As the next generation of AI servers emerge, the demand for power and cooling solutions is set to skyrocket. With workloads pushing the limits of the latest chipsets and accelerators, the thermal design power (TDP) of chips is increasing, making efficient cooling more critical than ever.
Introducing the QCT QoolRack Sidecar Solution
The QoolRack Sidecar Solution employs a state-of-the-art liquid-to-air cooling cycle to manage the heat generated by high-performance servers. Designed for seamless integration with traditional air cooled data centers, it delivers powerful cooling without requiring a complete overhaul of existing data center infrastructure.
The QoolRack Cooling Cycle:
- Hot coolant is transferred from the IT rack to the radiator.
- 14 rear-mounted fans cool the liquid by dissipating heat into the surrounding air.
- The cooled coolant flows to the pump units, passing through an inline filter to remove impurities.
- The purified coolant is then returned to the IT rack, ready to repeat the cycle.
Comprehensive Design
The QoolRack Sidecar Solution is meticulously designed to ensure efficient cooling and ease of maintenance.
Key components include:
- 44 OU High Structure: Accommodates a 1U power shelf, a human-machine interface (HMI), an inline filter, a 4U reservoir and pumping unit (RPU), 14 hot-swappable fans, and a 1-inch FD83 quick connect coupling.
- Power Shelf: Powers the entire system, including fans and pump units.
- Human-Machine Interface (HMI): Allows users to monitor the cooling status in the data center.
- Inline Filter: Prevents impurities from entering the cold plate.
- 4U Reservoir and Pumping Unit (RPU): Contains 2+1 pumps and a DC-SCM board to monitor cooling status and ensure redundancy in case of pump failure.
- Hot-Swappable Fans: 13+1 fans dissipate heat from the radiator to the air, cooling the coolant.
- Quick Connect Coupling: The 1-inch FD83 coupling enhances serviceability and efficiency when connected to the IT rack.
Innovative Cooling Solution
The QCT QoolRack Sidecar Solution offers up to 70 kW of cooling capacity (based on NVIDIA GB200 NVL72 requirements) and can be seamlessly integrated alongside any traditionally air-cooled server rack. This innovative solution eliminates the need for extensive data center infrastructure overhauls, making it a cost-effective and efficient choice for existing data centers.
Smart Monitoring and Self-Adjustment
The QoolRack Sidecar Solution features a built-in smart monitoring mechanism that enables pump speed and fan speed self-adjustment as well as leakage detection. This ensures optimal performance and reliability across diverse workloads, reducing the management effort from the data center operator. In conclusion, the QCT QoolRack Sidecar Solution represents the future of liquid cooling, offering unparalleled efficiency, reliability, and ease of maintenance. As data centers continue to evolve, solutions like QoolRack will be essential in meeting the increasing demands of high-performance computing environments.
