Hi @FrancWest . I'm not going to answer your question - instead, I'm going to tell you how I have handled this design decision in the past. As soon as someone tells me they want to run storage over IP I adopt fibre channel principles - of having two fabrics. I create two separate Meraki networks, "A" and "B", and I put a switch into each. Being in separate networks, you pretty much don't need to do anything special as the networks never seem to get automatic upgrades at the same time (it becomes "set and forget"). Make sure the time for scheduled maintenance is different on the two network (in case you cloned "A" into "B"). If you want, you can have all your switches except one in the "A" network, but there must always be a separate standalone switch in the "B" network.
