Starting with Database Version 11g, Oracle offers with Direct NFS an integrated NFS-Client, which is independent from the underlying OS-based NFS-Client. This allows direct access to the NFS storage for the Oracle Instance and realizes Oracle’s own optimizations. In addition, one can implement multipathing over four parallel ports, independently from any switches, NIC bonding or teaming. The Oracle Instance configures the communication with the NFS automatically and thus facilitates the configuration under RAC. Using Oracle Direct NFS, shortly dNFS, also provides using NFS Storage with Oracle Instances on Windows systems.
