Embodiment 1

[0041] see figure 1 , figure 1 It is a schematic structural diagram of a single NVMe hard disk backplane supporting dual lighting provided by the embodiment of the present application. The single NVMe hard disk backplane in this application is also called single-port NVMe hard disk backplane, which is a backplane that can only accommodate one NVMe hard disk. Depend on figure 1 It can be seen that the single NVMe hard disk backplane in this embodiment mainly includes: a CPLD, a first connector, a second connector and a third connector. Among them, the first connector is connected to the PCIEX4, VPP, PE_RESET signals of the CPU through the side board, the second connector is connected to the IIC signal of the BMC through the cable line, and the third connector is connected to an NVMe hard disk.

[0042] That is, the PCIEX4, VPP, and PE_RESET signals of the CPU are connected to the first connector of the single NVMe hard disk backplane through the side board, supporting data i...

Embodiment 2

[0057] exist figure 1 and figure 2 On the basis of the illustrated embodiment see image 3 , image 3 It is a schematic flow chart of a hard disk backplane lighting method provided by the embodiment of the present application. Depend on image 3 It can be seen that the lighting method of the hard disk backplane in this embodiment includes:

[0058] S1: The CPLD detects the presence information of the NVMe hard disk, and transmits the presence information of the NVMe hard disk to the CPU through the VPP signal.

[0059] The in-position information of the NVMe hard disk includes: Locate information and Error information, that is, the location of the NVMe hard disk and whether there is an error in the location of the hard disk.

[0060] S2: The CPU sends the first lighting signal to the CPLD according to the presence information of the NVMe hard disk.

[0061] In this embodiment, the first lighting signal is a lighting signal sent by the CPU to the CPLD.

[0062] S3: The ...

Abstract

The present application discloses a single NVMe hard disk backboard supporting double lighting and a lighting method of the hard disk backboard. The single NVMe hard disk backboard comprises a CPLD, afirst connector, a second connector, and a third connector; the first connector is in signal connection with PCIEX4, VPP and PE_RESET of a CPU through a side board; the second connector is in signalconnection with IIC of BMC through a cable; and the first connector is connected with a NVMe hard disk. The CPLD is used for analyzing a lightning signal from the CPU, detecting the in-position information of the NVMe hard disk, transmitting the in-position information to the CPU through a VPP signal, carrying out information interaction with the BMC through the IIC signal and controlling an IO signal between the CPLD and an indicator light. According to the single NVMe hard disk backboard supporting double lighting and the lighting method of the hard disk backboard in the application, the PCA9555 chip in the prior art is replaced with the CPLD; the CPLD is respectively in communication connection with the CPU and the BMC so that the single NVMe hard disk backboard in the application cannot only achieve VPP lighting but also can achieve BMC lighting; the lighting path is increased; and improvement of the flexibility of lighting is facilitated.

Description

technical field [0001] The present application relates to the technical field of server hard disk backplanes, in particular to a single NVMe hard disk backplane supporting dual lighting and a lighting method for the hard disk backplane. Background technique [0002] With the development of high-density servers, a single NVMe hard disk backplane is gradually coming out. The single NVMe hard disk backplane is also called a single-port NVMe hard disk backplane. The board can effectively increase the boot speed and the storage speed of important data, and can also significantly increase the storage capacity of the server. In order to monitor the running status of NVMe hard disks, it is an important issue to turn on the lights on a single NVMe hard disk backplane. [0003] The current single NVMe hard disk backplane usually uses the PCA9555 chip to analyze the VPP signal for lighting. Specifically, when entering the OS system of the server where the current single NVMe hard disk...
