5-2 Chapter 5: RAID configuration
5.1.2 Installing hard disk drives
The motherboard supports Serial ATA and SAS (KFN5-Q/SAS model only)
hard disk drives for RAID set configuration. For optimal performance, install
identical drives of the same model and capacity when creating a disk array.
To install the SAS hard disks for RAID configuration:
1. Install the SAS hard disks into the drive bays following the instructions
in the system user guide.
2. Connect a SATA signal cable to the signal connector at the back of
each drive and to the SATA connector on the motherboard.
3. Connect a SATA power cable to the power connector on each drive.
To install the SAS hard disks for RAID configuration (KFN5-Q/SAS model
only):
1. Install the SAS hard disks into the drive bays following the instructions
in the system user guide.
2. Connect the SAS connector at the back of each drive and the 4-pin
power connector on the SAS cable.
3. Connect the mini-SAS connector on the motherboard.
Refer to Chapter 5 for details on entering and navigating through the
BIOS Setup.
RAID 5 stripes both data and parity information across three or more hard
disk drives. Among the advantages of RAID 5 configuration include better
HDD performance, fault tolerance, and higher storage capacity. The RAID 5
configuration is best suited for transaction processing, relational database
applications, enterprise resource planning, and other business systems.
Use a minimum of three identical hard disk drives for this setup.
If you want to boot the system from a hard disk drive included in a
created RAID set, copy first the RAID driver from the support CD to a
floppy disk before you install an operating system to the selected hard
disk drive. Refer to Chapter 6 for details.
