Hyper-V Networking 101. Part 1: NICs and Switches

There are lots of posts regarding Hyper-V networking. But there doesn’t seem to be a single compiled and up to date guide covering fundamentals and some advanced topics alike. This article aims to fill that gap, without a wall of text but a few easy to understand diagrams, tables, and PowerShell snippets. We will take a look at Hyper-V’s basic networking concept, NIC teaming (Network Interface Card) and different approaches to let VMs (Virtual Machines) talk to specific VLANs or even VLAN trunks.
The first article in the Hyper-V Networking 101 series will cover everything you need to know about virtual switches and NICs. The last post is planned as a real-world example: A way to implement a secure Wi-Fi (and/or wired) guest network on top of a virtual firewall.
Hyper-Converged Needs to Get Beyond the Hype

It used to be that, when you bought a server with a NIC card and some internal or direct attached storage, it was simply called a server. If it had some tiered storage – different media with different performance characteristics and different capacities – and some intelligence for moving data across “tiers,” we called it an “enterprise server”. If the server and storage kit were clustered, we called it a high availability enterprise server. Over the past year, though, we have gone through a collective terminology refresh.
Today, you cobble together a server with some software-defined storage software, a hypervisor, and some internal or external flash and/or disk and the result is called “hyper-converged infrastructure.” Given the lack of consistency in what people mean when they say “hyper-converged,” we may be talking about any collection of gear and software that a vendor has “pre-integrated” before marking up the kit and selling it for a huge profit. Having recently requested information from so-called hyper-converged infrastructure vendors, I was amazed at some of the inquiries I received from would-be participants.
