Today's Scenario

A DR site needs to be setup as our current DC keeps getting snowed in.

Our pointy haired manager has bought us a Vblock in a hosted DC and now we need to set it up.

We have drawn a quick outline of the things we need to do and automate the process so if things go wrong in live we can minimise the amount of downtime to our production systems.

Our Mission is to build a virtual environment in an hour - and show you !
