...but I think this is a part of the point. It is likely
you're talking about Amazon and yes, those guys are
exceptional. It takes a team of this talent-level (
and some very close support of Oracle) to do something
as complex as a 48 node RAC cluster.
The thread originated as a rhetorical question of how
realistic such a thing would be. And, my $.02 is
that it is not very realistic, even though folks
like AMZN do it (sometimes man bites dog).
To address the actual marketing fluff that Sun
put up which spawned the whole thread, one should
consider total price. The piece pitted a large IBM
SMP against a 64 node Opteron-based Sun RAC cluster.
Presuming those are 2way Opterons, the list Oracle
license cost would be $7,680,000. Then you have to
figure out how to maintain it. No rolling upgrade
(yes, I know there is Data Guard with SQL apply in
10g but that means 2 clusters now). And most
critical updates (e.g., CPUJan2005) specifically
state that they cannot be done in a rolling
fashion.
I wont bring up scalability, because "good
applications" do scale well with RAC...
and there is data-dependent request routing
(application partitioning) if all else fails.

Oracle - Sun Grid Computing
While IBM's fastest computer costs you $5,041,771, for a
Grid of 64 Sun Opteron Servers you spend only $504,567.
You can adopt Grid technologies with minimal investment,
zero disruption, and fast ROI, starting with three steps:
* Standardize on low-cost, modular servers and
storage with Sun Grid Rack Systems.
* Consolidate distributed servers and storage with
Oracle Database and Real Application Clusters.
* Automate server and database with easy-to-use
management software from Sun and Oracle.
Of course, you need to be willing to spend less.

I have never put my hands on >2 node Oracle OPS-RAC
Cluster.
I have only heard of a few *real world* production 4
node Oracle RAC Clusters.
I can't really imagine the *true* reality, simplicity
and power of 64 node RAC cluster.
Maybe I just not a forward thinker....but I think this
would be a big pain.
Man...I love Oracle more just as much as anyone, but
they need to put a cooler on their marketing dept.
Sad thing is that those who love and know Oracle most,
are most cynical about their advertisements!

Was talking to some co-DBA's today...one DBA said a
funny thing;
The only "silver bullet" Oracle has, is their User
Manuals!"
The more you read...the more you know...and the less you
believe...
