Components include:

* Server compute nodes included one for [[Intel]] processors and one for [[Advanced Micro Devices|AMD]] processors. In 2013, [[Calxeda]] contributed a design with [[ARM architecture]] processors.<ref>{{Cite web |title= ARM Server Motherboard Design for Open Vault Chassis Hardware v0.3 MB-draco-hesperides-0.3 |author= Tom Schnell |date= January 16, 2013 |url=http://www.opencompute.org/wp/wp-content/uploads/2013/01/Open_Compute_Project_ARM_Server_Specification_v0.3.pdf |accessdate= July 9, 2013 }}</ref>

* Open Vault storage building blocks offer high disk densities, with 30 drives in a 2U Open Rack chassis designed for easy [[disk drive]] replacement. The 3.5 inch disks are stored in two drawers, five across and three deep in each drawer, with connections via [[serial attached SCSI]].<ref>{{Cite web |title= Open Vault Storage Hardware V0.7 OR-draco-bueana-0.7 |author= Mike Yan and Jon Ehlen |date= January 16, 2013 |url= http://www.opencompute.org/wp/wp-content/uploads/2013/01/Open_Compute_Project_Open_Vault_Storage_Specification_v0.7.pdf |accessdate= July 9, 2013 }}</ref> Another design concept was contributed by Hyve Solutions, a division of [[Synnex]] in 2012.<ref>{{Cite web |title= Hyve Solutions Contributes Storage Design Concept to OCP Community |work= News release |date= January 17, 2013 |url= http://ir.synnex.com/releasedetail.cfm?ReleaseID=733922 |accessdate= July 9, 2013 }}</ref><ref>{{Cite web |title= Torpedo Design Concept Storage Server for Open Rack Hardware v0.3 ST-draco-chimera-0.3 |author= Conor Malone |date= January 15, 2012 |url= http://www.opencompute.org/wp/wp-content/uploads/2013/01/Open_Compute_Project_Storage_Server_for_Open_Rack_Specification_v0.3.pdf |accessdate= July 9, 2013 }}</ref>

* Mechanical mounting system: Open racks have the same outside width (600 &nbsp;mm) and depth as standard [[19-inch rack]]s, but are designed to mount wider chassis with a 537mm537&nbsp;mm 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 48mm48&nbsp;mm, slightly larger than the typical [[rack unit]].

* Data center designs for energy efficiency, include 277 VAC power distribution that eliminates one transformer stage in typical data centers. A single voltage (12.5 VDC) power supply designed to work with 277 VAC input and 48 VDC battery backup.<ref name="Stanford" />

* On May 8, 2013, an effort to define an open [[network switch]] was announced.<ref>{{Cite web |title= Up next for the Open Compute Project: The Network |date= May 8, 2013 |author= Jay Hauser for Frank Frankovsky |work= Open Compute blog |url= http://www.opencompute.org/2013/05/08/up-next-for-the-open-compute-project-the-network/ |accessdate= July 9, 2013 }}</ref> The plan was to allow Facebook to load its own [[operating system]] software onto the switch. Press reports predicted that more expensive and higher-performance switches would continue to be popular, while less expensive products treated more like a [[commodity]] (using the [[buzzword]] "top-of-rack") might adopt the proposal.<ref>{{Cite news |title= Can Open Compute change network switching? |author= David Chernicoff |work= ZDNet |date= May 9, 2013 |url= http://www.zdnet.com/can-open-compute-change-network-switching-7000015141/ |accessdate= July 9, 2013 }}</ref>

A similar project for a custom switch for the [[Google platform]] had been rumored, and evolved into the [[OpenFlow]] protocol.<ref>{{Cite news |title= Facebook Rattles Networking World With ‘Open Source’ Gear |date= May 8, 2013 |author= Cade Metz |work= Wired |url= http://www.wired.com/wiredenterprise/2013/05/facebook_networking/ |accessdate= July 9, 2013 }}</ref><ref>{{Cite news |title= Going With the Flow: Google’s Secret Switch to the Next Wave of Networking |date= April 17, 2012 |author= Steven Levy |work= Wired |url= http://www.wired.com/wiredenterprise/2012/04/going-with-the-flow-google/ |accessdate= July 9, 2013 }}</ref>
