Hi Guys
I've recently dropped a Mellanox MCX311A 10Gbe card into each of my HP Microserver Gen10's, connected via DAC cables to a Unifi US-16-XG switch. This is the main NIC for vSwitch0, and I've got multiple port groups and vmnics assigned to it. For example
- VLAN-10 NFS
- VLAN-12 VMOTION
But my problem is, a portgroup/vmnic seems to lose connectivity once it carries any significant amount of traffic, for example, I can mount an NFS datastore from my NAS, start a VM, then after a couple of minutes the portgroup/vmnic carrying the NFS loses connectivity, it can't be pinged etc. Yet the other port groups (on the same physical NIC) remain up and connected. If I've move the NFS vmnic to another portgroup, the same thing happens.
My next steps are to update the firmware on the card, and upgrade ESXi to 6.7u2..
But I'm wondering if anybody else has seen or? or any suggestions on how to troubleshoot this?
