It's supported. I don't know about your motherboard. I have a
Promise Ultra 100 on an older MB. Just make sure your power
supply is up to it. I patched a 2.2.18 kernel to add support
for the Ultra 100. Beyond that it's stock. Note, I had to make
the /dev/hd[efgh]* devices. Sofar I haven't done anything with
raiding them. A friend's experience shows that raid 0 and 1,
striping and mirroring, works quite nicely and fast while raid
5 is slow. This is due to the CPU having to calculate the raid
5 checks blocks.
The major issue I've run into is finding places for my 6 HDs.
I ended up using a couple plates of metal to make a short tower
to hold 4 of them in front of a fan.
This is the df from my system.
