Jumbo Frames and Converged Fabric in Server/Hyper-V 2012

I’ve added a new post on the Altaro site. Its original purpose was to illustrate how to get virtual adapters on a virtual switch to support jumbo frames, but along the way I also demonstrate how to build a converged fabric to use for the server roles as well.

I’ll do my best to keep this posting on an even keel and not let it devolve into a rant, but no promises. As I poke around in various technical forums, whether LinkedIn or Spiceworks or TechNet or whatever, a new theme is popping up. People are complaining that they’ve dropped in a shiny new 10G network and just can’t figure out why it’s not any faster than their old 1GB network, or they’re using internal/private networks inside Hyper-V or ESX and they don’t go any faster than a standard copper line. In a couple of cases, I’ve actually taken the effort to try to explain what’s going on, but usually it falls on deaf ears.
