RP _ Rack & Power - Project (2026-04-08)

Why It Matters

Standardizing LVDC rack‑power interfaces will accelerate data‑center efficiency and reduce integration risk for hyperscalers and hardware vendors.

Key Takeaways

• OCP EMA summit scheduled April 29‑30 to discuss rack‑power developments.
• DCF team seeks community input on LVDC power distribution specifications.
• Joint white paper will define voltage, power quality, EMC, and safety interfaces.
• Participants from hyperscalers, GPU vendors, and Niobolt commit to collaboration.
• Aligning AC and DC standards improves protection coordination across data centers.

Summary

The meeting opened with a reminder about the upcoming OCP EMA summit on April 29‑30, where working groups will review the latest developments in rack‑power and related projects. Organizers emphasized the importance of attendance for stakeholders interested in shaping future data‑center power architectures.

The core agenda focused on the Data Center Power DCF team’s effort to develop a joint white paper on low‑voltage DC (LVDC) distribution. Participants were asked to contribute to defining specifications that bridge rack‑level hardware with broader power‑delivery systems, covering voltage thresholds, power‑quality metrics, and protection coordination.

Speakers such as Harry and Brian highlighted key technical challenges, including voltage and power‑quality standards, EMC considerations, and safety isolation at the rack‑power interface. Representatives from hyperscalers, GPU vendors, and Niobolt volunteered to join the workstream, underscoring industry demand for clear, interoperable guidelines.

If successful, the white paper will align AC and DC standards, streamline protection schemes, and reduce integration risk for next‑generation high‑density data centers. This collaborative approach promises faster adoption of LVDC architectures and more resilient power infrastructures across the ecosystem.
