The access command sending step (a) is a step in which the cpu 21 of an i-th server 2, which performs Power-On Self-Test (POST) in the Power-On mode, sends an access command to the bmc 23 of the i-th server via the stage path controller 22.
The step (B) of determining the original configuration file is that the bmc 23 of the i-th server 2 receives the access command via the platform path controller 22, and determines whether the backup BIOS configuration parameters related to the i-th server 2 are stored according to the access command.
The step (C) of determining the backup aggregation file is to determine whether a backup BIOS configuration parameter corresponding to the ith server 2 is stored in a jth server 2 corresponding to the ith server 2 according to the backup comparison table if the determination result of the step (B) of determining the original configuration file is negative.

The sub-step (C2) of requesting the backup file is as follows: the bmc 23 of the ith server 2 issues a request command to the jth server 2 according to the backup server information.
The query backup file sub-step (C3) is: the jth server 2 determines whether to store the backup BIOS configuration parameters corresponding to the ith server 2.
Referring to fig. 4 again, the step (D) of receiving the backup cluster file is: if the sub-step (C3) of querying the backup file is yes, the bmc 23 of the ith server 2 receives the backup BIOS configuration parameters from the jth server 2, and then the bmc 23 of the ith server 2 stores the received backup BIOS configuration parameters, wherein the bmc 23 of the ith server 2 stores the received backup BIOS configuration parameters in the persistent memory corresponding to the bmc 23 of the ith server 2.

The step (F) of storing the configuration file is as follows: if the sub-step (C3) of querying the backup file is no, the cpu 21 of the ith server 2 notifies the bmc 23 of the ith server to store the existing BIOS configuration parameters, that is, the BIOS configuration parameters currently stored in the BIOS memory 24 are stored in the bmc 23 of the ith server, the bmc 23 of the ith server stores the existing BIOS configuration parameters in the corresponding permanent memory, and the bmc 23 of the ith server further transmits the stored existing BIOS configuration parameters to the bmc 23 of the corresponding server 2 of the ith server 2 according to the backup comparison table, for example, the bmc 23 of the jth server 2, so that the bmc 23 of the jth server 2 stores the existing BIOS configuration parameters of the ith server in the corresponding permanent memory of the bmc 23 of the jth server 2 More specifically, the cpu 21 of the ith server 2 transmits the BIOS configuration parameters stored in the BIOS memory 24 to the bmc 23 also located in the ith server 2 through the platform path controller 22, so as to transmit the BIOS configuration parameters stored in the BIOS memory 24 and a backup instruction to the bmc 23 of the corresponding server 2 corresponding to the ith server 2 through the bmc 23 of the ith server 2, for example, the bmc 23 of the jth server 2 for backup storage, wherein the ith server 2 and the jth server 2 are both disposed in the same server rack, and the bmc 23 of the ith server 2 and the bmc 23 of the jth server 2 are electrically connected, for example, the bmc 23 of the ith server 2 and the bmc 23 of the jth server 2 may communicate with each other through the bus included in the server rack, or may communicate with each other through the internal network of the server rack.
Referring to FIG. 6, the store configuration file step (F) specifically includes an access original BIOS configuration parameters sub-step (F1), and an update look-up table sub-step (F2).
Step (F1): if the determination result in the step (C) is negative, the central processing unit 21 of the i-th server 2 obtains a BIOS configuration parameter from the corresponding BIOS memory 24, so as to transmit the BIOS configuration parameter to the bmc 23 of the i-th server 2 for storage as the backup BIOS configuration parameter.
Step (F2): the bmc 23 of the ith server 2 transmits the backup BIOS configuration parameter to the board management controller 23 of the jth server 2, and updates the backup comparison table stored in the bmc 23 of the ith server 2 to record the backup BIOS configuration parameter stored in the ith server 2 by the jth server 2, wherein the backup comparison table further includes the latest transmission time for the bmc 23 of the ith server 2 to transmit the BIOS configuration parameter to the board management controller 23 of the jth server 2.
Referring to fig. 4, the step (G) of updating the backup cluster file is: the bmc 23 of the ith server 2 updates the backup BIOS configuration parameter stored in the bmc 23 of the ith server 2 with the changed BIOS configuration parameter, and transmits the changed backup BIOS configuration parameter to the bmc 23 of the corresponding jth server 2 according to the backup comparison table, so as to update the stored backup BIOS configuration parameter.
Referring to FIG. 7, the step (G) of updating the backup aggregate file specifically includes a sub-step (G1) of determining a change in file parameters and a sub-step (G2) of updating file parameters.
The file parameter change determining substep (G1) is: when the central processing unit 21 of the i-th server 2 in the boot mode determines that the BIOS configuration parameter stored in the BIOS memory 24 has a variation, the central processing unit 21 transmits the varied BIOS configuration parameter to the baseboard management controller 23 of the i-th server 2 so that the baseboard management controller 23 of the i-th server 2 updates the backup BIOS configuration parameter stored therein.
The sub-step (G2) of updating the file parameters is as follows: the bmc 23 of the ith server 2 transmits the updated backup BIOS configuration parameters to the bmc 23 of the jth server 2 according to the backup comparison table stored therein, so that the updated backup BIOS configuration parameters are updated and stored in the bmc 23 of the jth server 2.
In the above embodiment, the backup comparison table is used to record the corresponding relationship between each server 2 and another server 2 providing the backup BIOS configuration parameters, if one of the servers 2 is a new node after the previous damaged server 2 is replaced, when it is in the power-on mode to perform the power-on self-test and it is determined that the memory corresponding to the baseboard management controller itself does not store the backup BIOS configuration parameters, the server 2 belonging to the new node can receive the backup BIOS configuration parameters of the previous damaged server 2 from the corresponding server 2 according to the backup comparison table, if the corresponding server 2 does not store the backup BIOS configuration parameters of the previous damaged server 2, the server 2 belonging to the new node automatically transmits the BIOS configuration parameters of itself, i.e. the local BIOS configuration parameters, that is, the BIOS configuration parameters currently stored in the memory 24 are transmitted to the corresponding server 2 according to the backup comparison table for backup storage by the corresponding server 2, therefore, the BIOS configuration parameters can be automatically recovered without manual updating or adding additional hardware to backup the BIOS configuration parameters, thereby really achieving the creation purpose of the invention.
However, the above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the contents of the patent specification should be included in the scope of the present invention.
