This Excel-based calculator provides a first-order estimate of the magnitude of the energy savings based on improving the efficiency of any one or more of the elements (UPS, AC-DC and DC-DC power supply) involved in powering a rack of servers
We developed a total cost of ownership tool that can be used to estimate the value of energy savings at the rack level from improvements to UPS, power supply, and internal component efficiencies in servers. This type of analysis ensures that buyers and sellers of power supplies and UPS's are able to give greater consideration to energy efficiency in the purchase process.
Uninterruptible Power Supplies (UPS), Front-end AC-DC power supplies and DC-DC converters are three important conversion processes for powering of servers and other IT loads in a data center. Improving the efficiency of one or more of these conversion processes can significantly improve the overall energy efficiency of a data center.
