Understanding RAID Levels

During installation, you configure your logical drives by running a disk array
configuration utility. Each of the logical drives you define must have an assigned
RAID level. Each RAID level has different advantages in terms of performance,
redundancy, and capacity. HP NetRAID-1M and 2M adapters support both basic
array and spanned array configurations.
Basic arrays have logical drives that are contained entirely within the
array. Basic array configurations use RAID levels 0, 1, or 5.
