Back to the Future - DC Powering Your Data Center
Live Q&A session will immediately follow
Lawrence Berkeley National Laboratory is working with over 20 firms in a demonstration to show that large
energy savings are possible by eliminating multiple power conversions that typically occur in data centers
resulting in energy efficiency gains. A traditional AC distribution system was set up alongside the new DC
distribution system at a Sun Microsystems facility using components loaned by industry partners.
Intel and Sun Microsystems modified servers to directly accept high voltage (380V) DC power.
Preliminary results are indicating facility-wide energy savings of 10 to 15 percent when considering
electrical and HVAC savings, with potential for even greater savings.
