    Raid Configuration--Help required

    We are installing a new oracle db of size 20gb
    2scsi harddisks of 36gbs each.
    With hardware Raid controller
    which Raid configuration is better
    for our OLAP and Batch processes,
    with oracle 8 database and 40 users.

    Now we are running Raid 5 in another server,
    but hit with performance issues.
    Can we go for Raid 1,0.

    2 disks? The only thing you can do is RAID 0 or RAID 1, not RAID 0+1 nor 5.
