A server architecture that houses multiple server modules ("blades") in a single chassis. It is widely used in data centers to save space and improve system management. Either self-standing or rack mounted, the chassis provides the power supply, and each blade has its own CPU and memory. Redundant power supplies may be an option. Blade servers generally provide their own management systems and may include a network or storage switch.

A PC structure that includes multiple PC modules ("blades") in a single chassis. It takes the machines off the users' desks and houses them in rack mounted cabinets in remote location similar to blade servers. The user's keyboard, monitor and mouse plug into a device at the desk that is wired via a TCP/IP or direct connection to the assigned blade in the data center.

Having the physical PCs in the data center reduces noise and heat at users' desks and takes advantage of the inherent security in a locked room. PCs cannot be pilfered from cubicles, and data cannot be uploaded or downloaded because there is no access to USB ports and drives.

Instead of a hardware relocation, moving a user to a new station requires only an adjustment to the management software. If a PC fails, a spare blade may be available in each chassis for hot swapping, which is also a software function. In addition, repairs are always performed in the same place, and technicians do not have to travel throughout the building.
