We have a couple A5800 Switches to support SFP+ 10Gb networking. For the servers we picked up X520-DS2 nics. Hardware wise we get link lights from the switch over to the NICS.
However, the Intel Nic's Drivers are faulting and disabling the card saying 'unsupported SFP Module Detected'.
Talked with Intel about this and they are saying that HP isnt identifying their SFP EEPROMs correctly, so their Driver is dumping the card due to that.
we are demanding a fix from HP on this, as the cables are listed to support these cards, So I expect some inhouse testing was done to prove that?
