  總結:該服務器有兩條2G內存 ,空餘4個插槽

  3 查看硬盤

  3.1 查看硬盤大小

  # fdisk -l | grep Disk

  Disk /dev/cciss/c0d0: 146.7 GB, 146778685440 bytes

  總結:硬盤大小146.7G,即廠商標稱的160G

     4 查看主板

查看主板型號:

dmidecode |grep -A16 "System Information$"

內存槽及內存條:

dmidecode |grep -A16 "Memory Device$"

五、物理機SN編號以及機型等信息

dmidecode 能夠查看不少物理機的不少信息,包含SN編號、內存、CPU、主板等若干信息,虛擬機也能夠使用該命令,可是獲取到的信息沒有物理機那麼多。

六、檢查物理機是千兆仍是萬兆網卡

ethtool eth 0 |grep Speed

ethtool bond0 |grep Speed #能夠用來檢查bond作的是否合適,合適的狀況下 獲得的網卡速率是普通速率的2倍

七、檢查電源個數

dmidecode  |grep  750W  |wc  -l  #在知道電源功率的狀況下能夠執行命令獲取電源個數
