Data Center Infrastructure

Performance, Reliability and Security
6 data centers around the world, including 2 of the largest ones. Since its first data center in Paris back in 2003, OVH keeps on innovating when it comes to designing, deploying and maintaining its server hosting infrastructures.


A global end-to-end management concept was implemented for its data centers, and it now has a unique know-how in terms of high availability, security and energy efficiency.
Over 12 Tbps capacity

Your website is hosted in our Tier-3 Data centers. A high availability network infrastructure, utilizing multiple premium bandwidth providers and with multiple Points of Presence (PoP) in the United States. This Trans-Atlantic backbone guarantees your web hosting products’ low latency and bandwidth quality, wherever you are!

Quality Network

To ensure high speed, low latency superior quality bandwidth, our data center has invested in the deployment of its own fiber optics network. Managed with DWDM equipment. Our network is world-wide in scope. Our routing infrastructure is fully based on Cisco products, due to a privileged partnership.


To guarantee the maximum redundancy and availability of your hosting product, all network links are at least doubled at every routing point. Two Cisco routers (each with two network cards) make up the physical connection to your dedicated server. The fiber optic cables are at least doubled, and sometimes tripled.

Anti-DDoS protection

OVH includes a protection against all types of DDoS attacks in its dedicated hosting service. The web hosting provider has set up 9 anti-DDoS infrastructures with a capacity of 6x600Gps + 1x 240Gbps + 2x120Gbps across the group’s data centers.

In-house developed servers

OVH produces its own servers in-house and has multiple production lines in France and Canada. As a result, the latest generation components are built into the machines, increasing reliability and adaptability.


Our data centers are protected 24/7 by a security control system, video surveillance and on-site security staff. The rooms are also equipped with state of the art fire detection and extinction systems. Our technical teams are on site 24/7, ready to intervene.


  • ISO 27001:2005 certification for providing and operating dedicated cloud computing infrastructures
  • ISO 27002 and ISO 27005 certification for security management and risk assessment norms and associated processes
  • ISO/IEC 27001:2013 certification for the security management of dedicated server information system.
  • ISMS certification for dedicated servers covers all servers hosted in certified datacenters in France, as well as all in Canada, Singapore and Australia
  • SOC 1 Type II and SOC 2 Type II certifications
  • N4 and APSAD R4 for fire risk management
Data protection has always been one of our top priorities. In order to guarantee the very highest security levels, we have carefully put efficient measures in place, as well as an arsenal of good practices at all levels of our organisation and infrastructures.

High security Datacenters

In all datacenters, access is strictly monitored. To avoid any intrusions or risks, each perimeter is secured with barbed wire fences. The area is also monitored by constant video surveillance and motion detection sensors. Activity both within and outside of the datacentres is monitored and recorded on secure servers, with surveillance teams working on site, 24/7.

In order to control and monitor access to the premises, strict security procedures have been put in place. Each staff member receives a RFID name badge, which is also used to restrict their access. Employee access rights are reassessed regularly, according to their remit. To access the premises, employees must hand in their badges for verification before passing through the security doors.

The datacenters have an even higher level of protection, as only authorized personnel can gain entry. No colocation is allowed, thus all datacenters are strictly for internal use.

Fire risk management

Every datacenter room is fitted with a fire detection and extinction system, as well as fire doors. All datacenters comply with APSAD R4 regulations for the installation of mobile and portable extinguishers, and have N4 conformity certifications.

Industrialization of liquid cooling

One of the key elements in terms of energy efficiency is industrial deployment of water cooling systems.

This idea was born in 2003 and had never been used before on an industrial scale. All dedicated servers are cooled individually using liquid cooling. The liquid is carried by heat exchangers which are positioned on the processors and as well as other components that emit the most heat.

70% of the heated generated by a server is thus captured by the liquid, which has a much higher heat transfer capacity than air.

Network Security

OVH deploys its own global fiber optic network. Hardware at the cutting edge of technology is selected, installed and maintained by in-house teams of engineers.

With this network, we can deliver fantastic service quality to all of our customers, no matter where they are based. The network has a capacity of 8 Tbps in Europe, and 4 Tbps in North America. It is also connected to 33 points of presence across four continents.

We have designed the network to be fully redundant: several security loops have been put in place to eliminate any risk of services becoming unavailable. With this abundance of links, your data can take the shortest route, resulting in minimal latency and the fastest load times.

Server Security

There is a 24 hours a day and 365 days a year human presence in the datacenters, to guarantee that the servers are constantly maintained. In the event of a technical incident, they will react immediately to ensure that your server is repaired as quickly as possible.

Some of the server ranges are also equipped with double power supplies and double network cards, so that the infrastructure is redundant from end to end.

Electrical Supply

The datacenters are powered by two separate electrical power supplies and are also equipped with UPS devices. Power generators have an initial autonomy of 48hrs to counteract any failure of the electricity supply network.

Eco-innovation is at the heart of our selected datacenters philosophy. Since 2003, we have been working to reduce the energy consumption of these data centers, particularly by designing an exclusive liquid cooling system for our servers.


No stone is left unturned to invent new ways of reducing the quantity of electricity needed to run its datacenters. This keeps the ecological footprint down.

Since 2010, the data centers that we have selected have been cooled without the use of air conditioning.

The “30% aircooling + 70% water-cooling = 0% air conditioning” solution is deployed in all our new data centers. It has significantly reduced our energy bill, so much so that electricity now only accounts for 10% of the overall operating cost of our data centers.

Optimization of air flow

Rather than the traditional free cooling commonly used in data centers, the servers are cooled directly using air from the outside.

The way that the data center has actually been designed plays a key role in this highly effective air flow management system. The tower design allows fresh air to directly reach the front of the servers, which regulates the temperature of the fans and air inlets.

  • Fresh air passing in front of the servers
  • Air heated by the components is evacuated at the back of the servers
  • Hot and cold air flow separated

Industrialization of liquid cooling

One of the key elements of the OVH strategy in terms of energy efficiency is industrial deployment of water cooling systems.

This idea, born in 2003 and going against the current practices of the time, consists of using liquid inside the server itself to cool the processors. The liquid is carried by heat exchangers which are positioned on the processors and other components that emit a lot of heat.

70% of the heated generated by a server is thus captured by the liquid, which has a much higher heat transfer capacity than air.

Record PUE index

The PUE is the energy efficiency indicator for data centers. Thanks to its efforts to reduce its electricity consumption, OVH has achieved an average PUE of 1.09.

A better result than the average data center.
