Systems-integration is hard
OPNFV provides system integration for NFV as a community-led open-source effort.

Theme: “Run my VNF for real” Assemble a minimal set of base infrastructure to enable real-world VNF deployments
• Predictable performance – Deploy to bare metal• Validated – Functional testing, multiple test environments• Repeatable – Automatic deployment• Carrier-class – High availability

Getting ready to run a VNF on OPNFV
Prepare Deploy Run
• What hardware to run OPNFV on?
• Where to run OPNFV?
• What OPNFV software to install?
• How to deploy the OPNFV software?
• How to test the OPNFV deployment?
• How to run a VNFon the deployedOPNFV platform
![Page 12: Operating OPNFV](https://reader035.vdocument.in/reader035/viewer/2022062320/55ca5f82bb61eb1a3e8b459c/html5/thumbnails/12.jpg)
• Servers– >= 3 Control nodes
– >= 2 Compute nodes
– 1 Provisioning node (“jumphost”)(Centos 7, runs test infra and installer VM)
• Services– No additional services (e.g. DHCP)
available on subnets. Installers runservices that are required themselves
– Remote access for community members
– Lights-out-management (IPMI, PXE boot)

• OPNFV system software: main delivery vehicle– Bootable disk image (ISO format) to
install jumphost
– Jumphost drives installation of OPNFV system
• Alternative– Install script (“deploy.sh”) to
automatically install the jumphost from repositories

Deployment in a Nutshell
• Document your node roles, addresses etc.
• Cable your servers and configure any networking gear needed
• Deploy (and optionally customize) your jumphost (“build server”)
• Kick-off control nodes, compute node deployment, network setup
• Download images and upload into Glance
• Boot instance, test connectivity
• Modify setup to meet your needs
• Have a nice day

Install and Deployment - Concept
• Installer setup, parametrization of environment, setup and deployment of OPNFV can be automated
• Details of individual deployment steps differ by installer (e.g. Foreman, Fuel)
Put node into build mode with BMC reboot
PXE-boot nodes
Install host OS and associated control infra (Puppet etc.)
Install roles specific software on nodes

Deploy and Configure InstallerSetup Installer

Cinder create a volume
Create a new SSH key-pair and add it to Nova
Choose a VNF image and upload the image to Glance
Create a tenant network + router
Spawn VNF instance and link to criteria set above
Ensure VNF spawned (horizon, nova list, or ssh)
Check connectivity: Ping your VNF

Summary
• OPNFV – Systems-integration as an open, meritocratic, community effort
• Starting point (“Arno” release):
– “dotadiw” approach to get started
– Lab/developer focused first release
– “Run my VNF for real” mind set: Deploy to bare metal with HA
– Instantiate cross-project CI/CD tool chain
– Distributed lab infrastructure
• Multiple ways to leverage and participate in OPNFV: Run your VNF, get your use-cases/test-cases implemented, articulate your requirements
– User uptake to determine OPNFV’s success: Can common merit be achieved quickly enough to achieve industry acceptance?

Closing thoughts
• NFV base infrastructure is a natural candidate for open-source and community driven development
– “Hard work” – “Low on IP”, … but integration is still an art
• NFV base infrastructure has a strong systems-integration aspect:Choose vs. Choice
– Systems-integration is about picking, choosing and Trust
– Open-Source is about creating choice and recognizing merit created
… Could a meritocratic approach provide for a solution?
• Create and Maintain one Open Platform for NFV – adhere to “dotiadiw” – Verification (test driven) definition of OPNFV target system state moving forward?
