Increasing Data Center Efficiency by Using Improved High Density Power Distribution
High density server installations where racks can draw from 10 kW to 40 kW per rack place significant strains on the standard power distribution system found in large American data centers.
This increased rack power density is causing:
- Multiple branch circuits per rack, with corresponding breakers and cabling
- PDUs to become up to 30% of the floor space
- PDUs to become up to 30% of the floor weight loading
- More PDUs installed per IT rack, driving up capital costs
However, these problems are unique to North America. In Europe and the rest of the world the power distribution system is simpler and more efficient. This paper shows that it is practical to take the power distribution system used in the rest of the world and apply it to North American data centers to reduce cost, reduce weight, save floor space, and increase electrical efficiency.
