Budgeting for power consumption in a chassis environment that includes a plurality of integrated technology elements
Methods, apparatuses, and products 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, including: 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.
1. A method of 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 method comprising:
determining, by a chassis management module, a total power requirement value based on a sum of the average power consumption for each ITE;
determining, by the chassis management module, a system power utilization delta in dependence upon system configuration information describing one or more components in the chassis environment including an amount of time required to power on an additional power supply, wherein the system power utilization delta represents an amount of additional power that can be allocated for use by the ITEs;
increasing, by the chassis management module, the total power requirement value in dependence upon the system 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 increased total power requirement value; and
powering on the identified one or more power supplies by the chassis management module.
2. The method of claim 1 further comprising powering off each of the power supplies that were not identified to provide power to the ITEs in the chassis environment.
3. The method of claim 1 further comprising rotating, by the chassis management module, which power supplies are identified to provide power to the ITEs in the chassis environment in dependence upon a power supply management policy.
4. The method of claim 1 wherein each of the power supplies has an identical power delivery rating and identifying the one or more power supplies to provide power to the ITEs in the chassis environment further comprises identifying a number of active power supplies in dependence the power delivery rating and the total power requirement value.
5. The method of claim 1 further comprising powering on one or more additional power supplies in dependence upon a predetermined power mode.
