Hi @gupta_anand
No, it is not possible to use the Cisco SNS-3715-K9 and SNS-3615-K9 appliances together in a high availability (HA) configuration for Cisco Identity Services Engine (ISE). Cisco ISE requires that all nodes in an HA deployment (or distributed deployment) use the same hardware model. This is because the performance and capacity of the appliances must match to ensure consistent behavior and failover capabilities.
The SNS-3715 and SNS-3615 appliances have different hardware specifications, such as CPU, memory, and storage, which makes them incompatible for HA or distributed deployments. To set up HA, you would need to use identical hardware models (e.g., all SNS-3715 or all SNS-3615).
If you are planning an HA or distributed deployment, ensure that all nodes are running the same ISE version and are on compatible hardware. If you are considering upgrading or replacing hardware, consult Cisco's compatibility and migration guides for ISE to ensure a smooth deployment.
Hope This Helps!!!
