active NIC versus fail over NIC

I just recently deployed a VSA two node cluster.  I have 2 x NICs on all virtual switches on all ESXi servers..  By default most of them where set for both NICs to be active.  I changed it to one being active and one being for standby.  My goal is to only use the standby NIC for failure / fail over only.  Is this configuration correct?

In my experience, you should have both NICs working as a single NIC that's run by a hardware or software controller.  You'll get the throughput and failure redundancy of both.

Yes; if the 'active' vmnic goes down, the 'standby' one will be used.

You may also need to change the teaming policy, and check your physical switch configuration is cprrect.

Make sure you test, test, and test again this configuration.
