Abstract
An information processing system may comprise an electronic circuit comprising a primary circuit board of the information processing system, at least two power supplies providing electrical energy to the electronic circuit according to a power sharing ratio, with each power supply being cooled by a set of fans, and a controller, coupled to the set of power supplies and the set of fans. The controller detects a failure of one of the fans and adjusts the power sharing ratio from a default ratio to an adjusted ratio in response to detecting the failure of the one fan.
Claims20
A method comprising:
- providing cooling to at least two power supplies in an information processing system, the cooling provided to each of the at least two power supplies by a set of fans, the power supplies supplying electrical energy to an electronic circuit according to a power sharing ratio, the electronic circuit comprising a circuit assembly of the information processing system;
- detecting a failure of one of the fans;
- and
- adjusting the power sharing ratio from a default ratio to an adjusted ratio in response to detecting the failure of the one of the fans.
The method of claim 3, wherein the characteristic is a droop curve associated with the power supplies.
An information processing system comprising:
- an electronic circuit comprising a primary circuit board of the information processing system;
- at least two power supplies, each power supply providing electrical energy to the electronic circuit according to a power sharing ratio, each power supply being cooled by a set of fans;
- and
- a controller, coupled to the set of power supplies and the set of fans, the controller detecting a failure of one of the fans and adjusting the power sharing ratio from a default ratio to an adjusted ratio in response to detecting the failure of the one of the fans.
A non-transitory machine readable medium storing an operating image comprising instructions that, when executed by at least one processor in an information processing system, causes the system to:
- detect a failure of one of a set of fans, the set of fans providing cooling for at least two power supplies supplying electrical energy to an electronic circuit according to a power sharing ratio, the electronic circuit comprising a primary circuit for the information processing system;
- and
- adjust the power sharing ratio from a default ratio to an adjusted ratio in response to detecting the failure of the one of the fans.
