2011 Green 15 winner: Xiolink Data center operator Xiolink fully embraced the concept of sustainability in building its new data center in St. Louis: Rather than constructing an entirely new facility, the company opted to renovate a historic downtown building -- previously home to the St. Louis Dispatch -- that had been vacant for nearly a decade.
Xiolink deployed an array of state-of-the-art technologies and green computing practices to make its data center energy efficient. For example, the facility's HVAC systems draws on outside air as temperature permits and uses variable frequency drives to adjust the speeds of pumps, motors, and fans, making the act of cooling 40% more energy efficient than with traditional CRAC systems.
The facility boasts hot and cold aisles, along with PVC curtains to prevent air from mixing, and its UPS system, the Eaton 9395, operates at 94-plus percent efficiency, requiring less power and running cooler than standard models, while taking up 50% less floor space.
For power distribution, Xiolink went with a power plug-in raceway, a reliable modular system that allows the operator to add extra circuits and change power without delays.
