Marecon's partner e3Computing wins Start Green Award 2015
November 23, 2015
Last week StartGreen anounced the winners of the Start Green Awards 2015. Marecon's partner e3Computing was the winner in the category Start-ups. In close cooperation with our partners Deerns Consulting Engineers and TTSP HWP Seidel e3c developed the revolutionary way of cooling data centres: the Cube concept.
The criteria for nomination were not only based on the ecological advantages of the services. Only real innovations were selected - a 100 in total - that could serve as an example for the Green founder community in Germany. The StartGreen institute supports founders and entrepreneurs of green start-ups and encourage them to form a Green network.
The Cube Concept
The Cube concept is a different way of cooling data centers. The servers are cooled through passive rear rack doors and hence the servers make their own cold air. There are no CRAC units or other fans in the data center required to maintain the ASHREA standard conditions. The cooling system chilled water is distributed via piping working according to the Tichelman principle, eliminating the need for regulating valves. One combined set of piping is installed per two floors of white space in principle to further improve the cost effectiveness.
It allows for low PUE and can be combined with various cooling technologies for cooling the water including free cooling or natural water reservoirs. Concept is scalable and can be used in existing buildings or green field. This technology allows for standard cost effective solution for high-density racks, cloud, low density in the same rack row without any additional tailor made solutions and sophisticated automation.
Integrated future proof single answer responding to the various data centers challenges and business needs. The concept fully uses proven technologies, however it becomes interesting when you take into account the cost savings in the mechanical and electrical systems due to amongst others the smaller power need, construction materials (building volume can be cut by half). Flexibility in IT load rack from 1 to 35 kW per rack as a standard.
Overall the concept results in 25% cost saving compared to the most cost efficient TIER III data centers that we have developed till date. We believe that below 4,5 €/Watt of IT power is feasible for a TIER III Cube data center.
