Method and system for powering multiple computer platforms in symmetric configuration

摘要

Techniques pertaining to powering multiple platforms with a minimum impact on air passage in a predefined environment are disclosed. Instead of connecting each of the platforms in a chassis to a power supply therein, the present invention uses what is referred to as cascading powering to power all platforms within minimum cable delivery. According to one embodiment of the present invention, a power supply is disposed between two groups of platforms and powers them at the same time. At least one of the platforms has a power connector located towards or near the power supply so that only a short cable is needed to power the platform.

主权项

1. A method for powering multiple mother boards in an enclosed computing environment, the method comprising:
connecting a first short cable to a power distribution board included in a power supply unit and to a first mother board to couple the first mother board immediately adjacent to a first side of the power supply unit, wherein the first short cable is configured to transfer power at different voltage levels as well as control signals from the power supply unit to the first mother board; and connecting a second short cable to the power distribution board and to a second mother board to couple the second mother board immediately adjacent to a second side of the power supply unit that is opposite to the first side of the power supply unit, and wherein the second short cable is configured to transfer power at different voltage levels as well as control signals from the power supply unit to the second mother board.
