Sign in to vote. For SR-IOV, data is delivered directly to the NIC without passing it through the networking stack in the host operating system, in the case of virtualization. Therefore, it is not possible for the NIC team to inspect or redirect the data to another path in the team.

Native host Quality of Service QoS. When you set QoS policies on a native or host system, and those policies invoke minimum bandwidth limitations, the overall throughput for a NIC team is less than it would be without the bandwidth policies in place.

TCP Chimney. You should not use Depending on the switch configuration mode and the load distribution algorithm, NIC teaming presents either the smallest number of available and supported queues by any adapter in the team Min-Queues mode or the total number of queues available across all team members Sum-of-Queues mode.

If the team is in Switch-Independent teaming mode and you set the load distribution to Hyper-V Port mode or Dynamic mode, the number of queues reported is the sum of all the queues available from the team members Sum-of-Queues mode. Otherwise, the number of queues reported is the smallest number of queues supported by any member of the team Min-Queues mode. When the switch-independent team is in Hyper-V Port mode or Dynamic mode the inbound traffic for a Hyper-V switch port VM always arrives on the same team member.

When the team is in any switch dependent mode static teaming or LACP teaming , the switch that the team is connected to controls the inbound traffic distribution. The host's NIC Teaming software can't predict which team member gets the inbound traffic for a VM and it may be that the switch distributes the traffic for a VM across all team members.

When the team is in switch-independent mode and uses address hash load balancing, the inbound traffic always comes in on one NIC the primary team member - all of it on just one team member. Since other team members aren't dealing with inbound traffic, they get programmed with the same queues as the primary member so that if the primary member fails, any other team member can be used to pick up the inbound traffic, and the queues are already in place.

Following are a few VMQ settings that provide better system performance.
