Getting hardware information from a server that you've never laid eyes on, is thousands of miles away and can physically access is sometimes difficult.
Below are some items that I've used in the past to get details of the hardware in the system. You can harmlessly type the commands in as they only inspect info and do not change anything.
dmidecode
I like this one. It gets the info from the bios, even the product name, serial number and Dell service tag number. It even gets the BASEBOARD info (or motherboard info) and the CHASSIS info (the actual physical case) with it's locked status.
The full is is:
- dmidecode
- lspci
- lsusb
- df -h
- fdisk -l
- mount | column -t
- cat /proc/cpuinfo
- cat /proc/meminfo
- cat /proc/scsi/scsi
- cat /proc/version
- uname -a
- cat /proc/partitions
