Meta's ORv3 "HPR Next" Ecosystem Solution for High Power AI Architectures

Explore a high-level overview of Meta's development of Open Rack v3 (ORv3) High Power Rack (HPR) "Next" solutions in this 14-minute presentation by Glenn Charest, Mechanical Engineer at Meta. Learn about the rack and power challenges facing future AI architectures and Meta's innovative solutions to address them. Discover the evolution from HPR v2 (featuring 12kW PSU and BBUs) to HPR v3 (Side Power Rack) and HPR v4 (HVDC Side Power Rack), understanding why each solution is necessary for meeting the dynamic power demands of AI systems. Gain insights into the fundamental building blocks of each design, including power supply units (PSU), battery backup units (BBU), capacitor backup units (CBU), rack form factors, busbar designs, and methods of power transmission between racks. This presentation serves as the first summit-wide introduction to HPR Next, a development that has generated significant interest throughout the Open Compute Project community.
