Siemens to equip Deutsche Telekom's largest data center


Siemens' Low and Medium Voltage Division will install power distribution technology in a new data center operated by Deutsche Telekom in Biere, Germany.

The company will also supply power distribution technology for the existing twin data center in Magdeburg. The order covers the delivery of medium and low voltage switchgear, transformers, building control technology and busbar trunking systems.

Secure power supply and distribution is crucial for maximum equipment availability. With a server footprint of more than 5,600 square meters and a power demand of approximately 120 megavolt amperes (MVA), the data center in Biere is expected to be one of the largest in Germany after all expansion stages have been completed. Commissioning is scheduled for the spring of 2014.

The data center in Biere, 30 kilometers south of Magdeburg, will be built by a group of companies. T-Systems, a subsidiary of Deutsche Telekom, will lease and regularly modernize the data center once it is complete. The new building is intended to form a twin data center with an existing data center in Magdeburg.

All files and programs will thus be saved in parallel, especially for cloud applications. If one data center fails, the twin center will jump in, which will increase failure tolerance. After the building is completed, a total floor area equal to nearly eight soccer fields, including the IT areas for the computer systems, will be available in both locations. A data center consumes enough electricity to power a small city.

To maintain safe, comprehensive power distribution within the data centers, Siemens will supply a 30-kV NXPLUS gas-insulated medium voltage switchgear with eight fields as well as  20/10-kV NXPLUS C gas-insulated medium voltage switchgear with a total of 78 fields, including the protective systems, Along with the 8 Geafol transformers, (2,500 kVA, each), Siemens will also supply the Sivacon 8PS busbar trunking system. The busbars measure a total of 4,200 meters in length. The Sivacon low-voltage switchgear (540 fields) will be supplied by Siemens' franchise partner ESA Grimma.

A power outage of no more than 10 milliseconds can cause massive disturbances in data center systems. Siemens power distribution system are designed specifically for the high demand of data centers. They meet maximum standards of security and efficiency.

Thanks to their design, busbars are especially suitable for data centers since they are particularly robust and take up very little space. They also have a lower fire load compared to cables. The busbars can be easily upgraded when the data centers are expanded; their connections can be varied flexibly and at low cost.

The rapid growth in IT-assisted business processes worldwide is generating enormous volumes of data, which requires more and more storage space and server capacity for processing. Data centers throughout the world provide this storage space and make it available as a "cloud." In cloud computing, files or applications are no longer stored on a fixed computer but are located on servers in data centers, where they can be accessed from all over the world.

A supply of electricity is essential for operating data centers and the servers, network components and data lines they contain. A reliable supply of electricity must be available not only for the IT but also for infrastructure functions such as cooling and air conditioning, fire monitoring and firefighting, security and control, lighting, elevators, drives and motors.

Im Focus: Kick-off for a new era of precision astronomy

The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.

As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...

Im Focus: Locusts at the wheel: University of Graz investigates collision detector inspired by insect eyes

Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.

In cooperation with the Center for Nano-Optics of Georgia State University in Atlanta (USA), scientists of the Laboratory for Attosecond Physics of the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität have made simulations of the processes that happen when a layer of carbon atoms is irradiated with strong laser light.

Electrons hit by strong laser pulses change their location on ultrashort timescales, i.e. within a couple of attoseconds (1 as = 10 to the minus 18 sec). In...
