Emerson Network Power, a business of Emerson, has introduced Energy Logic 2.0, a vendor-neutral roadmap of 10 strategies that can reduce a datacentre’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 datacentre 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 datacentre 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 optimising the efficiency of core IT systems to drive the greatest savings. In addition to the cascade effect, Emerson Network Power has quantified the “reverse” cascade effect: the total energy wasted by stranded capacity.
“Energy Logic 2.0 clearly shows there still are great opportunities to optimise the datacentre,” said Jack Pouchet, Vice President of Business Development and Director of Energy Initiatives, Emerson Network Power. “Energy efficiency remains a priority, and a new generation of management technologies that provide greater visibility and control of datacentre systems has arrived. The datacentre industry is better positioned than ever to make a serious impact in reducing overall datacentre energy consumption.”
Datacentre 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 utilisation. Based on this information, the calculator will approximate a strategy’s impact on compute load, PUE, and total energy and cost savings. The strategies datacentre managers can explore are Low-Power Components, High-Efficiency Power Supplies, Server Power Management, ICT Architecture, Virtualisation and Consolidation, Power Architecture, Temperature and Airflow Management, Variable Capacity Cooling and High-Density Cooling.
By trying out the Cascading Savings Calculator, datacentre managers can see how implementing each strategy – and varying degrees of each strategy – might impact their savings.
