ABSTRACT
Texas Advanced Computing Center (TACC) and Green Revolution Cooling (GRC) partnered to solve two common data center inefficiencies: the amount of energy spent cooling servers (relative to powering loads) and the inability to cool efficiently high-density, high-output devices such as blades, GPUs, and servers with over-clocked CPUs.
Using Green Revolution Cooling's liquid-submersion cooling solution, the CarnotJet system, TACC and GRC have been conducting efficiency and reliability studies with OEM servers for the past fifteen months with 100% uptime. Since April 2010, the self-contained system has demonstrated an 85% reduction in overall cooling energy while using 6 Watts or less per 100 Watts of IT. During over-clocking trials, the system successfully dissipated more than 200 Watts per socket while clocking current-generation Intel Xeon processors 35-60% over the base rate.
