I've dealt with databases with about 100 million records
(100Gb of data/indexes), using Oracle, and i'm glad we did.
If you database is 5 times larger than our largest one, you definitely
you need Oracle or something high end.

Sounds good.

That's not much RAM for a database that size. However it could
be adequete.

In general you need at least 3-4 times the hard disk space required
for you data for indexes, temp storage and growth.

Red Hat Advanced Server is better - it has Oracle patches for better
asynch i/o performance.

You probably mean store the data on multiple hard disks. That's good.
Different db's make little sense.

A bad idea. We also use and like MySQL, but definitely this is
a different league. Also get a good DBA, you sound as if you will need one.

Doing such databases can be very profitable (if you are the vendor), but
you need to get some skilled people to work with you. The selection of
hardware available for the task is very wide depending on your
price/performance. Hardware vendors such as IBM and HP are
Linux friendly and have the expertise to advise you better. Don't ask
box pushers like Dell - they don't have the right knowledge.
