Embodiment Construction

[0009] In any computer system, the processor complex will typically be the largest consumer of power. This power consumption is direct in the sense that the workload executing on the processor requires the processor to consume power, and as the workload demands increase, so does the processor power consumption. Power consumption is also indirect, as increased processor demand may increase memory and peripheral usage, and will generate more heat, requiring increased cooling system operation.

[0010] Power consumption in the processor complex can be controlled or reduced by reducing the core frequency of the processor (eg, reducing the core frequency from 3.0 GHz to 2.0 GHz). Power consumption can also be reduced by controlling the average effective frequency of the CPU clock. To achieve power control using frequency and CPU clock control mechanisms (sometimes referred to as CPU down-clocking), the processor complex may install software routines that monitor processor power co...

Abstract

A system, and a corresponding method, for temporarily capping power consumption includes a mechanism for determining total power consumption by a number of components, a mechanism for disconnecting and reconnecting power to one or more of the components, and a mechanism for determining when to disconnect and reconnect power to the components.

Description

technical field [0001] The present invention discloses a power capping system and method for temporarily capping power consumption in a computer system. Background technique [0002] Computer systems can draw considerable amounts of power from their associated power supplies. In some cases, the workload executing on the computer system may place such demands on the computer system's processor that the power rating of the power supply is exceeded. Exceeding rated power increases the heat output of the computer system, with consequential demands on the computer system's cooling infrastructure and possible damage to computer system components. Exceeding rated power may also cause unexpected loss of computer system components, such as by tripping a circuit breaker. Contents of the invention [0003] The present invention provides a power capping system for temporarily capping power consumption in a computer system having a plurality of components including at least one power...
