MQD is a quick disconnect coupling standard tailored by NVIDIA for next generation AI data center liquid cooling systems. Primarily built for the Vera Rubin architecture platform, it serves as the core component supporting million scale GPU compute deployments.
Compliant with the latest NVIDIA specifications, Netonx MQD complements the UQD standard with a differentiated focus on efficient in node connections within rack level liquid cooling distribution systems. Featuring a planar sealing design, it delivers low leakage per mating cycle and is optimized for high density data center environments with enhanced flow dynamics for higher flow rates and lower pressure drop.
