Datacenter Cooling


CapTherm Datacenter CoolingCooling the worldwide base of installed servers is an enormous challenge! Ever-increasing performance and the requirement for smaller form factors have led to major increases in heat density.  Traditional cooling methods are unable to handle such densities effectively. CapTherm’s multiphase system is the next generation solution ready to solve this problem and, concurrently, reduce energy consumption and the emissions of greenhouse gases.

Sector Context:

In 2010, the cost for powering and cooling the worldwide server base was at about $43bn, with cooling accounting for 30% or $12.9bn of that figure.

To put the energy consumption of worldwide datacentres into perspective, the global energy requirements for data centers equalled 1.5x the energy requirement to power New York City. Datacentres are responsible for about 2% of global carbon emissions and use 80 million megawatt-hours of energy annually. If the current growth rate were to continue, without improving energy efficiency, datacentres will produce 359 megatons of CO2 by 2020 (equivalent to the CO2 produced by 48% of the cars estimated to be on American roads at that time).

From 1998 to 2007 server performance has increased 75x while the performance per watt has increased 16x. This implies that, for every watt consumed, the consumer is getting 16x the throughput that they got in 1998. Roughly speaking, the performance/Watt of a server doubles every 2 years. This steadily increasing performance requires increasingly greater power capacity. The trend toward virtualization, the growth of applications like video streaming, and the massive expansion of social media have all contributed to a massive demand for higher-performing machines.

Traditionally, every watt of power devoted to computer processing in datacentres required a half watt of power for cooling and lighting. This ratio has now flipped: Every watt consumed by computing resources now requires two watts of power for cooling and lighting. The result is that, even though global spending on servers has increased on an almost linear basis over the past 15 years, we have seen a dramatic increase (400%) in spending on power and cooling over the same period.
