In Adaptec speak HostRAID is software RAID. What you have is not
hardware RAID controller. The card is really just a standard SCSI
controller with fake RAID BIOS. Create software RAID devices under
CentOS (and you'll get exactly the same thing as if configuring them in
BIOS and using Adaptec device driver).
