Hello,
We have just purchased 8 Intel® Ethernet Converged Network Adapter X710-DA4 and we have installed them in our Dell R610 VMware 5.5 hosts. The cards at first seem to work well and preform well however we now have an issue where the links on all of our hots flap. The nic resets one port at random time intervals and then comes right back into service. We see the same behavior on all of our ESXi Hosts. These cards are being connected to a Cisco Nexus 5700 switch using Twinax Copper Cables. We talked to VMware and they seem to think its a firmware issue or something on the card. Both Dell and Cisco have looked at the server and network hardware and do not see any issues. Does anyone have any suggestions?
Thanks
Intel x710
