Paper: Standardizing Storage Clusters (with pNFS)
pNFS (parallel NFS) is the next generation of NFS and its main claim to fame is that it's clustered, which "enables clients to directly access file data spread over multiple storage servers in parallel. As a result, each client can leverage the full aggregate bandwidth of a clustered storage service at the granularity of an individual file." About pNFS StorageMojo says: pNFS is going to commoditize parallel data access. In 5 years we won’t know how we got along without it. Something to watch.
