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 10
RAID 50

• In the RAID system, all the hard disk drives in an array group must have the same capacity, interface type,
and rotational speed.
•
EXPRESSBUILDER helps you to install the OS to a RAID array easily.
•
If you want to install the OS manually, use RAID Configuration Utility at POST (Ctrl-R or H). For details,
see Chapter 2 (4. RAID System Configuration) in "Maintenance Guide" or the manual provided with the
optional RAID controller (N8103-176/177/178).

• Build a disk array in the RAID system using hard disk drives that have the
same specifications (capacity, rotational speed, and standard).
