Re: OpenStack (+ Quantum Deployment) Scenarios

  Thread Previous • Date Previous • • Thread Next
Thank you Dan for shedding light on this matter. However, there is something concerns me and a lot of other people trying to deploy OpenStack is that most Servers has 2 NICs which creates a problem because your Demo is a great one but the necessary hardware is just not always met !
I have been struggling to find a solution out of it, can you suggest some please ?

Hi,
The Quantum Admin Guide indicates that you can choose to combine all services onto a single node, or have separate nodes: http://docs.openstack.org/trunk/openstack-network/admin/content/services.html
I will update the text to indicate that that the main reason to use a dedicated network gateway node is if you plan on having VMs send substantial amounts of traffic through that node, and thus would not want that CPU usage to conflict with other openstack services running on your controller node.

    Can someone please enlighten us about the goods of having a
    separated network node ?
    I honestly work in production envirnoments (over 30 nodes) and i
    really give computing resources more credit than networking ones !

    Am i doing it the wrong way here ?

    Hi Openers,
    One doubt i have is like, as we see in the demo setup in the
    Quantum Admin guide available in openstack.org
    <http://openstack.org>, we have Network Node as a seperate
    physical node connected to Controller Node and Compute Node.
    But i see that the openstack community who is actively using
    Folsom is not discussing more on this kind of setup.
    Not sure if iam missing any key information on this like that the
    Network Node setup may not be widely used in current deployment
    scenarios or it is too early to use Network Node as a seperate
    physical host for openstack.
    Open comments on this will be more helpful for openstack
    community to understand better on the features of folsom.
    regards,
    balaji

        Hi Skible,

        Can you please send me below configuration files of three
        setups you have mentioned.

          * ovs_quantum_plugin.ini (For controller and node)
          * nova.conf (For controller and node)

        Thanks in advance


        Regards,
        Veera.

            Hello Stackers !

            I am currently trying to create pictures of my OpenStack
            deployment architecture as a part of my OpenStack Folsom
            install guide
            <https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst>
