Am I wrong, or the only bad thing with this setup is that we can’t do ISCSI Multipath ?
Causse in this setup if I understand correctly each NetApp controller have ISCSI IP in only one vlan …

I would like to thank you for your blog post. We followed your configuration as closely as possible (minus IP addressing and vlan ids). I ended up having the e3a and e3b mixed up as to what was cabled where on the VC side. Since we are stacking two enclosures, we split the connections between the two chassis and created the SUS’s so controller A’s connections were one SUS and controller B’s connections were a second SUS. Since I only have a single port on the blade usable for this traffic, I set LOM2-a to multiple networks and specified both ethernet networks. Then on the vmware side, I created another vSwitch and created vmkernel port groups for both networks. Since we also have a requirement to do CIFS to the VM, I created two virtual machine port groups (one with each vlan). Then on the VM side, I added a nic for each portgroup. Once a static IP address was assigned that was on the same subnet as the Netapp, CIFS came right up.
