Answer

  • NFS Plug-in  is not meant for cold storage migration process
  • Purpose is to offload some tasks to the storage array to completely eliminate I/O
  • No tweaking of I/O consumption
  • Example: To copy a file, an RPC call is used
    • How the plug-in works is:
      1. The Plugin sends RPC call to ONTAP. Tells “ONTAP” to “copy this file”
      2.  ONTAP will copy it within the storage array
      3. Once a copy is complete, ONTAP sends a RPC call back to say “Its done”
