  • 1.  Licensing question on cluster clearpass

    Posted Jul 31, 2015 12:40 PM

    I was wondering if this could work this way

     

    Let say we got a client which need to authenticate 9000 mac addresses

    This client would like a cluster for redundancy so that means 2 HW servers of clearpass

     

    It is possible to quote them 2 Clearpass of 5k for the cluster and at the end i would have 10k license.

     

    If one of the servers FAILS then i would have just 5k license but with the license burst this shouldnt be an issue

     

    Is htis scenario possible?

     

    Having a cluster for redundancy and also the 10k capacity in license i need and eve if i loose one of the Servers with the license burst ill still have time to get the server back even if it goes over 5k license in the only server i got up?

     

    Cheers

    Carlos

    Yes, that's a common scenario as long as the expectation is set that in a failover event, capacity and performance will be impacted.

    What kind of performance issues it could happens? at least what the end user will feel?

    Will the authentication take more time? for example if he is trying to connect to the wireless network it will take a couple of mins to authenticate? or what is it?

    Request processing time can go and there's a chance that you'll see
    timeouts.
