Sorry for the reply and not changing the topic, that was sucky of me.
My apologies please.
So if software raid, wont hinder performance and since I already have
these 4 drives to run Raid, could I boot into Debian Live and run the
software raid and install Xen Hypervisor on that? True I don't get the
added benefits of the DOM0 w/ XCP, but it's still (once fully
configured) a stand alone server that I don't have to worry much about.
Unforunately, I thought it was read Raid like the nForce controller, but
apparently AMD got me on this one. I just bought the Motherboard and CPU
(8 core, but it looks like the DOM0 only detects 5 threads, so maybe I
am better off with the 6 core one I have).
So to run Xen Hypervisor + XCP(??) to manage, would I still get the same
results as running the ISO hypervisor version? (maybe not AS fast)?
Thank you for your time. Should I be using a different thread / mailing
list for this question?

Since I am not very familiar with the Linux side of Raid, do I need
to download the Linux driver (if there is even one available) and put
it on a floppy like Windows?
Motherboard = ASUS M5A97EVO
RAID Controller AMD SB950 chipset
Raid type = 1+0 *aka raid 10
First, please, never reply to maillist with new topic, you causing
wrong thread ordering of messages. If you wish to start new topic,
just write it to maillist address.
Second, there is two issues:
1) Don't use fake raid under linux. Linux has perfect software raid,
which much more reliable and much less troublemaking, compare to fake
raid (you device is fake raid, because it don't actually do anything
with drives).
2) Sad to say, but XCP have very serious issues with raid support. We
using software raid with XCP in our company, but we created very
specifically crafted ISO image with lots ad-hoc fixes and hacks. I
can't recommend do this to anyone, who don't really deep enough in XCP
to do this by himself.
So, you have to opportunities:
a) use real hardware raid (to get raid array as /dev/sda).
b) Do not use raid in anyway (configure fake raid to HBA mode) - use
external storage and don't bother for XCP system drive. If host die,
no data will be lost.
