技术领域technical field
本发明涉及计算机服务器设计技术领域，具体涉及一种DMI同步FRU的方法。The invention relates to the technical field of computer server design, in particular to a method for DMI synchronizing FRUs.
背景技术Background technique
DMI（Desktop Management Interface，桌面管理接口）的主要组成部分是Management Information Format（MIF）数据库。这个数据库包括了所有有关服务器系统和配件的信息。通过DMI的MIF数据库，用户可以获取序列号、厂商、资产号信息以及其它系统配件信息。SMBIOS是主板或系统制造者以标准格式显示产品管理信息所需遵循的统一规范。 DMI 是帮助收集电脑系统信息的管理系统，DMI信息的收集必须在严格遵照SMBIOS规范的前提下进行。SMBIOS和DMI是由行业指导机构Desktop Management Task Force（DMTF）起草的开放性的技术标准，其中，DMI设计适用于任何的平台和操作系统。DMI充当了管理工具和系统层之间接口的角色。它建立了标准的可管理系统更加方便了计算机厂商和用户对系统的了解。计算机系统管理与维护人员可以通过DMI中系统的序列号、厂商、资产号等信息对系统进行方便的统一管理。The main component of DMI (Desktop Management Interface, desktop management interface) is the Management Information Format (MIF) database. This database includes all information about server systems and accessories. Through DMI's MIF database, users can obtain serial number, manufacturer, asset number information and other system accessories information. SMBIOS is a unified specification that motherboard or system manufacturers need to follow to display product management information in a standard format. DMI is a management system that helps collect computer system information. The collection of DMI information must be carried out under the premise of strictly following the SMBIOS specification. SMBIOS and DMI are open technical standards drafted by the industry guidance organization Desktop Management Task Force (DMTF). Among them, DMI design is applicable to any platform and operating system. DMI acts as an interface between management tools and system layers. It has established a standard manageable system, which is more convenient for computer manufacturers and users to understand the system. Computer system management and maintenance personnel can conveniently and uniformly manage the system through information such as the serial number, manufacturer, and asset number of the system in the DMI.
FRU（Field Replace Unit 现场可更换单元）是用来记录系统配置的另一项重要指标，服务器系统把设备分成多个FRU，大到power supply，小到fan等设备，对于服务器系统，FRU信息保存在主板BMC（Baseboard Management Controller，基板管理控制器）的EEPROM中，掉电不易失。通过BMC，用户可以远程带外查看服务器系统的配置信息，方便易于管理。FRU (Field Replace Unit Field Replaceable Unit) is another important index used to record system configuration. The server system divides the device into multiple FRUs, ranging from power supply to fan. For the server system, FRU information is saved In the EEPROM of the motherboard BMC (Baseboard Management Controller, baseboard management controller), it is not easy to lose power loss. Through the BMC, users can remotely view the configuration information of the server system out of band, which is convenient and easy to manage.
DMI信息存在于服务器HOST主系统中，FRU保存在服务器BMC系统中，为了便于系统管理，可以将DMI中的配置信息与FRU信息同步，这样两者就可以保持一致。The DMI information exists in the main system of the server HOST, and the FRU is stored in the server BMC system. In order to facilitate system management, the configuration information in the DMI can be synchronized with the FRU information, so that the two can be consistent.
传统DMI同步FRU掉电DMI Table易丢失，且难以保证DMI与FRU信息的一致性。Traditional DMI synchronization FRU power failure DMI Table is easy to lose, and it is difficult to ensure the consistency of DMI and FRU information.
发明内容Contents of the invention
为解决上述问题，本发明的目的在于提供一种DMI同步FRU的方法，从BMC中同步FRU信息成功，更新完DMI Table后，会将DMI Table的内容保存到NVRAM中，掉电不易失。当从BMC中同步FRU信息失败时，会从NVRAM中读取上次同步成功的DMI信息，去更新DMI Table，以保证DMI与FRU信息的一致性。In order to solve the above problems, the object of the present invention is to provide a method for synchronizing FRU with DMI. The FRU information is successfully synchronized from the BMC. After updating the DMI Table, the content of the DMI Table will be saved in the NVRAM, which is not easy to lose when power off. When the synchronization of FRU information from BMC fails, the DMI information that was successfully synchronized last time will be read from NVRAM to update the DMI Table to ensure the consistency of DMI and FRU information.
为实现上述目的，本发明的技术方案为：To achieve the above object, the technical solution of the present invention is:
