OVH Cloud: GRA3 Data Center

The GRA3 Data Center is part of OVHcloud’s flagship Gravelines campus in northern France, one of the largest data center campuses in Europe. Strategically located near Dunkirk and close to major connectivity routes between Paris, London, Brussels, and Amsterdam, GRA3 plays a central role in OVHcloud’s pan-European infrastructure platform.

Gravelines benefits from proximity to one of France’s largest nuclear power plants, enabling access to stable, high-capacity energy supply. GRA3 is purpose-built to support OVHcloud’s public cloud, private cloud, bare metal, and hosted infrastructure services, delivering scalable, high-density compute environments designed for enterprise, hyperscale, and digital-native organizations.

As part of OVHcloud’s vertically integrated model, GRA3 incorporates the company’s proprietary server designs, water-cooling technologies, and energy-efficiency innovations to optimize performance and sustainability.
