Blade Server: Rationalize computers

Blade servers are based on the idea of operating several computers on a single power supply, on a single shared storage medium and with a single ventilation system. This saves space, energy and simplifies the system architecture.

The boards with the microprocessors and RAM are pushed into the server side by side like 'blades'. Today, the standard rack accommodates more than 80 such blades, i.e. far more than 5,000 processors. The main advantages are the compact design, high power density, scalability, simple cabling and quick and easy maintenance.

However, the energy design and ventilation of this 'high-density computing power' requires a great deal of technical expertise, which is why small and medium-sized enterprises (SMEs) in particular are increasingly outsourcing such tasks to external companies.
