Mix DN3-HW Pysical DNA app. with virtual in same cluster

[Alexander Rauch]

Hello,

our Cisco SE has told us some time ago that you can mix the new DNA Catalyst Center appliance (DN3-HW) with virtual appliances in the same cluster. Unfortunetely, I'm not able to find any official Cisco documentation about it and I doubt this is really true. Does anyone here know if this is possible to build a cluster with one physical appliance and two virtuals?

Thank you Alex

 - No official document found yet , but I am convinced this won't work; because HW clustering uses stuff like physical heartbeats for checks, which are incompatible with virtual appliances included too,

You cannot form a Catalyst Center cluster between on-prem and cloud (virtual) versions.

An on-prem HA cluster requires 3 physical appliances.

HA on cloud (virtual) is done with the tools provided by ESXi or AWS.

You can not mix hardware and virtual in cluster, they all to be same model
