Energy efficient data centres

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.

10th International Workshop on Energy Efficient Data Centres (E2DC 2022)

The necessary scientific dialogue was and is the DNA E2DC 2022 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. In addition to the focus on energy informatics, we specifically welcome interdisciplinary works.

Call for Papers

The workshop invites original papers up to 6 pages that were not published before and are currently not under consideration and/or review for publication elsewhere. Topics include, but are not limited to:

  1. Innovative or improved architectures optimizing the data centre ecosystems to cope with dynamic demands and requirements of large service platform ecosystems:
    • Data centre integration with smart cities, smart grids and renewable energy sources
    • Modular DCs, Multicore Infrastructure DCs, DC Life Cycle Management
    • Best practices for sector coupling or symbiotic integration of data centres infrastructure into existing facilities (e.g. buildings, wind plants and other novel locations)
    • Novel cooling approaches, direct liquid cooling, heat re-use, thermal storage
  2. Achieving energy efficiency by the innovative use of new hardware and software technologies, e.g.:
    • Microservers, low power CPUs, embedded SoCs
    • Methods to facilitate the use of hardware accelerators at large scale, the use and integration of heterogeneous systems
    • Virtualization and service architectures, containers, lightweight virtualization, microservices
    • Approaches for application centric and distributed/on the fly processing of data and information
    • New architectures and management methods for distributed data centres, edge data centres, fog computing and edge computing
  3. Methods to improve uptake of energy efficient solutions in data centres, incentives that increase focus on energy efficiency and reduction of emissions:
    • New business models and programs to make the use of energy efficient technologies profitable
    • Metrics beyond PUE
    • Green and energy-related SLAs
    • Engaging end users in limiting energy consumption and carbon footprint
    • Other incentives leading to increased adoption of energy efficient technologies in data centres
  4. Execution environments for and application of AI/ML:
    • Specialized DC architectures adapted to the IT systems executing AI application or platforms
    • Innovative application of AI using forecast, anomaly detection, clustering or predictive maintenance to obtain or gain sustainability and resource efficiency
    • AI optimized dc management of complex infrastructures and subsystems
    • Innovative application of AI like forecast, anomaly detection, clustering or predictive maintenance to obtain or gain sustainability and resource efficiency
    • Automated AI feature extraction for e.g individual key performance indicators or data center metrics for comparisons
    • AI based resource purchasing and procurement strategies
    • Automated anomaly detection and predictive maintenance optimizing risk managemt
    • AI based operation unlocking potential of demand response programs
    • Multi-criteria selection of configuration for trade-off between performance, efficiency, and gains from interaction with other stakeholders (e.g. smart grids, heat operators, consumers of heat, etc.)

Submission and publication of the work

The workshop will be co-located with ACM eEnergy 2022 Please submit your manuscript via submission portal. Manuscripts will be published in the ACM proceedings and must adhere to ACM format. Submission implies the willingness of at least one author to register and present the paper at E2DC. The organizers reserve the right to exclude a paper from publication if it is not presented.

Title: Evolution of Sustainable Digital Infrastructures - The role of Datacentres and Innovaters for waste heat usage in Frankfurt

Speaker: Dr. Béla Waldhauser, Telehouse Deutschland GmbH

In this presentation Dr. Béla Waldhauser, Telehouse Deutschland GmbH, will explain his perspective on the past decades of sustainability evolution in the data center business. He will describe challenges discovered during digital transformation of the facility side of data centers. He will show us the impact of increased pressures by energy costs and the effort made to overcome the waste of thermal energy. This he will present a current Telehouse Germany project that re-uses/ delivers waste energy to supply households in Frankfurt, Germany - the major spot of data center waste heat dissemination in Germany.

Title: Intelligent sustainable energy systems

Speaker: Prof. Dr. Henning Meschede, KET, University Paderborn

There is a need for a digital perspectives on energy systems. Sustainable energy supply is a necessary prerequisite for distributed sustainable high performance computing data centers. We need to understand the supplier to unlock the potential of an adaptive consumer - like distributed HPC data centres.
