IHAC that is planning to implement Fabric MetroCluster using a DWDM topology.
DWDM is already in place and it is used by EMC VPLEX.
I have read TR-3548 for Fabric MetroCLuster ISL considerations and I talked to customer in order to understand DWDM infrastructure:
- they have unused ports for attach FC ISL for NetApp on both sides
- they can use a different lambda for NetApp
AFAIK it seems a valid requirement, but I would like to confirm it.

Unfortunately I can't see the image in your post - so I may not understand your question fully.
As you have seen in TR-3548, we do support DWDM, as long as the device used for DWDM is compatible with the Cisco or Brocade switch used in the metrocluster.
Does this answer your question?
