Customized power rating for computer equipment

摘要

A mechanism is provided for customized power rating for computer equipment. A power monitor determines actual power consumption by computer equipment in a facility. After equipment has been stressed, an operator sends the actual power consumption information to the manufacturer. The manufacturer receives the actual power consumption information and issues a certificate that acknowledges the equipment will not consume more power than what was measured. The manufacturer may provide digital media that instructs power management hardware in the computer equipment to adhere to an actual case power limit. The power management hardware treats the actual case power limit as a hard power limit. That is, the power management hardware will not specify a power cap higher than the actual case power limit. The power management hardware prevents the equipment from crossing the actual case power limit.

主权项

1. A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a processor, causes the processor to:
receive a default power limit for a computer device; record actual case power consumption for the computer device based on an actual configuration and workload of the computer device; apply an actual case power limit to the computer device, wherein the actual case power limit is determined based on the recorded actual case power consumption; responsive to a customer reconfiguring the computer device to form a new configuration, record new actual case power consumption for the computer device based on the new configuration and workload of the reconfigured computer device; determine whether the reconfigured computer device operates within the actual case power limit; and responsive to the reconfigured computer device not operating within the actual cased power limit, apply a new actual case power limit to the reconfigured computer device, wherein the new actual case power limit is determined based on the recorded new actual case power consumption.
