[0022] The principles and spirit of the invention will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are provided merely to enable those skilled in the art to better understand and implement the invention, and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided to make the invention more thorough and complete, and to fully convey the scope of the invention to those skilled in the art.

[0023] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 The diagram illustrates the connection relationship between the backplane and the PCIe connector, and between the backplane and the hard drive, in the backplane hard drive illumination method according to an embodiment of the present invention.

[0025] refer to Figure 1 In this embodiment of the invention, a separate ID pin is provided on the PCIe connector side of the motherboard to distinguish PCIe ports. The PCIe connector pin displays the port identifier of the PCIe port; specifically, the port identifier can be represented by the values ​​ID0 / ID1 / ID2. The 3-digit IDs ID0, ID1, and ID2 can have 8 different combinations, including 000, 001, 010, 011, 100, 101, 110, and 111. In practical applications, the number of bits in the PCIe connector ID can be set according to requirements, for example, it can be 2, 3, 4, 5, or 6 bits.

[0026] The backplane CPLD on the backplane side can obtain the PCIe port information VPP_ADDR through the PCIe ID. Specifically, the correspondence between different PCIe IDs and the PCIe port information VPP_ADDR can be pre-stored. Then, after obtaining the PCIe ID value from the backplane CPLD, the PCIe port information VPP_ADDR is determined based on the PCIe ID value.

[0027] Furthermore, the backplane CPLD can parse the HP SMBus on the motherboard side based on VPP_ADDR to obtain the correct LED signal and transmit the LED signal to the corresponding hard drive. For example, the mapping of the PCIe port identifier, port information VPP_ADDR, and the bus number of the hard drive connected to the backplane is shown in Table 1 below:

[0028] Table 1

[0029]

[0030] When the backplane CPLD receives the LED signal from the motherboard side, indicating that the PCIe port information VPP_ADDR is 0x40, the PCIe port identifier can be obtained as 000. Furthermore, it can be determined that the hard drive that needs to be illuminated is connected to the backplane through the PE0A_B port.

[0031] It should be noted that, Figure 1 Table 1 is merely an illustrative example of this solution. In practical applications, VPP_ADDR can be flexibly configured as needed, and the PCIe port identifier is not limited to a 3-bit ID. Furthermore, in practical applications, it is not limited to one PCIe port corresponding to one backplane; multiple PCIe ports can be connected to the same backplane, or more backplanes can be connected to the motherboard. This invention does not limit the above content.

[0037] For example, refer back to the reference. Figure 1 The VPP_ADDR of a PCIe connector can be represented by the values ​​ID0 / ID1 / ID2. These three digits (ID0, ID1, ID2) can represent eight different combinations, including 000, 001, 010, 011, 100, 101, 110, and 111. In practical applications, the number of digits in the PCIe connector's ID can be set according to requirements, for example, it can be 2, 3, 4, 5, or 6 digits.
