Different Model of ISE

[Neinei]

Hi experts,

Evening all, would like to check for 2 different model of ISE, can both of them be primary and secondary node with same role (PAN,PSN and MnT)?

Appreciate your response.

Thank you in advance.

@Neinei yes, but you'd need to take in to consideration that both models of ISE hardware support the same version of ISE, depending on which hardware is used, the older models do not necessrily support the latest ISE versions. Also consider the size of the cluster, you'd have to scale the cluster to the older hardware, which may not necessarily support the same size cluster as the newer hardware. https://www.cisco.com/c/en/us/td/docs/security/ise/performance_and_scalability/b_ise_perf_and_scale.html

Thank you Rob!

@Neinei:  Yes, it is possible.  That's what I am doing right now in a two nodes cluster environment.  Node1 is PAN/PMnT/PSN and node2 is SAN/SMnT/PSN.  In a small/medium environment, this is absolutely fine.

Thank you Adam!

Yes, two different ISE models can function as primary and secondary nodes with the same roles (PAN, PSN, MnT), as long as they're compatible and running the same verion.
