First Claim
1. A computer system having at least one processing element and at least two power supply elements operable to provide redundant power supply for the at least one processing element, the processing element being configured to consume more power than is provided by the power supply capability of one of the power supply elements at a time when redundant power supply is available, and to limit its power consumption to the power supply capability of one of the power supply elements when redundant power supply is not available.

Abstract
A computer system is provided having at least one processing resource, at least one power resource and at least one redundant power resource. The at least one processing resource is operable to exploit a greater level of power than is provided by the at least one power resource. The at least one processing resource is configured to exploit power provided by both the at least one power resource and the at least one redundant power resource, at a time when both the at least one power resource and the at least one redundant power resource are both operable to provide power. The at least one processing resource is further configured to limit its power consumption to the power supply capability of one of the power resource and the redundant power resource when one of the power resource and the redundant power resource is not available

19. A computer system having at least one processing means for performing a processing task and at least two power supply means for providing redundant power supply for the at least one processing means, the processing means being configured to consume more power than is provided by the power supply capability of one of the power supply means at a time when redundant power supply is available, and to limit its power consumption to the power supply capability of one of the power supply means when redundant power supply is not available
-
20. A computer system operable to receive redundant power supply, wherein the computer system is operable to exploit additional power provided by the redundant power supply at a time when the redundant supply is available and to limit power exploitation to available power when the redundant supply is not available.
-
21. A method of exploiting redundant power provided to a programmable processing apparatus, the method comprising:
-
detecting an operational status of each of a plurality of power supplies to the programmable processing apparatus to determine a redundancy availability result;
permitting the programmable processing apparatus to utilize more power than is available in the event of a negative redundancy availability result upon a determination of a positive redundancy availability result; and
limiting the power utilization of the programmable processing apparatus to the power that is available in the event of a negative redundancy availability result upon a determination of a negative redundancy availability result.
-
- 22. A computer system having at least one processing resource and at least one power resource and at least one redundant power resource, wherein the at least one processing resource is operable to exploit a greater level of power than is provided by the at least one power resource, the at least one processing resource being configured to exploit power provided by both the at least one power resource and the at least one redundant power resource at a time when both the at least one power resource and the at least one redundant power resource are both operable to provide power.
-
26. A computer system comprising a plurality of processing elements, at least one power supply element, and a computer system management element operable to interrogate each of the plurality of processing elements to determine a current power consumption for each of said plurality of processing elements, to compare each said current power consumptions to a current maximum allowable power consumption for the respective processing element to obtain a power comparison result, and to instruct selected ones of said plurality of processing elements to increase or decrease their power consumption in accordance with said power comparison result.
