The quality of a datacenter is related to its power consumption optimization

Even if operators defend, the increase in electricity tariffs handed 'flat' traditional operation of data centers.

Originally for reasons of deadlines for placing on the market and economy of investment, the concept of the datacenter was modelled on that of the computer rooms. Investments were focused on technical equipment : air conditioners, electrical transformers, UPS... and their back-ups. For buildings, the model was the rehabilitation of space "offices"..

This approach has for some years exceeded its limits, and this for several reasons :

Too low electrical performance of these facilities

Recall here the requirements of a datacenter in electric power. To deliver power from 1kVA to hosted servers, It took additional 1kVA for air conditioning and double for each of their security system. Therefore a Bay of 10 kVA implied availability of 40 kVA.

The cost of this electric energy

Initially this cost was insignificant, but now a few years we are seeing an increase in annual and continuous between 5 and 7 % of this energy in the world : that is, in 4 years price per Kilowatt «took» more 25 % increase, and everything suggests that this escalation will continue (Source Reuters).

Quality of service guarantee in time

By definition, hosting servers is an approach that fits in the duration. For a Datacenter operator it means it must calculate its operating budget for several years, While most large amount was entirely outside its control : the cost of Kilowatt.
In this context, to maintain in operational condition their offerings, datacenter operators have only two solutions: either they regularly increase their rates to absorb this inflation, either they "are cutting back" on other expenses by agreeing to degrade the quality of their hosting services. The first approach is generally contractually impossible, It is only the second. It is ironic that it was precisely to prevent this degradation of the quality of the environment of its servers that the client has chosen to outsource its servers in a professional data center.
Let us not defeatist, because not only solutions exist and they are already marketed. Their implementations to generate substantial energy savings for a same accommodation capacity thanks to :

  1. The redesign of the cooling processes of data centers with the use of less expensive resources, natural resources as ambient air with free-cooling
  2. The use of inverters to inertia instead of batteries (less consumer of electric power for their maintenance in operational condition)
  3. An optimization of the use of certain equipment by the pooling of their function for the data center

In summary, We can consider that for a client the guarantee of the quality of a data center is its ability to optimize the use of electric power for computer servers hosting.

Capsule technology chooses Marilyn for the hosting of its data

To meet the high-availability and storage of its data security issues, Capsule technology has made the choice to outsource its production within the HEAVENLY Datacenter infrastructure, Marilyn.

Global leader in connectivity solutions of biomedical devices in the hospital information system, the Capsule technology group responds to a growing problem of hospitals : documentation of the computerized Patient record and the specialty folders. Connectivity options apply to all the services of the hospital, whether it's critical care environments (intensive care, operating room…), General care (surgical services, medical services…) or emergency.

The key elements of the solution Capsule, the connectivity DataCaptor ™ software and the Capsule Neuron ™ platform, make a patient-oriented solution that integrates seamlessly with the technologies and infrastructures in place while greatly improving the methods of work of caregivers.

In order to meet growing storage-related problems to the exponential growth of the group abroad, and particularly in France and in the United States (80% supplementary CA annually, and multiplication of numbers by 2 in two years), Capsule has decided to outsource its production within the HEAVENLY Datacenter infrastructure, in Champs sur Marne. Indeed, the maintenance of the infrastructure became too binding, expensive and subject to repetitive failures.

Beyond the geographical proximity between Capsule France and CELESTE, the Marilyn site was prior to any selected on criteria of sustainable development and innovation. Indeed, TIER IV design with a fully lined electric chain, Marilyn offers a level of availability of 100%. In addition, the site's security is enhanced by many technical and human resources : biometric access, surveillance cameras, control intrusion or guardians, without mentioning the site management procedures.

In order to strengthen the high availability of the infrastructure, two computer centres CELESTE and Capsule are connected by a Lan To Lan (interconnection) secure two links fibre-optic-based 1 GIGA. In addition, two data centers are connected in double piped through two different paths.

Taking into account the close cooperation between the two companies, of many developments and services are planned to migrate this project to issues products Capsule.

«The choice of CELESTE is a strategic choice for Capsule» says Marc DIZIEN, Director of the Office of the Global information systems in Capsule, 'in addition to the problems of storage., maintainability and evolution of existing infrastructure of Capsule, We will respond to those of our customers : hospitals. Indeed, the sensitivity of the treatment and securing patient data is such that referral to specialists in the secure hosting is essential. » He concludes.

About Capsule

Capsule is the world leader in biomedical connectivity solutions. Hardware and software products innovative capsule allow to automate and improve the nursing process by linking biomedical devices to the Information System of hospital.

Care facilities using medical records computerized and other solutions software business can easily and quickly set up supply Capsule. It is independent of suppliers of biomedical devices, modular and expandable to desire and reduces costs, to increase productivity and improve the quality of care.

The solution of Capsule presents another major advantage : It fits perfectly to the technologies and methods of work already in place in the hospital. Founded in 1997, over the years, the company established numerous partnerships with leading manufacturers of medical devices and information systems providers. The Capsule solution is installed in most of 1100 hospitals across more of 35 country.

Towards a new type of green datacenter

Launch of a new generation data center : Marilyn

CELESTE ENIA Architects and sign a joint patent for a new generation data center consumes less energy. The first prototype operated by CELESTE will emerge in Marne-La-Vallée in June 2011.

ISP for businesses, CELESTE has partnered with ENIA Architects to develop its new concept of data center. The combination of the two players has led to a patent and the project of a data center in Champs-sur-Marne, at the center of future cluster Eastern Ile-de-France.

CELESTE and its agency knew created the event with this project, innovative both technically and architecturally. Indeed, the market for data centers proves unsuited to age and ecological constraints in terms of power consumption of air conditioning for cooling computer rooms. In addition, the explosion of accommodation and offers virtualized applications implies a lack of availability including Ile-de-France.

The main innovation of this project is based on the vertical building construction. The data center will operate in total “free-cooling” with the use of outside air to cool server rooms. These built on five levels will benefit from a natural draught and an optimization of the aeraulic yields effect.

The gain in total power consumption is estimated at around 35 %, a saving of about 6 GWh per year compared to a traditional data-center. This saving represents the annual consumption of a classical building offices 150 000 m² and limits the release of CO2 into the atmosphere 540 tonnes.

In addition to energy savings, this vertical arrangement allows an optimized organization of data center needs and limitations of floor. This feature makes thus possible implantation in urban areas. The coup, the unit cost to the kVA of Bay installed in this type of installation is divided in half.

Designed to accommodate the headquarters and data center CELESTE, draft is based on a total surface of 1800 m2. Located on street, within the Cité Descartes Champs-sur-Marne, office building will continue in two computer towers positioned at the rear of the plot in a coherent Figure.
