Overview
Watch Elizabeth Langer, Principal Technologist of Thermal at CPC and Travis Gaskill, Thermal Mechanical Engineer at Etched introduce the UQDv2 specification at the Open Compute Project Global Summit 2025. The Universal Quick-Disconnect (UQD) has played a significant role in the cooling ecosystem for GPUs and GenAI. In order to scale, and to further enable the adoption of liquid throughout the ecosystem, a workstream was established at the end of 2024 to develop a UQD Version 2.
The purpose of this workstream was to update the UQD-UQDB v1 specification such that gaps in requirements and performance are resolved, ambiguity is removed, and true interoperability is defined and achievable.
Key deliverables include unification of the UQD and UQDB as a singular specification, defined performance and interoperability testing requirements, and realization of a new mating configuration. Enhanced performance attributes and technical detail of the official v2 will be discussed, as well as guidance for working with participating vendors in the OCP ecosystem for immediate inquiries.
