Digital Realty Trust, Chandler (USA)

•    Total IT Load = 23 MW
•    White Space = 48,000 m2

Digital Realty provides co-location services worldwide. Deerns guided the whole commissioning process for their Chandler data centre. Furthermore we provided oversight of the process, the sequence of operation and the set points of the controls and building management system.

Istanbul Stock Exchange (TR)

• White Space = 600 m²
• Total IT Load = 1 MW
  

Deerns designs the new primary data centre of IMBK. The white space will be located in the former vault of the stock exchange. Deerns is responsible for the definition of the business requirements, conceptual and detailed design, tender documents, complete site supervision during construction and testing and commissioning. The whole process, from the start of the design until completion of the construction, will take about 6.5 months.

Innovation:
Guiding the Cloud

Many large cloud service providers have a network of data centres (e.g. Google and Amazon). Deerns developed a solution which provides an optimal performance of these networks: ‘Guiding the Cloud’. This data centre energy management method integrates the data centre facility and the cloud platform. It consists of a set of customized operational, review and energy management procedures, and is supported by software architecture. Deerns filed patent for this innovative method in the summer of 2011. 

Sberbank Mega Data Centre, Moscow (RU)

• White Space = 5,000 m²
• Power Density = 2 kW/m²
• Total IT Load = 10 MW
• Annual Average PUE = 1.3
• Peak PUE = 2
• TIER III

Sberbank is one of the largest financial institutions of Russia. Their data centre is constructed within an existing campus facility. It consists of three floors with white space, a floor with electrical installations and a floor with support facilities. Very strict requirements are met regarding reliability and sustainability. The construction is done in phases, such that operation of phase I and construction of phase II take place simultaneously.

Innovation: Cloud Control

Cloud data centres are characterized by fast fluctuations in the heat load generated by the IT equipment. To ensure that the cooling system is capable of coping with such fast variations, Deerns developed and patented the Cloud Control solution. This solution will deliver cold air to the cold aisle at the required temperature and pressure, regardless of the temperature difference over the racks. It allows our clients to be very flexible in the layout of their white space, while the performance specifications are maintained.

Rabobank Data Centre, Boxtel (NL)

• White Space = 6,500 m²
• Power Density = 2.5 kW/m² 
• Annual Average PUE = 1.26

Rabobank is an international financial service provider. State of the art sustainable energy consumption measures have been taken for this data centre, for instance: a highly efficient cooling concept, a ‘lights out’ principle, and residue heat from the data centre is used for heating and cooling of the office.

Gartner: "Best in class with no significant opportunities to improve on reliability or sustainability."

Global Switch, Amsterdam (NL)

Global Switch is an international co-location provider. For their data centre in Amsterdam, Deerns has been involved in many projects, for example the upgrade of white spaces during life operation (850 m²); a discrimination study of the electrical infrastructure to increase the reliability of the whole data centre; and the support of Global Switch with their long term strategy development of the site.

Innovation:
Chameleon Data Centre

Next to energy efficiency, extreme flexibility is a challenge in data centre development. Frequent changes demand data centres to be able to ‘change on the spot’. To meet this demand, Deerns has developed and patented the Chameleon© data centre, that changes on the spot to meet the needs of our clients. Combined with the GC-DC technology , the Chameleon DC leads to some of the world’s best PUE’s. Combined with the GC-DC technology , the Chameleon DC leads to some of the world’s best PUE’s. 

Read more about the Chameleon DC in our whitepaper ‘The Chameleon Data Centre: "Transforming to meet your business needs...".  This paper was part of the Uptime Institute Symposium 2010.

Equinix Data Centre, Amsterdam (NL)

• White Space = 2,800 m²
• Power Density = 2 kW/m²
• Total IT Load = 5 MW 
• Annual Average PUE = 1.4

The prognosis of the energy consumption of the data centre indicated that the power consumed by the mechanical installations would severely limit the amount of power available for the IT. Deerns conducted an energy assessment in order to improve the energy efficiency. During a life upgrade the improvements designed by Deerns were implemented. This resulted in an efficiency increase of the data centre by 22%.

T-Systems International, Magdenburg (DE)

• White Space = 10,800 m²
• Power Density = 2 kW/m²
• Annual Average PUE = 1.28
• TIER III

T-Systems is one of Germany’s largest telecom providers. To enhance the sustainability of their greenfield data centre, Deerns developed and optimized a cooling system for maximum benefit of the free cooling opportunity in the local climate. Moreover, the 'waste' heat of the data centre is used for the heating of the secondary buildings on site. 

Innovation: Green Cooling (GCDC)

Green Cooling for Data Centres (GC-DC) allows data centres to operate without chillers in a large part of the world. This GC-DC concept cools the data centre with outside air without mixing the outside air and the white space air. During 95% of the time 100% free cooling can be used, which reduces energy consumption by 80%, achieving an annual average PUE of 1.15 and a peak PUE as low as 1.40. This concept can be build up fully modular, allowing our clients to invest as they grow.

Read more about the GC-DC technology in our whitepaper ‘Three Steps To Perfectly Green’. This paper was part of the Uptime Institute Symposium ‘Lean, Clean & Green’ in 2009.

Internap, Secaucus (USA)

•    White Space = 10,000 m2
•    TIER III

Internap provides scalable co-location, hosting, and cloud services. Deerns designed their co-location data centre in Secaucus. The data centre is accommodated in an existing warehouse. Deerns was assigned as the lead engineer for this design & build project. Our team developed a concept with key features as ultimate flexibility, modularity, energy efficiency and availability to grow in the future. At the same time the concept offered the lowest total cost of ownership.

MegaFon Cloud Data Centre (RU)

Their first data centre:

• White Space = 5,560 m²
• Total IT Load = 18 MW
  

MegaFon is one of the largest mobile phone and telecom operators in Russia. They have the ambition to develop an infrastructure of Cloud Data Centres. The main idea for this infrastructure is that one module will be developed, containing the white space and necessary technical installations. For each data centre the desired number of units is determined and if necessary changes can be made to make a data centre qualified for its environment.

KPN Data Centre, Haarlem (NL)

• White Space = 1,800 m²
• Total IT Load = 4 MW 
• Annual Average PUE = 1.2
  

KPN is a leading international telecom provider. For their data centre in Haarlem, Deerns upgraded the cooling system, which improved the energy efficiency. During this life upgrade the KyotoCooling technology was integrated with the existing and live data centre, without any interruption of the IT processes. The combination of competitive pricing, low risk and high energy efficiency of the upgrade resulted in substantial business benefits for KPN.

Cybercentre, KPN, Amsterdam (NL)

KPN Vastgoed gave Deerns the challenging task of transforming an existing office building (approximately 25 years old) into an ultra-modern CyberCentre that will be one of the largest Internet distribution centres in Europe. The KPN Telecom CyberCentre is a top-end platform equipped with an advanced technical infrastructure for all conceivable Internet applications.

Innovation: Cold Water Storage

To increase energy efficiency of a data centre, Deerns applies ATES (Aquifer Thermal Energy Storage) technology as an add-on to the standard CRAC-Chiller-Cooling Tower solution. During winter time very energy efficient and low cost cool water can be produced. This is stored in the natural aquifer storage. In summer time this cool water is used to increase energy efficiency and to achieve peak shaving of the total facility power required. In areas where aquifers do not exists or are not feasible, it is possible to construct artificial surface storage.
