AI is now the big data centre disruptor. It is driving up demand for power and is changing the format of data centres. In that kind of environment, you have to be very dynamic and collaborative
Tom Absalom, Engineering Director
No. PRISM scales to the facility. We work with hyperscale, colocation and enterprise operators, on everything from a single infrastructure upgrade to the construction of a new campus.
Mitie has over 20 years in critical environments, with deep engineering, security and facilities expertise across hyperscale and colocation data centres, and a proven track record alongside some of the most demanding operators.
Data centres are mission-critical environments underpinning digital infrastructure. They demand exceptionally high power capacity and resilience, built-in redundancy and failover, and uptime of 99.9% or higher, a combination that makes them fundamentally different from most built environments and is exactly what PRISM is designed for.
