Answer

No, ALL writes are considered synchronous in ONTAP. 

Additional Information

  • Typically clients perform much smaller write offsets when using 'sync' mount option.
  • This causes noticable performance issues as clients will wait for small offsets to be ack'ed before sending the next offset.
