Two interesting follow-up points: 1. DCB Protocols: In case of OpenFlow - does one need pt-pt protocol like DCBX to achieve "lossless" priority negotiated in the path or OpenFlow will programmatically achieve same results? 2. FCoE functionality in switches/adapters: What extensions are supported by OpenFlow for this?

At a high-level, OpenFlow is an abstraction over existing hardware, so it's in theory entirely possible to try to expose FCoE or iSCSI functionality through OpenFlow. That said, the current standards do not support it natively, but do provide extension mechanisms that you could consider using.
