I wondered if there was a way to see what devices are writing the most to the netapp at a given time.  In real time?  Retrospectiely with Netflow or similar?

Google iscsi packet sniffer and you can find many products that can see what MAC addresses are reading/writing as well as the contents if it is that important to you.

Do you have a dedicated segment for the iscsi access?
Do you have managed switche for the iscsi segment??
snmp polling the switch ports could give you info on data in versus data out.

iscsi targets can only be accessed/written to by one host at any one time.
not sure what it is you are trying to get to.
