Data Center Efficiencies Coming Full Circle to DC, Liquid Cooling

1. Throwing around terms like liquid cooling and DC power, the next generation in data center efficiencies may have a decidedly retro look, said Roger Schmidt, Chief Engineer for Data Center Energy Efficiency at IBM. Additionally, data centers will incorporate higher voltages and more renewable energy sources, said Schmidt, an engineer based in IBM’s Poughkeepsie, New York, office. For his efforts in identifying data center efficiencies — arguably one of the hottest business sciences today — Schmidt was recently named an IBM technical fellow, a prestigious honor achieved by only 218 IBM employees since the 1960s. Schmidt was a driving force in IBM’s “Big Green” project. That retro look Early binary data centers were liquid cooled. Most contemporary data centers are air-cooled, but liquid cooling provides better performance per watt, Schmidt said. Another data center improvement may come from delivering higher voltage to servers. “Putting the electricity through transformers wastes energy ... (Read Full Article)
