dmidecode可以查看服务器硬件的详细配置,下面是DMI的类型：
语法格式：DB01:~ # dmidecode --help
Usage: dmidecode [OPTIONS]
Options are:
-d, --dev-mem FILE Read memory from device FILE (default: /dev/mem)
-h, --help Display this help text and exit
-q, --quiet Less verbose output
-s, --string KEYWORD Only display the value of the given DMI string
-t, --type TYPE Only display the entries of given type
-u, --dump Do not decode the entries
-V, --version Display the version and exit
