An administrator is tasked to create a new vSphere Zone for the highlighted namespace.

Configure tab

In the context of VMware Cloud Foundation (VCF) 9.0 and vSphere with Tanzu, a vSphere Zone is a critical infrastructure object used to represent a failure domain. Specifically, it allows the vSphere Supervisor to span across multiple vSphere clusters (typically three) to provide high availability against a complete cluster failure. This " zoned " deployment model ensures that the Supervisor Control Plane and workload cluster nodes (VKS) are distributed across different physical racks or data centers.

To start the process of creating a new vSphere Zone, an administrator must navigate to the Configure tab. While the provided screenshot highlights a specific namespace (other-namespace), the creation of the underlying infrastructure zones is an administrative task performed at the vCenter Server or Cluster level. However, within any object’s view in the vSphere Client, the Configure tab serves as the primary gateway for all lifecycle management and setup tasks. For a vCenter-level configuration, the path is vCenter Server > Configure > vSphere Zones . Once a zone is created and mapped to a vSphere cluster, it can then be associated with a Supervisor. In the namespace-specific view shown, the Configure tab is also where the administrator would verify the placement of the namespace on a zoned Supervisor and manage the association with specific Supervisor Services. By clicking Configure , the administrator accesses the sub-menus required to define and modify these high-level SDDC constructs, bridging the gap between traditional vSphere resource management and the declarative Kubernetes environment provided by VKS.
