A blade server is a large number of hot-swappable devices, called blades, that can be accommodated in a chassis. A server blade is a stand-alone server that includes one or more processors and associated memory, disk storage, and network controllers, and runs its own operating system and applications. 　　The blades are shared with common infrastructure components such as power supplies, fans, CD-ROM and floppy disk drives, Ethernet and Fibre Channel switches, and system ports. Using lower-energy processors in some blades can also help users save on power and cooling.
