You can check the server configuration after installation. It's not compulsory but recommended.
Here are the commands for you to check the server configuration -
1. To check RAM and RAM speed - dmidecode --type 17
2. To see motherboard, cpu, vendor, serial-numbers, RAM, disks, and other information directly from the system BIOS - dmidecode | less
3. To check CPU/Hardware information - less /proc/cpuinfo or lscpu
4. To display the Linux kernel version - cat /proc/version
5. To display information about the Linux distribution and version - cat /etc/*release*
6. Check the HDD information - df -h or fdisk -l | grep '^Disk /dev/'
