Hardware raid not detected while installation

[dos_killer]

i have two hard disks on my server and a raid controller...
i have configured it to work as raid 0 for my purpose and during the boot process it shows that it 1 logical volume has been created

now im trying to install ubuntu server 11.10 on it but when it asks to partition disks, it shows the disks separately ? ...
should they not appear the same ? why is my RAID not detected ??

im using HP Proliant Server ml110 g6...and there is no other OS installed on the system...this is a fresh installation on a new server
details of the raid controller - HP Embedded Smart Array B110i SATA RAID Controller (RAID 0/1/10)

Did you fix this?? Im Having the same problem with ML110 G5.

Have you searched for drivers in case it doesn't recognize the controller?

Also, lots of these controllers these days are not a true hardware raid, but instead a fakeraid. I would also do a research on that topic, and if it shows that it is fakeraid, it's better to use software raid with mdadm.

On top of all that, I have to ask: raid0 for server? Even if it's only a home server, why raid0? If one disk goes, everything is gone.
