Seb Hakiel of vWired.co.uk gives a quick tip on the Nutanix network resiliency:
This seems to be resilient, however I discovered (whilst reading documentation, not through hardware failure) that the 2 x 10GigE ports actually reside on the same physical card, so this could be considered a single point of failure. To work around this single point of failure, I would suggest incorporating the 2 x 1GigE network ports into your vSwitch and leave them in Standby.
