Virtual Mobility controller License stacking for scalability

    Hi Team,

    Just to check, for the VMC licenses, lets say I only have 20 x APs. Can I add 2 x MC-VA-10s instead of going for the MC-VA-50?

     

    I only saw that this is possible for MC-VA-1K, but not sure about the MC-VA-10 license tier. 

     

    Please advise thanks. 

    Ricardo

    As far as I know you should be able to stack (2) MC-VA-10 licenses on a single VMC-50 platform.

    Hi Jerrod,

     

    Thanks.

     

    So basically what you are saying, as long as I meet the 50 VM requirements then install 2 x MC-VA-10 licenses should be able to stack?

     

    Any links that you can share regarding this?

     

    I'm thinking the same thing but I cannot find any docs regarding this.

     

    Thank you.

    There's no explicit write up on that specific question. There's two elements in licensing for VMM/VMC:

     

    1. The provisioned virtual appliance resources (CPU/RAM/Disk). What is provisioned or configured dictates the virtual platform sizing outlined in the Virtual APpliance Installation Guides. More CPU/RAM/Disk raises the capacity of the appliance (just like buying a large controller)

    2. What the platform is licenses for.

     

    So in your case, with 20 APs, you provision an MC-VA-50 (because 20 won't fit on an MC-VA-10 and we don't provision an MC-VA-20), and then you install 2xMC-VA-10 licenses. This is like buying a 7010 controller that can support 32 APs, but only licensing it for 20 APs (because a 7005/7008 won't fit 20 APs). Exact same thing.

    Hi Jerrod,

     

    Thanks and understood. 

    So to summarize:

    1. Buy 2 MC-VM-10 licenses for the 20 APs

    2. Spin up VM but the resources should be allocated based on the MC-VM-50 specs. 

    3. After the MC-VM goes up, install the 2 licenses into the VM.

    4. Job Complete.

     

    Thanks.
