Question on Sizing Master Controller when Local Redundancy in place

Hello's

I have a question on sizing the Master controllers (An Active master and a Standby master) when there are 2 Local Controllers for Local Redundancy. No AP's will terminate on the Master.

For Sizing of the Locals, I understand that a single controller should be able to support all AP's in the case of a Local failure and should be sized as such.

Question is with the Master. How are the masters sized? Assume an environment with 400 AP's, one could opt for two 7210's as the locals for instance. What about the master? What is the criteria for sizing the master? As it does not terminate AP's can a smaller controller e.g. a 7010 be used for instance?

 

Thanks,

You should use the same size or larger in some cases. Take a look at the WMS
scaling information:

Hi Friend,

 

Master is not only responsible for managing and pushing the configuration, it also take care about ARM & CM, IDS hence it require high speed processing capacity therefore it is advisable to choose a controller with high hardware as a Master.

 

Aruba would not recommend 700X series as a master because of it's hardware limit, it is designed to work either as a standalone or a branch office (Local) controller.

 

Hope you got some more clarity.

 

Please feel free for any further query on this.

 

Cheers,
Venu Puduchery,
