  • 1.  Fault Tolerance with Multiple NICs

    Posted Mar 05, 2014 11:48 PM

    Apologize if this has been asked before.

    I am setting up a vSphere 5.5 environment and I have enough 1GB NICs per host to dedicate two NICs per host for Fault Tolerance.  I was wondering the best way to set this up for maximum network throughput.  Do I set it up like Multi-NIC Vmotion?  Like stated here: VMware KB: Multiple-NIC vMotion in vSphere 5. Basically using two Port Groups like FT-1 and FT-2.  Or do I have to do it like Multi-NIC iSCSI with separate vswitches and each vswitch with a one of the Port Groups.

    Thanks in advance.

    Are you running into a throughput issue when using 1 nic for FT?

    Currently FT only supports using a single nic (1G or 10G)

    No throughput issue, just initial setup and redundancy is needed.  Thanks for your answer though as this tells me I have to use a single port group (maybe even just a single switch) with one adapter as active and the other standby.

    Appreciate the help!
