Hi
I have a question surrounding the native NIC Teaming in Windows Server 2012 R2 with regards to the i350 Quad Port adapters.
In our Hyper-V implementation, we have 3 x quad port NICs per Hyper-V Cluster node.
With two of these adapters, we have balanced a Switch Independent / Dynamic (Sum of Queues mode) team across 4 of these ports for our VM Switch. Here's the thing... two of these ports are on one physical adapter and the other two ports are in the second physical adapter. Each port has VMQ enabled with suitable processor core allocations for a Sum of Queues team. VMQ is required as the team is connected to a VM Switch which is then supporting a reasonable number of Virtual Machines.
The remaining 4 ports in these two adapters (2 in one card and 2 in the other) are then allocated to iSCSI MPIO use for access to our SAN. These remaining ports have RSS enabled.
The questions I have are as follows:
A) What is Intels Stance when mixing RSS and VMQ modes on different ports, on the same physical adapter?
B) Is splitting a VMQ enabled NIC team between ports from physical NICs supported by Intel when using the native Windows NIC Teaming in Server 2012 R2?
We are seeing intermittent latency issues and packet loss from within virtual machines with VMQ enabled. Disabling VMQ does work around the issue, however this isn't really a solution.
Are there any known issues with these adapters when using Virtual Machine Queues?
Kind Regards
Matt
