What is Energy Logic?
Energy Logic is a holistic approach for reducing data center energy use without compromising performance or availability. It is a vendor-neutral roadmap that starts with the IT equipment and cascades across all supporting systems.
Energy Efficiency Tops IT Concerns
Rising Energy Consumption
As data centers get packed with more complex equipment, more power is required to run these facilities.
Rising Energy Cost
Global electricity prices increased 56% between 2002 and 2006. The trend is expected to continue in the years to come.
Heightened environmental awareness
Regulations are pushing companies to lessen their footprint on the environment.

How is energy consumption categorized in a data center?
| Category |
Power Draw |
| Computing |
588 kW |
| Lighting |
10 kW |
| UPS and distribution losses |
72 kW |
| Cooling power draw for computing and UPS losses |
429 kW |
| Building switchgear/MV transformer/other losses |
28 kW |
| TOTAL |
1127 kW |
In a typical 5000-square-foot data center, demand-side computing equipment accounts for 52% of energy usage and supply-side systems account for the remaining.
Why is a distinction between demand-and supply-side systems important?
Reductions in demand-side energy use, cascade through to the supply side. For example, in the 5,000 sq. ft. (465 sq. m) data center* used to analyze energy consumption, a 1W reduction at the server component level results in additional 2.84W reduction in the power consumed.

What does “cascade effect” mean in Energy Logic?
Cascade effect is the energy savings that occur in each supporting system caused by reductions in energy consumption at the IT equipment level.
With the Cascade Effect, a 1 Watt savings at the server component level creates a reduction in facility energy consumption of 2.84 Watts.
Energy Logic is easy as 1…2…3
So what’s in it for me?
Reduces up to 50% in overall data center power consumption
Frees up to two-thirds of fl oor space
Saves up to two-thirds of UPS capacity and 40% of cooling capacity
