VMware vSphere 6.7 Network I/O Control – getting under the hood

If you are a VMware vSphere administrator who wants to solve the problem of a low network throughput, Network I/O Control (NIOC) is exactly what you need! It’s a traffic-specific vSphere Distributed Switch (vDS) mechanism of network bandwidth regulation that was firstly introduced in vSphere 4.1 in 2010. NIOC appeared when 10G networking was increasingly prevalent and became a real breakthrough. With this mechanism, you can ensure high network throughput and go with fewer network adapters in ESXi hosts. That sounds pretty good, doesn’t it?
