On the desktop level, the WVOT deployed 1E PC power management software to 15,000-plus computers, spread among 75 agencies at 1,075 locations. Automating PC shutdowns will save the state an estimated $500,000 per year by 2012. The state is also exploring the use of virtual desktops to reduce energy consumption costs even more.
On the back end, the WVOT launched a consolidation and virtualization effort, migrating 17,000 of the 20,000 state agency employees from a variety of disparate email systems to a central email environment, resulting in a significant reduction of legacy servers.
The WVOT's 1E Nomad Enterprise deployment for delivering patches, software, and OS upgrades has saved the state from investing in hundreds of new servers for its remote locations. The rollout of centralized Web and voice services, videoconferencing systems, and desktop e-faxing has also increased worker productivity, while saving the state significant expenses through reduced travel.
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 percent 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 percent 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.
