1.10.2 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 on-board RAID controllers or the optional RAID controllers (N8103-171/149) are used, the RAID system
cannot be built in RAID5/RAID6.

•
Use SAS/SATA hard disk drives or SSDs that have the same capacity and rotational speed.
•
When installing an OS in your RAID system, you can easily complete the setup process, including RAID
configuration and OS installation, by using EXPRESSBUILDER. If you want to install the OS manually, use
the RAID system configuration utility (WebBIOS or SuperBuild utility). The utility can be run during POST
which starts immediately after the server is turned on. For details, see Chapter 2 (4. RAID System
Configuration) in "Maintenance Guide" or the manual supplied with the optional RAID controller
(N8103-171/149/150/151/152/160).

• Do not change the RAID system mode to hibernate.
• Build a disk array in the RAID system using hard disk drives that have the
same specifications (capacity, rotational speed, and interface).
