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 (N8103-205/206/210) is used, the RAID system
cannot be built in RAID5/RAID6/RAID50/RAID60.

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

are installing the OS manually, use the RAID system
configuration utility. The utility can be run during POST which starts immediately after the server is
turned on. For details, see

in "

manual supplied with the optional RAID controller.
Important
Do not change the RAID system mode to hibernate.
A mix of SAS and SATA drives cannot be used within the RAID system.
