3.1.2 Large Data Center Deployment
Large-scale cloud environments primarily use a dedicated vSphere or vCenter Server for the management cluster. vSphere or vCenter Server is typically already deployed before VMware NSX is introduced in the architecture. When that happens, one or more dedicated vCenter Server instances are added to the management cluster to manage the resources of the VMware NSX domain (edge and compute clusters) as shown in the following figure.
Figure 4. Dedicated vSphere or vCenter Server Managing All NSX Components
This design approach has the following advantages:
• Avoids circular dependencies, because the management cluster is outside of the domain it manages
• Provides mobility of management cluster for remote data center operation
• Supports integration with existing vSphere and VMware vCenter® offerings
• Provides ability to deploy more than one VMware NSX domain
• Upgrade of the main vCenter Server does not affect the VMware NSX domains
• Supports use of site recovery and other explicit-state management systems
