背景
各种场景都需要获取服务器的SN(Serial Number),比如问题定位,文件命名,该部分信息在dmi中是标准信息,不同服务器,不同os都能用相同方式获取SN信息。本文记录快速获取SN的方式。
在“dmidecode”中,DMI是“Desktop Management Interface”的缩写,即桌面管理接口。
DMI是一种基于SMBIOS(System Management BIOS)的标准,它提供了一种在计算机系统中访问和管理硬件信息的方法。通过DMI,系统管理员和用户可以获取有关计算机硬件组件的详细信息,如处理器、内存、硬盘、主板、显卡等的规格、型号、序列号等。dmidecode工具就是利用DMI标准来获取并解码这些信息,以人类可读的格式呈现给用户,方便用户了解计算机硬件的配置情况。
命令
dmidecode -t 1
或者:
dmidecode -t system
