Budgeting for power consumption in a chassis environment that includes a plurality of integrated technology elements

An apparatus for budgeting for power consumption in a chassis environment that includes a plurality of integrated technology elements (‘ITEs’), each ITE having power utilization information indicating an average power consumption of the ITE, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

• determining, by a chassis management module, a total power requirement value based on a sum of the average power consumption for each ITE;
• increasing, by the chassis management module, the total power requirement value in dependence upon a predetermined power utilization delta;
• identifying, by the chassis management module, one or more power supplies to provide power to the ITEs in the chassis environment in dependence upon power delivery capabilities of the one or more power supplies and the total power requirement value;
• and
• powering on the identified one or more power supplies by the chassis management module.

A computer program product for budgeting for power consumption in a chassis environment that includes a plurality of integrated technology elements (‘ITEs’), each ITE having power utilization information indicating an average power consumption of the ITE, the computer program product disposed upon a computer readable medium, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:
