To Determine System Configuration - (No of CPUs, their speed, RAM, No of Hard disks, their capacity).

[unix syzadmin]

Hi,

We have a lot of RedHat Linux servers in our lab.  I have been assigned a
task to determine hardware configuration of these servers.  Please suggest
some commands that would give the following information:
1. Type and No of CPU's, also their speed,
2. Amount of RAM.
3. No of Hard disk and their size.

Thanks & Regards,
