For those who have only heard of the word ‘virtualisation’ and would like to know more this guide contains information on installation, troubleshooting, configuring, virtual storage, and the different virtualisation technologies available to you.

What is virtualisation?
There are numerous definitions of virtualisation, however the basic one is that it is an abstraction of physical resources. This means more than one operating system, with its own set of applications, simultaneously running on just one computer. This is what is commonly referred to as server virtualisation. A different type of virtualisation is storage virtualisation, which means you can have many separate storage devices that can be used as one device when virtualised.
