I wonder if your IMAP issue might have emerged just because suddenly there was the opportunity with all flash. QOS is good on 9.x ONTAP. If anyone says it=E2=80=99s not then they = last looked on 8.x. So I suggest you QOS the IMAP workload. Nobody should be using UDP with NFS unless they have a very specific set of circumstances. TCP was a real step forward. Cheers Richard
