Use of Internal Hard Disk Drives in the RAID System
This section describes how to use the Hard Disk Drives installed in the HDD cage at the front of the server in
the RAID System.
Important
•
If you use Hard Disk Drives in the RAID System or change the RAID
level, initialize the Hard Disk Drives. If the Hard Disk Drive contains
valuable data, be sure to backup the Hard Disk Drive before installing
the RAID Controller and configuring the RAID System.
•
Do not change the mode to hibernate when building a RAID System.
Note
In the RAID System, use Hard Disk Drives that have the same specifications
(capacity, rotational speed, and standard) for each Disk Array.
Tips
•
Logical Drives can be created even with only one Physical Device.
•
Understand the characteristics of each RAID Controller such as available RAID
levels or Hard Disk Drives and choose an appropriate RAID Controller.
•
Logical Drives except for RAID0 have a smaller usable capacity compared to
the total capacity of the Hard Disk Drive in the Logical Drive, while disk reliability
increases.
You can set up a RAID system by using the on-board RAID controller (LSI Embedded MegaRAID™).
To use this RAID system, it is necessary to install two Solid State Drives on the server. For details on the
procedure of installing Solid State Drives, refer to
Chapter 2 (1.7 Solid State Drive (SSD))
in this manual.
1.8.1
Enabling a RAID System
You can use the installed Solid State Drives as single solid state drives or as a RAID system.
To set up the installed Solid State Drives as a RAID system, select
Advanced
,
PCI Configuration
, and
Onboard SCSI
from the
BIOS Setup
menu, and then set
Option ROM Scan
to
Enabled
. (For details, refer to
Chapter 2 (1. System BIOS)
in the
“Maintenance Guide”
.)
Tips
The Solid State Drives are set to be used as a RAID system as the factory default.
