The Open Compute Project initiative was announced in April 2011 by Facebook to openly share data center designs.[1][2][3]
Components include:
- Open Vault storage building blocks offering high disk densities, with 30 drives in a 2U Open Rack chassis designed for easy drive replacement
- A single voltage (12.5 VDC) power supply designed to work with 277 VAC input and 48 VDC battery backup
- Open Rack mechanical mounting system
- Open racks have the same outside width (600 mm) and depth as standard 19-inch racks, but are designed to mount wider chassis with a 537mm width (about 21 inches). This allows more equipment to fit in the same volume and improves air flow. Compute chassis sizes are defined in multiples of an OpenU, which is 48mm.
- Data center designs for energy efficiency, including 277 VAC power distribution that eliminates one transformer stage in typical data centers
