At NVIDIA GTC 2025, Solidigm showcased a unique demonstration of their liquid-cooled SSD technology. Though the demonstration might have created some confusion, it’s important to clarify that the SSDs themselves are not directly liquid-cooled. Instead, they utilize liquid cold plates mounted in the servers, which effectively manage the thermal output of these components.
Liquid-Cooled SSDs Introduction
The centerpiece of the demonstration was the Solidigm D7-PS1010 E1.S SSD, which features an innovative cooling design that allows both sides of its printed circuit board to be cooled via server cold plates. This move is significant as it simplifies the cooling process by integrating it directly into the server system.
Cooling Mechanism Explained
During the demo, the SSDs were inserted into cold plates that covered a section of their housing, allowing for effective heat dissipation without the need for liquid circulating through the drives themselves. This setup minimizes the potential risk associated with having fluid connections directly on the SSDs, such as leaks during maintenance.
As seen in the detailed diagrams presented during the demo, the design allows for optimized cooling without the complexities linked to direct liquid connection to the drives. This strategy is particularly relevant for the upcoming demand for powerful AI servers, given projected increases in power density—estimated to reach approximately 600kW per rack by 2027.
Importance of Advances in Cooling Technology
As server architecture evolves to manage higher thermal loads efficiently, designs like Solidigm’s will become essential. Removing traditional air cooling mechanisms, including fans and power shelves, not only frees up space within the racks but also enables a more fluid-based thermal management approach. The incorporation of liquid-cooled SSDs in future NVIDIA servers will likely enhance performance while accommodating the increasing energy demands of AI applications.
In conclusion, Solidigm’s demonstration at GTC indicates a shift towards more advanced cooling solutions for storage technologies, helping pave the way for the next generation of high-performance servers. This innovation will be vital in developing efficient and space-saving solutions for upcoming computing requirements.
