Single-Phase Immersion Cooling Study of a High-Density Storage System

In this paper, a standard air-cooled high-density storage system is reengineered to demonstrate the use of single-phase immersion cooling. It is successfully demonstrated that the storage systems can be designed to support single phase immersion cooling while supporting hot swap and cooling redundancy requirement like an air-cooled system.

In addition, the system can operate reliably for facility coolant supply temperature as high as 40°C. The resulting power consumption of the pump was less than five percent of the total IT power. 

Finally, the proposed cooling solution may help mitigate acoustic vibrational issues for drives often encountered in air-cooling solution as the solution is virtually silent in operation.
