Super Micro Computer, Inc. expanded its Rear Door Heat Exchanger (RDHx) portfolio on July 15, 2026, to strengthen its end-to-end liquid cooling solutions for high-density AI and HPC infrastructure. The expanded portfolio offers flexible cooling capacities, providing data center operators with a path to liquid cooling for both new and legacy facilities. The solutions support cooling chill door capacities from 10kW up to 120kW at the door level, with a maximum of 240kW of cooling capacity at the rack-level.
The ten RDHx models can be deployed as a primary liquid cooling solution or integrated with Supermicro's Direct-to-Chip (D2C) liquid cooling technologies. This integration is part of the company's Data Center Building Block Solutions (DCBBS), which delivers validated rack-scale infrastructure, intelligent management software, and global deployment services. The solutions are compatible with standard EIA, ORv3, and MGX racks, allowing for seamless integration into existing data centers without major facility modifications.
Key Specifications and Benefits
The RDHx solutions are designed to increase compute density and cooling efficiency for AI and HPC workloads. The portfolio includes features aimed at simplifying deployment and maximizing reliability in data center operations.
| Feature | Description |
|---|---|
| Cooling Capacity | 10kW to 120kW per rack; max 240kW at rack-level |
| Compatibility | Standard EIA, ORv3, and MGX racks |
| Power Options | DC-powered models for rack busbars; AC-powered models for broad compatibility |
| Management | Redfish, SNMP, web-based management, and SuperCloud Composer (SCC) |
Charles Liang, president and CEO of Supermicro, stated that the expanded RDHx portfolio helps customers realize the benefits of liquid cooling with a range of capacities enabling more efficient data center operations. The solutions allow customers to design and deploy validated rack-scale cooling solutions tailored to their facility requirements, infrastructure constraints, and workload demands.
Deployment and Monitoring
Supermicro's RDHx solutions offer several deployment and monitoring capabilities to support data center operations. The units mount directly to standard racks for rapid deployment in new data centers or retrofits, eliminating the need for dedicated facility chilled water or extra hardware. Reliability features include intelligent fan control, N+1 redundancy, and anti-condensation protection for continuous operation.
Operators can monitor infrastructure in real time using Redfish, SNMP, web-based management, and Supermicro SuperCloud Composer (SCC). These tools allow for the tracking of temperature, pressure, flow rate, and pump status. The DCBBS portfolio aims to simplify procurement, reduce integration risk, and reduce Time-to-Online (TTO) by providing accelerated systems, rack-scale integration, facility power and cooling, and deployment services.
How will the expanded RDHx portfolio influence Supermicro's market share against competitors offering alternative liquid cooling solutions?
What impact will the ability to retrofit legacy facilities have on the overall adoption rate of liquid cooling in the data center industry?
How might the introduction of these high-capacity cooling solutions affect the pricing strategies for AI and HPC infrastructure services?
