Networked File System Switching / Routing & Secure Net-NFS
Source: Calsoft Labs
Network file systems have been around over decades. But so far there has not been any real NFS experience that is truly scalable, secure, fault tolerant and highly available, without using costly hardware solutions/purpose built operating systems. No real innovation happened in the area as it relates to the networking side of the NFS file data packets. The advantage of Net-NFS comes mainly from the network level processing/routing of the NFS RPC, as opposed to server level processing. The architecture decouples physical NFS servers from the clients, as they talk to a single, Virtual NFS server that presents a NFS server interface to NFS client access.
