Unified Chassis Management—Topological Zone-Based Cooling

Disclosed is a method that uses multiple temperature sensors and fans to cool specific zones of a chassis. Benefits include the ability to recover efficiently and effectively from a failure condition. 

Background

In current designs, if there is an increase in temperature in a section of the chassis, all fans are indiscriminately sped up to help cool the chassis.

General Description

The disclosed method divides a chassis into zones, each of which has a temperature sensor and a set of fans. If the sensor in a particular zone perceives an increase in temperature, the speed of the first fan in that zone is increased; if the first fan does not cool off the zone, the speed of subsequent fans is increased until the zone of the chassis is cooled (see Figure 1).

Temperature sensors are mapped to the appropriate fans in topological areas via a configuration file. Also, fans are weighted so that the closest fan is the first to provide the necessary cooling.

Advantages

The disclosed method effectively targets the areas of the chassis that may need cooling, thereby helping the chassis recover efficiently from a failure condition.
