The virtual infrastructure of the ROBO SDDC consists of a consolidated cluster in a ROBO location, and a hub that is responsible for provisioning workloads and monitoring the SDDC.

Figure 1. Consolidated Cluster  Logical Design


A Consolidated SDDC design contains one availability zone and has one distributed switch. The switch is connected to the management applications in the SDDC, the NSX components, and tenant workloads.


Management Cluster

Management cluster run the virtual machines that manage the SDDC in the hub. The cluster includes the vRealize Automation for provisioning and vRealize Operations Manager components for monitoring all regions. For more information on the management pod, see VMware Validated Design for Software-Defined Data Center.

Consolidated Cluster

The consolidated cluster runs the virtual machines that manage the ROBO site and connect to the central management components in the hub. These components include vCenter Server, vSphere Update Manager, NSX components, remote collectors for vRealize Operations Manager, vRealize Log Insight, vSphere proxy agents for vRealize Automation, data collector for vRealize Business, and other management components.

All management, monitoring, and infrastructure services are provisioned to the consolidated vSphere cluster which provides high availability for these critical services.

NSX services enable North-South routing between the SDDC and the external network, and East-West routing inside the SDDC.

The consolidated cluster also hosts the tenant workloads in the site. Workloads run customer business applications that have varying SLAs.

Note:

If you must scale your ROBO site beyond a single cluster for 100 workloads, consider using the appropriate cluster design according to VMware Validated Design for Software-Defined Data Center.
