Как получить информацию о железе используя dmidecode

Administration

Узнаем информацию об аппаратной части сервера используя интерфейс DMI(Desktop Management Interface).

Dmidecode - утилита для Linux, позволяющая работать с DMI, которая выводит информацию об:

  • bios
  • system
  • baseboard
  • chassis
  • processor
  • memory
  • cache
  • connector
  • slot

Установка

Установим dmidecode.

Debian/Ubuntu
apt-get install dmidecode
RHEL/Centos
yum install dmidecode

Получаем информацию.
