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, the DFW3 data center provides interconnection to other CyrusOne data centers in Texas and beyond.

  • Cooling Plant type and size – Closed loop, air-cooled chilled water system (N = 4.5 MW)
  • Cooling capacity per cabinet – 150 to 180 watts p/SF (average density)
  • Physical – 8′ high perimeter steel ornamental exterior fencing
  • Anti-tailgating system with raising and lowering arms at the vehicle entrance
  • Guards – Onsite guards man a dedicated Security Office at the main entrance (lobby) to the building
  • Electronic – A security system consists of various devices (card readers, badge readers, bio-readers, etc.) either permitting or denying access to various parts of the building
  • Access parameters are controlled through local onsite guards
  • Standards Compliance and Certifications – All local codes and standards are adhered to. CyrusOne standards and regulations are also in place for both safety and fire protection
  • CyrusOne Zero Water Consumption Cooling: No water is consumed to cool this facility (such as water towers or evaporative cooling).  Minimal amounts of water are used for humidification and facility maintenance. This facility uses highly efficient chillers, variable frequency drives, and energy-efficient CRAH units to achieve high-efficiency air-cooled chilling.  An average US data center of the same size typically consumes over 1 million gallons of water per month for cooling.
  • Regional Water Stress: The Allen area currently faces high water stress, which is projected to remain high in the future.  Unlike many other data centers, CyrusOne’s Dallas – Allen facility does not use water for cooling and is therefore insulated from this regional water risk, both current and future.

    • Regional Grid Greenhouse Gases: How much greenhouse gas does this facility’s local electrical grid emit while generating electricity?  (Useful for Location-based greenhouse gas reporting)
Greenhouse Gases 2004 2007 2012 2016 2018
MTCO2/MWh 0.644 0.568 0.518 0.458 0.423
    • The carbon intensity of the grid has improved by about 2.3% points per year over the last 14 years of published data. Reported by the US EPA eGRID for the ERCOT subregion (ERCT).
    • Regional Grid Renewables: What percentage of this facility’s local electrical grid is from renewable sources (wind, solar, biomass, hydro, and geothermal)?
Grid Renewables 2004 2007 2012 2016 2018
Percent from renewable sources 1.3% 2.7% 8.6% 14.5% 18.2%

This has been increasing by about 1.2% points per year over the last 14 years of published data.  Based on US EPA eGRID data for the ERCOT subregion (ERCT).
