This post will be a brief intro into VMWare’s distributed switch technology and how to get your feet wet in the setup. This will not cover the advanced features or in-depth configuration but a followup may come in the future.
I was myself rather confused at the concept at first and failed to see the use in a lab setting, however, since taking the plunge I can honestly say I am unsure how I survived before and I only hope this post helps those of you new to the concept to give it a go.
What Are Distributed Switches?
Distributed switches, which will be referred to in this post as vDS, is a feature of VMWare vCenter Enterprise Plus allowing centralised provisioning and management of host networking spanning multiple VMWare hosts and clusters. vDS allow for one config change to be made to your virtual networking environment and have this change propagate across the participating hosts, alleviating the need to manually create networks on different hosts.
Following this, vDS allows for consistency in network connectivity when migrating VMs across hosts.
