Learn about Cumulus Linux

For our next meetup we're going to revisit a topic that we've already touched on several times: Software Defined Networking. There's a lot going on in this space at the moment and we're luckily to have lots of people involved in this space in the Triangle. Sean Cavanaugh, of Cumulus Networks, is going to give us an overview of Cumulus Linux, a Linux for switches, and show off its integration with configuration management tools. 

This is how Sean describes his talk:

An overview of Cumulus Linux and how it plays into the modern network.  Cumulus Linux is a Linux Distribution based off Debian Wheezy that can run on bare metal switches.  What is a bare metal switch?  What is Software Defined Networking (SDN)?  We will cover all that and what Cumulus Linux is and how you can leverage existing DevOps tools (Chef, Puppet, Ansible, etc) to automate not just your servers but your network.  As with all Linux distributions: Fly, Be Free.

If you don't know much about software defined networking Sean will get you up to speed. If you feel you already know it all from our previous speakers on the topic, Sean's talk should still be of interest with the hands on look at how to manage a switch with configuration management tools.

Here's more on Sean:

Sean Cavanaugh is a Support Engineer that wears many hats for Cumulus Networks, the company behind Cumulus Linux.  Prior to Cumulus Networks Sean worked for Cisco Systems and was a CCIE (#40514) consulting for the US Army.  Sean has a Computer Engineering Degree from Clemson University and has been actively involved in the networking industry since he was a little kid helping his dad interopt IPv6 and IPv4.  Sean lives with his wife, future daughter (coming Oct 20th), dog and two cats in Chapel Hill, NC.

We're at WebAssign for this meetup. Doors open at 6:45 pm. Drinks and pizza will be provided.

Looking forward to seeing everyone there.

    Regarding SDN there are many solutions working in many different areas. OpenDayLight (ODL) is the opensource SDN controller for OpenFlow although it is designed to work with future protocols.

    http://www.opendaylight.org/software/editions

    ODL has got a tremendous community going and some interesting "add-ons" that many aren't aware of.

    Take a look IBM's DOVE or NEC's VTN.... both of which are included in either the OpenDaylight Virtualization or Service Provider versions (all are open source & free).

    NEC's Virtual Tenant Network (VTN) supports VLAN and VxLAN, Distributed ODL servers for scalability as part of a really nice model for SDN.

    I came away from reading NEC's VTN impressed and plan to try it out eventually.

    It was my 1st visit to the devops mtgs. One suggestion would be to try to have at least 1 or 2 white boards present for "social" technical discussions <g>. It would help spur conversation & learning & get people interacting with each other in the Q&A that ensues.

      That's a good suggestion Brian. That's likely going to depend on if hosts have white boards they can make available, but we can see how to possibly make this happen for future meetings.

    Was not able to make it. Was this one recorded?

      Future events hosted at Bronto can more easily be recorded now, or even live-streamed (Google Hangout?), as we've got a permanently mounted HD camera on the wall now.

    Awesome, the way SDN was presented shows it's no longer a science experiment and you can start running it in the data center. I'm now trying to figure out how we can make this happen in our data center.

    Cumulus++. Mark, if you need pizza sponsors for this Ansible would like to cover it. Let me know!

      Consider it done Michael. Greg reached out and we're getting the details taken care of.

      Thanks for sponsoring the pizza, Michael! Very happy for Ansible's success and Ansible sharing that success with the local community.

I'm surprised by the level of growth I've seen since becoming an organizer, it's given me more confidence in my abilities.
