GigaRAID (IT8212) ATA RAID Controller USER’S MANUAL
What is the GigaRAID (IT8212) ATA RAID Controller
This GigaRAID (IT8212) ATA RAID Controller is an excellent product resulting from
Soc concept. It includes one RAID Chip combining CPU, firmware, advanced PCI
controller and IDE controller. Its architecture can provide users a RAID system with
low CPU utilization. When a PC is in high CPU operation or PCI traffic, users won’t
have any penalties for installing RAID system. This is because this system embeds a
local CPU to deal with the RAID function and it’s unnecessary to share CPU’s
performance. It is entirely different from the traditional software RAID system.
Similarly, it also provides users more system stability. It provides users high speed
and integration and low price PC RAID system. Additionally, it also provides PCI
33MHz interface and is compatible with PCI spec. v2.2. It can be easily installed into
the PC system nowadays. Besides, we provide each OS a corresponding driver so
that users don’t have to worry that your systems and the IDE RAID system have any
compatibility issue.
This GigaRAID (IT8212) ATA RAID Controller can support IDE drivers ranging from
the lowest speed of PIO mode drive to the highest speed of ATA/133 drive. Thus,
users can use this characteristic to combine RAID system without any limitations.
Users can use ATA/133 drive and RAID function to achieve the best performance and
get the merit of system’s stability.
The GigaRAID (IT8212) ATA RAID Controller can support the RAID0 (striping),
RAID1 (mirroring), RAID0+1 (striping and mirroring) or JBOD (spanning) mode.
When a system is programmed to the RAID0 mode, it can read or write two drivers at
the same time to enhance the performance. When a system is programmed to the
RAID1 mode, two drivers have the same data and it will prevent data from being
damaged. Once data is damaged, the system will start the rebuild function
automatically and save data back to another new drive. Similarly, this system can use
6
GigaRAID (IT8212) ATA RAID Controller USER’S MANUAL
this data-copying characteristic to let two drivers transmit at the same time and
balance the performance to raise throughput. The RAID0+1 mode uses four drivers
to get the merits of RAID0 and RAID1. As for the JBOD mode, it combines more than
two drives into a drive with a large capacity. This mode does not have the RAID
function and its merit.
Quick Start
This section leads you to quickly establish your RAID system with default settings.
The default settings can meet most people’s requirements. If you need more
advanced optimal, please refer to Setup Utility on page 15 to achieve your goal.
Warning: In order to prevent any data loss resulting from
inappropriate operation, please backup data before you start to
!
install your system.

GigaRAID (IT8212) ATA RAID Controller USER’S MANUAL
The hard drives which are required for the installation
The hard drives, which are connected on the GigaRAID (IT8212) ATA RAID Controller,
can support Ultra ATA/ 133, Ultra ATA/ 100, Ultra ATA/ 66, Ultra ATA/33, EIDE or Fast
ATA-2 drives. Nevertheless, for the best performance, it is suggested that you had
better use the hard drives of the same type and capacity to establish your own RAID
system. After getting ready for the hard drives, you can follow the procedures below
to install the system.
1. Exactly set up every hard drive’s master and slave setting to assure that the
hard drives can surely action and unnecessarily incorrect action of data access
won’t occur.
2. Exactly insert the hard drive’s cables into the connectors on the hard drive and
check if it’s really firmly inserted.
3. Insert every power cable connector into the corresponding hard drive and
check if it’s firmly inserted in a correct direction.
Warning: Because this system can support the hard drives of
Ultra ATA/133, it is suggested that you can use the 80-wire,
!
and efficiency. If the cable is damaged after a period of time, it is also
suggested to buy the cable of the same specification.

GigaRAID (IT8212) ATA RAID Controller USER’S MANUAL
Totally, there are five configurations supported:
RAID level/Type Configurations Number of disks needed
RAID 0 Disk Striping 2 or 3 or 4
RAID 1 Disk Mirroring 2
RAID 0+1 Disk Striping + Mirroring 4
JBOD Disk Concatenation 2 or 3 or 4
Normal None 1 or 2 or 3 or 4
Setup Array for RAID 0:
The GigaRAID (IT8212) ATA RAID Controller allows you to use two, three or four
hard drives to set a RAID 0 (stripe) array. All the hard drives attached on the
controller will be set as array 0. When you create a striped array, files are broken into
64k (stripe size) and stripes are sent to each disk in the array. Selecting RAID 0 can
increase data transfer rate and allow the best overall performance characteristics
because of giving up redundancy.
12
GigaRAID (IT8212) ATA RAID Controller USER’S MANUAL
Setup Array for RAID 1:
The GigaRAID (IT8212) ATA RAID Controller allows two drives to be setup as a RAID
1 (mirror) array or four drives as two arrays. The first mirrored array will be set as
array 0 and the second as array 1. RAID 1 is implemented as mirroring; a drive has
its data duplicated on the other different drive. Selecting RAID 1 can enhance read
performance and allow fault tolerance. A RAID 1 array can thoroughly backup your
files to prevent data loss.
Warning: Two hard drives that form a RAID 1 array have to be
!
attached as the same master or slave hard disks.
Setup Array for RAID 0+1:
A RAID 0+1 (mirror and stripe) array has to be formed by four hard drives. RAID 0+1
is implemented as a mirrored array whose segments are RAID 0 arrays so RAID 0+1
also has fault-tolerance capacity as RAID 1. It not only enhances hard disk access
performance but also backups data to prevent data loss. The formed array is
automatically set as array 0.
Setup Array for JBOD:
The GigaRAID (IT8212) ATA RAID Controller allows you to use two, three or four
hard drives to form a JBOD (Just a Bunch Of Disks) array as array 0. Although JBOD
doesn’t offer other RAID functionality, it makes the hard disks appear to be a single
one by combining the drives into one larger logical one without any capacity loss.
13
GigaRAID (IT8212) ATA RAID Controller USER’S MANUAL
Setup Array for Normal:
You can use the GigaRAID (IT8212) ATA RAID Controller as a normal IDE controller.
The GigaRAID (IT8212) ATA RAID Controller allows you to use one, two, three or four

You can use arrow keys ↑ and ↓ to highlight the drive you want to assign to the
disk array and change the status of Assignments to “Y” by pressing the “space” bar
key.
For the meanings of “Array Mode”, “Drive No” and “Status”, please refer to Define
RAID Menu on page 22. The location of the hard drive is shown at the column
“Channel ID”. “Pri” represents the primary channel and “Sec” represents the
secondary channel. D0 represents a master hard drive while D1 represents a slave
hard drive. Column “Drive Name” shows the model name of the hard drive. Column
“Size” shows the capacity of each hard drive. When a symbol is shown before the
size, the capacity unit is gigabyte.
When you press “Ctrl-Y” keys to save your change, Setup Utility will check if the
setting is legal. If not, an error message will pop up to show you what the error is and
you have to correct the setting. Limitations are shown as below.
Stripe (RAID 0): There isn’t any specific limitation.
Mirror (RAID 1): Two hard drives that form a RAID 1 array have to be attached as the
same master or slave hard disks. For example, primary channel (Pri) master drive
(D0) and secondary channel (Sec) master drive (D0) can form a mirror array; primary
channel (Pri) slave drive (D1) and secondary channel (Sec) slave drive (D1) can form
a mirror array; but primary channel master drive and primary channel slave drive
cannot form a mirror array.
Stripe + Mirror (RAID 0+1): A RAID 0+1 array has to be formed by four hard drives.
24
GigaRAID (IT8212) ATA RAID Controller USER’S MANUAL
RAID 0+1 is implemented as a mirrored array whose segments are RAID 0 arrays.
SPAN (JBOD): There isn’t any specific limitation.
Normal: If a hard drive is not included in an array (Column “Assignment” in the View
Drive Assignment is shown “Free”), this hard drive is regarded as a normal drive.
The existence of the normal hard drive sometimes will influence the array number
user specified. If the Pri/D0, Pri/D1, Sec/D0 or Sec/D1 hard drive is a normal drive,
array 0, 1, 2 or 3 cannot have the array setting respectively. However, you do not
have to concern about this limitation. If Setup Utility finds any conflicts, Array No will
be adjusted automatically. After finishing setting the array, go back to the Define
RAID Menu on page 22 then you will find the Array No is changed. This is because
the existence of the normal hard drive(s) causes the Array No to be adjusted
automatically.
When you press “Ctrl-Y” keys to save your change and your settings checked by
Setup Utility are correct, the following window will appear. You can choose to clear
the boot sector for the newly created array or not. If your RAID Mode is neither Mirror
nor Stripe + Mirror, this array setting is finished then you can click the “Esc” key to go
back to the Define RAID Menu on page 22.
