Use of Internal Hard Disk Drives in the RAID System
This section describes how to use hard disk drives installed in the cage in the RAID System.
IMPORTANT:
Making hard disk drives in the RAID System or changing the RAID
level initializes hard disk drives. If the hard disk drive to be
configured in the RAID System has your valuable data stored, make
sure to make a backup copy of the data in another hard disk drive
before installing the RAID Controller and configuring the RAID
System.
You can configure a logical drive with a single physical device.
Use hard disk drives of the same capacity and performance (e.g.,
revolution) for each pack to configure them in the RAID System.
NOTES:
Make sure of RAID levels and hard disk drives available for the
RAID Controller to choose an appropriate controller.
A Logical Drive except for RAID0 increases disk reliability.
However, the actually available capacity becomes smaller than the
total hard disk drive capacity in the Logical Drive.
You can build a RAID System by using the Onboard RAID Controller (LSI Embedded
MegaRAID™, software) or optional RAID Controller (N8103-109/116A/117A, hardware).
