I have a HP DL320 with built-in SATA RAID. In the bios I have the array built (two SATA drives setup as "Mirror"), set to active and marked "bootable". The server POST shows the array there but when I run the Red Hat ES setup it shows both drives at the partitionaing section. Is this right? I thought it would just show one drive since I'm running hardware mirroring? Do I just install to drive 0? Any input appreciated.
While we are on the subject is RAID 0 or 1 favored in a two drive server? This is going to be a DHCP/DNS/SMTP server.
