1.16.2 Notes on setting up a RAID System

Note the following points when setting up 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.


Use SAS/SATA hard disk drives or SSDs that have the same capacity and rotational speed.

EXPRESSBUILDER helps you to install the OS on a RAID array easily.

If you want to install the OS manually, use a RAID System Configuration utility (Ctrl-R or HII). The utility
can be run during POST which starts immediately after the server is turned on. For details on the
procedure of configuring a Logical Drive, see Chapter 2 (5. RAID System Configuration) in Maintenance
Guide or the manual supplied with the optional RAID Controller (N8103-176/177/178).
