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.


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
