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 -- Tony Mountifield Work: tony at softins.co.uk - http://www.softins.co.uk Play: tony at mountifield.org - http://tony.mountifield.org
