SnapMirror transfers are slow from 7-Mode to cluster mode
Applies to
- ONTAP 9
- Data ONTAP 7-Mode
- SnapMirror
Issue
- Snapmirror transfers are slow (less than 5MB/s) from an old 7-Mode system to new cluster mode
- The new destination cluster mode system is not used for any workload
- The 7-Mode storage system usage is low, especially after-hours when testing replication performance
- Both systems use the on same switches with no routers in between
- 1500 MTU set and nothing wrong is found on the network
