Google is sharing Open Rack v2.0, a proposed standard for a data center rack that runs on 48-volt power, with the Open Compute Project (OCP). The company is gathering feedback on the standard before final submission.
Google announced the contribution via a blog post today, noting that it has been collaborating with Facebook on it. If the standard is accepted, it will be Google’s first contributions to the OCP community.
Intended to bridge the transition from 12-volt to 48-volt architectures, Open Rack 2.0 has a modular design and a shallow form factor geared for high-density deployments in data centers with limited space.
Google says it has been deploying these types of racks since 2010 and has seen an increase in efficiency as well as fewer losses using the 48-volt payload as compared to a 12-volt solution.
The v2.0 standard also includes details for the design of 48-volt power shelves, high-efficiency rectifiers, rack management controllers, and rack-level battery backup units.
Google has said in the past that it may also work with the OCP on other areas such as storage management.
