How To Find Server or Desktop Hardware Information on Linux

If you need to know what hardware your desktop or server has without having physical access to the machine, you can look it up using a linux command called dmidecode.

A couple of days ago I had to find out the product and model of my Dell server. I knew it was an Dell PowerEdge but didn’t know if it was a R230, R240, R340 or R440. By using dmidecode we extract following information:



[root@labserver /]# dmidecode --type 1

# dmidecode 2.10
SMBIOS 2.3 present.

Handle 0x0100, DMI type 1, 25 bytes
System Information
Manufacturer: Dell
Product Name: PowerEdge R240
Version: Not Specified
Serial Number: xxxxxxxx
UUID: xxxxxxxx
Wake-up Type: Power Switch

The command has several options you can use with dmidecode to collect all the information you want. Just take a look at the following:
