Title: NRG meeting: Temperature Management in Data Centers: Why Some  
(Might) Like It Hot

The energy consumed by data centers is starting to make up a significant  
fraction of the world¹s energy consumption and carbon emissions. A large  
fraction of the consumed energy is spent on data center cooling, which has  
motivated a large body of work on temperature management in data centers.  
Interestingly, a key aspect of temperature management has not been well  
understood: controlling the setpoint temperature at which to run a data  
center¹s cooling system. Most data centers set their thermostat based on  
(conservative) suggestions by manufacturers, as there is limited  
understanding of how higher temperatures will affect the system. At the  
same time, studies suggest that increasing the temperature setpoint by just  
one degree could save 2­5% of the energy consumption.

This paper provides a multi-faceted study of temperature management in data  
centers. We use a large collection of field data from different production  
environments to study the impact of temperature on hardware reliability,  
including the reliability of the storage subsystem, the memory subsystem  
and server reliability as a whole. We also use an experimental testbed  
based on a thermal chamber and a large array of benchmarks to study two  
other potential issues with higher data center temperatures: the effect on  
server performance and power. Based on our findings, we make  
recommendations for temperature management in data centers, that create the  
potential for saving energy, while limiting negative effects on system  
reliability and performance.
