Lowering data centre power consumption.

While the world is becoming ever more digital and developing strategies for handling AI, it’s only getting clearer that it’s also just as urgent, if not more, to separate the growth in data centre power consumption from the growth in computing power. Of course, there it will still have some bearing, but operators already have several levers at their disposal to make data centres more energy-efficient and future-proof. We present the key five.

Server consolidation.

Outdated, inefficient servers are replaced by modern, high-performance systems that offer more computing power per rack unit thanks to better integration and higher density. This consolidation lets you achieve the same workloads with fewer physical servers, drastically lowering your server power consumption as well as cooling and space requirements.

Hot and cold aisle containment.

Physical separation of cold inlet air from the hot output air zones prevents them from mixing, with flexible containment systems ensuring strict division of hot and cold aisles. This optimised airflow management reduces energy requirements for air conditioning compared to traditional layouts with no costs for cooling mixed air and higher inlet air temperatures are allowed.

Liquid cooling of server components.

Cooling is performed by direct contact between a cooling liquid and the server components instead of through the air. The liquids have a far higher thermal capacity than air and can therefore more efficiently discharge excess heat, in turn drastically reducing energy requirements for cooling.

Intelligent load management.

Software systems analyse use patterns and predict the resources required to ramp or down servers and optimally distribute workloads. The combination of real-time monitoring and predictive analyses allows load peaks to be reduced while also keeping the active server in the optimal efficiency range.

Heat recovery.

The waste heat from the servers is not simply released into the environment, but used by heat exchangers for heating or in industrial processes. Integration into local heating networks means that the majority of the waste heat from the servers can be reused which drastically increases overall energy efficiency.
