NTT’s foray into liquid cooling technology marks a significant leap forward in the data center landscape. With the launch of two key initiatives in Japan, NTT is not just keeping pace with industry trends but is actively shaping the future of cooling solutions. The Data Center Trial Field in Noda City, Chiba Prefecture, is set to become a hub for innovation, collaboration, and practical testing of liquid cooling systems. This facility, spanning 105 square meters and boasting a capacity of 75kW, aims to tackle the myriad challenges that currently plague liquid cooling technology, primarily the lack of standardization across manufacturers.
In the world of data centers, where efficiency is king, the differences in liquid cooling specifications can create a minefield for operators. NTT’s initiative is a breath of fresh air. By creating an environment where different liquid cooling devices and servers can be operated concurrently, the facility will serve as a collaborative platform for various stakeholders. This includes data center operators, equipment manufacturers, IT vendors, and research institutions. The goal? To foster joint verification efforts that can ultimately lead to the development of solutions that meet the diverse needs of customers.
What’s particularly noteworthy is NTT’s commitment to not only verifying the performance of liquid cooling technologies but also addressing the construction challenges posed by differing domestic and international standards. This proactive approach could pave the way for smoother integrations of liquid cooling systems into existing infrastructures. The facility will also delve into optimizing chilled water temperatures and flow rates, enhancing overall data center efficiency.
Meanwhile, NTT Communications is taking a different but equally compelling approach with its testing of two-phase direct-to-chip cooling in an air-cooled data center in Tokyo. This innovative system, which circulates an insulating refrigerant in a liquid/gas manner, aims to boost cooling capabilities without the need for extensive modifications to existing setups. This is a game-changer for facilities looking to enhance their cooling capacity while minimizing downtime and disruption.
The collaboration with Mitsubishi Heavy Industries and NEC Networks & System Integration Corporation highlights the importance of partnerships in driving technological advancements. The demonstration testing set to begin in December will not only validate the effectiveness of two-phase cooling but also contribute to broader sustainability goals, such as reducing CO2 emissions and energy consumption in data centers.
With NTT’s Green Nexcenter colocation service, which supports direct-to-chip cooling, already making waves, the momentum is building. As these initiatives unfold, they will likely inspire other players in the industry to rethink their cooling strategies. The implications of NTT’s work could extend far beyond Japan, influencing global best practices in data center cooling and efficiency.
In an era where data centers are under increasing pressure to operate sustainably and efficiently, NTT’s dual approach to liquid cooling technology could very well set the standard for the industry. As companies grapple with rising operational costs and environmental responsibilities, these innovative cooling solutions may offer a lifeline, proving that sometimes, the answer lies in going against the grain.
