Diablo 400 Project: Rack and Power
Currently three companies have worked together to provide a high-level overview of the Diablo 400V architecture. The goal is to standardize items such as, high voltage connectors and
View DetailsData centers are increasingly adopting 400V DC rack power distribution as an alternative to traditional AC systems, driven by the need for improved efficiency, reliability and cost-effectiveness.
As AI workloads continue to drive up data center power demands, both AC and 400V DC rack power distribution present compelling solutions for improving efficiency and scalability. While AC infrastructure remains dominant, its inefficiencies are becoming more apparent, particularly in high-power-density AI data centers.
The high-level proposal for a 400Vdc disaggregated power rack enables an improved solution compared to prior 12Vdc and 48Vdc solutions and aims to encourage industry alignment and commonality in several areas:
In this exclusive Q&A, Vicor contends that ±400-V DC power distribution to AI racks in data centers is inevitable. The demand for increased compute density. An evolution to ±400-V DC distribution to next-generation AI/ML supercomputer racks to meet that demand. Challenges and solutions in making the move to ±400-V DC distributed power.
