Thank you! Just for my own clarification since this is the first time i am dealing with the MDS product line. I would be able to plug the MDS into the current EMC FC switch and then have the SAN that is attached to the EMC FC switch be able to route to the second SAN across the WAN link? The EMC is 4GB FC but the MDS i believe is 2GB FC, would there be a compatibility issue?

Yes, think of the FCIP connection as just an ISL link abeit that it is over an IP connection. So, you are just creating a multi-switch environment. Again, it's probably not recommended to route over a FC ISL link to get to a MDS doing FCIP but also, its not the end of the world. It depends on how much the FCIP replication traffic is occuring and if you are overloading the FC ISL links. The speeds will autonegotiate to their maximum speeds and you can create portchannels to the EMC switch to consolidate bandwidth. Just turn the loadbalancing to src/dst if that emc switch is not a MDS rather than default src/dst/oxid.

Wonderful, thank you. You've been very helpful.
