3 Open Compute Project Torpedo Design Concept 3 Overview When data center design and hardware design move in concert, they can improve efficiency and reduce power consumption. To this end, the Open Compute Project is a set of technologies that reduces energy consumption and cost, increases reliability and choice in the marketplace, and simplifies operations and maintenance. One key objective is openness the project is starting with the opening of the specifications and mechanical designs for the major components of a data center, and the efficiency results achieved at facilities using Open Compute technologies. One component of this project is a concept storage server that integrates with Open Rack, controlled by a standard SAS expander card. The Torpedo Design Concept is 2xOpenU high and can accommodate " drives arranged in a 3 x 5 array. Its form factor is compatible with the Open Rack compute node and designed to occupy similar space in an Open Rack innovation zone. Initial design target is direct cabled to an off the shelf SAS expander. The design is capable of accommodating integrated backplanes as a future design option. 3.1 License As of April 7, 2011, the following persons or entities have made this Specification available under the Open Web Foundation Final Specification Agreement (OWFa 1.0), which is available at Facebook, Inc.
