#WHAT IS NIC TEAMING IN VMWARE 6.0 WINDOWS#
In Windows Server 2016, VMQs use NIC Switch vPorts with a single queue assigned to the vPort to provide the same functionality.ĭepending 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). Anytime you have Hyper-V enabled you must also enable VMQ. VMQs is a NIC feature that allocates a queue for each VM. To learn about using NIC Teaming within virtual machines (VMs) that run on a Hyper-V host, see Create a new NIC Team on a host computer or VM. You should not use 802.1X Authentication with NIC Teaming because some switches do not permit the configuration of both 802.1X Authentication and NIC Teaming on the same port. TCP Chimney is not supported with NIC teaming because TCP Chimney offloads the entire networking stack directly to the NIC.Ĩ02.1X Authentication. 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. Therefore, it is not possible for the NIC team to inspect or redirect the data to another path in the team. 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). NIC teaming is compatible with all networking technologies in Windows Server 2016 with the following exceptions. NICs that use technologies other than Ethernet, such as WWAN, WLAN/Wi-Fi, Bluetooth, and Infiniband, including Internet Protocol over Infiniband (IPoIB) NICs. Attempts to team vNICs might cause a complete loss of communication if network failures occur. Teaming of vNICs inside of the host partition is not supported in any configuration. Hyper-V virtual network adapters that are Hyper-V Virtual Switch ports exposed as NICs in the host partition.ĭo not place Hyper-V virtual NICs exposed in the host partition (vNICs) in a team. You can not place the following NICs in a NIC team: You can use any Ethernet NIC that has passed the Windows Hardware Qualification and Logo test (WHQL tests) in a NIC Team in Windows Server 2016. You can use a variety of tools to manage NIC Teaming from computers running a client operating system, such as: NIC Teaming is available in all versions of Windows Server 2016. If you connect NICs to different switches, both switches must be on the same subnet. The following illustration depicts a NIC Team with multiple tNICs.Īlso, you can connect your teamed NICs to the same switch or different switches. Since Windows Server 2016 supports up to 32 team interfaces per team, there are a variety of algorithms that distribute outbound traffic (load) between the NICs. When you configure network adapters into a NIC team, they connect into the NIC teaming solution common core, which then presents one or more virtual adapters (also called team NICs or team interfaces) to the operating system. However, with one network adapter, you can use NIC Teaming for separation of network traffic when you are also using virtual Local Area Networks (VLANs). A NIC team that contains only one network adapter cannot provide load balancing and failover.
