Linux查看硬件信息

1. 最简单的的显示全部dmi信息：

<b> # dmidecode</b>

这样将输出所有的dmi信息，你可能会被一大堆的信息吓坏，通常可以使用下面的方法。

2.更精简的信息显示：

<b># dmidecode -q</b>

-q(--quite) 只显示必要的信息，这个很管用哦。

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：

<b># dmidecode -t bios</b>

# dmidecode -t bios, processor (这种方式好像不可以用，必须用下面的数字的方式)

<b># dmidecode -t 0,4</b>  (显示bios和processor)

服务器到底能扩展到多大的内存？

[root@TJSJHL218-154 setup]# dmidecode -t 16

# dmidecode 2.9

SMBIOS 2.5 present.
