Storage policy for VM is mapped to datastores in the vSphere environment and used to determine the placement of Tanzu Kubernetes Grid objects like control plane nodes, pod ephemeral disks, container images, persistent storage volumes, and nodes.

VMware vSAN creates the vSAN Default Storage Policy. The default policy can be used, or a new storage policy can be created.

    3. From the drop-down menu, select the vSAN default storage policy.
    4. Select Home > Storage > <datastore_name> and validate that the datastore has the storage policy assigned.
  2. Configure your storage policy with VMFS or NFS datastore.
    1. Log in to the vSphere Client with admin privileges.
