Parallel NFS (pNFS) in Technology Preview
Transfer rates faster than NFS support
*) pNFS is an extension of NFS that provides significantly larger data
   transfer rates compared to the traditional NFS architectures. This
   is achieved by processing the meta-data (a typical bottle neck for
   I/O throughput) separately from the actual data. By separating
   the meta-data and the data paths, pNFS allows clients to access
   storage devices directly and in parallel. pNFS is a part of standard
   NFS version 4.1 specification.
*) Support for pNFS is limited to client-side functionality for file
   layout only.
