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.
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.
To configure the system, you can use either a software- controlled on-board RAID Controller (LSI Embedded
MegaRAID
TM
) or a hardware-controlled optional RAID Controller (N8103-128/129/130/134/135).
To use this RAID System, jumper settings on motherboard and backplane are required.
For the location of the jumpers and setting, refer to the following.
Jumper settings on the motherboard and backplane required to use the RAID Controller (LSI Embedded
MegaRAID
TM
) or optional RAID Controllers (N8103-128/129/130/134) are described in the images below.
