Optimizing efficiency and power density in mainframe systems often comes with a trade-off in design flexibility. A 380VDC architecture for 'big iron' with loads of 100s of amps at <1V is unlikely to be optimal powering 'plug and play' rack-mount server motherboards. Factorized Power Architecture (FPA) is a power component building block approach which can scale up for high power with high distribution & conversion efficiency, yet is flexible to enable lower power systems to utilize the energy saving benefits and maximize processing performance per rack. Using 48V to drive processor/memory domains while providing 12V power for legacy loads (drives, I/O, etc.), FPA presents the optimal solution of efficiency, power density and flexibility for high power custom servers and lower power 'off the shelf' server configurations. The 'pure powertrain' solution is processor & controller 'agnostic', running in any analog or digital system so mixed-core / cluster systems are easily driven.
