We use Sun and NetApp filers as NAS in a majorly TP environment, but the discussion is the same.

We keep the full Oracle install on local disks. Our load on the local disks is pretty minimal, suggesting that the load generated accessing the binaries is trivial. And that suggests that from a performance standpoint, it really doesn't matter where they live in our environment.

We made the decision to keep them on local drives on each server so that we could make a server stand alone with small local datafiles if we ever needed to. Occasionally it has come in handy but not enough that I would get up on a soapbox and suggest others should do the same.

The storage vendor is certainly going to suggest that you put everything on his equipment -- it can push you to buy more capacity. So ignore the vendor and see how it really fits into your overall operational strategy of product, recovery, testing, etc.
