Increase capacity Viprion

Hi folks,

 

I have 2 Viprion, each Viprion with 2 Blade. I need only configure HA between Viprion but is not necessary HA in the same Viprion, I only need increase the capacity in each Viprion with this 2 Blades. Is necessary configure in the same Viprion, one 1 IP management for each Blade? or is not necessary. When, I configured HA between Viprion, the Blade Active change of state to Passive in the all Blade in the all Viprion.

 

Thanks
