Digital Realty has launched a new liquid-to-chip cooling colocation offering.

The company this week announced a direct liquid cooling (DLC) offering, available in 170 Digital Realty data centers globally.

Digital said the offering includes a range of mechanical solutions, such as rear door heat exchangers (RDHx) and DLC, offering power densities ranging from 30-150kW per rack and beyond.

“The combination of RDHx with DLC effectively doubles the power densities that can be supported,” the company said, “empowering businesses to tackle the escalating demands of modern IT infrastructure and accelerate the adoption of AI by enterprises, through private, cloud and hybrid solutions.”

Digital launched an Air-Assisted Liquid Cooling (AALC) offering, based on rear door heat exchangers on racks, in August 2023. At the time, the company said the service, which offered densities of up to 70kW, was available in 28 markets across North America, EMEA, and Asia Pacific.

The company said the new offering has deployment options available in more than half of Digital Realty's data centers worldwide, with plans to ‘expand support to additional sites and to leverage existing infrastructure’ to meet emerging AI requirements.

"We're proud to align with our customers in evolving their infrastructure to support this cutting-edge liquid-to-chip technology, enabling them to land and expand their deployments efficiently and redefine what's possible in the digital age. With this cutting-edge liquid-to-chip cooling technology, we're not just setting a new standard for high-density deployment support, we're revolutionizing the digital infrastructure landscape," said Chris Sharp, Digital Realty CTO.

Scott Tease, VP and general manager of HPC and AI for Lenovo ISG, added: “By working with great partners like Digital Realty, we're helping enterprises of any size on their AI journeys. The Lenovo-Digital Realty partnership forms a critical cornerstone of the hybrid AI vision, enabling organizations to harness the full potential of emerging technologies to deliver innovation faster.”

Lenovo's role in the announcement hasn't been detailed.

The company has previously trialled liquid cooling at a number of data centers including in France and Singapore. Digital is also an investor in Colovore, which operates an all-liquid-cooled data center in California.

Equinix announced plans to support direct-to-chip liquid cooling at 100+ data centers in December 2023.
