2、查询所有的pci设备信息（pci是一种总线，而通过pci总线连接的设备就是pci设备了，如今，我们常用的设备很多都采用pci总线了，如网卡存储等）
使用命令：lspci
得到结果：
:00.0 Host bridge: Intel Corporation Xeon E5 v2/Core i7 DMI2 (rev )
:01.0 PCI bridge: Intel Corporation Xeon E5 v2/Core i7 PCI Express Root Port 1a (rev )

4、查看系统内核相关信息
使用命令：uname -a
结果：
Linux cn13 2.6.-.el6.x86_64 # SMP Sun Nov :: EST x86_64 x86_64 x86_64 GNU/Linux
查看系统版本
使用命令：cat /etc/issue
结果：
Red Hat Enterprise Linux Server release 6.5 (Santiago)
5、利用dmindecode查看硬件信息
查看服务器型号
dmidecode | grep 'product name'
查看主板序列号
dmidecode | grep 'Serial Number'
查看系统序列号
dmidecode -s systems-serial-number
查看内存信息
dmidecode -t memory
查看oem信息
dmidecode -t 11
**6、利用ibstat查看infiniband网卡的信息：
结果：
