Eventually, it all comes back to the network. Having servers running VMware ESX/ESXi with virtual machines stored on a highly redundant Fibre Channel SAN is great, but they are ultimately useless if the virtual machines cannot communicate across the network. What good is the ability to run 10 production systems on a single host at less cost if those production systems aren't available? Clearly, virtual networking within ESX/ESXi is a key area for every VMware administrator to understand fully.
In this chapter, you will learn to:
Identify the components of virtual networking
Create virtual switches (vSwitches) and distributed virtual switches (dvSwitches)
Install and perform basic configuration ...
