在linux中查詢硬體相關信息

1、查詢cpu的相關

　　a、查詢CPU的統計信息

　　使用命令：lscpu

　　得到的結果如下：

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

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、查詢每個CPU信息　　

　　使用的命令：cat /proc/cpuinfo

　　得到如下結果：

5、利用dmindecode查看硬體信息

查看伺服器型號
dmidecode | grep 'product name'
查看主板序列號
dmidecode | grep 'Serial Number'
查看系統序列號
dmidecode -s systems-serial-number
查看記憶體信息
dmidecode -t memory
查看oem信息
dmidecode -t 11

**6、利用ibstat查看infiniband網卡的信息：
