Mostly we are using Three types of Deployment method used -
ISE Small Deployment
ISE Medium Deployment
ISE Large Deployment
ISE Small Deployment -
• (2) nodes in the same DC
• All nodes run all personas.
• All nodes run all services.
• Designed for a small LAN or a low-latency WAN.
• General recommendation is no more than 300ms round-trip latency between nodes.
• Small Network Split Deployment
• Same as above, but the two nodes are in different Data Centers
ISE Medium Deployment --
• Requires anywhere from 3 to 8 Nodes.
• Node 1: Primary Administration and Secondary Monitor.
• Node 2: Primary Monitor and Secondary Administration
• Node 3 – 5: Dedicated PSN
ISE Large Deployment --
• (x) Nodes
• Node 1: Dedicated Administration
• Node 2: Secondary Administration
• Node 3: Primary Monitoring
• Node 4: Secondary Monitoring
• Node 5+: Dedicated PSNs.
• May include separate load balancers or node groups.
• PSN placement is typically determined by volume in any given geographical region
