NTT Global Data Centers, the third largest carrier-neutral data center operator globally, provided updates on its newest, 240-megawatt data center campus located in Mesa, Arizona, part of the Phoenix market.
Phoenix Campus – NTT Global Data Centers
NTT’s Phoenix data center campus is located at 10302 E Elliot Road, Mesa, Arizona, which is ~27 miles from downtown Phoenix. The campus will have seven data centers on the 102-acre site. At full build-out, NTT’s Phoenix campus will comprise 240 megawatts of critical IT load across 1.5 million sqft of space.

Connectivity
NTT’s Phoenix campus will be interconnected by a fiber ring allowing for tenant connectivity and growth across the seven data centers. Additionally, multiple meet-me-rooms throughout the campus will allow for physical diversity within each building.
Power
NTT owns the substation at its Phoenix campus which will deliver 480+ megavolt amperes (MVA) of power.
Phoenix (PH1) – NTT Global Data Centers
Phase 1 of the campus, Phoenix PH1, will be a two-story building with 36 megawatts of critical IT load. Specifically, NTT is building the data center with six vaults, each with 6 megawatts of power capacity. Every vault will be ~21k sqft, which together form a data center with 127k sqft of data hall space.
In May 2021, NTT officially broke ground on Phoenix PH1, with expectations being set for completion in 2022.
Connectivity
Finally, three diverse fiber entry points and two meet-me-rooms will provide Phoenix PH1 with access to multiple cloud service providers, carriers, and internet service providers (ISPs). Correspondingly, these service providers will be able to offer dark and lit services.
