Custom Configuration - HP D5970A - NetServer - LCII Configuration Manual

Chapter 4
For each array, the system looks to see if you have asked to implement
redundancy (checked the Redundancy box). If you are not using
redundancy, all logical drives are assigned RAID level 0.
If an array contains two drives, and you checked Redundancy, the logical
drive is assigned RAID level 1.
If a group contains three to five drives, and you checked Redundancy, the
logical drive is assigned RAID level 5.
If an array contains only one drive, the logical drive is assigned RAID
level 0. (No redundancy is possible on a logical drive containing just one
physical drive.)
Automatic configuration does not create hot spares. You must create your
hot spares before you begin automatic configuration.
CAUTION For performance reasons, non-hot-swap devices should not be
combined in arrays with hot-swap disk drives. If your non-
hot-swap devices have the same capacity as your hot-swap
disk drives, do not use Automatic mode. See "Custom
Configuration," next in this guide, for recommendations on
making best use of your non-hot-swap devices.
If Automatic configuration will suit your needs, you can proceed to Chapter 5,
"Configuration." However, you are encouraged to read the entire planning section
to determine whether or not a custom configuration would better meet your
needs.

Custom Configuration

To plan a custom configuration, you will do the following:
Plan your non-hot-swap devices (only if integrated HP NetRAID is
enabled for SCSI B)
Plan your arrays
Plan hot spares
Decide the rebuild rate
Plan logical drives
