Can virtualisation rejuvenate your old servers?

It is a commonly held belief that most servers sit around doing very little most of the time. So, according to the theory, it makes sense to take advantage of that otherwise wasted capacity by loading up a hypervisor and running multiple virtual servers on the same hardware.
If only it were that simple. This kind of server consolidation has its advantages, but it is not necessarily the best or most cost-effective approach to going virtual.
Here’s how to decide for or against.
The first port of call has to be an understanding of what you have and how stretched your hardware really is
