Need to understand concept and configuration of blade server

A blade server is a stripped-down server computer with a modular design optimized to minimize the use of physical space and energy. Whereas a standard rack-mount server can function with a minimum of a power source and a network connection, blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer.Unlike a rack-mount server, a blade server needs a blade enclosure, which can hold multiple blade servers, providing services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form a blade system. Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system as a whole.
