Sun VDI 3.1 is the latest version of Sun's desktop virtualization software. It uses virtualization technologies like VirtualBox and Hyper-V and can host desktops on Sun servers for maximum performance and density. Sun VDI provides centralized management of virtual desktops, session management, and thin client access using Sun Ray devices or RDP. A demo of Sun VDI showed its use at JavaOne 2009 to provide cloned desktops to thousands of users. The future of Sun VDI will be determined following Oracle's acquisition of Sun.
