Facebook announces next-generation Open Rack frame

What this post added

This post announces the next-generation Open Rack frame, a collaborative initiative with Microsoft and the Open Compute Project (OCP) community. It addresses increasing power demands from AI and networking by introducing a new architecture based on Open Rack. Key technical contributions include enabling greater sharing between Microsoft and Facebook through a common OCP rack architecture, providing a flexible frame and power infrastructure for diverse solutions, and enabling new thermal solutions like liquid cooling manifolds and door-based heat exchangers. The post details the advantages of 48V power delivery over 12V for efficiency and handling high dI/dt, and outlines the goals for the Rack & Power project and Advanced Cooling Solutions subproject, including a converged rack frame, flexible power shelf, universal AC power interconnect, pluggable DC power shelf output interconnect, and battery backup systems.
