Now, did I include Vector Analysis in this question?
My issue with this problem is the "it depends" clause. I know that there are
hardware, telecom, power, etc... considerations.
However, if I am trying to pursuade management that our cu

I doubt there is a single answer, it all depends on where your data
center is located.
Look at power grid, telecom, flood plain, tornado/hurricane paths, fault

Your idea of staying far enough away to ensure relative safety from a
regional issue sounds about right.

Lizette,
It depends! (Of course)
What are the naturally occurring problems within the primary data
centers location? Things like power grids, weather problems,
transportation issues, telco coverage, etc.
What are the business reasons for a PPRC setup over an XRC setup?
What is the cost of downt
IBM answer #3 - It depends
It depends on the risks in your operating environment.
If you're in Oklahoma and the primary threat to life and limb stems from
tornadoes then 10 miles might be enough.
If you're located on the coast of the Gulf of Mexico and the threat is
hurricanes, then 10 miles do
