In a typical AC system, the voltage is normally transformed, rectified and inverted five times before it is reaches the servers. The DC system rectifies and converts the utility supply twice to provide 48VDC direct to standard DC powered servers. The DC system provides a more efficient system because it reduces losses from multiple conversions, produces less heat, and reduces the amount of cooling needed.
The DC system eliminates the need for power distribution equipment normally found in an AC system such as PDU’s and UPS and therefore eliminates the need for tons of copper, steel, plastic and lead acid batteries from the environment.
New Opportunities for Industry Players.
The GE and Validus DC system provides key industry players new opportunities to deliver efficient solutions to their clients. Sun Microsystems' datacenter consulting practice can incorporate the new offerings within their clients datacenter solutions. "The need for increased productivity and improved efficiency within the datacenter continues to drive innovations across the industry", said Amy O'Connor, vice president of Marketing, Sun Services. "Sun can leverage the solutions offered through the GE and Validus alliance and our Sun Netra™ carrier-grade systems, as a new option for our customers when recommending datacenter designs."
Additional savings from lower equipment costs and real estate help to reduce the total cost of ownership of the electrical distribution equipment by about 50%, while providing 99.9998% reliability.
For a typical 2.5 MW data center with a 2N system, the GE and Validus DC Data Center System will provide the following benefits compared to an equivalent AC system:
• Use 25% less energy, saving nearly 14 million kWh per year, equivalent to an average of $3.3 million per year in annual energy savings, assuming $0.14 per kWh.
• Reduce the initial cost of the electrical distribution equipment by about 50% and the installation cost by about 20-40% depending on site conditions and power density.
• Reduce the real estate required for infrastructure equipment by about 50% - equivalent to a saving of about 7,000 ft2 or $3.2 million per year assuming $500 annual cost per square foot.
• Provide savings equivalent to $33 million over 5 years.
• Improve reliability as the system has fewer single points of failure. The system has fewer power conversions and transformations, and therefore produces less heat output. As a result, the DC system is half as likely to fail within a five-year period compared with an equivalent AC system, and provides 99.9998% reliability.
