Anyone has any real life experience of using the Cisco 10GE Twinax cables to connect this to servers with NIC cards that accept SFP+? I'm talking servers like HP and Dell which have 10GE NIC cards. For the switch,  I would be using Nexus 5548UP. The SFP+ part number would be SFP-H10GB-ACU10M.


The SFP-10G-SR is too expensive and I'm looking at 10GE Twinax cables as an alternative but am quite concerned about the compatability.

Yes, the twinax cables are all we ever use to connect servers to Nexus 5ks. We have used them with both Qlogic and Emulex CNAs. If the server is more than 10m from the switch the 10G-SR and 50 micron fiber are required.
