This document discusses how Horizon View can be integrated with NetApp storage to improve performance and reduce costs for desktop virtualization. It describes various cloning methods like native linked clones, VCAI linked clones, and full clones. It also discusses technologies like View Composer, cloning refresh processes, and the View Storage Accelerator to optimize storage usage and desktop performance. The document aims to help customers choose the best cloning approach and design their virtual desktop infrastructure efficiently.
