CyrusOne’s Chandler / Phoenix data center has completed the first phase of its 1,000,000-square-foot Phoenix data center campus—one of the largest and most energy-efficient data centers in the United States.

Key Features

The Nation’s Biggest Data Center Campus

In June 2012, CyrusOne broke ground on a 57-acre campus slated to be nearly 1 million square-feet of space in Chandler, Arizona – the largest of its kind.

The first building, which was commissioned near the end of 2012, has 38,000 square feet of raised floor and another 38,000 square feet came online in 2014. There is also room for seven or eight more buildings on this campus, making the CyrusOne Phoenix data center campus very unique.

Energy Efficient Power & Cooling

CyrusOne’s Phoenix data center I leverages efficiency measures never before utilized in this capacity, and offers powerful cost-reduction opportunities for the enterprises that colocate their data and servers here.

To begin, the roof of the Phoenix data center I is V-shaped, sloping toward the middle. This is beneficial for two reasons: one is the green element –directly replenishing the ground water. The other is the containment element – water is passed away from the building. The V-shaped roof design also allows for a highly-efficient cooling model at the Phoenix data center will allow CyrusOne to achieve a low PUE.

In addition, the data center itself is being designed for an average draw of 250 watts per square foot, with the ability to go up to 1,000 watts per square foot for customers with extremely dense specialized equipment. That means a data center built to suit newer gear that has a smaller footprint but higher power utilization.

Massively Modular® Engineering

CyrusOne’s Massively Modular data center engineering is specifically designed to achieve optimal flexibility for even the largest scale deployment and build out.

CyrusOne can build out new data halls in just 12-16 weeks through aggressive sourcing and a just-in-time focus to meet customer demand.

The Massively Modular model frees customers from being confined by time, space, and/or flexibility constraints often found in other data center providers.

Conveniently Located in a Data Center Safe Zone

The Phoenix data center I is well suited for Fortune 500 companies that require robust data center infrastructure for mission-critical applications and want to locate it in an area that is generally considered one of the safest in the country—free from natural disasters including seismic activity, tornados, and hurricanes.

The Nation’s First National Internet Exchange

With CyrusOne’s National IX (Internet Exchange), customers can configure a virtual on-net platform from a multitude of carriers and providers, allowing optimal flexibility and interconnection with anyone at any connected facility and to the cloud.

As part of CyrusOne’s National IX platform, this Phoenix data center provides interconnection to other CyrusOne data centers.
