10 strategies to reduce DC's energy use by up to 74%

by CXOtoday News Desk    Aug 30, 2012

Green DCEmerson Network Power has introduced Energy Logic 2.0, a vendor-neutral roadmap of 10 strategies that can reduce a data center’s energy use by up to 74 percent. The approach, detailed in a new e-book, updates the original Energy Logic, introduced in 2007, to incorporate the advances in technology and best practices that have emerged in the past five years. The company also launched the Energy Logic 2.0 Cascading Savings Calculator, an online tool that allows data center managers to calculate the approximate energy savings they would capture by employing strategies in the updated approach.

With the inclusion of new technologies and best practices, Energy Logic 2.0 illustrates how the energy consumption of a 5,000 square-foot data center could be cut by up to 74 percent using available technologies. It accomplishes this by leveraging the cascade effect, the cornerstone of the Energy Logic approach.

The cascade effect quantifies how savings at the IT component level are magnified in the supporting systems, recommending an overall approach that focuses on optimizing the efficiency of core IT systems to drive the greatest savings.

What’s New in Energy Logic 2.0
Energy Logic 2.0 shows how the energy consumption of the base data center can be reduced from 1,543 kW to 408 kW. Key strategies, such as high-efficiency server components, power architecture improvements, and temperature and airflow management have been updated to reflect recent technological advances. The base data center takes into account the rapid adoption of server virtualization. Server consolidation and virtualization are now treated as one strategy because they typically happen in concert. Information and Communications Technology (ICT) architecture is highlighted as an emerging best practice that delivers energy savings by optimizing IT and networking architecture. Data center infrastructure management (DCIM) is incorporated throughout the Energy Logic strategy, because it provides the visibility and control required to fully leverage multiple Energy Logic strategies, including server power management, virtualization, power architecture, and temperature and airflow management.

In addition to the cascade effect, Emerson Network Power has quantified the “reverse” cascade effect: the total energy wasted by stranded capacity.

Using the Cascading Savings Calculator
Data center managers can use the Cascading Savings Calculator to explore the impact Energy Logic 2.0 strategies might have on their facility. Users enter their compute load and facility PUE, then adjust sliding scales for nine strategies to show percent utilization. Based on this information, the calculator will approximate a strategy’s impact on compute load, PUE, and total energy and cost savings.
