Getting in on this one late, saved the emails for a rainy day which is
ironically right now.

A few questions:

We have a production 4.1.1 box that is acting as a mail server.  We are
wanting to beef this box up a bit for a little more survivability.

1) If we put in a newer hardware raid card does the os/kernel still need a
driver to see it?  Or does a hardware raid solution eliminate the need for
any drivers.  We are just a bit concerned due to our OS being a bit behind
and thinking that our raid options might be limited or very antiquated.  I
realize that the original poster said that "Yes, the RAIDing is completely
transparent to the OS.", which confusing me as to why there is a supported
raid card list.

2) Can a mirror be made out of an existing drive.  I have heard the that the
Adaptec 2100A can make a mirror off of existing data, but alas this is not
supported by FreeBSD as they recommend the 2400A.

Any insight would be great...
