Hi

 

If Prism Central is just a single VM currently, you can expand it to three VMs.  This increases both the capacity and resiliency of Prism Central. Scale out Prism Central is supported on AHV and ESXi clusters only.

 

Thanks

Hi @randyramandani,

In case of flow, If one Prism Central VM goes down in scale-out deployment Flow visualization may stop working (no new flows will be displayed and only old ones will be shown), as AHV hosts send flow data only to one Prism Central VM and there is no automatic failover.

hi team, thanks for the answer,

so if i already have isolated connection from category A to category B and my single prism central going down, my isolated connection still work?

@randyramandani yes, when Prism Central is down you lose the ability to manage flow but any existing rules are still implemented. This allows networking to continue as normal during upgrades and other maintenance operations.
