SDDC-VI-VC-012

Create a single management cluster containing all management hosts.

Simplifies configuration by isolating management workloads from compute workloads.

Ensures that compute workloads have no impact on the management stack.

You can add ESXi hosts to the cluster as needed.

Management of multiple clusters and vCenter Server instances increases operational overhead.

SDDC-VI-VC-013

Create a shared edge and compute cluster that hosts compute workloads, NSX Controllers and associated NSX Edge gateway devices used for compute workloads.

Simplifies configuration and minimizes the number of hosts required for initial deployment.

Ensures that the management stack has no impact on compute workloads.

You can add ESXi hosts to the cluster as needed.

Management of multiple clusters and vCenter Server instances increases operational overhead.

Due to the shared nature of the cluster, when compute workloads are added, the cluster must be scaled out to keep high level of network performance.

Due to the shared nature of the cluster, resource pools are required to ensure edge components receive all required resources.
