    Parallel NFS (pNFS) Small Computer System Interface (SCSI) Layout

Abstract

   The Parallel Network File System (pNFS) allows a separation between    the metadata (onto a metadata server) and data (onto a storage    device) for a file.  The Small Computer System Interface (SCSI)    layout type is defined in this document as an extension to pNFS to    allow the use of SCSI-based block storage devices.
