[CentOS] CentOS on HP DL360e with B120i

I am trying to install CentOS5 on a new HP DL360e G8 with B120i disk
controller. It appears that a proprietary HP driver is needed for it.

I found a useful description at http://www.linuxhelp.in/2013/08/Installing-centos-on-HP-Proliant-DL360e-Gen8-with-B120i-controller.html

I have a pair of hard drives to use as a RAID1 mirror.

My question to people who may have been this way already is: is it worth
my fiddling around with that procedure to get the RAID controller working,
performance-wise, or might I just as well use AHCI mode with kernel mdraid?

I normally use Supermicro with AHCI and mdraid quite happily, but the
customer wanted HP :(

Cheers
Tony
