Regions must be connected to each other. Connection types could be point-to-point links, MPLS, VPN Tunnels, etc. This connection is different according to your environment and is out of scope for this design.

The region interconnectivity design must support jumbo frames, and ensure that latency is less than 150 ms. For more details on the requirements for region interconnectivity see the Cross-VC NSX Design Guide.

Provide a connection between each ROBO site and the hub that is capable of routing.

The vRealize Operations Manager remote collectors, vRealize Log Insight, vRealize Automation proxy agents, and vRealize Business data collector require connectivity back to the hub.

For provisioning and single pane of glass monitoring the connection between the hub and ROBO site must be up.


Ensure that the latency between the ROBO sites and the hub is less than 150 ms.

A latency below 150 ms is required to ensure successful provisioning of workloads in the ROBO site.
