vRealize Operations Manager communicates with all management components in all regions of the SDDC to collect metrics which are presented through a number of dashboards and views.
Logical Design
You deploy a vRealize Operations Manager configuration that consists of the following entities.
3-node (medium-size) vRealize Operations Manager analytics cluster that is highly available (HA) in the hub. This topology provides high availability, scale-out capacity up to sixteen nodes, and failover.
2 remote collector nodes in each ROBO. The remote collectors communicate directly with the data nodes in the vRealize Operations Manager analytics cluster. For high availability and fault tolerance, two remote collectors are deployed in each ROBO.


Each ROBO contains its own pair of remote collectors whose role is to ease scalability by performing the data collection from the applications and periodically sending collected data to the analytics cluster.

Physical Design
The vRealize Operations Manager nodes run on the . For information about the types of clusters, see Workload Domain Architecture in ROBO.
