10GbE with 1GbE standby?

ON paper this should work, but I just wanted to see if anyone has done something like this.     We are upgrading the VM hosts to 10GbE, but the adapters we can find from HP only come in 2 port models.  I would prefer two individual cards to protect against a card hardware failure, but these cards aren't cheap and PCIe slots are at a premium in some of the hosts...   So I was thinking, the hosts all have plenty of 1Gb ports, why not run the dual 10GbE links from the one card and then make a 1Gb port as the standby for the rare occurrence of a total NIC failure.  Worst case, that would keep everything running at slower bandwidth while I have a chance to vmotion and fix the problem with no downtime.  Our storage is all on 8Gb FC, so this would not be storage traffic.   

 

Sound good?

 

I'd just add the 1Gb port under "Standby Adapters" and the two 10Gb ports under "Active Adapters" in the NiC teaming tab under the vswitch properties, right?
