The importance of IeeePriorityTag with converged RDMA Switch Embedded Teaming

If you read my blog on Switch Embedded Teaming with RDMA (for SMB Direct) you’ll notice that I set the -IeeePriorityTag to “On” on the vNICs that use DCB for QoS. This requires some explanation. When you configure a Switch Embedded Teaming (SET) vSwitch and define one or more management OS vNICs on which you enable RDMA you will see that the SMB Direct traffic gets it priority tag set correctly. This always happens no matter what you set the -IeeePriorityTag option to. On or Off, it doesn’t make a difference. It works out of the box.

Forcing the affinity of a virtual NIC to a physical NIC with a SET vSwitch via Set-VMNetworkAdapterTeamMapping

Window Server 2016 Hyper-V brought us Switch Embedded teaming (SET). That’s the way forward when it comes to converged networking and Software-Defined Networking with the network controller and network virtualization.  It also allows for the use of RDMA on a management OS virtual NIC (vNIC). One of the capabilities within SET is affinitizing a vNIC to a particular team member, that is a physical NIC (pNIC). This isn’t a hard requirement for SET to work properly but it helps in certain scenarios. With a vNIC we mean either a management OS vNIC or a virtual machine vNIC actually, affinitizing can be done for both. The main use case and focus here and in real life is in the management OS vNICs we use for SMB Direct traffic.

Musings on Windows Server Converged Networking & Storage

Why you should learn about SMB Direct, RDMA & lossless Ethernet for both networking & storage solutions

Server, Hypervisor, Storage

Too many people still perceive Windows Server as “just” an operating system (OS). It’s so much more. It’s an OS, a hypervisor, a storage platform with a highly capable networking stack. Both virtualization and cloud computing are driving the convergence of all the above these roles forward fast, with intent and purpose. We’ll position the technologies & designs that convergence requires and look at the implications of these for a better overall understanding of this trend.
