NFS ARCHITECTURE by Mudit Garg

NFS^2 provides a mechanism for uniting NFS servers under a single namespace. It simplifies management of multiple NFS servers by providing access to all servers through a single namespace (no need for multiple client mount points), and by providing a transparent mechanism for the addition of new servers as the system grows. This system avoids distributed lock management, which has been a limiting factor in the scalability of cluster file systems. NFS^2 supports heterogeneous physical file systems within the single namespace, whereas other systems have relied on their ownproprietary physical file systems.
