I see "one-to-one" configurations used for Management and vMotion networks way too often, where a vMotion network will use one physical uplink, and Management will use the other, that's it--

It's a common configuration, and exists in environments of all sizes. Unfortunately, it represents a single point of a failure, and the potential for a really bad day if the Management network drops and your HA configuration starts shutting down your virtual machines.

And it's so easy to fix!! Check out the video below to see the "problem scenario" and how easy the solution is to implement.
