Energy efficient data centres

In 2020, due to the corona crises, digital infrastructures have provided indispensable added value for the cohesion of our society. As a substantial component of this infrastructure, data centers perform the primary digital work and act reliably in the background, broadly unnoticed since decades. Undeniably, the reliability of nowadays data centers, the flexibility of digital processes, their joint resilience against unforeseen has accelerated the transformation to digital ways of living and working. On the one hand, this new digital area has led to a reduced environmental impact due to changes in mobility and other behavioural constraints; on the other hand, it has generated increased demands for existing data center capacities and data center construction. Ultimately and again, this growth will lead to increased demands for resources such as electricity and emissions such as waste heat and electronic or construction waste. The economic pressure of is growth offers also an opportunity to show up with new innovative demand oriented data center architectures and holistic solutions, devoted to non-functional requirements and values of our society like sustainability and resource efficiency.


9th International Workshop on Energy Efficient Data Centres (E2DC 2021)

The necessary scientific dialogue was and is the DNA E2DC 2021 workshop. It studies innovative methods to improve energy-efficiency and sustainability of all imaginable data centre variations. Importantly, E2DC regards a broader context of data centre ecosystem by investigating its integration and interactions with smart grids, smart cities and energy intense applications or platform ecosystems. A wide spectrum of topics ranging from the use of renewable energy over the control and optimisation of infrastructure services and emissions, demand response techniques to federation of distributed data centres.

This year, beside established topics, we will discuss the impact of Artificial Intelligence and Machine Learning (AI/ML) on data centers. This technology can help to improve data centers in all areas, where mastering an increased system complexity results into higher efficiency, less emissions, more automation or better integration. This technology will foreseeably need optimized data center architectures and, analogous to the HPC data centers, challenge the one fits all concept and demand specialized variations. In addition to the focus on energy informatics, we specifically welcome interdisciplinary works.
