Everything I've read about Hadoop seems like exactly the technology we need to make our enterprise more scalable. We have terabytes of raw data that is in non-relational form (text files of some kind). We're quickly approaching the upper limits of what our centralized file server can handle and everyone is aware of this. Most people on the tech team, especially the more junior members of the tech team are all in favor of moving from the central file system to HDFS. The problem is, there is one key (most senior, etc.) member of the team who is resisting this change and every time Hadoop comes up, he tells us that we could simply add another file server and be in the clear.
So, my question (and yes, it's really subjective, but I need more help with this than any of my other questions) is what steps can we take to get upper management to move forward with Hadoop despite the hesitation of one member of the team?

Why are you in favor of this move?
Unless you have a technical person who is a decision maker chances are they don't care about who favours what. They care about:
Would moving to this new system require re-organization or restructuring things? This can be very expensive.
Being a programmer I understand that everyone (except one) may be in favor of something, but the business side of me is saying there needs to be justification for it.
Create a case for moving to the new system. Some good things to include would be:
Basically, to sum it up, take the time to do the research, show facts and figures, present your case.
N.B. Do not make one of your reasons "b/c the team is in favor of it", b/c it will not fly!
