AMS-01 (Haarlem, Netherlands)
The AMS-01 data center offers exceptional scalability for LeaseWeb clients, with the ability to grow from its current footprint to as much as 40,000 square meters (431,000 square feet). Its architecture was built with expansion in mind, featuring independent A+B power feeds, redundant generator systems, and UPS battery backup units to ensure uninterrupted power delivery. The existing 20 MW power capacity can be increased to 40–80 MW as customer demands rise.
To protect customer equipment, the facility is equipped with a VESDA early-warning fire detection and suppression system, complemented by fire-resistant construction throughout the building to maintain structural safety and safeguard critical infrastructure.
AMS-01 is also recognized for its strong environmental performance. The site operates on a fully CO₂-neutral basis through extensive energy-efficiency measures, reliance on renewable power sources, and participation in global sustainability initiatives in partnership with the Climate Neutral Group. These efforts are aimed at restoring atmospheric CO₂ balance and supporting long-term ecological preservation.
Additional energy reductions are achieved through advanced cooling approaches such as Cold Aisle Containment, which optimizes airflow by enclosing the cold zone to prevent air mixing, significantly reducing the cooling load. The center also employs Free Cooling technology, drawing in filtered outside air when temperatures allow, thereby reducing reliance on mechanical chillers and lowering operational energy use.
A study by the German Federal Ministry for the Environment in 2009 highlighted AMS-01 as one of the most energy-efficient data centers globally. In the Netherlands, the facility participates in the Multi-Year Energy Efficiency Agreement (MJA), a nationwide initiative among leading IT organizations targeting a 30% energy-efficiency improvement over 15 years.
As an early adopter within the Green Grid community, AMS-01 consistently pursues new methods to enhance efficiency. Its Power Usage Effectiveness (PUE) rating currently stands at 1.2—far below the global average for commercial data centers—and the facility continues to refine its infrastructure to reduce this figure even further.
myLoc (Dusseldorf, Germany)
At its Düsseldorf headquarters, myLoc managed IT AG operates a network of seven data centers offering more than 3,500 m² of technical floor space, designed to support a wide range of deployment scenarios. All facilities are powered by a fully independent infrastructure that ensures stable and reliable operation.
One of the distinguishing elements of the myLoc portfolio is the DUS1 data center, which is equipped with its own combined heat and power plant. This on-site energy system supplies both electricity and cooling, providing a high degree of autonomy and efficiency. Across all locations, uninterrupted operation is maintained through robust UPS systems and backup generators (NEA), ensuring resilience against power disruptions. Each individual myLoc data center delivers an annual power availability of at least 99.95%. When workloads are distributed across multiple myLoc facilities, effective uptime approaches nearly 100%.
Six of the data centers, along with the company’s main administrative site, are situated at Gatherhof 44, 40472 Düsseldorf.
Key infrastructure and security features include:
- 24/7 video monitoring
- Layered access control mechanisms
- Argon-based fire suppression systems
- Fire-resistant room-in-room construction (F120 and F90 rated)
- Redundant climate control systems
- Ring-shaped connection to the 10 kV power grid
- Power delivery of up to 10 kW per square meter
- Dual-capacity supply lines for enhanced reliability
OVH WAW1 (Warsaw, Poland)
OVHcloud operates a highly resilient global backbone that links all of its data centers into a single, cohesive network. This backbone is further integrated with the public Internet through a wide distribution of Points of Presence (PoPs) positioned around the world. The network has been engineered with strict priorities on redundancy, security, minimal latency, and precise traffic management.
Because the Internet is an aggregation of independently run networks, overall quality cannot be uniformly guaranteed. To address this, OVHcloud continues to expand and reinforce its own international infrastructure, ensuring consistently high performance and reliability for customers regardless of location.
Key global network capabilities:
- 70 Tbps total backbone capacity
- 38 data centers spanning four continents
- 44 redundant PoPs strategically deployed worldwide
