2、dmidecode

dmidecode, 使用该命令可以查询BIOS、系统、主板、处理器、内存、缓存等非常重要信息。下面是其常用的几个命令:

# dmidecode | grep 'Product Name' // 查看服务器型号
# dmidecode | grep 'Serial Number' // 查看主板的序列号
# dmidecode -s system-serial-number // 查看系统序列号
# dmidecode -t memory // 查看内存信息
# dmidecode -t 11 // 查看OEM信息
# dmidecode | grep "Maximum Capacity" |sed "s/^[ \t]*//" // 最大支持内存容量：

(1)查看内存信息（例）

sudo dmidecode -t memory
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.2.0 present.
