Lenovo ThinkAgile HX Series appliances can support up to eight network ports; two or four 10 GbE ports (up to
2 NICs), and two or four 10 GbE ports on the LOM adapter, connected to the motherboard. A node requires
network connectivity to function as part of a cluster. If one network interface is available, the failure of the other
network interfaces does not cause service interruption.
A failed NIC is indicated by:
• No LED is illuminated for the network interface
• Guest VM performance degrades
• Guest VMs, the Nutanix web console, and nCLI are unavailable
• VM migration fails with an error message such as:
The migration was cancelled because the amount of changing memory for the VM was
greater than the available network bandwidth
