5. 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

6. 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

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

8. 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

9. 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
