vRealize Operations Manager communicates with all management components in both regions of the SDDC to collect metrics about the operations of the objects that these components handle.

In a multi-region Software Defined Data Center (SDDC), 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). This topology provides high availability, scale-out capacity up to sixteen nodes, and failover.

2 remote collector nodes in each region. The remote collectors communicate directly with the data nodes in the vRealize Operations Manager analytics cluster. For load balancing and fault tolerance, two remote collectors are deployed in each region.

Each region contains its own pair of remote collectors whose role is to ease scalability by performing the data collection from the applications that are not a subject of failover and periodically sending collected data to the analytics cluster. You fail over the analytics cluster only because the analytics cluster is the construct that analyzes and stores monitoring data. This configuration supports failover of the analytics cluster by using Site Recovery Manager. In the event of a disaster, Site Recovery Manager migrates the analytics cluster nodes to the failover region.

Logical Design of vRealize Operations Manager Multi-Region Deployment
vRealize Operations Manager deployment include an analytics cluster and a group of remote collectors. You monitor all SDDC management products that are used in this VMware Validated Design.

The vRealize Operations Manager nodes run on the management pod in each region of SDDC. For information about the types of pods, see Pod Architecture.
