CyrusOne Data Centers

DFW3, DFW4 and DFW5 form CyrusOne’s premier data center campus in Allen, Texas, just north of Dallas. Spanning over 90 acres, it’s the largest data center development in the state, purpose-built for high efficiency and resilience in large-scale IT operations.

The campus delivers up to 50 megawatts of critical IT capacity across three state-of-the-art facilities totaling 976,000 square feet. Each building is optimized with water-free cooling systems, low PUEs, and a closed-loop air-cooled chilled water design supporting up to 180 watts per square foot.

Security is multilayered, featuring biometric dual-factor authentication, anti-tailgating vehicle systems, perimeter steel fencing, and 24/7 surveillance. Sustainability is baked into the site’s DNA, with renewable energy sourcing and a Green Globe rating of 3 Globes.
