5 tips for deciding whether to virtualize a server



1. 1: Take a hardware inventory

If you're thinking about virtualizing one of your physical servers, First you begin by performing a hardware inventory of the server. Find out up front whether the server has any specialized hardware that can't be replicated in the virtual world.




2 2. Take a software inventory

Take a full software inventory of the server before attempting to virtualize it. In a virtualized environment, all the virtual servers run on a host server. This host server has a finite pool of hardware resources that must be shared among all the virtual machines that are running on the server as well as by the host operating system.

3.3. Benchmark the system's performance

4.4. Check the support policy

5.5. Perform a trial virtualization
