Hi all,

I only know that a rack server, also called a rack-mounted server, is a computer dedicated to use as a server and designed to be installed in a framework called a rack. While, a blade server is a stripped-down server computer with a modular design optimized to minimize the use of physical space and energy. As, I find both blade and rack-mounted servers offer distinct advantages in data center computing. I am so excited to know the basic difference between Rack & Blade Server. Any idea much appreciated.

I didn't find the right solution from the internet.
