“High-power compute demands more than simply adding power density. At Ark, we design environments that can support the future of AI and HPC workloads without compromising efficiency, resilience or operational stability. By combining high-density capability with advanced cooling and long-term thinking, we enable our clients to scale confidently as compute requirements continue to evolve.”

Resilience

Designed to stay online. Ark infrastructure is engineered for continuous operation, with resilient power, cooling and backup systems built in as standard. Proven redundancy frameworks and rigorous operational processes ensure uptime, even under adverse conditions.

High-power compute workloads place exceptional demands on data centre infrastructure. As AI, machine learning and advanced analytics move from experimentation into production, organisations require environments that can support sustained high densities without compromising resilience, efficiency or long-term flexibility.

Ark designs and operates data centres specifically to meet these demands. Our campuses are built to support high-density compute at scale, with power, cooling and structural resilience engineered in from day one. This enables clients to deploy advanced workloads today while remaining confident their infrastructure will support future growth.

Unlike short-term, retrofitted solutions, Ark’s approach is grounded in long-term performance. Power availability, heat rejection, redundancy and maintainability are considered holistically, ensuring that high-density environments remain stable, predictable and efficient under continuous load.

State-of-the-art cooling systems are central to this approach. Ark deploys advanced cooling architectures designed to manage modern rack densities efficiently, supporting consistent thermal performance while minimising energy waste. This allows clients to push compute performance without introducing unnecessary operational risk or inefficiency.

Security, resilience and availability remain non-negotiable. High-power environments are delivered within Ark’s secure, purpose-built facilities, backed by robust redundancy, operational discipline and decades of experience supporting mission-critical infrastructure.

Whether supporting AI training, inference, simulation or other compute-intensive workloads, Ark provides the foundations organisations need to operate with confidence today and adapt seamlessly to what comes next.
