Cisco had officially launched the Palo adapter for their UCS platform. Now you will have more choice to select the adapter to be used by the UCS platform. While I am searching more information on the net to compare about the different within Palo and Menlo, I found this great article which provide a very detail overview of the UCS networking, nexus 1000v and etc.

Menlo adapter use the general CNA (Converge Network adapter) technology to provide FCoE connection from servers to switch level. Palo is working slightly different which support up to 128 vnic which user will able to present multiple virtual NIC to the UCS system and allow them to implement the VMware environment with multi-gigabits or interfaces VMware environment.  This will be similar to what Xsigo had done on their I/O virtualization solution which allow users to create multiple virtual NIC and virtual HBA to the dedicated physical server. While Cisco are using FCoE and SFP+ connection, Xsigo are base on HCA and infiniband technology.

I will recommend you to take a full view about the article here.
