Logo Econocom

Independent European leader for computer and telecoms infrastructure management, Econocom Group offers innovative services solutions, particularly in the area of the Cloud. The company has opted to outsource a part of its infrastructure within the HEAVENLY Datacenter boasting a very high availability and security. A Datacenter CAMPUS was able to see thanks to the partnership with CELESTE, campus including extensions at a European level are planned in the coming months. The objective of this CAMPUS is to provide Cloud services to the unified time and closer to customers.

To implement this strategy winning and based on innovation, the Group relies on its European expertise centre, recognised contributors, a robust network infrastructure and values of responsibility and entrepreneurship. It is therefore no coincidence if the HEAVENLY Datacenter has been retained in the context of the evolution of the company’s infrastructure.

Beyond the geographical proximity between the datacenters Econocom and CELESTE, the Marilyn site was prior to any selected on criteria of sustainable development and innovation. However, the EEP target of 1,3 Marilyn is not the sole criterion of choice for this ‘Datacenter campus project « .. 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 ECONOCOM 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 being considered to develop this unique project of CAMPUS accommodation, which meets the expectations of companies in terms of reliability and performance.

Eric GUILLOT, Director Global Services Centres, “the choice of CELESTE is a strategic choice for Econocom which allows us to propose solutions for the future for our customers; We have very important ambitions of development around this partnership and already our new offerings meet a great commercial success”
Created there 37 years, Econocom is the first independent European Group of telecoms and computer infrastructure management. Fort of complementary expertise (distribution, funding, services and telecoms) and its range of innovative corporate solutions, Econocom assists companies in the transformation of their information systems.
Implanted in 17 country, Econocom group account 3 700 employees for a turnover of 1 584 million euros and a current operating result 66,6 million euros in 2011.

Obsolescence of data centers and servers, a matter of availability

The interest of a company to put its servers in data centers based primarily on economic reasons : eliminating the costs of air conditioners, UPS, security access, maintenance of the room etc …. However it is necessary to remain vigilant on the quality level of service to which it entrusts its servers. Is it useful to remember that for most companies the « blocking » of its information system means a complete cessation of its activity ?
A recent study showed that 60% Failures of computer servers are due to failures from the environment wherein they are installed :
– Breaking of the electrical network, automatic or without sufficient recovery by UPS,

– Failure of air conditioners, transforming the computer room in a « sauna »,
– Dust deposition, generating false contacts in the circuits of servers

Originally many datacenter were built from the refurbishment of office buildings under the pretext that they already had a computer room. This leads to a rehabilitation facility originally healthy, but quickly reached their limits of reliability as and when they are « filling ».
Beyond an occupancy rate 70 %, it is common to see appear amenities that erode the reliability of a data center, for example :
– Creation of private rooms but only one air conditioner or without backup UPS lack of space
– Reducing the number of test operations and maintenance due to access difficulties : air conditioners in the rooms berries, rooftop
– Poor distribution of cooling air flow after changes in the arrangement of rooms : deletion or addition of partitions
– New equipment rooms without duplication of electric meters due to wiring problems or siteThese disparate changes have not only led to a decline in the quality of data centers, but also more complex daily operations : multiple interventions, difficulty of access, absence of substitution solution during interventions. Besides, it is common for operators to give up announcing the closure of their old datacenters.So what should be done ? Resume its servers. Not at all. You just keep in mind that outsourcing server is a project that falls within the period. It is entrusted by its servers for 12 month. One should choose a provider capable of providing consistent operating environment for 10 years to come whatever its filling rate, changing technology computer servers, operating costs … a datacenter XXI century.

The Marilyn Datacenter keeps its promises

One year after the commissioning of the datacenter ‘Marilyn’ of the ISP to Internet CELESTE, It is an opportunity to revisit the first results of its operations. We interviewed Nicolas Aubé, President of Marilyn

M. Aubé, can you remind us why this datacenter is innovative ?

NA : This is the first ecological computer center and high density. Its vertical design allows a cooling by ambient air almost year-round. The hot air generated by the server is used for heating our offices, the surplus is discharged via automatic shutters at the top of the towers.

Why this name of Marilyn ?

NA : Because we thought the famous actress in the movie ‘Seven year itch’ when her dress flew on an air grille. In our datacenter, the air passes through the floors and can soar dresses !

Your project aroused the interest of the public ?

NA : Yes, We were the first surprised. We did a first session open door which has been so successful that we have fact… 20 editions. We have had many reports of press paper/Internet and national television channels. I believe that the hidden face of the Internet interested public.

Is the operation optimal year-round ?

NA : Since commissioning in October 2011, in marne-la – Vallée, We had the opportunity to test extreme outdoor temperatures between-15 ° C in February and 40 ° C in August. Ambient humidity ranged from 15% to 100%. We were able to validate all of the beaches of functioning of the datacenter.

What are the modes of operation ?

NA : Cold mode is when the temperature is less than 22 ° C, either 80% of the year. There not need air conditioning to cool the air. We recycle hot air discharged by computers and mix it with cold air, outside, in order to blow air to a temperature between 17 ° C and 22 ° C in the cold columns before the servers. The cooling mode is so effective that we had to limit it the first weeks, front rooms are filled, because the temperature tended to be too low.
A very good surprise is also functioning in the ranges between 20 -22 ° C : cooling by ambient worked well even in these relatively warm temperatures : the temperature in the rooms was not higher than the outdoor temperature, Despite hundreds of computer servers in operation. And this without any air conditioning. This is the heart of our model : We only spend the energy to turn computers, not for air conditioning.«Warm» mode is between 22 ° C and 32 ° c.. Here, We always use the outside air, because its temperature remains lower than expelled by servers. We climatisons the outside air to bring it back to 22 ° C, and we repel any warm air by the roof. This mode remains effective enough.
The ‘hot’ mode occurs above 32 ° c.. We then operate closed circuit, cooling the hot air produced by the servers, as a regular data center. In this mode, We don’t realize economy, but it represents only 5% of the year. We have noticed also that it remains interesting to partially open the flaps at the top of the towers, to create a depression in the hot aisle and a natural drawing effect.

What are the constraints of the process ?

NA : It requires a tight seal between the front of the servers (cold aisles) and the rear (hot aisles). For this, We provide our clients with caches. We found that in the case of too much fresh air leaks, We increase the pressure in the cold aisles.

How have your customers they accepted these innovations ?

NA : We were a little worried on knowing if our customers accept this model of vertical computer room ; and even if some would not have Vertigo because it works above 5 floor gratings. However we are pleased to see that this is not the case, customers immediately joined our concept and these innovations have been rather a commercial engine as a brake.

Why do you say that the Marilyn datacenter is in high density ?

NA : It’s available for Bay power. Through our process of cooling, We provide berries in high density without any modification at our facilities. The datacenter is equipped with a medium density 5 kVA per Bay, What is significantly higher than the other datacenters we know in France. We provide standard arrays up to 10 kVA.

Customers need this high density ?

NA : It depends on the type of equipment and use. We find that customers who use servers blades, making virtualization or cloud computing need high-density. However they need less space. One of our customers had a suite of suite 10 berries with 20 kVA in a datacenter in island of France. He chose to move in CELESTE taking that 2 high density arrays, with 20 power kVA. He was able to achieve savings in the management of its facilities and its data center budget.

As with other data centers including one in Courbevoie, have you suffered outages this year ?

NA : Non, the datacenter has been available to 100% as we guaranteed it to our customers. Indeed, We have two completely independent electric strings, in separate buildings, Since the high voltage to the distribution in the bays.

Can you tell a client reference of the Marilyn datacenter ?

NA : For example Econocom, a leading European integrator. They have been seduced by our innovations in terms of reduction in energy expenditure. They have trusted us since the opening of the datacenter.

Have what changes you made since a year ?

NA : We have extended the commercial range in terms of density. Indeed, We were able to respond to calls for tender seeking up to 15 kVA per Bay. In addition we also put in the catalogue of the berries with 1 kVA for low consumption requirements. We launched berries « cloud » with variable consumption, charged to the use. This offer is ideal for Cloud computing providers. We have also exploited the synergies with our range of fiber 1 Giga. We propose an offer coupled with a Bay in our datacenter Marilyn and a fiber optic to 1 Giga Ethernet VPN client.

Concretely what benefit this offer brings to the Manager of an undertaking located in Paris for example ?

NA : He moves his computer in a green datacenter. It has access to its remote servers as if they were on its local network of Paris. He won the m2’s Parisian premises, decreases its electrical costs and enhances the security of its systems. If it is the choice of Marilyn as a back-up site it has a high availability and redundant infrastructure.

What are your plans for the future ?

NA : En 2013, We planned to equip the second tower of the Marilyn datacenter. Furthermore, CELESTE is a member of cloud, the collaborative research project on cloud computing, which is supported by the State ecological. In this respect, We are working on a model of data centers network, dedicated for the cloud. We have also been approached by investors or manufacturers who wish to reuse our patent ‘Marilyn’ in France or abroad. We have designed a license therefor agreement.

In which countries the datacenter Marilyn could be replicated ?

NA : in many countries ; If the climate is not too hot and dry. Everywhere in Europe, except South ; in the North, the centre or East of the USA, in the Brazil, in Southeast Asia, at the Japan, in South Australia.
Nicholas Aubé, Thank you

Marilyn datacenter, a 100% availability warranty

Just after 10 months of work, construction datacenter Marilyn CELESTE ends for commissioning in late September. Technological choices made throughout the project are now Marilyn the most innovative datacenter : ecological, high density with availability 100% and the power supply for maintaining the temperature.

Last October, the first stone of the computer center is placed CELESTE ; and 10 months after the datacenter is already almost finished. This new concept of datacenter arouses curiosity, panel visible presentation of the A4 has much. Visits are increasing daily : Hosts, banks, SSII or curious of all data centers Ile de France…

I must say that the technical choices make CELESTE Marilyn the most innovative datacenter year

  • Double electric chain with arrival ERDF 3MW
  • Two HV 20 000 In
  • 2 BT with local
    • tables with service levels “3 3 3″ to perform Maintenance, room change or upgrade hot
    • two inverters with inertial component thus avoid cool battery
  • Electrical distribution doubled for each bay
  • A generator sized to resume full power center

In conclusion, this architecture design TIER IV ensures availability of 100% power supply and temperature maintenance with a simple and robust approach. This is what attracted visitors beyond the quality of the suppliers selected for berries, inverters or energy efficiency very low 1,3 (PUE).

Originally patent Marilyn and President of CELESTE, Nicolas Aubé is surprised and delighted by the enthusiasm of the community to Marilyn “Requests for visits and solicitations conferences worldwide are increasing and the rate of pre-booking is higher than expected. We are proud and excited at the same time be 26 September for the first breaths of Marilyn.”
