1.18.2 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 (N8103-149) 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.
•
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 the EXPRESSBUILDER. If you wish to install the OS manually, use a
RAID System Configuration utility (WebBIOS). 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, refer
to Chapter 2 (4. RAID System Configuration) in "Maintenance Guide" or the manual supplied with the
optional RAID Controller (N8103-149/150/151).

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