Emerson's data centers globally, the facility has exceeded expectations for availability, capacity and efficiency. In addition to playing a major role in Emerson's consolidation efforts, another goal for the 35,000 square-foot data center was to use the same best practices and technologies that Emerson Network Power recommends to customers. The first best practice employed was using Emerson Network Power's Energy Logic roadmap to guide each decision that was made to ensure efficient energy use and to optimize space, power and cooling. Energy Logic leverages the cascade effect that occurs when lower energy consumption at the component and device level is magnified by reducing demand on support systems. Following all Energy Logic steps allowed the data center to operate at a 39 percent more efficient level than the average data center operating today. In fact, Energy Logic played a major role in the data center becoming LEED certified (Leadership in Energy and Environmental Design) by the U.S. Green Building Council. The project surpassed its green building-goal of achieving LEED Silver recognition and instead won LEED Gold based on sustainability practices, the materials used, indoor environmental quality, energy use and design innovation. One notable example was deploying a 100-kilowatt solar array, which has provided the equivalent of powering 18 homes since the solar array began operating. Other than through virtualization, the highly flexible capacity of the data center is a result of designing the facility to scale three-fold. The extra space won't be needed immediately, however. Between virtualization and increased equipment efficiency, there is enough raised floor space to handle the next 3-5 years of capacity and growth expectations. The Emerson Global Data Center, which meets the criteria that The Uptime Institute has set for a Tier III facility, has been always-on for the past three years. "We had an F4 tornado that went through and ripped the St. Louis airport apart, came within a mile of our data center and took out a lot of power to the area," Fritz said. "But we didn't see one minute of downtime." The 100 percent availability experienced by the data center is credited to multiple layers of electrical redundancy, as well as a building design that can withstand an 8.0 earthquake.
