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 depending on the RAID level.
•
If SW RAID controller or an optional RAID controller (N8103-176/188) is used, the RAID system cannot be
built in RAID5/RAID6/RAID50/RAID60.

RAID 10

•
Use SAS/SATA hard disk drives or SSDs that have the same capacity and rotational speed.
•
RAID 10 using a hard disk drive of 2 TB or more cannot be supported if SW RAID controller is used.
•
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 are installing the OS manually, use the RAID system configuration utility. For details of the utility,
see Chapter 2 (5. RAID System Configuration) in "Maintenance Guide" or the manual supplied with the
optional RAID controller.
