This Internet-Draft provides a description of the pNFS extension for NFSv4.
The key feature of the protocol extension is the ability for clients to
perform read and write operations that go directly from the client to
individual storage system elements without funneling all such accesses
through a single file server. Of course, the file server must coordinate
the client I/O so that the file system retains its integrity. The extension
adds operations that query and manage layout information that allows
parallel I/O between clients and storage system elements. The layouts are
managed in a similar way as delegations in that they have leases and can be
recalled by the server, but layout information is independent of
delegations.
