SAN JOSE, CA, July 7, 2025 – Super Micro announced that its BigTwin Server, powered by 4th and 5th Gen Intel Xeon Scalable processors, has earned immersion cooling certification. Tested with dielectric liquids and immersion tanks, the system meets performance and reliability benchmarks as a certified immersion server. It also complies with Open Compute Project (OCP) material compatibility standards for immersion environments, supporting energy-efficient data center deployments.
“Supermicro’s collaboration with Intel is a long-standing, strategic association that combines Intel’s cutting-edge processor technologies with Supermicro’s high-performance building block solutions, including AI, HPC, intelligent edge/IoT, networking, and storage,” said Ray Pang, senior vice president of technology enablement, Supermicro. “Certifying our BigTwin server for immersion cooling within the Intel and OCP guidelines and practices ensures customers that their Supermicro server will be fully functional when immersed in the specified liquid.”
Supermicro servers can lower Power Usage Effectiveness (PUE) by leveraging immersion cooling technology that eliminates the need for air-based cooling systems. By submerging factory built fanless servers in dielectric fluid, heat dissipates reducing the energy required for cooling solutions like CRAC and CRAH units. This approach reduces cooling overhead and enables denser compute density without increasing the thermal load. By removing internal server fans, it also lowers IT equipment power consumption, improving Power Usage Effectiveness (PUE). As a result, data centers using immersion servers can achieve PUE values near 1.05, helping to reduce both energy consumption and environmental impact.
“Intel worked hand-in-hand with Supermicro, along with key tank and fluid providers, to certify their multi-node BigTwin system, passing the rigorous testing that immersion cooling requires,” said Rami Khouri, Intel VP, platform engineering group GM, data center hardware engineering. “This first-of-its-kind solution, known as Intel Data Center Certified for Immersion Cooling, ensures that Supermicro customers can be confident that the BigTwin systems will continue to perform as expected and give its data center customers a clear path to sustainable, efficient cooling in the AI era.”
The Open Compute Project (OCP) immersion cooling guidelines promote hardware interfaces, fluid specifications, and operational best practices that simplify the integration and maintenance of immersion-cooled systems.
“We are grateful for the role that Supermicro has played within the OCP Community, and eager to see what the future holds,” Michael Schill, senior director of community, OCP foundation. “The leadership and industry expertise contributed by the Supermicro team has been instrumental in driving innovation forward, not only within the Immersion Subproject, but across the entire OCP Community.”
Supermicro’s BigTwin immersion servers, combined with Intel’s ADDL immersion cooling, use thermally conductive dielectric fluid to dissipate heat. This reduces energy consumption versus air cooling and meets OCP standards for energy-efficient data center operations.
The certified system tested consisted of:
- BigTwin SuperServer SYS-221BT-HNTR
- Four hot-pluggable systems (nodes) in a 2U form factor. Each node supports the following:
- Socket E (LGA 4677) support 5th/4th Gen Intel Xeon Scalable processors Intel C741
- 16 DIMM Slots supporting up to 4TB of memory; ECC RDIMMs up to DDR5-5600
- 2 PCIe 5.0 x16 (LP) slot;
- Tool-less support
- Internal PCIe 4.0 for 2 x4 M.2 NVMe support onboard
- Optional M.2 (22×80) HW RAID1 NVMe Boot Controller via SCC-A2NM2241G3-B1
- Network connectivity via AIOM (OCP 3.0 compliant)
- 3000W Redundant Power Supplies Titanium Level (96%+); Shared Power Design
Intel’s ADDL immersion solution, developed with Supermicro, has helped advance OCP immersion cooling standards, defining parameters for safe operation and component reliability in immersion environments. As AI and HPC workloads drive higher power densities, data centers require operative cooling solutions. Immersion cooling meets this need by managing heat and enabling data centers to achieve PUE levels near 1.0. These advancements provide a foundation for scaling sustainable, high-performance computing infrastructure in the future.
