I'm using ReiserFS and ext3 (both in production), and am about to move
from reiserFS to ext3. Except for special purpose (e.g. my MP3 base, and
an thousends off small files (1-10k) box)

IMHO, don't use SuSE, pick one of the real RPM based distributions.
If you want everything provided go for RedHat or Mandrake, if you want a
real server (and know how to compile your kernel) go for trustix.

Some more comments:
- don't use striping on RAID5. It is not going to work (well, if you
  have two RAID5 sets it will, but that's a waste of disk space)
- this ony appiles to my bad expirience with the 6xxx 3ware controllers:
  test wether softRAID with the linux kernel is not faster than the
  hardware RAID
  (well, you can not boot from softRAID as comfortable as you can from
   hardware RAID)
- install the 3ware tool, the 3dm is a deamon that is configurateable
  from a web page (only runs on localhost, and has (for sure) some
  security holes). It can send mails on errors, too.
  (AFAIR the install script is realy broken, don't run it, do it by
   hand)
- with a 2.4.xx kernel you do not need a special driver
- I've a 6800 for sale. i switched my home filebase over to 3 promise
  controllers. They can do powersaving while I'm at work.
