- [Instructor] In this video we'll learn about Network IO Control and how it uses shares, limits, and reservations, to control access to physical bandwidth. Network IO Control requires the vSphere Distributed Switch, so you can see here, we've got a vSphere Distributed Switch configured and running. And so I have to have that in order to enable Network IO Control. And the vSphere Distributed Switch comes with the enterprise plus licensing edition of vSphere. So Network IO Control allows us to ensure that certain types of traffic are granted sufficient bandwidth. So for example, in our diagram here, VM Traffic is granted 100 shares, that's twice as much as iSCSI or vMotion. So VM Traffic is basically going to get double the bandwidth. But, its only going to get double the bandwidth, if there's contention, shares are only enforced when contention occurs. So during periods where bandwidth is scarce, Virtual Machine Traffic…
