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 used in the RAID system
contains valuable data, be sure to back up 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.
To build a RAID system, change the jumper switch on motherboard and backplane, as shown below.
(a) Using the Software RAID (SW RAID)
Enable SW RAID by changing jumper setting on motherboard.
Jumper on motherboard (SWRAID)
