DNAC single node vs three node cluster difference.

[angus21]

Is there any difference between a single node DNAC vs a three node cluster DNAC ?

I am already aware that HA(high availability ) needs a three node cluster . Other than that what else can I find different. ?

single node DNAC vs a three node cluster DNAC =

Single means you know by now - there is no redundancy and all in 1 Box, if that is failed, you do not have redundancy

DNAC 3 node cluster give more high availability and auto-recover ( also patch management is easy if you have cluster)

There is another deployment also there called DR - this is 1+1 +Witness (this request 2 DNAC and 1 Witness VM to Monitor DR)
