Google joins Open Compute Project to drive standards in IT infrastructure
Google reported on their blog
“We’re excited to announce that we’re joining the Open Compute Project (OCP) to help drive standardization in IT infrastructure. More specifically, Google will contribute a new rack specification that includes 48V power distribution and a new form factor to allow OCP racks to fit into our data centers.
Energy efficiency in computing is a topic that has been near and dear to our hearts since the early days. We began advocating for efficient power supplies in 2003, and in 2006 shared details of our 12-volt architecture for racks inside our data centers — the infrastructure that supports and powers rows upon rows of our servers.
In 2009, we started evaluating alternatives to our 12V power designs that could drive better system efficiency and performance as our fleet demanded more power to support new high-performance computing products, such as high-power CPUs and GPUs. We kicked-off the development of 48V rack power distribution in 2010, as we found it was at least 30% more energy efficient and more cost effective in supporting these higher-performance systems.
Our 48V architecture has since evolved and includes servers with 48V to point-of-load designs, and rack-level 48V Li-Ion UPS systems. Google has been designing and using 48V infrastructure at scale for several years, and we feel comfortable with the robustness of the design and its reliability.”
