All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As described in the background, in the prior art, field replaceable unit information is generally burned and stored in an EEPROM, and the existence and stability of a BMC structure are excessively depended on. In the structural design of the server without the BMC, the burning of the field replaceable unit information can only be manually burnt in a physical hardware mode, and once the field replaceable unit information is changed, the change of the field replaceable unit information of the whole batch of servers is very complicated and difficult.

Example one
Specifically, as shown in fig. 1, the process of storing the field replaceable unit information by applying the method for storing the field replaceable unit information disclosed in this embodiment includes:
s100, acquiring field replaceable information of all equipment on a server;
a desktop management (Dmidcode) interface can be arranged in an operating system to realize the viewing and acquisition of field replaceable information of all devices; meanwhile, a desktop management tool is arranged in the operating system to realize the change of the field replaceable unit information under the operating system; the desktop management tool may be a DmiEdit (Dmi editing) tool or another tool that can modify the type information corresponding to the SMBIOS under the operating systems such as Linux, Windows, and Shell, which is not limited herein.
The software Dmidecode can acquire information about hardware under systems such as Linux. Dmidrecode follows the SMBIOS/DMI standard and outputs information including BIOS, system, motherboard, processor, memory, cache, etc. The DMI (Desktop Management Interface) is a Management system that helps collect information of a computer system, and the collection of DMI information must be performed under the premise of strictly complying with the SMBIOS specification. SMBIOS (System Management BIOS) is a unified specification that a motherboard or system manufacturer needs to follow to display product Management information in a standard format. Each computer produced by a mainboard manufacturer or an OEM manufacturer writes information into the BIOS according to the SMBIOS standard when the computer leaves a factory. Such information includes BIOS information, system information, processor information, device information, and the like. SMBIOS and DMI are open technical standards drafted by the industry guide agency Desktop Management Task Force (DMTF), where DMI designs are applicable to any platform and operating system. The DMI plays the role of the interface between the management tool and the system layer. It establishes standard manageable system, and is more convenient for computer manufacturers and users to know the system. The main component of DMI is the Management Information Format (MIF) database. This database contains all information about the computer system and accessories. Through DMI, a user can obtain serial numbers, computer manufacturers, serial port information and other system accessory information.
S200, recording field replaceable unit information into an SMBIOS information structure body;
s210, judging whether the information of the field replaceable unit is changed or not, and stopping operation when the information of the field replaceable unit is not changed;
checking the existing field replaceable unit information in the BIOS by using the desktop management interface, comparing the field replaceable unit information to be input, and if the field replaceable unit information to be input is the same as the existing field replaceable unit information in the BIOS, stopping the change operation without changing the field replaceable unit information in the BIOS;
s211, when the field replaceable unit information is changed, calling the SMBIOS changing interface, and recording the changed field replaceable unit information into an SMBIOS information structure body in the operating system;
if the field replaceable unit information needing to be input is different from the original field replaceable unit information of the BIOS, changing the original field replaceable unit information of the BIOS by using a desktop management tool preset in an operating system, and inputting the changed field replaceable unit information into an SMBIOS information structure body by using a preset retention rule;
wherein, the retention rule specifically means: because the correct field replaceable unit information format and field definition are particularly important for asset management and back-end operation and maintenance of a client, the format of the field replaceable unit information is set according to the field replaceable unit information format specified by the client; generating a field replaceable unit information structure according to the field replaceable unit information with the set format; and recording the field replaceable unit information structure body into a reserved word part in the SMBIOS information structure body.
And S300, acquiring the field replaceable unit information structural body from the SMBIOS information structural body and storing the field replaceable unit information structural body in a nonvolatile random access memory in a BIOS flash memory.
The nonvolatile random access memory is a part of rated storage space in the BIOS, has the same characteristic as the EEPROM, can be used for storing field replaceable unit information, and has larger redundancy in the utilization rate of the storage space in the nonvolatile random access memory;
wherein, a storage interface can be arranged in the nonvolatile random access memory for positioning the nonvolatile random access memory in the BIOS so as to store the information of the field replaceable unit; under normal conditions, the data stored in the nonvolatile random access memory has a characteristic of failure deletion after the operation of clearing a Complementary Metal Oxide Semiconductor (CMOS) chip is executed, so that the present application sets the field replaceable unit information in the BIOS as an attribute that is not changed after the CMOS chip is cleared. In the field of computers, CMOS often refers to a chip that stores basic startup information (such as date, time, startup settings, etc.) of a computer.
S400, the operating system return interface acquires the field replaceable unit information from the nonvolatile random access memory and displays the field replaceable unit information in the operating system.
Wherein, when the field replaceable unit is modified, the operating system return interface obtains the modified field replaceable unit information from the non-volatile random access memory; the operating system is restarted and the changed field replaceable unit information is displayed in the restarted operating system.
In addition, after the server is powered off and started, the state of the field replaceable unit information in the nonvolatile random access memory is checked, if the field replaceable unit information does not exist in the nonvolatile random access memory or the field replaceable unit information stored in the nonvolatile random access memory is inconsistent with the field replaceable unit information displayed in the operating system, the desktop management interface is called immediately, and the field replaceable unit information is stored again, so that the field replaceable unit information is stored in the nonvolatile random access memory.
In addition, in order to ensure the write-in authority of the field replaceable unit information and prevent the occurrence of safety events, the field replaceable unit information storage operation can be executed in the operating system by setting storage password verification, if the password verification is successful, the field replaceable unit information storage operation is executed, and if the password verification is unsuccessful, an alarm message is generated in the operating system to terminate the field replaceable unit information storage operation. Or may set the initial field replaceable unit information to unalterable content.
It is to be added that the BMC module does not exist in the server hardware structure designed according to the field replaceable unit information storage method provided by the present application, so that the problem of BMC link collision does not need to be considered.
In addition, in the hardware structure of the server, if the EEPROM storage hardware exists and an I2C (Inter-Integrated Circuit, two-wire serial bus) connection link is provided between the EEPROM storage hardware and the BIOS, the field replaceable unit information may also be stored in the EEPROM storage hardware through the I2C link to form a dual field replaceable unit information storage setting, so as to avoid that when a special fault occurs in one storage module, the safety and recoverability of the field replaceable unit information are ensured, and it is realized that in a BMC-free design scheme, the security of the server is optimized while no additional requirements are made on the hardware design of the server.
The field replaceable unit information storage method disclosed by the embodiment of the application can physically abandon the field replaceable unit information storage function of the EEPROM, increase the utilization rate of EEPROM storage space, simultaneously does not relate to interaction between the BMC and the EEPROM in the storage process, gets rid of the dependence on a BMC structure when the server stores the field replaceable unit information, and inputs the field replaceable unit information by using the BIOS, so that the field replaceable unit information is convenient to change and manage.
