Integrating OCP Racks with Single-Phase Immersion Cooling - ORv3 Ecosystem Implementation

Learn about the integration of Open Compute Project's ORv3 ecosystem with single-phase immersion cooling tanks in this 15-minute conference talk by Oriol Chavanel from Submer Immersion Cooling Solutions. Explore how immersion cooling and OCP standards combine to address the challenges of increasing chip densities and thermal design power (TDP) in modern datacenters. Discover the adaptations made to the original ORv3 specification for single-phase immersion tanks, resulting in higher density environments with improved operability. Examine key technological developments including the shift from 12V to 48V-54V power distribution, compact power shelf designs with denser PSUs, enhanced busbar capabilities in immersion environments, and simplified power cable management. Understand how these innovations contribute to increased thermal efficiency and heat reuse capabilities in datacenter operations.
