Energy efficient data centres

Data centres are the core of future industrial and customer services, especially taking into account a fast development of clouds, mobile applications, Internet of Things (IoT) and artificial intelligence (AI) techniques. Consequently data centres energy efficiency and sustainability has becone a major research, business and societal problem. To address this problem the main goal of the E2DC 2018 workshop is to study innovative methods to improve efficiency and sustainability of data centres - important and ever growing source of energy consumption.

7th International Workshop on Energy Efficient Data Centres

Importantly, E2DC concentrates on a broader context of data centre ecosystem by investigation of interactions with other data centres, smart cities and smart grids. Hence, the workshop discusses topics such as the use of renewable energy, optimisation of cooling and heat re-use, demand response techniques, federation of distributed data centres and many more. This year, in addition to these general workshop topics, we would like to discuss the future trends of data centre development, especially their architectures and location. We would like to discuss whether a majority of data centres will be concentrated in large colocation data centres and public clouds or if (and how) smaller systems can be integrated with existing infrastructure (e.g. buildings, homes, wind power plants, etc.).

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. New architectures of the whole data centre ecosystems to cope with dynamic demands and requirements of large data processing:
    • New architectures and management methods for distributed data centres, edge data centres, fog computing
    • Novel approaches for data centric processing (computations closer to data)
    • Integration of data centres into existing infrastructure and facilities (e.g. buildings, wind plants and other novel locations)
  2. Achieving energy efficiency by the innovative use of new hardware and software technologies, e.g.:
    • Microservers, low power CPUs, embedded SoCs, modular DCs
    • 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
  3. 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

Submission and publication of the work

The workshop will be co-located with ACM eEnergy 2018 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: The 4 Es of Edge Data Centers

Speaker: Jon Summers (Scientific Leader in Data Centres, Research Institutes of Sweden, Swedish Institute of Computer Science (RISE SICS) North)

Abstract: For more than 10 years the data center sector has been improving its End use Energy demand in the face of unprecedented growth by using metrics that focus not on Efficiency, but Effectiveness. The trend to centralise processing and data into the cloud, which does offer most the Economy of scale, is developing a data center ecosystem that is centralised around megascale core data centers. However, the elements (humans and machines) that interact with these large scale data centers are distributed and more and more require data to be everywhere and in particular nearby. In a parody of the Vs of Big Data, this presentation will make use of as many technical and scientific facts as possible to reflect on the potential Es of Edge of network data centers, which may become the Effective Economic Energy-Efficient Exergetic infrastructure of the future.
