Navy Training Commander sees benefits of desktop virtualization at the Naval AviationTechnical Training Unit. The virtual desktop initiative (VDI) is a five year plan to deploy the VDI to more than 36,000 daily users and will replace 80 percent of the more than 23,000 desktop computers in more than 2,500 classrooms at 68 learning sites around the world. Desktop virtualization provides multiple student and instructor workstations from a centralized server environment, which eliminates physical workstations residing in an electronic classroom.
