NetApp 3040a Clustered Link Aggregation - vif

I've got (2) NetApp 3040a clustered systems both running LACP Aggregated vifs (nics) for my NFS VMWare Connections. One cluster is running on Cisco Catlyist 3750's and the other is running on a Cisco Catlyist 4507. Both switches are setup redundantly. The fail over / load balance is excellent. Here's how I set it up:

My switches are set to IP Load Balance (global switch setting)

Commands I used to setup the nics on the NetApp. This puts onboard nic c and d and add on card port c and d in an aggregated LACP vif called SANAprivate. I use this for private NFS traffic for my VMWare ESX Hosts. The next command sets the IP Address info and adds the partner vif for cluster failovers / non-disruptive SAN upgrades.
> vif create lacp SANAprivate -b ip e0c e0d e4c e4d

> ifconfig SANAprivate 192.168.217.11 up netmask 255.255.255.0 broadcast 192.168.217.255 -wins mediatype auto trusted partner SANBprivate

> vif status SANAprivate
default: transmit 'IP Load balancing', VIF Type 'multi_mode', fail 'log'
private: 4 links, transmit 'IP Load balancing', VIF Type 'lacp' fail 'default'

Cisco Switch Config
We tested this by pulling Cables from each of the 4 nics up to 3 at a time, so each nic would be by itself and with other nics while pulling data from the link aggregation. We setup multiple connections so we were pulling more than 1 nics worth of bandwidth. I have had very good results with this configuration and have not seen any issues with teaming the onboard nics and the addon nics.
