Notes on Building RAID System
Note the following points when building a RAID System.
The number of hard disk drives required varies in each RAID level.
If the optional RAID Controller N8103-176 is used, the RAID System cannot be built in
RAID5/RAID6/RAID50/RAID60.

RAID 5
RAID 6
RAID 10
RAID 50
RAID 60
In the RAID System, all the hard disk drives in a group (pack) must have the same capacity, interface type,
and rotational speed.
If you intend to install the OS to the RAID System, the process from RAID configuration to OS installation
can be easily completed by using EXPRESSBUILDER.
If you wish to install the OS manually, use RAID System Off-line Utility (Ctrl-R or HII). For details, see
Chapter 2 (4. RAID System Configuration) in "Maintenance Guide" or the manual supplied with the
optional RAID Controller (N8103-176/177/178).
Up to 31 logical drives can be created. Do not create 32 or more logical drives
