Multi-server and multi-CPU power management system and method
First Claim
1. In a computer system including at least one processing unit, a memory coupled to said at least one processing unit, and logic circuits coupled to said processing unit contributing to operation of said computer system, a method for controlling the operating mode and as a result the power consumption of said computer system between a plurality of operating modes each having a different electrical power consumption levels or ranges;
- said method comprising;
while operating in a first selected operating mode exhibiting that first selected mode'"'"'s characteristic power consumption range, (i) monitoring said computer system to detect the occurrence or non-occurrence of a first event; and
(ii) transitioning said computer system from said first selected operating mode to a second selected operating mode exhibiting that second selected operating mode'"'"'s power consumption range.

Abstract
Network architecture, computer system and/or server, circuit, device, apparatus, method, and computer program and control mechanism for managing power consumption and workload in computer system and data and information servers. Further provides power and energy consumption and workload management and control systems and architectures for high-density and modular multi-server computer systems that maintain performance while conserving energy and method for power management and workload management. Dynamic server power management and optional dynamic workload management for multi-server environments is provided by aspects of the invention. Modular network devices and integrated server system, including modular servers, management units, switches and switching fabrics, modular power supplies and modular fans and a special backplane architecture are provided as well as dynamically reconfigurable multi-purpose modules and servers. Backplane architecture, structure, and method that has no active components and separate power supply lines and protection to provide high reliability in server environment.
