Mission Statement Proposed Charter For Open Network Project Statement V#1.07 initial Charter draft resulting from May 16th 2013 Statement “The mission of Open Compute Networking Project is to create a set of networking technologies that are dis-agg regated and fully open allowing for rapid innovation in th e network space”

Mission Statement Dis-aggregated (*) “OCP Networking Project Update”, Carlos Cardenas, Santa Clara, CA USA, April 2015

Project Scope In-scope Hardware: The most Important Universal Form Factor “Common Motherboard” H/W Interconnects & Integration, Standards Based Cabling OpenRack + 19” Form Factors Energy Efficient Power Supplies & Cooling The most Important Since The Open Compute Project (OCP) is reimagining hardware, making it more efficient, flexible, and scalable 19” rack size  first rack standard that's designed for data centers, integrating the rack into the data center infrastructure

Project Scope In-scope Software: Recently added: Device Drivers, Boot Loader, Firmware, BIOS,… Open Linux OS’s Recently added: Developer Tools, Management Tools ReST (REpresentational State Transfer) API’s, SDN RESTful (REpresentational State Transfer) API (Application Programming Interface) DLs (Description Languages) are formal languages designed to provide a structured description of a RESTful web API that is useful both to a human and for automated machine processing

Project Scope Out of Scope Protocol stacks Virtualization Network architectures Network topologies

Project Scope Missions Open Switch Hardware Definition Leaf / Top of Rack Spine Open Switch Software Definition Operating System Independent (Linux Based) Open Boot Loader Bare Metal Provisioning (PXE, Uboot, ONIE, …) Network ASIC Chip Open Interface OCP Open Hardware Management ToR: Many organizations are now deploying modular data centers, ToR solutions complement rack-at-a-time deployment by simplifying and shortening cable runs and facilitating the replication of rack configurations Bare-metal provisioning is the process of installing an operating system (OS) or Type 1 hypervisor directly on a computer's hardware. Preboot eXecution Environment specification describes a standardized client-server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients U-Boot is an open source, primary boot loader used in embedded devices to package the instructions to boot the device's operating system kernel

Project Scope Key driver Common and Standard form factors Capex & Opex reduction Tier1 & Tier2 Multi-Vendor Implementation, Standards B ased 100% open source core, low-layer 100% standards based hardware implementation Independent Software & Hardware layers
