The three-pod design core platform consists of the same components that are used in the two-pod design with some differences in the way these components are combined to build the solution. This section of the document focuses on the main differences between the two-pod and three-pod design.
Three-Pod vCenter Server Design The three-pod vCenter Server design separates the management, edge, and resource functions into their own dedicated pods. The three-pod vCenter Server differs in that the second vCenter Server instance manages separate clusters for the resource and edge functions.
Three-Pod Virtual Networking Design with NSX Manager The second NSX Manager in the Management pod is associated with the vCenter Server instance that manages the Edge pod. CSP network administrators use this instance of NSX Manager to operate tenant network services. Tenants must coordinate their connectivity needs with the administrator during VNF onboarding.
Three-Pod vCloud Director Design vCloud Director is configured with access to only the resource clusters in the Resource pod for the deployment of telecommunications workloads. CSPs retain full administrative control of the Edge pod and leverage the two management components, vCenter Server and NSX Manager, for its administration. Further details about edge services and their consumption by tenants are described in the Secure Multitenancy section of this document.
