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 Decision |
Design Justification |
Design Implication |
---|---|---|
Deploy a three-node vRealize Network Insight Platform cluster. |
Meets the availability and scalability requirements of up to 10,000 VMs and 2 million flows per day. |
The Management cluster must be properly sized 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. |
