Explanation
ILM (Intelligent Lifecycle Management) is the Nutanix component responsible for monitoring data access patterns and triggering tiering events - moving hot (frequently accessed) data up to the SSD tier and demoting cold (infrequently accessed) data down to the HDD tier. This automatic tiering optimizes performance and capacity. Genesis (A) is the cluster startup and service management process. Cassandra (C) is the distributed metadata store. OpLog (D) is the write buffer that absorbs incoming writes before they are drained to the Extent Store - it is not responsible for SSD/HDD tiering decisions.
