Energy efficient data centres

The digital transformation of our whole society is an ongoing progress with a lot of uncertainties regarding its outcome, especially the architecture of IT/ IoT solutions. A huge challenge of this cultural change is to deal with the flow of information between mobile humans and/or machine actors or things within or between any number of organizations, forming a value creating network with global available services. The logistic ability to collect, process and deliver data from any point to every particular user in each situation is realised by different kind of data centres spread around the world. For this reason data centres are the core of future industrial and customer services, and consequently data centres energy efficiency and sustainability a major research, business and societal problem.


6th International Workshop on Energy Efficient Data Centres

The 6th international workshop on energy efficient data centres (E2DC 2017) is an established agile platform for researchers in government, academia and industry. Our goal is to identify and emphasize cutting-edge research and to discuss how to transfer innovations from research to DC industry. As in previous years the workshop deals with data centers in ecosystems, e.g. the use of renewables, integration with smart grids, heat re-use, energy and thermal storage, etc. In addition to technical advances the workshop will also focus on approaches to increase actual adoption of energy efficient technologies in data centres, also those with traditionally low uptake. To achieve it, appropriate incentives, metrics and business models are needed. Importantly, E2DC 2017 will continue the discussion of topics from 2016, regarding the potential of specialization (IT hosting for industry production) or collaboration of DCs (like distributed or edge data centres). The workshop will also keeps on investigating energy efficiency of data centres within the context of computing disciplines such as HPC, Big data analytics, distributed applications and traditional office applications.

Call for Papers

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

  1. Energy efficient techniques for relevant emerging applications, e.g.:
    • IoT/Big Data/Deep Learning applications
    • Multimedia, augmented/virtual reality, etc.
    • Other emerging scenarios with a focus on energy savings in data centers
  2. New architectures of the whole data center ecosystems to cope with dynamic demands and requirements of data processing:
    • ○ New architectures and management of distributed data centers, edge data centers, fog computing
    • Novel approaches for data centric processing (computations closer to data)
    • Integration of data centers into existing infrastructure and facilities (e.g. buildings, wind plants and other novel locations)
    • Data center integration with smart cities, smart grids and renewable energy sources
  3. Achieving energy efficiency by the innovative use of new 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
    • Novel cooling approaches, direct liquid cooling, heat re-use, thermal storage
  4. Methods to improve uptake of energy efficient solutions in data centers, 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 centers
  5. Methods to improve energy efficiency in data centers with traditionally limited uptake of energy efficiency solutions, e.g.:
    • Energy reduction methods for colocation data centers
    • Approaches to critical infrastructures, data centers in financial domain, etc.
    • Trade-offs with availability, reliability, hardware lifetime, security


Submission and publication of the work

The workshop will be co-located with ACM eEnergy 2017 Please submit your manuscript via submission portal. Manuscripts will be published in the ACM proceedings and must adhere to ACM format (double-column sigconf 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.
