Nitto Kogyo OCP ORv3 Direct-Liquid-Cooling Rack Adopted at DRIL AI Validation Facility
Редакция ЦОД:Главное
Nitto Kogyo’s OCP ORv3-compliant rack for direct-liquid-cooled, high-density deployments has reportedly been adopted at DRIL, an AI infrastructure validation facility in Inzai operated by MC Digital Realty. The facility is described as a validation site for NVIDIA advanced rack-scale AI servers.
- Nitto Kogyo’s direct-liquid-cooling OCP ORv3 rack has reportedly been adopted at MC Digital Realty’s DRIL validation facility in Inzai.
- The cited report characterizes the deployment as Japan’s first adoption of a fully OCP ORv3-compliant rack.
- The case highlights integrated rack, power-delivery and liquid-cooling requirements for high-density AI infrastructure.
- The 150 kW-per-rack figure is described in technical commentary and is not confirmed as DRIL’s installed or operating rack load.
- No deployment quantity, facility IT capacity, investment value or commercial-operating status was disclosed.
Nitto Kogyo’s direct-liquid-cooling, high-density OCP ORv3 rack has reportedly been selected for DRIL, an AI infrastructure validation facility in Inzai operated by MC Digital Realty, a Mitsubishi Corporation subsidiary.
DRIL is described as a validation facility for NVIDIA advanced rack-scale AI servers. According to the cited report, the installation represents the first adoption in Japan of a fully OCP ORv3-compliant rack. Nitto Kogyo is also said to accept individual orders for ORv3-compliant racks.
The deployment is relevant to the shift in AI infrastructure design away from conventional air-cooled, 19-inch-rack-centric procurement. Higher-density AI systems require coordinated evaluation of rack architecture, 48V DC power distribution, liquid-cooling pipework, leak-management measures and heat-rejection design. Adoption in a validation environment could support further testing of these integrated requirements for domestic AI deployments.
The source discusses Nitto Kogyo’s ORv3 rack in the context of supporting thermal loads of up to 150 kW per rack. That figure should not be read as the measured operating load of the units installed at DRIL, nor as a confirmed capacity of the facility. The reported deployment does not disclose the number of racks installed, DRIL’s total IT capacity, investment value, operational start date or whether the equipment is in commercial operation.
The adoption signals growing domestic implementation and validation of open-rack specifications for high-density AI infrastructure in Japan. As AI server thermal loads increase, rack design, 48V DC power delivery and direct liquid cooling increasingly need to be assessed as an integrated system; however, a deployment at a validation facility does not establish the scale of commercial data-center adoption.
