Problems solved by technology

It is possible for a third-party attacker to rewrite the VPD information of the server power supply firmware of the storage server. When the server power supply firmware VPD is subjected to a rewriting attack, the server will reject the server power supply firmware, and the system will "mistakenly" alarm that the server power supply firmware is faulty. Because the upper-layer operating system OS of the system does not recognize the server power supply firmware, the system will automatically and quickly reduce the frequency from a few Ghz to 133Mhz, resulting in the server being unable to provide external services and causing major losses to customer applications
If you directly pull up to a high level to enable write protection, when you need to write data into the server power supply firmware, you need to modify the hardware circuit to remove the provided high level, which increases the complexity of the site maintenance engineer's operation , the maintenance cost is very high

Embodiment 1

[0057] see figure 1 , figure 1 It is an implementation flowchart of a server power supply firmware write protection control method in an embodiment of the present invention, and the method may include the following steps:

[0058] S101: Receive a server power supply firmware data writing request.

[0059] When data needs to be written into the server power supply firmware, that is, when power supply VPD information needs to be written into the server power supply firmware, a server power supply firmware data writing request is sent to the BMC. The baseboard management controller receives a server power supply firmware data writing request.

[0060] S102: Generate a write protection release command.

[0061] After receiving the server power supply firmware data write request, a write protection release command is generated.

[0062] S103: Send a write protection release instruction to the power supply micro-control chip, so that the power supply micro-control chip controls ...

Embodiment 2

[0069] see figure 2 , figure 2 It is another implementation flowchart of the server power supply firmware write protection control method in the embodiment of the present invention, and the method may include the following steps:

[0070] S201: Receive a server power supply firmware data writing request.

[0071] S202: Generate a write protection release command.

[0072] S203: Pass I 2 The C bus sends a write protection release command to the power microcontroller chip.

[0073] Baseboard Management Controller via I 2 The C bus establishes a communication connection with the power microcontroller chip, and after generating the write protection release command, through the I 2 The C bus sends a write protection release command to the power microcontroller chip.

[0074] S204: Send a filtering command to the pre-deployed target filter, so that the target filter performs filtering processing on the write protection release command according to the filtering command, and ...

Abstract

The invention discloses a server power supply firmware write-protection control method. The method comprises the following steps: receiving a server power supply firmware data write-in request; generating a write protection release instruction; sending a write protection release instruction to the power supply micro-control chip to enable the power supply micro-control chip to control the server power supply firmware to release write protection; and writing the to-be-written data corresponding to the server power supply firmware data writing request into the server power supply firmware. By applying the technical scheme provided by the embodiment of the invention, the flexibility of write protection control on the server power supply firmware is greatly improved, the operation complexity is reduced, and the maintenance cost is reduced. The invention further discloses a server power supply firmware write protection control device and equipment and a storage medium, and the correspondingtechnical effects are achieved.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a server power supply firmware write protection control method, device, equipment and computer-readable storage medium. Background technique [0002] In order to facilitate the management of server power supply firmware (PSU, Power Supply Unit), the system baseboard management controller (BMC, Baseboard Management Controller) usually reads (VPD, VitalProduct Data, Serial Number) information (such as Serial Number, VPD Length, FRU Part Number, Manufacturer Name, Power Capacity, VPD Version, Manufacturer Serial Number and other information) to check whether the server power supply firmware is a component supported by system certification. If the checked information is incorrect, the server power supply firmware will not be supported by the system. The system will "falsely" alarm the server power supply firmware failure. [0003] In recent years, attacks against servers ha...
