After months of confidential development, BSO has announced the creation of DataOne, Europe’s first giga-scale AI hosting infrastructure data centre.
Located in France and financed with the support of the Ardian debt fund and leading commercial banks, this ambitious project stems from the acquisition of an existing Tier 3 data centre campus.
Currently, the data centre offers 15MW of IT load, spanning 50,000 m² across 14 hectares in Grenoble (Eybens) and Lyon (Villefontaine).
These ISO 27001, 14001, 50001 and SOC 1 & 2 certified facilities are trusted by leading global companies.
DataOne’s carrier-neutral campus and AI-agnostic customer infrastructures are interconnected via dedicated dark fibre and 100G+ DWDM wavelengths. This is made possible by a robust ecosystem of seven connectivity providers, with plans to onboard more.
By 2028, DataOne will deliver 400MW of AI-compatible infrastructure, becoming the largest data centre in Europe. The facility will integrate renewable energy sourced from EDF’s hydroelectric power, complemented by nuclear energy backup, ensuring zero-carbon operations at scale.
Deployment timeline
- April 2025: Launch of 80MW capacity, following 16 weeks of transformation work, establishing Europe’s largest AI-focused data centre. The facility will be capable of hosting customer supercomputers and competing with global benchmarks
- Q4 2026: Expansion to 200MW capacity
- Late 2028: Completion with 400MW operational capacity
Tailored to the demands of current and next-generation GPU technologies, DataOne will feature direct liquid-cooled Facilities Distribution Units (FDUs) capable of hosting heterogeneous AI infrastructures with power densities ranging from 60 to 250KW per rack. The data centre’s design achieves a Power Usage Effectiveness (PUE) of 1.06–1.15, significantly surpassing European regulatory standards.
