「At the KDDI Telehouse Shibuya Data Center, we tested the introduction of water-cooling technology to efficiently cool high-heat-output GPU servers, established guidelines for facility design and operation specialized for water cooling, and applied them at the Osaka Sakai Data Center.」
We advanced research into immersion cooling and energy conservation by establishing facility design and operation guidelines for water-cooling technology and applying them at the Osaka Sakai Data Center. - FY2024AdvancedAnnual report
「We are conducting joint research and development with Mitsubishi Heavy Industries and NEC Networks & System Integration on server cooling using an immersion cooling system that uses liquid to cool IT equipment, aiming to reduce the power consumed for cooling by 94% and develop sustainable data centers that contribute to decarbonization.」
We gave concrete form to the immersion cooling pilot by moving from an expected approximately 35% reduction in total data center power consumption to joint research targeting a 94% reduction in server cooling power consumption. - FY2023-Q1AdvancedAnnual report
「We will also introduce containerized data centers equipped with immersion cooling systems that use liquid to cool IT equipment, with the aim of reducing CO2 emissions across the KDDI Group.」
We advanced the introduction of containerized data centers using immersion cooling systems from the pilot stage to a policy of implementing them at data centers. - FY2022-Q1First statedAnnual report
「We began a pilot project in June this year with the aim of socially implementing, in fiscal 2022, a small data center equipped with an immersion cooling system that uses liquid as the cooling medium. ... Power consumption at the data center is expected to be reduced by approximately 35%, helping address the high power consumption of data centers while also potentially reducing CO2 emissions.」
We began a pilot project with Mitsubishi Heavy Industries and NEC Networks & System Integration using a small data center equipped with an immersion cooling system. Social implementation in fiscal 2022 and an approximately 35% reduction in power consumption are expected.
