Each blade is a bundle of hardware packaged onto a single flat unit that can be quickly slotted into and removed from a computer rack.

Vendors argue blades are more energy efficient than traditional options.

Blade PCs also reduce the office temperature as the heat produced by the blades is restricted to the computer room - resulting in a more comfortable working environment, as traders at Lloyds TSB found out.

The University of Reading is also using a blade-based system in its supercomputer which will, quite appropriately, be working on research including air pollution, climate change and meteorology.
