Method and apparatus for preventing overloads of power distribution networks

1. A method of monitoring operation of devices in a facility, the method comprising:

controlling a plurality of computing devices in the facility to operate at a controlled power level, where the controlled power level is a predetermined percentage of a maximum power level less than 100%;

measuring air temperature at one or more locations in the facility;

controlling at least one air conditioning unit in the facility based on the air temperature at the one or more locations in the facility;

said controlling a plurality of computing devices includes controlling each of the plurality of computing devices to perform at least one additional task selected to provide a level of capacity to cause each computing device to operate at the predetermined percentage of the maximum power level.

2. The method of claim 1 , wherein measuring air temperature includes measuring air temperature at a plurality of locations in the facility.

3. The method of claim 1 , further comprising:

comparing at least one value of air temperature measured with a predetermined value to detect an over temperature condition; and

controlling at least one of the plurality of computing devices to operate in a reduced power mode upon detection of an over temperature condition.

4. The method of claim 1 , wherein each of the plurality of computing devices includes at least one peripheral device, and wherein the method further includes controlling the at least one peripheral device of each of the plurality of computing devices to operate at the predetermined percentage of the maximum power level.

5. The method of claim 1 , further comprising determining sufficiency of air conditioning of the facility based on the temperature measured.

6. The method of claim 1 , further comprising detecting a temperature outside of the facility, and determining sufficiency of the air conditioning of the facility based at least in part on the temperature outside of the facility.

7. The method of claim 1 , further comprising assigning the at least one additional task a priority level lower than other tasks being performed by the plurality of computing devices.

8. A method for evaluating cooling capability in a facility, the method comprising:

controlling at least one computing device in the facility to operate at a controlled power level, wherein the controlled power level is a predetermined percentage of a maximum power level less than 100%;

measuring air temperature at one or more locations in the facility; and

comparing at least one value of air temperature measured with a predetermined value to detect an over temperature condition;

said controlling at least one computing device includes controlling the at least one computing device to perform at least one additional task selected to provide a level of capacity to cause the at least one computing device to operate at the predetermined percentage of the maximum power level.

9. The method of claim 8 , further comprising controlling at least one air conditioning unit in the facility based on the air temperature at the one or more locations in the facility.

10. The method of claim 8 , wherein the at least one computing device includes at least one peripheral device, and wherein the method further includes controlling the at least one peripheral device to operate at the predetermined percentage of the maximum power level.

11. The method of claim 8 , further comprising determining sufficiency of air conditioning of the facility based on the temperature measured.

12. The method of claim 8 , further comprising detecting a temperature outside of the facility, and determining sufficiency of the air conditioning of the facility based at least in part on the temperature outside of the facility.

13. The method of claim 8 , further comprising assigning the at least one additional task a priority level lower than other tasks being performed by the plurality of computing devices.
