The first study of the energy savings potential of Asetek RackCDU was made public by Henry Coles of Lawrence Berkeley National Laboratory at the Silicon Valley Leadership Group’s 2013 Data Center Efficiency Summit. The 6-month study investigated Asetek RackCDU D2C™ (Direct-to-Chip) technology that directly cools the hottest components in a server (CPUs and memory) with hot or cold water and the balance of the server with data center air. The study demonstrates that hybrid liquid cooling solutions deliver substantial site-level energy savings.
