Product Overview
Silicon Image’s SATARaidTM provides Serial ATA Software
RAID including Striping and Mirroring to enhance the
industry’s first proven PCI-to-SATA host controller product.
Two major challenges facing the storage industry today
are keeping pace with the increasing performance
demands of computer systems by improving disk I/O throughput and providing data accessibility in
the face of hard disk failures. With the SiI 3112 / Sil 3512 Serial ATA host controller and SATARaid, both of
these problems are solved.
RAID Striping greatly improves hard disk I/O performance by concurrently Striping data across mul-
tiple drives. RAID Mirroring enables users to enjoy the confidence of data availability regardless of
a single disk failure as data is simultaneously written to two drives.
Standard with SATARaid software is a Graphical User Interface (GUI) that provides easy-to-use configu-
rations for the different RAID Sets supported.
SATARaid Features
• RAID 0 and 1
• Hot Spare and On-line Mirror Rebuilding
• System GUI Monitoring Utility:
- Displays/Logs/Alerts Users to Vital RAID Set Information

RAID Explained
RAID - Redundant Array of Independent Disks
RAID technology manages multiple disk drives to enhance I/O performance and provide redundncy in
order to withstand the failure of any individual member, without loss of data.
SATARaid provides two RAID Set types, Striped (RAID 0) and Mirrored (RAID 1).
Disk Striping (RAID 0)
Striping is a performance-oriented, non-redundant data mapping technique. While Striping is discussed
as a RAID Set type, it is actually does not provide fault tolerance. With modern SATA and ATA bus mas-
tering technology, multiple I/O operations can be
done in parallel, enhancing performance. Striping
arrays use multiple disks to form a larger virtual disk.

This figure shows a stripe set using three disks with
stripe one written to disk one, stripe two to disk two,
and so forth.

Block 3
Disk Mirroring (RAID 1)
Disk mirroring creates an identical twin for a selected disk by having the
data simultaneously written to two disks. This redundancy provides instan-
taneous protection from a single disk failure. If a read failure occurs on one
drive, the system reads the data from the other drive.

3 . C R EATING/ D EL ETING R A ID SETS
Creating and deleting RAID sets is a function found in the BIOS. During bootup, the following message
will appear, pausing for a few moments to allow the user to choose what to do:
Press <CRTL-S> or F4 to enter RAID utility
An easy-to-use screen will appear with the following choices in the top left:
Create RAID Set
Delete RAID Set
Rebuild RAID Set
Resolve Conflicts
Below this will be listed the drives currently installed on the system.
The top right half of the screen displays directions and comments for the user. The bottom right half lists
the command keys:
Arrows up and down are Select Keys
ESC takes the user to the previous menu
Enter selects the user’s choice
Ctrl-E exits the utility
Creating RAID Sets
Becuase SATARaid supports two drives, creating RAID Sets is a simple procedure.
1. Select “Create RAID Set.”
2. Choose either a “Striped” or “Mirrored” RAID Set.
3. Select if you want the utility to Auto Configure the RAID Set or if you want to manually configure
the RAID Set. For Striped Sets, you can change the chunk size. For Mirrored Sets, you assign
which is the Source and Target drives, as well as if you want Disk Copy.
What is Disk Copy? If the disk assigned as the source disk already has been partitioned and has
data stored on it, and then a second disk is added for redundancy, the data on the source drive can
be copied to the destination drive, so the disks are identical, and all subsequent data will be written
to both drives as a Mirrored set. If, however, the source disk does not have data already stored on
it, there is no need for Disk Copy.
4. The utility will ask “Are You Sure?” before completing the configuration.

Deleting RAID Sets
1. To remove one or more RAID sets, select “Delete RAID Set.”
2. Select desired set and press Y when asked “Are You Sure?”
Resolving Conflict
When a RAID set is created, the metadata written to the disk includes drive connection information
(Primary Chanel, Secondary Channel). If, after a disk failure, the replacement disk was previously part
of a RAID set (or used in another system), it may have conflicting metadata, specifically in reference to
the drive connection information. If so, this will prohibit the RAID set from being either created or rebuilt,
In order for the RAID set to function properly, this old metadata must be first overwritten with the new
metadata. To resolve this, select “Resolve Conflict” and the correct metadata, including the correct drive
connection information, will be written to the replacement disk.

The creating and naming of partitions is something done within the Windows operating system. And
while Windows XP/2000 and Windows NT both use the Disk Management window, there are enough
nuances that make it important to follow the procedure specifically for the appropriate operating system.
The procedure for Windows 98/Me is significantly different than the others.

Windows XP/2000 Operating System
Before creating any partitions, RAID sets must first be created/dissolved using the BIOS RAID Utility.
Once completed, continue booting Windows.
Once Windows is running, open the Disk Management window located at:
Control Panelꢀ Administrative Toolsꢀ Computer Managementꢀ Storageꢀ Disk Management
Something similar to the following window should appear:
SECTION 1
SECTION 2
SECTION 3
SATA RAID Function

Download from Www.Somanuals.com. All Manuals Search And Download.
This window has three main sections:
SECTION 1: System listing of all formatted and available disks/RAID Sets.
SECTION 2: Report of physical connection of disks/RAID Sets.
SECTION 3: Report of partition status, disk letter, and volume name.
Initial Window
In SECTION 2, every disk should report as:
Basic
Disk Size (the actual available disk space will be reported here)
Online
Instead of “Basic,” a disk may also report as either “Unknown” or “Dynamic.”
If the disk reports as “Unknown,” right-click on the disk (SECTION 2) and click on Write Signature.
At this point, a window will appear with the disk in question (all “Unknown” disks may appear in this win-
dow). Make sure the box next to each disk is checked, then click OK.
The disk should now report as “Basic.”
If a disk reports as “Dynamic,” right-click on SECTION 2 of that disk, and click on “Return disk to
Basic...” Within seconds the disk should report as Basic.
Creating Partitions
In SECTION 2, the disk order corresponds directly to the order the Sets appear in the BIOS. Therefore,
the first Unallocated Partition represents Set 1, and so on.
1. At this point, there should be three disks with Unallocated partitions. Right-click on the partition of
the first disk and click on “Create Partition.” The “Create Partition Wizard” should appear.
1. The first window is an introductory window to the Wizard. Click Next.
2. The second window designates the partition as a primary partition. Click Next.
3. The third window designates the partition size. Since this is a Striped RAID set, utilizing 2
disk drives, the size of the partition should be approximately double the size of a single
disk drive (assuming all disks are of identical size). Click Next.
4. The fourth window designates the drive letter of the partition.

5. The fifth window allows the user to label the volume name, and choose the type of format-
ting to take place upon the creation of the partition. Choose which ever drive letter is
desired (the lowest possible value is automatically entered), name the volume whatever is
desired (suggestions being something generic such as STRIPED SET or something specif-
ic to use such as FINANCIAL, CRITICAL, MISCELLANEOUS, etc.) then check the box
next to “quick format.” Click Next.
6. The sixth window is a summary window listing all of the selections made. Click Finish.
Depending on the size of the disk drive(s) included in the partition, the partition should change from
“Unallocated” to “Healthy” with its name and drive letter reported as well in a matter of minutes or less.
Do not attempt to create a partition for the next disk until the disk currently being formatted is complete
and reports Healthy.
Also note that once the disk reports Healthy, it appears in the listing in SECTION 1 with all of its perti-
nent information as well.
2. Repeat this procedure for the partition of the second and third disk.
3. Close the Data Management window by clicking on the small boxed “X” in the top right corner of
the window.
4. Click on the “My Computer” icon on the Desktop. The three new drives should now be visible and
properly named. Data may now be stored to each of these disks if desired.

The Device Location refers to
how each physical disk was
reported in the BIOS RAID utility.
The Members tab of this window reports the device identification (corresponding with the information in
the BIOS) and the State of each device.
Besides reporting information, the Members tab of a Mirrored set allows the user to remove a specific
drive from that set, as well as add a designated Spare drive to a Mirrored set that has experienced a
disk failure. A drive can NOT be removed from a Striped set as this would destroy all data. Note that
when a Mirrored Set is first created, the State of the “destination” drive may report as Rebuild for as
much as 30-90 minutes depending on the size of the disk.
