Explanation

The Monitoring and Troubleshooting (MnT) node is responsible for collecting, aggregating, and storing all log data from the ISE deployment. This includes RADIUS accounting records, authentication logs, syslog messages from network devices, and detailed troubleshooting reports. Because the MnT node continuously ingests and retains large volumes of log data over time, it requires significantly more storage than any other ISE persona. The Policy Service node (A) processes AAA requests in memory and does not store large amounts of data. The Primary Administration node (B) stores configuration and policy data, which is comparatively small. The Platform Exchange Grid (D) (pxGrid) is a context-sharing service and has minimal storage requirements. Cisco's own sizing guides consistently call out the MnT node as requiring the most disk space.
