Using Serial ATA RAID

This motherboard adopts VIA VT8237R Plus southbridge chipset that supportsSerial ATA (SATA) hard disks. You may install two SATA hard disks on themotherboard for storage devices.For optimal performance, please install identical drives of the same model andcapacity when creating a RAID set.

1. Introduction

RAID BasicsRAID (Redundant Array of Independent Disks) is a method of combining twohard disk drives into one logical unit. The advantage of an Array is to providebetter performance or data fault tolerance. Fault tolerance is achieved throughdata redundant operation, where if one drives fails, a mirrored copy of the datacan be found on another drive. This can prevent data loss if the operating sys-tem fails or hangs. The individual disk drives in an array are called members.The configuration information of each member is recorded in the reserved sector.that identifies the drive as a member. All disk members in a formed disk arrayare recognized as a single physical drive to the operating system.

Hard disk drives can be combined together through a few different methods.The different methods are referred to as different RAID levels. Different RAIDlevels represent different performance levels, security levels and implementa-tion costs. The RAID levels which the VIA VT8237R Plus SATA RAID Host Con-troller supports are RAID 0, 1 and JBOD.

RAID 0 (Striping)RAID 0 reads and writes sectors of data interleaved between multiple drives. Ifany disk member fails, it affects the entire array. The disk array data capacity isequal to the number of drive members times the capacity of the smallest member.The striping block size can be set from 4KB to 64KB. RAID 0 does not supportfault tolerance.

RAID 1 (Mirroring)RAID 1 writes duplicate data onto a pair of drives and reads both sets of data inparallel. If one of the mirrored drives suffers a mechanical failure or does notrespond, the remaining drive will continue to function. Due to redundancy, thedrive capacity of the array is the capacity of the smallest drive. Under a RAID 1setup, an extra drive called the .spare drive. can be attached. Such a drive will beactivated to replace a failed drive that is part of a mirrored array. Due to the faulttolerance, if any RAID 1 drive fails, data access will not be affected as long asthere are other working drives in the array.

JBOD (Spanning)A spanning disk array is equal to the sum of the all drives when the drives usedare having different capacities. Spanning stores data onto a drive until it is full,then proceeds to store files onto the next drive in the array. When any diskmember fails, the failure affects the entire array. JBOD is not really a RAID anddoes not support fault tolerance.

2. Installing SATA Hard Disks

STEP 1: Install the SATA hard disks into the drive bays.STEP 2: Connect one end of the SATA data cable to the motherboard’s primary

SATA connector (SATA_1).STEP 3: Connect the other end of the SATA data cable to the master SATA hard

disk.STEP 4: Connect one end of the second SATA data cable to the motherboard’s

secondary SATA connector (SATA_2).STEP 5: Connect the other end of SATA data cable to the secondary SATA hard

disk.

3. BIOS Configuration

Enter BIOS Setup program1. Enter the BIOS setup program by pressing the <Del> key during the POST

(Power-On Self Test ).2. Select the Integrated Peripherals item, then press <Enter>.3. Select the VIA OnChip IDE Device menu.4. Switch the SATA Mode option to [RAID].5. Press <F10> to save the BIOS setting and exit the BIOS setup program.

Enter BIOS Configuration UtilityWhen the system powers on, the following information will appear on screen.Press the <Tab> key to enter BIOS configuration utility.

Press <Tab> key into User Window!

The main menu of BIOS configuration utility is as below:

A. Create ArrayThe VIA VT8237R Plus supports RAID 0, RAID1 and JBOD mode. Follow thesteps to create RAID.

a. Guide to Configure RAID 0STEP 1: Select the option Create Array in the main menu of BIOS configura-

tion utility, then press <Enter> key.STEP 2: Select the option Array Mode, then press <Enter> key to display the

pop-up menu of RAID system setting.STEP 3: Select RAID 0 for performance from the menu and press <Enter>.

From this point, you may choose to auto-configure the RAID array byselecting Auto Setup for Performance or manually configure the RAIDarray for striped sets. Please continue with the next step if you want tomanually configure the RAID array. Otherwise, proceed to step 3-4.3-1.Select the option Select Disk Drives, then press <Enter>. Use arrowkeys to select disk drive(s), then press <Enter> to mark selected drive.An asterisk is placed before the selected drive.3-2.Select the option Block Size, then press <Enter> to set array blocksize. A list of valid array block sizes are displayed on a pop-up menu.Use arrow keys to move selection bar on items and press <Enter> toselect.3-3.Select the option Start Create Process and press <Enter> to setuphard disks for RAID system.3-4.Then the confirmation message appears:The data on the selected disks will be destroyed. Continue? (Y/N)Press <Y> to confirm or <N> to return to the configuration options.



7

b. Guide to Configure RAID 1STEP 1: Select the option Create Array in the main menu of BIOS configura-


pop-up menu of RAID system setting.STEP 3: Select RAID 1 for data protection from the menu and press <Enter>.

From this point, you may choose to auto-configure the RAIDarray byselecting Auto Setup for Data Security or manually configure the RAIDarray . Please continue with the next step if you want to manually con-figure the RAID array. Otherwise, proceed to step 3-3.3-1.Select the option Select Disk Drives, then press <Enter>. Use arrowkeys to select disk drive(s), then press <Enter> to mark selected drive.An asterisk is placed before the selected drive.3-2.Select the option Start Create Process and press <Enter> to setuphard disk for RAID system.3-3.Then the confirmation message appears:Save the data on source disk to mirror after creation? (Y/N)Press <Y> to confirm or <N> to return to the configuration options.

c. Guide to Configure JBODSTEP 1: Select the option Create Array in the main menu of BIOS configura-


pop-up menu of RAID system setting.STEP 3: Select RAID SPAN for capacity from the menu and press <Enter>.

From this point, you may choose to auto-configure the RAID array byselecting Auto Setup for Capacity or manually configure the RAIDarray for striped sets. Please continue with the next step if you want tomanually configure the RAID array. Otherwise, proceed to step 3-3.3-1.Select the option Select Disk Drives, then press <Enter>. Use arrowkeys to select disk drive(s), then press <Enter> to mark selected drive.An asterisk is placed before the selected drive.3-2.Select the option Start Create Process and press <Enter> to setuphard disk for RAID system.3-3.Then the confirmation message appears:The data on the selected disks will be destroyed.
