The technique of merging the existing resources in a system by dividing up the obtainable bandwidth into paths, each of which is independent of one another, and each of which may be added (or removed) to a specific server or machine in real time is called Network virtualization. Each path is separately secured. Every user has joint access to the resources on the system from a particular computer.
Management of network can be a monotonous and lengthy affair for a human manager. Network virtualization is designed to enhance productivity, competence, and work satisfaction of the manager by carrying out lots of these tasks mechanically, thereby masking the actual intricacy of the system. Images, files, folders, and programs can be centrally handled from a particular physical location.
Storage media like tape drives and hard drives can be simply added or removed. Storage area can be pooled or distributed between the servers.
