Blade server

Blade servers are computer servers arranged for high-density installations, such as data centers. Rather than using an AT-style form factor in a single-PC case, multiple independent processors, and sometimes disks and communications interfaces, slide into a multiple-slot chassis that bolts into an industry-standard 19" wide rack.

To deal with the concentrated heat load, the chassis is designed for efficient cooling, which can be forced air, or chilled water pumped through pipes.
