Think of Exadata as being just another Oracle DB with bells and whistles (Oracle Engineered System).
Only Oracle will set it up and send it's personnel to help you and are provide prompt assistance in case of h/w failure.
Been working with Exadata for 10+ years now and the level of support provided by Oracle has been wonderful (because of the $$$ invested).
But other than that, read, read and read. Just be aware that you will need to learn new tricks (patching etc.) and also how it is set up (cell server, cache, DB server).
But once you start getting hands on it will be easier to handle.
FYI: the end users will be the hardest to please as they believe Exadata = "Fast" :D
Good luck with that ;o)

Hello, John : Exadata' foundations are built on top of some others technologies, namely ASM, special indexes (indexes where the 'device' containing the data is know, so only THIS device neeed to be read, avoiding A LOT OF I/Os), colunar compression (and some other compression techniques) and caching, among some others...
So, imho, first of all you NEED to understandand PROFOUNDLY this technoligies, together with RAC (RAC is Optinal but is very, very, very Common in EXADATA environments....
When you feel yourself confident with these RDBMS-related technologies, then you will be Ready to read the good books about EXADATA and learn about (the many) Exadata software specialties...
Success and Best Wishes,
