Really? They could maybe start with their DBAs... True, I *have* met a few DBAs who don't know how disk drives work, but I like to think that such DBAs are becoming fewer in number (or at least do not survive for long). Okay, maybe I live in a fantasy world, but at least it's a nice one. ;-) In any event, I would think that most DBAs have the necessary skills to tell a good storage solution from a collossally bad one. And sometimes even to identify those which are "supported" or "not supported" by Oracle.
The places I've worked storage is a system admin area not a dba area. This has not always been pleasant. I suspect it is quite common. It isn't unreasonable for the TA to go to his in-house 'experts'. Unfortunately most sysadmins measure storage in GB, not your measure of GB/min or even better a measure of IO operations/sec
That said, however, many of the more "curious" technical architecture decisions I have observed have something else in common (aside from over-reliance on "vendor input"). They have involved selections of server platforms or storage arays without obtaining input from the DBAs. Hmm...
of course and to counter my own argument somewhat, often the SAs are in the dark as well...
Of course even when you do employ experts/consultants and extensive consultation things can still look rather unfortunate http://news.bbc.co.uk/1/hi/health/5233604.stm
