Not sure about hardware, but I just built a software RAID-1 system a few
days back that boots directly from the Array. This was hand-built kernel
on Debian, but I'd think it'll work under SuSE. IIRC, they include the
MD driver in the kernel.
See Documentation/md.txt in the kernel source.
This is the menu.lst entry I used.
title Debian GNU/Linux, kernel 2.6.20
root (hd0,0)
kernel /boot/vmlinuz-2.6.20 root=/dev/md_d0p1 ro console=tty0
md=d0,/dev/sda,/dev/sdb
Thinking on it, I'm not sure the root directive is "right". I'm not sure
how one would tell grub to look at a RAID device. It may be it only
works because this is RAID-1.
These confirm this:

I'm going for either 4 or 8 ports. The rig should be run by a 10.1
x86_64 system with dual opterons.
The manufacturers I'm looking at are:
Adaptec
Highpoint
3Ware
Promise
Can someone with knowledge about these tell me the pros and cons with
each of them?
