the hard disk indicator lamp register value.
If the hard disk is not accessed in the slot position after electrification, namely in the initial state, the CPLD detects that the signal of the first pin is high level, the register value of the hard disk indicator light is filled to be low level, and no light-on operation is executed at the moment. When the hard disk is inserted into the slot, the first pin signal is still at a low level, the type of the inserted hard disk is judged to be an unidentifiable type, and at the moment, no lighting operation is executed, for example: the inserted hard disk interface conforms to, but the hard disk is not a storage class hard disk. When the type of the inserted hard disk is in accordance with the type of the inserted hard disk, the register value of the hard disk of the corresponding type is selected to be filled into the register value of the hard disk indicating lamp, and the hard disk indicating lamp control module lights the hard disk indicating lamp of the corresponding hard disk. For example, if the inserted hard disk is NVME, the corresponding NVME register value is used as an output target signal by the MUX, the NVME register value is filled into the hard disk indicator lamp register value, and the hard disk indicator lamp of the NVME hard disk is lightened by the hard disk indicator lamp control module; when the type of the inserted hard disk is SAS or SATA, the corresponding SAS or SATA register value is used as an output target signal by MUX, the SAS or SATA register value is filled into the register value of the hard disk indicating lamp, and the hard disk indicating lamp of the SAS or SATA hard disk is lightened by the hard disk indicating lamp control module. At a certain moment, after the hard disk is pulled out, the CPLD latches a (PRSNT, IFDET) register consisting of the signal of the first pin and the signal of the second pin, so that the current state information of the hard disk still keeps the state information of the hard disk determined by the target signal corresponding to the moment before the hard disk is pulled out. Therefore, the hard disk indicating lamp can be lightened according to the state information of the hard disk. For example: at the moment, the type of the hard disk in the slot position is NVME, after the NVME hard disk is pulled out, the target signal of the current hard disk state information source is still a VPP signal, so that the pulled-out NVME hard disk state information can be analyzed according to the VPP signal and a corresponding hard disk indicator lamp is lightened; if the type of the hard disk in the slot position is SAS or SATA, after the SAS or SATA hard disk is pulled out, the target signal of the current hard disk state information source is still the SPGIO signal, so that the state information of the pulled-out SAS or SATA hard disk can be analyzed according to the SPGIO signal and the corresponding hard disk indicator lamp is lightened.
According to the hard disk lighting method provided by the embodiment of the application, when the slot position of the server backboard is pulled out of the hard disk is detected, the state information of the hard disk is determined according to the target signal corresponding to the previous moment when the slot position of the server backboard is pulled out of the hard disk, the target signal comprises the SGPIO signal or the VPP signal, and then the hard disk indicator lamp corresponding to the type of the hard disk is lighted up according to the state information of the hard disk. After the hard disk is pulled out, the state information of the hard disk is determined according to the target signal at the previous moment when the hard disk is pulled out of the slot position, and the hard disk indicator lamp is turned on according to the state information of the hard disk. After the hard disk is pulled out of the slot position, the state information of the hard disk is determined according to the target signal at the previous moment when the hard disk is pulled out of the slot position, and the lighting operation of the hard disk indicator lamp is realized according to the state information of the hard disk, so that a user can quickly and accurately determine the type and the state information of the hard disk pulled out of the slot position, the phenomenon that data cannot be stored or lost due to the replacement of the hard disk with the wrong type is avoided, and the efficiency and the accuracy of replacing the hard disk are improved.
