The current release, do not support FCoE multi hop yet, there for if you have a nexus 5k in place, you can use it as the 10G network uplink for Layer 2 scale out perspective. Future roadmap will support FCoE multi hop, until that ready, you will require to uplink to the SAN switch for Fiber channel access.

That seems rather inefficient, but just curious of the E/TE's are indeed supported like mentioned.

For the FC uplink from UCS 6120 will go to the FC module in Nexus 5k for SAN zoning purpose. FCoE multi hop to 5k directly is not supported in this release, therefore you need to connect the FC to FC directly from UCS 6120 to Nexus 5k on FC module in this case FCoE is within UCS you are correct.

What I am speaking of is: UCS -> 6120 -> 5k -> MDS Where the UCS is doing FCoE, there is NO FC card in the 6120, but instead target resides on MDS and initiator is FCoE on UCS. Only supported configuration is initiator on UCS and target on 6120, multi level FCoE not supported at this release I am told (even though it may work), thoughts?

As for now, I will able to tell you that UCS 6100 is not fully function as Nexus 5000 did. Both product is behave slightly differently which Nexus 5000 is end to end FCoE but UCS 6100 is only up to the level from Chassis to switch and not until the storage level.

Or this is just an example? Wondering why both the Cisco UCS 6100 FI do not cross connect to SAN A and SAN B? Or this is just an example?
