Embodiment 1

[0037] Such as figure 2 As shown, the present invention provides a kind of system based on network remote refresh BMC firmware, comprising: BMC1, programmable logic device 2, network channel switching module 3 and BMC firmware storage module 4, network channel switching module 3 and BMC1 and BMC respectively Programmable logic device 2 communication connection, for BMC1 or programmable logic device 2 to obtain user command and data through network channel switching module 3, programmable logic device 2 is also respectively connected with BMC1, BMC firmware storage module 4 communication, for in Before the BMC firmware update, control the BMC1 to suspend operation, store the BMC firmware to be updated remotely sent by the user obtained by the network channel switching module 4 to the BMC firmware storage module 4, and control the BMC1 to continue working after the BMC firmware update is completed.

[0038] Further, it also includes a network interface controller 5 (NIC, namely...

Embodiment 2

[0050] Such as image 3 As shown, the technical solution of the present invention also provides a kind of method based on the remote refresh BMC firmware of the network, realizes on the basis of a kind of system based on the remote refresh BMC firmware of the network in embodiment one, comprises:

[0051] S1, before the BMC firmware is updated, the programmable logic device controls the BMC to suspend operation;

[0052] S3, the programmable logic device obtains the BMC firmware to be updated sent remotely by the user through the network channel switching module;

[0053] S5, the programmable logic device stores the acquired BMC firmware to be updated in the BMC firmware storage module;

[0054] S7, after the BMC firmware update is completed, the BMC is controlled to continue working.

[0055] Wherein, in step S1, the programmable logic device mainly realizes that the BMC suspends the operation by pulling up the reset signal of the BMC.

[0056] In step S3, the programmable...

Abstract

The invention provides a network-based system for remotely refreshing BMC firmware, which comprises a BMC, a programmable logic device, a network channel switching module and a BMC firmware storage module, and is characterized in that the network channel switching module is respectively in communication connection with the BMC and the programmable logic device; a BMC or a programmable logic device obtains user commands and data through a network channel switching module, the programmable logic device controls the BMC to stop running before BMC firmware is updated, and to-be-updated BMC firmware obtained through the network channel switching module and remotely sent by a user is stored in a BMC firmware storage module. The BMC is controlled to continue working after the BMC firmware is updated, the invention further provides a method for remotely refreshing the BMC firmware based on the network, normal updating of the BMC firmware can be achieved when the BMC firmware is attacked by hackers, and the updating efficiency is improved.

Description

technical field [0001] The invention relates to the field of BMC firmware update, in particular to a network-based system and method for remotely refreshing BMC firmware. Background technique [0002] BMC (Board Management Controller, Baseboard Management Controller) plays a very important role in the server architecture. It is mainly responsible for the management of the entire system, including monitoring power supply voltage, system temperature, fan control, system abnormality monitoring, and providing remote access. The function allows users to remotely operate the machine and understand the machine status. [0003] The powerful function of BMC makes server products highly dependent on it. If the BMC firmware is hacked and the BMC firmware is damaged, the customer must send personnel to the computer room to deal with it. When the situation is troublesome, it is even necessary to ask the supplier to send customer service personnel. deal with. [0004] Traditional server...
