I configured a new HP server with 8 drives and an Array p410i controller. I setup two drives RAID 1 so that if one failed i would still have the OS running. The remaining 6 drives I configured RAID 5 because the utility gave me an option RAID 5 or RAID 1. Should I have configured as RAID 10 vs. RAID 15? Is performance going to be an issue?
Also, last week, I had drive failure on the RAID 1 (OS). I assumed if I lost one drive that I would still be functioning but the server would not boot. I reset the drive and it rebuilt and everything came back up fine. However, I have no confidence in this configuration. The server is not in production yet but my intent was to make it the the role domain controller, which I still like to refer to as PDC even though there is no such thing in W2k8 anymore, and simply use as a File sharing print server. What would be the ideal config using the Array controller and drives that I have?
