Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a lighting method and lighting system for an NVMe hard disk based on a Feiteng server. Background Art

[0002] Currently, Feiteng servers' central processing units (CPUs) support a limited number of PCIE (peripheral component interconnect express) ports, requiring expansion through a PCIE bridge. However, different motherboards require different port configurations, resulting in dynamic changes in the PCIE device number assigned by NVMe (NVM Express). Furthermore, existing hard drive backplane designs primarily utilize the SFF-8485 protocol to illuminate SAS / SATA hard drives. This protocol does not support the in-band pins of NVMe hard drives, so existing backplane designs do not support NVMe hard drive illumination.

[0003] At present, in the field of computer server technology, in Chinese patent documents, there is a patent application titled "A hard disk lighting method, device, electronic device and storage medium" with application number CN201910968215.5, which introduces a hard disk lighting method, the method comprising: obtaining the drive letter of the target hard disk, and judging whether the target hard disk is a hard disk directly connected to the PCH based on the drive letter; if so, determining the slot identifier corresponding to the target hard disk through hardware connection, and determining the I2C address corresponding to the slot identifier; switching the I2C switch to the channel connected to the CPLD, and sending a lighting command including the I2C address to the CPLD through the BMC, so that the CPLD sends a lighting command to the I2C address to complete the lighting operation of the target hard disk.

Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the following detailed description is illustrative rather than restrictive and should not be used to limit the scope of protection of the present invention.

[0029] In view of the problems existing in the existing technology, such as Figure 1 As shown, an embodiment of the present invention provides a backplane lighting method for an NVMe hard disk based on a Feiteng server, comprising the steps of:

[0030] S20: Obtaining a card type of a card connected to a motherboard slot through a motherboard CPLD, and obtaining configuration information of the NVMe hard disk according to the card type and a pre-set first comparison table, wherein the first comparison table includes the card type and the configuration information corresponding to the card type;

[0031] S40: configuring the PCIE bridge chip through the mainboard CPLD according to the configuration information;

[0032] S60: The hard disk status of the NVMe hard disk detected by the motherboard BMC obtains the lighting instruction from the pre-set second comparison table, and transmits the lighting instruction to the backplane CPLD, so that the backplane CPLD lights up according to the lighting instruction. The second comparison table includes the NVMe hard disk status and the lighting instruction corresponding to the NVMe hard disk status.

[0033] In this embodiment, the card type of the card connected to the motherboard slot is obtained, and the configuration information of the NVMe hard disk is obtained according to the card type and a pre-set first comparison table. Then, the PCIE bridge chip is configured through the motherboard CPLD according to the configuration information. Then, the hard disk status of the NVMe hard disk detected by the motherboard BMC is used to obtain a lighting instruction from a pre-set second comparison table, and the lighting instruction is transmitted to the backplane CPLD so that the backplane CPLD turns on the light according to the lighting instruction. The embodiment provided by the present invention can solve the problem that the PCIE port of Feiteng server is limited and does not support the lighting protocol of NVMe hard disk, and has practical application value.

[0034] In a specific example, Figure 2 The figure shows a lighting system, including a motherboard and a backplane, wherein the motherboard includes a motherboard CPLD, a motherboard BMC, a PCIE bridge chip and a motherboard slot, and the backplane includes a backplane CPLD, an NVMe physical slot, and multiple LED display lights. In this embodiment, the motherboard CPLD is used to start the Feiteng server, the motherboard BMC is used to send instructions to the backplane CPLD, the PCIE bridge chip is used to configure the PCIE port of the NVMe hard drive, and the motherboard slot is used to access the backplane; the backplane CPLD is used to control and manage the various components on the backplane, the NVMe physical slot is used to access the NVMe hard drive, and the multiple LED display lights are used to display the status of the NVMe hard drive; as shown in FIG. Figure 2 As shown, the mainboard also includes an interface expansion chip (IO EXPANDER) and a mainboard low-speed connector, and the backplane also includes a backplane low-speed connector. The mainboard CPLD reads the interface expansion chip through the I2C bus to obtain the board identifier of the board connected to the mainboard slot, and obtains the corresponding board type according to the board identifier; the mainboard low-speed connector is used to connect to the backplane low-speed connector to realize communication between the mainboard and the backplane.

[0035] In this embodiment, the board identifier is a port value formed after the board is connected. Specifically, the mainboard includes multiple input and output ports, wherein three input and output ports are provided with pull-up and pull-down resistors. When connected to different backplanes, the three input and output ports form a board identifier corresponding to the connected backplane. For example, as shown in Table 1, the three input and output ports form a 3-bit board identifier, which can represent 8 types of board types.

[0036] Table 1 First comparison table

[0037]

[0038] As shown in Table 1, this is a first comparison table pre-set in this embodiment. The first comparison table includes the board type and the configuration information corresponding to the board type. The configuration information includes the NVMe device number, the NVMe physical slot, the register address of the backplane CPLD, and the bus channel connected to the backplane CPLD.

[0039] In this embodiment, the lighting method specifically includes:

[0040] In the first step, the motherboard CPLD obtains the board type of the board connected to the motherboard slot, and obtains the configuration information of the NVMe hard disk inserted into the NVMe physical slot of the backplane according to the board type and the preset first comparison table.

[0041] The second step is to configure the PCIE bridge chip through the motherboard CPLD according to the configuration information. Specifically, according to the configuration information, the motherboard CPLD configures the general input and output ports of the PCIE bridge chip to allocate the PCIE device number of the NVMe hard drive.

[0042] The third step is to obtain the lighting instruction from the preset second comparison table through the hard disk status of the NVMe hard disk detected by the motherboard BMC, and transmit the lighting instruction to the backplane CPLD, so that the backplane CPLD lights up the LED display light according to the lighting instruction. The second comparison table includes the NVMe hard disk status and the lighting instruction corresponding to the NVMe hard disk status.

[0043] like Figure 2 As shown, specifically, the mainboard BMC transmits the lighting instruction to the mainboard low-speed connector through the I2C bus, transmits it to the backplane low-speed connector through the mainboard low-speed connector, and transmits it to the backplane CPLD through the backplane low-speed connector.

[0044] As shown in Table 2, the second comparison table includes the NVMe hard disk status and the lighting instruction corresponding to the NVMe hard disk status. The motherboard BMC generates a lighting instruction based on the detected NVMe hard disk status and the second comparison table, and transmits it to the backplane CPLD, thereby realizing control of each LED display light through the backplane CPLD, that is, lighting the corresponding LED indicator light according to the NVMe hard disk status, thereby solving the problem that the PCIE port of the Feiteng server is limited and does not support the lighting protocol of the NVMe hard disk, and has practical application value.

[0045] Table 2 Second comparison table

[0047] To further illustrate the specific implementation of this application, a specific example is given below:

[0048] The first step is to identify the board type

[0049] After the motherboard is plugged into the power supply, the motherboard CPLD will perform I2C communication with the interface expansion chip IO EXPANDER chip, read the three general input and output ports to obtain the board identification 010, and confirm that the board type is 2 according to the first comparison table. The PCIE device numbers corresponding to the NVMe device are number 0, number 1, number 2, and number 3, respectively. Among them, the NVMe physical slot corresponding to number 0 is 0, the corresponding backplane CPLD register address is 0x70, and the corresponding I2C channel is channel 0. Similarly, the NVMe physical slot corresponding to number 1 is 1, the corresponding backplane CPLD register address is 0x71, and the corresponding I2C channel is channel 0. The NVMe physical slot corresponding to number 2 is 2, the corresponding backplane CPLD register address is 0x72, and the corresponding I2C channel is channel 0. The NVMe physical slot corresponding to number 3 is 3, the corresponding backplane CPLD register address is 0x73, and the corresponding I2C channel is channel 0.

[0050] That is, the motherboard CPLD reads the interface expansion chip through the I2C bus to obtain the board identification of the board connected to the motherboard slot, obtains the board type of the board according to the first comparison table, and then obtains the configuration information of the NVMe hard disk according to the board type and the first comparison table. The first comparison table includes the board type and the configuration information corresponding to the board type.

[0051] The second step is to configure the PCIE bridge chip on the motherboard CPLD

[0052] The motherboard CPLD performs PCIE configuration with the GPIO pins of the PCIE bridge, confirms that the PCIE device numbers corresponding to the NVMe devices are 0, 1, 2, and 3, respectively, and configures the PCIE bridge according to the corresponding configuration information. That is, based on the configuration information, the motherboard CPLD configures the general input and output ports of the PCIE bridge to allocate the PCIE device number of the NVMe hard drive.

[0053] The third step is to light the lamp.

[0054] First, according to the correspondence between the device number of the NVMe hard disk and the physical slot in the first comparison table of Table 1, for example, when the hard disk in physical slot 1 detected by the motherboard BMC is currently in the positioning state, according to the second comparison table, it can be known that the blue indicator light should be turned on. The motherboard BMC transmits the lighting instruction including 0010 to the motherboard low-speed connector through the I2C bus, and transmits it to the register address 0x71 of the backplane CPLD through the motherboard low-speed connector and the backplane low-speed connector.

[0055] Secondly, when the backplane CPLD detects that the register value in register address 0x71 is 0010, it will control the blue LED light of slot 1 to flash at a frequency of 4HZ, thereby lighting up according to the status of the NVMe hard drive.

[0056] Finally, when the motherboard BMC detects that the status of the NVMe hard disk has changed to normal, the lighting instruction including 0011 is again transmitted to the register of the register address 0x71 of the backplane CPLD according to Table 2, so that the blue LED light of the backplane CPLD control slot 1 is turned off, thereby realizing lighting according to the status of the NVMe hard disk.

[0057] That is, the hard disk status of the NVMe hard disk detected by the motherboard BMC obtains the lighting instruction from the pre-set second comparison table, and transmits the lighting instruction to the backplane CPLD, so that the backplane CPLD lights up according to the lighting instruction. The second comparison table includes the NVMe hard disk status and the lighting instruction corresponding to the NVMe hard disk status.

[0058] This embodiment obtains the board type of the board connected to the motherboard slot, obtains the configuration information of the NVMe hard disk according to the board type and a preset first comparison table, and then configures the PCIE bridge chip through the motherboard CPLD according to the configuration information. Then, the hard disk status of the NVMe hard disk detected by the motherboard BMC is obtained from the preset second comparison table, and the lighting instruction is transmitted to the backplane CPLD so that the backplane CPLD is turned on according to the lighting instruction. It can solve the problem that the PCIE port of the Feiteng server is limited and does not support the lighting protocol of the NVMe hard disk, and has practical application value.
