Prism Central has Image management feature that allows pushing disk images to managed Prism Element instances based on configured image placement policies. The policies rely on categories that are associated with both images and clusters. Altogether this allows building a granular and intricate (if you chose to) set of image distribution policies.
If for any reason using Image Management is not an option for you, you can push images from the PC to the clusters of choice manually either using PC CLI.
