Cut power costs with DC power

to get additional power from the local utilities. Increasing the efficiency of existing systems could also allow companies to continue to use existing buildings and still expand datacenter capacity.

A high-voltage power system like that from Validus requires substantial installation and investment, including running large diameter cabling from the utility pad outside into the datacenter, installing the 575-to-48-VDC converters for each rack, and converting servers to 48 VDC. However, saving 50 percent or more on power over many years represents a big return. For companies that are unable to increase datacenter capacity by buying more power capacity, turning to DC may be the only solution.
