No.

Not really, and it may be slower.

One for OS, "one for Database" as in the binary?  Put the binary on

disk than the data storage areas).  The performance is much better
that way.

Some people report that Linux is actually faster than Solaris on the
various SPARCs.  I have my doubts, but I haven't tried.
