Snapmirror Fan-Out

Answer

  • SnapMirror operates as a background process within ONTAP and has a lower priority than client access, so the fan-out configuration typically does not impose a high load on the system.
  • However, if the system is under high load, SnapMirror transfer processes may be affected.
  • In fan-out configurations with multiple SnapMirror destinations, throughput is distributed among the destinations, which may result in lower individual transfer speeds.
  • These impacts depend on system configuration, network bandwidth, and storage load.
