When might you use this form of load balancing? A typical scenario might be if the number of virtual machines running on the host is much greater than the number of physical NICs in the team on the host. Just be sure that the physical NICs can provide sufficient bandwidth to the workloads running in the virtual machines. This discussion only scratches the surface, however, because there are other scenarios you might encounter when considering NIC teaming as a possible solution. For example, if you implement Windows NIC Teaming on a Hyper-V host and your virtual machines need to be able to utilize bandwidth from more than one NIC in the team, then an option for you (if your Ethernet switch supports it) is to configure LACP or Static Teaming as your teaming mode and Address Hash as your load-balancing mode. This is possible because it’s how you configure the Ethernet switch that determines how traffic will be distributed across the team members. This scenario is kind of unusual, however, because typically if you have a virtualized workload that requires high bandwidth for both inbound and outbound traffic (such as a huge SQL Server database workload) then you’re probably only going to have one or two virtual machines running on the Hyper-V host. Finally, when should you use the new dynamic load-balancing mode? Unfortunately, we can’t provide guidance concerning this at the time of writing because the documentation on Windows NIC Teaming hasn’t yet been updated. So your best bet for more detailed guidance on implementing NIC teaming in different configurations is to keep a watch on the link to this topic in the “Learn more” section at the end of this chapter.

Improved network diagnostics CHAPTER 5 97 Windows Server 2012 R2 includes new features in Windows PowerShell that can help you troubleshoot network connection problems when they occur. But before we examine some of these improvements, let’s start by briefly reviewing some of the network diagnostic capabilities of Windows PowerShell in the previous version Windows Server 2012. Network diagnostic cmdlets in Windows Server 2012 If you’re experiencing what might be a networking issue with one of your servers, the first thing you probably want to check is the configuration of the network adapters. The Get-NetAdapter cmdlet was first introduced in Windows Server 2012 as a way of retrieving the configuration of all physical network adapters in the server. For example, let’s see what happens when we run this command on a Hyper-V host named HOST30.contosol.com that is running Windows Server 2012 R2: PS C:\> Get-NetAdapter Name InterfaceDescription ifIndex Statu s ---- -------------------- ------- ----- vEthernet (Broadcom Ne...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
