Remote Collector nodes are a type of vRealize Operations nodes that only gather objects for the inventory, without storing data or performing analysis. Remote Collector nodes can navigate firewalls, interface with remote data sources, reduce the bandwidth across data centers, or reduce the load on the vRealize Operations analytics cluster1. Remote Collector nodes are not part of the analytics cluster, but they are members of the vRealize Operations cluster2.
Data nodes, Primary Replica nodes, and Primary nodes are all part of the analytics cluster and they store data and perform analysis. Data nodes have adapters installed and perform collection and analysis. Primary Replica nodes are replicas of the Primary nodes and provide high availability or continuous availability. Primary nodes are the initial and required nodes in vRealize Operations and manage all other nodes2. References:
