Storage policies are created for the datastore placement for Kubernetes control plane VMs, containers, and images. Storage policies are associated with different storage classes. Before workload management is enabled, a storage policy is created for the placement of Kubernetes control plane VMs.
For information about storage policy creation with vSphere, see https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere- with-tanzu/GUID-544286A2-A403-4CA5-9C73-8EFF261545E7.html#GUID-544286A2-A403-4CA5-9C73-8EFF261545E7.
