Power distribution for data centre server racks
OCP-compliant, cost and space-saving
HARTING has developed connectors for power-saving and space-saving rack power supply systems within the framework of the Open Compute Project (OCP) for data centres.
The Open Compute Project (OCP) is an open community for collaboration on efficient data centre hardware design, initiated by Facebook in April 2011, and also includes Microsoft, Apple, IBM and Intel.
HARTING offers connectors for rPDU (tapped rack power distribution unit) connections and power shelf connections.
rPDU/PDU connection
rPDU (tapped rack power distribution unit) connection solution using plastic dustproof and waterproof Han-Eco® connectors, a new open source, next-generation hyperscale cloud-based hardware development model developed by Microsoft in collaboration with the OCP community. Adopted by Project Olympus. The pluggable system significantly reduces installation and maintenance work compared to direct wiring and reduces costs as it prevents incorrect wiring. It also saves space and reduces power consumption by up to 50% compared to conventional connectors.
Features

Power Shelf Connection
Han® ORV Power connectors are OCP's Open Rack v3 compliant connectors, developed by HARTING based on the plastic dustproof and waterproof Han-Eco® connectors OCP offers the recommended data centre design ‘Open Rack’ free of charge and Open Rack version 3 (ORV3), which is starting to be deployed worldwide from early 2023.Open Rack uses a power supply system with centralised power supply power shelf units, making it completely wireless. As a connector partner of OCP, HARTING led the creation of the Open Rack v3 specification.

On-Demand Web Seminar
The current capacity required for connectors is approaching its limit due to the introduction of AI servers and increased data usage, and significant power loss is becoming an issue. HARTING has developed a connector for data centres that saves about a quarter of the space and achieves more than three times the current capacity compared with conventional IEC connectors (CEE connectors). Connector technology that improves data centre uptime and reduces power costs will be introduced along with a case study of a major US-based data centre.
