Global Name Space solutions like those available from Acopia or built into OnStor NAS products are ideal for solving the complexity of managing multiple drive letters or teaching users different paths to servers. A Global Namespace can deliver a single mount point for the users to access all their data, despite the fact different folders that make up that data are on different NAS heads throughout the enterprise. You don’t have to know the exact path to a file, the meta data is captured and the mounts and pathing are done transparently in the background.”]
