Global Namespace

File virtualization technology based on global namespaces (GNSs) is used to solve problems encountered by file management.

What Is a GNS?

A GNS converges file systems scattered on different storage systems to a virtual root directory /, providing a unified logical view and simplifying file access and management. Figure 1-1 shows the typical structure of a GNS. The top of a GNS is a virtual root directory, which is represented by a slash (/).

What Are the Benefits of GNSs?

GNS is the core of file virtualization technology. Similar to Domain Name System (DNS) which enables users to visit websites without memorizing IP addresses, a GNS enables clients to directly access files without knowing their locations. A GNS adopts a unified logical view for file management. Users can create their own file folders or access authorized file folders.
