Linux下查看硬件信息---Dmidecode

Dmidecode

 dmidecode以一种可读的方式dump出机器的DMI(Desktop Management Interface)信息。这些信息包括bios、cpu、内存等信息

1. 最简单的的显示全部dmi信息：
 # dmidecode
 这样将输出所有的dmi信息

 2.更精简的信息显示：
 # dmidecode -q
 -q(--quite) 只显示必要的信息

 3.显示指定类型的信息：
 通常我只想查看某类型，比如CPU，内存或者磁盘的信息而不是全部的。这可以使用-t(--type TYPE)来指定信息类型：
 # dmidecode -t bios

 # dmidecode -t 0,4  (显示bios和processor)
 

4. 服务器到底能扩展到多大的内存？

 #dmidecode -t 16

5. 查看Memory

#dmidecode -t 17
