My suggestion for EVA-Switch connections would be to put all odd FPs on one fabric and all the evens on the other. FP1 & FP3 to switch1 and FP2 & FP4 to switch2. I don't have any diagrams to share with you, I must admit.
The Array LUN groups should have separate paths to the V-Series via separate fabrics. For two host ports per controller, following the EVA traditional practices and connecting FP1 of both controllers to switch1 and FP2 to switch2, then the array LUN group would not have EVA controller redundancy..
From an EVA standpoint, the (traditional) odd and even connections also look to spread their connections across the switches..I am no EVA expert, but I am wondering if below works (and supported). This *may* meet both the NetApp and EVA requirements.
We are font-ending an EMC SAN with a VSeries but same idea I would guess with your EVA. Here's a picture of what our cabling looks like. Fairly standard I would think if you need to be redundant at all levels of the fiber fabric.
