Conteg's TestCenter for Data Center in Pelhřimov was built especially for testing new products and their impact in different configurations on the overall data center power consumption. Computer simulations and real measurements in the laboratory allow specialists in the company to verify the principles of the various processes in the server rooms and implement innovative solutions. TC4DC is also a gathering place for experts and training specialists in the construction and maintenance of data centers. We would like to also offer our clients the premises and equipment of the experimental datacenter to test any components, and how the components might react to varying critical conditions, which are difficult and far too risky to simulate in the real operation. Finally, it offers to use premium measuring instruments both wired and wireless for testing and auditing of existing operating data centers to obtain information to optimize and to be used to promote advancements in the industry.

Basic information

  • Conteg TC4DC testing lab covers a total area of 156 m2 and consists of two rooms - experimental data center and rooms for technical support.
  • Experimental Data Center – designed as a real data center with raised floor and suspended ceiling, the area of the laboratory is 75 m2 and is separated from a technical workshop and observation area by a glass wall. Experimental room arrangement can be simulated as in real life situations. It is possible to install separate racks, their rows, contained aisles and also closed-loops.
  • Room for technical equipment – place for hardware and software to operate the center, conference room and presentation equipment.
  • Ancillary Spaces - there is a workshop area to place the hardware used for the testing and computers to run software to examine the results, along with a conference room for team meetings and technical presentations.
  • Laboratory equipment
    • Cooling system - several variable cooling options for testing different variants of traditional and experimental arrangement of ICT cabinets with thermal loading are available. There are installed two water cooled CRAC units (Computer Room Air Conditing) with the air exhaust into the raised floor and power of 80 kW each. Moreover, there are 12 position for the chilled watter connection of different versions of air-conditioning units. By default, CoolTeg units integrated into the rows of rack are offered with the cooling capacity of about 35 kW. The cooling source is two water-cooled chillers with an output of about 80 kW, one of which is equipped with free-cooling accessories. Thanks to sophisticated control, accumulation tanks, and control valves, each independent system delivers the required chilled water temperatures and flow rates. At the same time, it is also possible to accurately measure all energy flows. In addition to the water cooling system, we can also offer a compressor system with two outdoor units with a capacity of 20 kW operating with R410A refrigerant.
    • Sources of heat – the laboratory is equipped with 20 heat sources, which can be installed in 19" racks. Each source has a continuous control of air flow and regulation of the heating power of 200 W up to a total power of 6 kW.
    • Measuring instruments
      • A system of sensors for long term monitoring of quantities in the laboratory transmits information to a measuring central unit. The data is then processed and archived by specially designed laboratory software that allows the evaluation of data from individual experiments, visualization and presentation of results.
      • Independent measuring system is a system of measuring central unit and wireless temperature and humidity sensors that can be used both in the laboratory and in a real datacenter for verification of laboratory measurements in practice.
      • Separate calibrated measuring instruments for accurate verification of all local variables (sound meter, thermal imagers, anemometers, thermometers, hygrometers, CO2 sensor, pressure gauges, wattmeter, ammeter, oscilloscope, tachometer, etc.)

  • Some examples of what can be measured:

    • humidity
    • temperature (water, air, and surface of all equipment and racks)
    • air flow and water flow
    • speed of air flow and water flow
    • pressure differences in individual parts of experimental arrangements
    • CO2 concentration
    • electrical parameters (voltage, current, power consumption)
    • noise parameters
    • fan speed
