Data center energy costs as a percent of total revenue are at an all time high. In fact, energy costs are emerging as the second highest operating cost in the IT organization, behind labor. A typical one-megawatt data center consumes 16 million kilowatt-hours of electricity a year—roughly equivalent to the energy consumed by 1400 average U.S. households.

This white paper looks at two key ways that data center managers can improve end­-to-­end energy efficiency: by changing the voltage of power distribution and by taking advantage of new, high-efficiency, multi-mode uninterruptible power systems (UPSs).

This analysis shows that 400V AC power distribution offers a high degree of energy efficiency for modern data centers, significantly reducing capital and operational expenditures and total cost of ownership, compared to 600V AC and traditional 480V AC power systems. Recent developments in UPS technology—including the introduction of transformer­less UPSs with new energy management features— further enhance a 400V AC power distribution system to maximize energy efficiency.

The bottom line is new technology options and power distribution strategies can dramatically reduce the cost and carbon footprint of your data center. Down load this white paper from Eaton to learn more.

Is Your Data Center Draining Your Bottom Line?

Today, policy and business leaders are reaching a consensus that industry must address rising greenhouse gas (GHG) emissions, particularly in the data center. Leading enterprises are now turning to the practical challenge of determining how, how much, and at what cost to reduce emissions. In a recent white paper from IDC many companies are learning that their data center offers a means to both abate GHG and reduce costs with the right incremental capital investments.

The process of improving information technology and data center efficiency not only reduces GHG emissions but also reduces cost for the enterprise. This means that the savings or business value derived from improvements far outstrips the incremental capital costs of “greening” the datacenter. Green IT means business improvement. Firms that rank highest among the “Global 100 Most Sustainable Corporations in the World,” such as Amazon, Toyota, and Nike, have realized that focusing on limiting energy calories in the datacenter and elsewhere pays profitability dividends on the financial side. IDC research indicates that companies reducing their metric tons of carbon per datacenter workload by a factor of 55% also incurred 35% less cost per user session on a server.
