The BladeFrame chassis, which is the size of a standard data center rack, houses the system's Processing Blades, Control Blades and Switch Blades. It also contains the built-in Egenera BladePlaneTM, which provides the physical connectivity for Processing Blade I/O, network communication and power distribution. In conjunction with the Control Blades and Switch Blades, the chassis replaces the Fibre Channel switches, Gigabit Ethernet switches and power connections required by traditional server architectures.
