The University of California, San Diego's (UCSD's) California Institute for Telecommunications and Information Technology (Calit2) recently developed Cool-Flo, cooling technology that could improve energy efficiency and enable higher-performance computing.
The technology was installed in the Calit2 server room as part of ongoing research into energy-efficient data centers led by UCSD professor Tajana Simunic. The Cool-Flo servers monitor processor, random access memory, and chipset temperatures, in addition to the total power consumed by the system while running normal research loads. Cool-Flo is a server-agnostic, rack-based, direct-to-the-chip and leak-free liquid-cooling system that can be used to cool any server, and is based on rocket-cooling technology.
Although the technology was initially developed as an energy-efficient solution, the researchers found that liquid cooling enabled faster processors and increased rack densities, both of which provide improved high-performance computing. "Cool-Flo is a good fit for Calit2’s server needs given the institute’s commitment to reducing the energy intensity of campus [information technology] and improving energy efficiency," says UCSD's Steve Harrington.
