Open Compute Project (OCP)

The Open Compute Project (OCP) is an industry consortium, launched by Facebook in 2011, that publishes open-source specifications for data center hardware — servers, racks, power shelves, network switches and, increasingly, liquid-cooling and rack-power architectures for AI clusters. OCP-compliant designs strip out proprietary enclosures and standardize rack width, busbar power delivery and cabling, letting operators source hardware from multiple vendors and cutting both capital cost and deployment time versus traditional OEM servers. Members include Meta, Microsoft, Google, Nvidia and most major server and networking vendors, and OCP's annual Global Summit has become a venue where AI infrastructure specs — including Nvidia's high-power rack designs for GB200/GB300-class systems — are standardized industry-wide. Colocation operators increasingly need to support OCP rack formats and higher busbar voltages, up to 800V DC in newer designs, to win hyperscale and AI tenants who build exclusively on OCP hardware.
