When you think of the beginning of Server Virtualization, companies like VMWare may come to mind. The thing you may not realize is Server Virtualization actually started back in the early 1960’s and was pioneered by companies like General Electric (GE), Bell Labs, and International Business Machines (IBM).
Disaster recovery can be a difficult thing to plan for. You back up your systems; perhaps you replicate your data to an off-site facility; maybe you even build all redundant systems.
After doing all of these things, what is your goal? It is to get your systems back up and running after some sort of a disaster, such as your building burning down; or an electrical failure in your data center.
Below I have listed a few possible scenarios you may encounter. In these scenarios I outline a few problems you may encounter, but from a Server Prospective. The network recovery is for another article.
In this video I explain where to get Citrix Xenserver and how to install it. I use a Virtualbox Virtual Machine in my demonstration, however you would not want to run Xenserver in a Virtual Machine in your production environment. I can't really think of a situation where you would want to do that.
I hope you enjoy the video, and be sure to send me any questions you have either by commenting on this article, or sending me a message via the Contact Us section at the top of the page.
When selecting you hardware, there are many factors to consider; How many Virtual Machines do you want to run at a time? How busy will these Virtual Machines be? If you are getting ready to P2V a bunch of virtual machines, then you should use Perfmon (In a Windows Environment) to take a benchmark before proceeding.
