Yes. It has been my experience that some people think rac is, for want of
a better term, sexy. Its a buzzword they like.
Anyway, I also think that with virtualization coming in more and more, and
the development of private clouds, that scalability is becoming less of an
issue. Its very easy to add more memory and cpu in a virtualized
environment.

Performance scalability is the practical use-case for RAC. Your customer
has self-selected themselves out of that use-case, but apparently they'd
rather spend more money, time, and effort to get to the same place. C'est
la vie...

You can run RAC over iscsi and dnfs according to the oracle
documentation. But I agree with you, sounds like they probably dont need
it that badly, unless its solely for HA.

*Subject: *cost-effective, low-performance options for RAC?
I was asked an odd question today. A customer is determined to use an
Oracle RAC solution, and we are trying to convince them that in their case,
this is too big a solution for what they need. In the meantime, however,
I've been asked a few interesting questions, which I would love to have
your feedback on.
The customer's requirement is for a small database, with only 200 users
maximum, and not concurrent users. We're not looking for high-performance
because the database will not be heavily used.
I've always used fibre connects with Oracle RAC. Is it possible to run
RAC with something other than fibre? I've been asked if we could run RAC
with a single SAS attached disk array.. I'm assuming not, but maybe there
are other lower-cost RAC compatible storage and network connectivity
options.
May I have your feedback on this?
Thanks!
