My question is how to setup a windows 2008 server with multiple nics to generaly best utilize multiple nics? Do I bind services to individual nics? Is there some third party software for windows server that manages general network load balancing? Is there a windows setup procedure that can send traffic to the current least used network interface? NIC Teaming allows you to group between one and 32 physical Ethernet network adapters into one or more software-based virtual network adapters. These virtual network adapters provide fast performance and fault tolerance in the event of a network adapter failure. For those who might not be familiar with Windows Server NIC teaming, it is a mechanism that allows multiple physical NICs to be bound together into a single logical NIC. That logical NIC therefore has the capabilities of all the underlying physical hardware. You can see the end result in the figure below. Jul 09, 2014 I am running Windows Server 2008 R2 on our Dell PowerEdge R720 servers. They have 4 ports per server using Broadcom NetXtreme NICs. I am wondering how I.
The NIC team typically behaves as a single NIC, requiring only a single IP address. Once you configure the team itself, the Windows Server and File Server configuration proceeds as if you had only one NIC. However, NIC teaming is not something included with Windows Server 2008 or Windows Server 2008 R2.

In this topic, we give you an overview of Network Interface Card (NIC) Teaming in Windows Server 2016. NIC Teaming allows you to group between one and 32 physical Ethernet network adapters into one or more software-based virtual network adapters. These virtual network adapters provide fast performance and fault tolerance in the event of a network adapter failure.
Important
You must install NIC Team member network adapters in the same physical host computer.
Tip
A NIC team that contains only one network adapter cannot provide load balancing and failover. 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).
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 [tNICs] or team interfaces) to the operating system.
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. The following illustration depicts a NIC Team with multiple tNICs.
Also, you can connect your teamed NICs to the same switch or different switches. If you connect NICs to different switches, both switches must be on the same subnet.
Availability
NIC Teaming is available in all versions of Windows Server 2016. You can use a variety of tools to manage NIC Teaming from computers running a client operating system, such as:• Windows PowerShell cmdlets• Remote Desktop• Remote Server Administration Tools
Supported and Unsupported NICs
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 not place the following NICs in a NIC team:
Compatibility
NIC teaming is compatible with all networking technologies in Windows Server 2016 with the following exceptions.
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.
Virtual Machine Queues (VMQs)
VMQs is a NIC feature that allocates a queue for each VM. Anytime you have Hyper-V enabled; you must also enable VMQ. In Windows Server 2016, VMQs use NIC Switch vPorts with a single queue assigned to the vPort to provide the same functionality.
Frontpage replacement for windows 10. 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).
Here's why:
Hyper-V Network Virtualization (HNV)
NIC Teaming is fully compatible with Hyper-V Network Virtualization (HNV). The HNV management system provides information to the NIC Teaming driver that allows NIC Teaming to distribute the load in a way that optimizes HNV traffic.
Live Migration
NIC Teaming in VMs does not affect Live Migration. The same rules exist for Live Migration whether or not configuring NIC Teaming in the VM.
Virtual Local Area Networks (VLANs)
When you use NIC Teaming, creating multiple team interfaces allows a host to connect to different VLANs at the same time.Configure your environment using the following guidelines:
Use VLANs with NIC Teaming in a VM
When a team connects to a Hyper-V Virtual Switch, all VLAN segregation must be done in the Hyper-V Virtual Switch rather than in NIC Teaming.
Plan to use VLANs in a VM configured with a NIC Team using the following guidelines:
Manage network interfaces and VLANs
If you must have more than one VLAN exposed into a guest operating system, consider renaming the Ethernet interfaces to clarify VLAN assigned to the interface. For example, if you associate Ethernet interface with VLAN 12 and the Ethernet 2 interface with VLAN 48, rename the interface Ethernet to EthernetVLAN12 and the other to EthernetVLAN48.
Rename interfaces by using the Windows PowerShell command Rename-NetAdapter or by performing the following procedure:
Virtual Machines (VMs)
If you want to use NIC Teaming in a VM, you must connect the virtual network adapters in the VM to external Hyper-V Virtual Switches only. Doing this allows the VM to sustain network connectivity even in the circumstance when one of the physical network adapters connected to one virtual switch fails or gets disconnected. Virtual network adapters connected to internal or private Hyper-V Virtual Switches are not able to connect to the switch when they are in a team, and networking fails for the VM.
NIC Teaming in Windows Server 2016 supports teams with two members in VMs. You can create larger teams, but there is no support for larger teams. Every team member must connect to a different external Hyper-V Virtual Switch, and the VM's networking interfaces must be configured to allow teaming.
If you are configuring a NIC Team in a VM, you must select a Teaming mode of Switch Independent and a Load balancing mode of Address Hash.
SR-IOV-Capable Network Adapters
A NIC team in or under the Hyper-V host cannot protect SR-IOV traffic because it doesn't go through the Hyper-V Switch. With the VM NIC Teaming option, you can configure two external Hyper-V Virtual Switches, each connected to its own SR-IOV-capable NIC.
Each VM can have a virtual function (VF) from one or both SR-IOV NICs and, in the event of a NIC disconnect, failover from the primary VF to the backup adapter (VF). Alternately, the VM may have a VF from one NIC and a non-VF vmNIC connected to another virtual switch. If the NIC associated with the VF gets disconnected, the traffic can failover to the other switch without loss of connectivity.
Because failover between NICs in a VM might result in traffic sent with the MAC address of the other vmNIC, each Hyper-V Virtual Switch port associated with a VM using NIC Teaming must be set to allow teaming.

Network configuration requirements
Before you can create a new NIC Team, you must deploy a Hyper-V host with two network adapters that connect to different physical switches. You must also configure the network adapters with IP addresses that are from the same IP address range.
The physical switch, Hyper-V Virtual Switch, local area network (LAN), and NIC Teaming requirements for creating a NIC Team in a VM are:
Step 1. Configure the physical and virtual network
In this procedure, you create two external Hyper-V Virtual Switches, connect a VM to the switches, and then configure the VM connections to the switches.
Prerequisites
You must have membership in Administrators, or equivalent.
