vRealize Network Insight communicates with the vCenter Server and the NSX Manager instances to collect metrics that are presented through various dashboards and views.

vRealize Network Insight is deployed as a cluster called the vRealize Network Insight Platform Cluster. This cluster processes the collected data and presents it using a dashboard. vRealize Network Insight also uses a Proxy node to collect data from the data sources, such as vCenter Server and NSX Manager, and send the data to the Platform Cluster for processing.

Design Recommendation

Design Justification

Design Implication

Deploy a three-node vRealize Network Insight Platform cluster.

Meets the scalability requirements of up to 10,000 VMs and 2 million flows per day.

The Management cluster must be sized properly as each vRealize Network Insight VM requires a 100% CPU reservation.

Deploy vRealize Network Insight Platform nodes of large size.

Large size is the minimum size supported to form a cluster.

None.

Deploy at least a single large-sized vRealize Network Insight Proxy node.

A single Proxy node meets the requirements in a new deployment. As the solution grows, additional Proxy nodes might be required.

vRealize Network Insight Proxy nodes cannot be highly available.
