1、查看服务器型号
1 [root@localhost ~]# dmidecode | grep "Product"
2 Product Name: RH2288H V3
3 Product Name: BC11H****2、查看服务器的序列号
1 [root@localhost ~]# dmidecode -t system | grep 'Serial Number'
2 Serial Number: 2102311QGG10********3、统一查看服务器SN序列号和型号
1 [root@localhost ~]# dmidecode | grep "System Information" -A9 | egrep "Manufacturer|Product|Serial"
2 Manufacturer: Huawei
3 Product Name: RH2288H V3
4 Serial Number: 2102311QGG10********4、查看CPU信息
备注：两种方法lscpu可以查看CPU的完整信息或者cat /proc/cpuinfo
5、查看GPU显卡信息
通过$ nvidia-smi -q 查看BUS-ID和显卡的序列号之间的对应关系
[root@localhost ~]# nvidia-smi -q

**************************************信息很多，再往下拉可以看到显卡的BUS-ID 信息和相对应的序列号（Serial Number）。那这张显卡插在哪个PCIE卡槽？
通过dmidecode -t slot 查看BUS-ID （BUS Address）和卡槽的对应关系：
[root@localhost ~]# dmidecode -t slot
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.3.0 present.
# SMBIOS implementations newer than version 3.2.0 are not
# fully supported by this version of dmidecode.
Handle 0x0025, DMI type 9, 17 bytes
System Slot Information
Designation: CPU0_PE1_SLOT3
Type: x16 <OUT OF SPEC>
Current Usage: In Use
Length: Long
Characteristics:
3.3 V is provided
Opening is shared
PME signal is supported
Bus Address: 0000:34:00.0可以看到BUS对应的卡槽为SLOT3，SLOT标号一般在主板上，白色字体，在每个PCIE插槽（很长的那个插槽，插显卡的）的上方。
还可以通过 dmidecode -t slot | egrep -i "slot|add" 查看 （输出更简洁），输出类似于：
[root@localhost ~]# dmidecode -t slot | egrep -i "slot|add"

1、用“df -h”命令；
2、用“lsblk”命令；
3、用“sudo lshw -class disk”命令；
4、用“fdisk -l”命令；
5、用“cat /proc/partitions”命令；
6、用“lsscsi”命令
7、查看内存插槽信息及使用情况
