Fabric MetroCluster and DWDM clarification

Hi,

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.

Any comments? 

Regards, Rafael.
