Applies to

  • ONTAP 9
  • CommVault

Issue

  • Backup is slow with sufficient controller and network resources
  • No failures seen in the logs
  • Packet trace for the data connection shows that the MediaAgent was sending zero windows to the NetApp NDMP server
  • The receiver’s window size is a mechanism used by TCP to prevent the source from overwhelming the destination
