I have an ESXi 5.5 host with the older S1200BTL motherboard and a v1 Xeon E3. The integrated NIC that ESXi has drivers for is the 82574L but I have a couple i350-T2 cards installed in slots.
I just had a look in the vSphere Web Client and it is showing SR-IOV Status as being Disabled for each i350 based vmnic where the 82574L is showing as “Not supported” so it looks optimistic.
It allowed me to enable SR-IOV but I didn’t click OK to confirm the change as it wasn’t a good time for me to reboot the host.
Thank you Howard, very optimistic indeed! One would think that if it works on the older series, it should definitely work on thisone.
I would tend to agree unless someone wiser than us says to the contrary.
I just checked a similarly configured ESXi 5.1 host with an I350-T4 and it is showing as not supported but it is currently running igb driver version 18.104.22.168 whereas the 5.5 host is running 22.214.171.124 so likely just a driver issue.
I'll try to get the driver on the 5.1 host upgraded over the next few days and see if the status changes to disabled.
I am now curious to try out SR-IOV myself so will test it this weekend and post back.
Looking forward to read about your findings, greatly appreciated.
