Inside the Open Compute Project Server

What this post added

This post details the development and launch of the Open Compute Project (OCP) server, a custom-designed hardware solution by Facebook engineers and partners. It outlines the technical specifications and design choices for the server's motherboard (supporting AMD and Intel CPUs, with a direct power supply interface and removed unnecessary features), power supply (achieving 94.5% efficiency with a novel 48VDC backup system to replace traditional UPS), chassis ('vanity-free' design for utility, ease of assembly, and weight reduction), rack ('triplet' design for efficient server density and networking port utilization, with serviceability features), battery cabinet (99.5% efficient DC backup system using 48VDC strings, replacing traditional UPS), and thermal design (taller chassis with larger fans for reduced energy consumption).
