Hey Sean - Clustered Ontap 8.3.2P5 Model AFF 8060, VSC setting have been applied. Yes VSC settings have been applied and hosts rebooted.
Switches are 5k's VPC port channel for NFS ifgrp on the AFF's. 1 port from each netapp port channel to 5k switch 1 and 2 - MTU 9000 throughout.
I have read that article but that article seems to of been written if you are experiencing random APD's through a normal day.
I have a support ticket open with VMware - who have suggested the drop in MaxQueueDepth to 32 based on what the storage vendor says.
I also have a ticket with Netapp which has not gotten very far
