Iliad operates several data centers in the Paris region, all designed in-house by its own engineers, for corporate and Internet-industry customers. DC2 in Vitry with over 5,000 m² has been fully modernized and boasts a new 2 N+1 architecture. The DC3 campus will be inaugurated this summer, implementing an innovative Tier IV architecture, comprising 22 private 250 m² data centers over a total area of 11,800 m².

Iliad Datacenter issued a tender to the majority of equipment manufacturers. "Ultimately we selected the Eaton 9395 solution for its rich feature-set, its redundancy and its European manufacturing (Finland). We commissioned 29 Eaton 9395 550 kVA UPS, each composed of two 275 kVA modules. We use these UPS to safeguard the integrity of our customers’ infrastructure." explains Nicolas Fontés, Sales Manager, Iliad Datacenter.

"In a data center, 70% of our operating costs are electricity costs with rates that are increasing by an average of 7% per year," notes Nicolas Fontés. "We wanted to maximize efficiency up to 97.9% on the chains. The adoption of the ESS mode (Energy Saver System) of the Eaton 9395 on all our chains, is a first in France."

For outstanding efficiency, the Eaton 9395 UPS implements another new technology with an enabling modular structure, called VMMS (Variable Module Management System). Instantly reacting to the load level VMMS automatically senses the number of uninterrupted power modules (UPMs) to activate and those to put on ready state. Active modules are always used at a high load threshold. When the load increases the system immediately activates - in less than 2ms - additional modules.

To achieve 98% efficiency without compromising on quality, Iliad Datacenter has installed sensors providing information and alarms. To maintain a high level of redundancy and maximum quality, everything must be flexible in the DC. The innovative modularity of the Eaton 9395 delivers this flexibility.
"In the DC2 data center, these UPS are already in operation. In our tests before deployment we pushed the material beyond its operational limits. And we were delighted because the results were well above our expectations!" comments Nicolas Fontés.

Eaton Hot Sync technology for paralleling UPS

Iliad Datacenter has adopted Eaton Hot Sync UPS paralleling technology. Hot Sync ensures not only very accurate load sharing but also enables real-time detection of a faulty UPS. In fact the operation of each module is self-monitored. If it detects a potential problem it instantly disconnects and the additional load is offset by other UPS. Eaton filed the patent for this 15 years ago. This technology, available on Eaton UPS configurations from 8 kVA to 1.1 MVA per unit, can scale up to 6 MVA with centralised bypass.

A trouble-free deployment

"The Eaton Projects team, composed of technical experts, fitted in well with the schedule we had set. They organized delivery stages, deployment and commissioning of equipment within the set time-limit. In addition they carried out, at the site in Vitry, a system analysis to determine the functional scope of the system." remarks Nicolas Fontés, "We went from a traditional solution with 92% efficiency up to 98% efficiency. Bearing in mind we have a load of 22 MVA, this is really considerable!"

Eaton systems: combining efficiency and quality

"As I have already mentioned, Eaton offered us a product that surpassed our targets for efficiency and redundancy. In addition our engineers were able to carry out many on-site tests, particularly short-circuit and overload tests, and the results were even better than we had hoped for. It is true that Eaton has a heritage as an equipment manufacturer for vehicle and aerospace industries, where the provisions for safety and traceability are pushed to the limit. Eaton was also able to adapt, at our request, certain technical elements of its UPS to improve the solution. Technical teams from Eaton have the same DNA that we have for innovation!” concludes Nicolas Fontés.
