1、查询cpu的相关

  a、查询CPU的统计信息

  使用命令:lscpu

  得到的结果如下:

  

Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                12
On-line CPU(s) list:   0-11
Thread(s) per core:    1
Core(s) per socket:    6
Socket(s):             2
NUMA node(s):          2
Vendor ID:             GenuineIntel
CPU family:            6
Model:                 62
Stepping:              4
CPU MHz:               2099.939
BogoMIPS:              4199.44
Virtualization:        VT-x
L1d cache:             32K
L1i cache:             32K
L2 cache:              256K
L3 cache:              15360K
NUMA node0 CPU(s):     0-5
NUMA node1 CPU(s):     6-11

  b、查询每个CPU信息  

  使用的命令:cat /proc/cpuinfo

  得到如下结果:

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

4、查看系统内核相关信息

  使用命令:uname -a

  结果:

Linux cn13 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 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:

CA mlx4_0
    CA type: MT4099
    Number of ports: 1
    Firmware version: 2.30.8000
    Hardware version: 0
    Node GUID: 0x002590fffff7761c
    System image GUID: 0x002590fffff7761f
    Port 1:
        State: Active
        Physical state: LinkUp
        Rate: 40
        Base lid: 85
        LMC: 0
        SM lid: 229
        Capability mask: 0x02514868
        Port GUID: 0x002590fffff7761d
        Link layer: InfiniBand
