Notice
Observe the following notes on configuring a RAID System:
The installed hard disk drives (SAS drives or SATA drives) must the same capacity and
the same rotational speed. (The minimum number of required disks depends on the
configuration of RAID (Redundant Arrays of Inexpensive [Independent] Disks).)
Select/set a RAID level.
Onboard RAID Controller: RAID0, RAID1, or RAID10
Optional RAID Controller: RAID0, RAID1, RAID5, RAID6, or RAID10
When installing a system in an internal hard disk drive, you should use "Express Setup" to perform
all the procedures for RAID System configuration, OS installation, and then OS setup.
Use Express Setup even when not installing a system. Start Express Setup, select [OS Selection]
-[Others]. The installer automatically performs all the procedures for RAID System configuration,
and then maintenance utility installation.
When making the setup in manual mode, use the RAID System configuration utility in the chip on
the board. You can start the utility during execution of POST that automatically starts immediately
after you turn on the POWER/SLEEP switch. For details, see the online document in the NEC
EXPRESSBUILDER DVD provided with the server. For details on the data transfer rate, RAID,
and RAID System configuration, see the manual provided with the RAID Controller as well as the
online document.
IMPORTANT:
When N8103-109/116A/117A is installed, do not let the system
enter hibernation or standby mode.
Configuring RAID System by SATA hard disk drives together with
SAS hard disk drives is not permitted.
