Green IT Cube

  • Innovative and energy-efficient: The "Green IT Cube" in the form of a cube measuring 27×30×22 m with six floors and an adjacent technical building including cooling towers.
  • In the first version, the Green IT Cube has a cooling capacity of 4 megawatts, which will rise to 12 megawatts in the final expansion phase. The water cooling used in the rear doors of the server cabinets is highly efficient and requires less than 7% of the electrical power of the IT equipment.
  • It houses a mirror (RZ-1 and Green IT Cube) of the important basic IT services, as well as the servers, computing nodes and storage units for the experiment data.
  • A time-lapse video about the construction of the Green IT Cube can be found here:
  • KPI for the Green IT Cube in 2023:
    PUE 1.08
    WUE 1.8
    CER 16.38


  • Conventional data center with the central network node, mirror data center for the important basic services, and central location of the magnetic tape library.
