The rack architecture uses 48V and enjoy the open source through the Open Compute Project. Google and Facebook have collaborated on a new rack architecture (open rack standard) that uses 48 V, and was released under the auspices of the Open Compute Project (OCP).

Unlike other OCP projects Β that mostly benefit Hyperscale data centers, Open Rack v2 is presented in a “modular format shallow” that allows the deployment of high-density dedicated servers in a smaller size, something which would be especially useful in installations with limited space.

The specifications for Open Rack have made their way through the OCP Incubation Committee and shared with the community. Later this year, the architecture will be presented to the OCP Foundation for review and if accepted, will become Google’s first contribution to the project.

Google was a newcomer to the OCP, having joined the non-profit organization in March 2016. During the announcement at the Summit of Open Compute in California, the company said it was working to bring its ecosystem energy distribution of 48 V to the masses.

The chain 48V offers greater efficiency than traditional solutions 12V, and Google said earlier that managed to increase its energy efficiency by 30 percent by eliminating those multiple deployed transformers in data centers, which helps save millions of dollars in electricity bills.

The latest version of Open Rack also includes specifications for a system 48V Li-Ion UPS rack level.

“Our contributions to Open Rack Standard are based on our experiences that promote architecture 48V with both our internal teams and industry partners, incorporating design experience we have acquired in recent years,” says an entry in the blog the technical program manager of Google, Debosmita Das and senior technical manager, Mike Lau.

“In addition to the mechanical and electrical specifications, the new Open Rack Standard V2.0 is based on the design of 12V above. A holistic approach that includes details for the design of shelves 48V, high efficiency rectifiers, driver management is needed rack units and battery backup rack level. “

Google expects the standard enable an easier transition from 12V to 48V and help save costs related equipment throughout the industry.

The new standard will be officially presented next week during the OCP Engineering Workshop at the University of New Hampshire week.
