Hello,
in the last ESXi installation (6.0, 6.5 update 1 and update 2 and 6.7 too) we've found strange problem with this configuration:
HARDWARE
Fujitsu Primergy TX2550M4 with 2 on board Intel X722 1GbE2 NIC seen from vSphere with i40en driver.
VSS CONFIGURATION
1 vSwitch with 1 MGMT kernel port group and 1 VM PG
Both vSwitch and PG (all) has 2 nic in teaming active / active configuration
VSPHERE SOFTWARE VERSION (all with problem)
On vSphere 6.5 update 2 I've already tryed to upgrade the driver with i40en-1.7.17-1OEM.650.0.0.4598673.x86_64.vib.
Then I've tryed to upgrade the host to 6.7 update 1, still got the problem.
Then updated the 6.7 update 1 and still go the problem (witch i40en 6.5 driver)
Then updated via esxcli command line to VMW-ESX-6.7.0-i40en-1.7.17-11283970
THE PROBLEM
from a pc connected to the network I keep ping on ESXi management IP and VM IP
sometimes I lose near to 10 packets just vs the ESXi, while I don't lose any ping to the VM
IF I change the PG management ESXi teaming from active active to active / passive I don't lose any ping
I've seen a lot of forum about i40en, but anyone the has similar problem.
Any help would be appreciate
Thanks
Luca
