Please ping if any single command that will show a server hardware specs in centos (Like how many processor, how many cores , how many cache inside, how many installed RAM is there, how many pci-e slots inside, how many usb ports like this.)
Hi actually there are lot of commands to get the h/w specs, try dmidecode it will reports information about your system’s hardware as described in your system BIOS.
DMI Type id will give information about a particular hardware component of your system
For ex:
# dmidecode -t 1

1 is the id wchic will shows you the info about System Information
and also try the below command to get the details of your system h/w specs
