Green datacenter 'Marilyn '.
Data centers consume a lot of energy. In addition to the computer servers, whose consumption can be optimized, the release of heat from the servers is very important. Current data centers consume energy to produce cold in order to limit the temperature of the rooms.
The P.U.E ratio. (Power Usage Effectiveness) is used to determine the performance of data centers. The P.U.E is defined as : overall site consumption / consumption of computer equipment 1 year of operation. Many actions are undertaken by players in the market to reduce the P.U.E. In the project 'Marilyn '., an innovative and effective approach is proposed to provide answers.
Marilyn is the 1st ecological datacenter high density in France and an emblematic site of the Cité Descartes, Sustainable development of Grand Paris pole.
Power consumption optimized
The average of the existing sites in France the PUE of 2,5, According to recent studies. New projects today target ratios of 1,8 or even 1,6. A recent study in the US showed this ratio disparities between 1,34 and 3, for data centers in operation.
Power consumption target data center 'Marilyn' is a P.U.E. target (performance) from 1,3. Thus the ambition of the Marilyn concept is to have a very high energy yield.
Technological options to reduce the power consumption of the site are multiple :
- Architectural innovative design to cool a high density datacenter in "all air"., without production of water ice
- Use of ambient air ("free-cooling".) 80% of the year
- Recycling of heat from the machines to heat offices
- Billing of power consumption on each power supply for each client
Ecological choices at all levels
To reduce the overall energy footprint in the data center, other solutions have been implemented
- Refusal of batteries (lead) flywheels inverters for
- Refusal of copper for wiring in Fibre Optics on 100% Sitemap
- Implementation of the recycling of the materials
