SATARAID5 User’s Manual
1 Welcome
Silicon Image’s SATARAID5TM software enhances your data storage by combining advanced RAID1 features typically seen on
high-end data systems with low cost/high capacity Serial ATA drives. By using industry standard SATA drives and Silicon
Image Host Bus Adapters, you can achieve extraordinarily low costs while remaining assured that your data is protected
against hardware failure.
1.1
Data Enhancement
1.1.1
Data Security
SATARAID5 provides our highest commitment to data security through the use of RAID architecture to backup and protect
data. RAID levels 1, 5, and 10 provide data security as described in Section TBD below. It also supports sophisticated
sparing support such that hardware failure risk can be minimized by automatically regenerating the failed disk’s data on a
backup disk.
2
The software driver includes support for S.M.A.R.T. monitoring to predict suspect drives.
1.1.2
Data Performance
SATARAID5 can also increase storage throughput by combining the throughput of multiple drives into a single volume. RAID
levels 0, 5, and 10 support this ability. Furthermore, each volume can be tailored to provide the best performance for the data
contained on that disk.
1.1.3
Data Versatility
3
The driver also supports JBOD , Contiguous and Concatenated drives for applications which do not require increased security
or performance.
1.2
Ease of Use
The SATARAID5 Manager GUI offers an easy to use utility for creating and managing your storage. It also supports the latest
SATA enhancements including SATA-II Port Multiplier support, and up to 3Gbit/sec transfer rates on controllers that support
that speed. Creating and deleting volumes is also possible without requiring a restart of the operating system and rebuilds
never require the data to be taken off-line.
Drives can also be moved between controllers without losing the data.
1.3
Supported Operating Systems
The following operating systems are supported by the SATARAID5 driver. Check the Silicon Image website for additional
operating systems as they are supported.

2 An Introduction to RAID
2.1
RAID Volumes
RAID technology allows one or more disks to be combined into a logical volume which provides greater performance and/or
protection than standard disk drives. These volumes, also known as RAID Groups, appear like regular disk drives to the
operating system and can be partitioned, formatted and used just like any other normal disk. The complexity of the RAID is
hidden within the driver.
There are several different methods of combining disks, each with its own advantages and disadvantages. Each method is
referred to as a RAID “level” such as RAID 1, or RAID 5. The details of each level are summarized below and detailed in the
following sections.
RAID Level
0

Advantages
Excellent performance, low cost
Excellent data protection
Good data protection, good value
10
High performance, excellent data
protection.
Good performance, low cost
Same as single disk
Concatenation
JBOD
2.2
Disadvantages
No data protection
High cost
Some performance degradation for
writes.
High cost.
No data protection
Same as single disk
Segmenting Disks
For increased versatility, the SATARAID5 software allows individual disks to be divided into smaller segments which can then
be combined into different volumes. As an example, if a user has one set of data that must be protected at all costs, another
set of data which should be protected at reasonable cost and another set that doesn’t need any protection at all, the user can
divide three disks into sections as shown in Figure 1. The yellow regions define the high security volume, the greem section is
the middle security volume and the light blue shows the unprotected area.

RAID Levels
2.3.1
Disk Striping (RAID 0)
Striping is a performance-oriented, non-redundant data mapping technique. While Striping is discussed as a RAID Group type,
it is does not provide any fault tolerance. With modern SATA and ATA bus mastering technology, multiple I/O operations can
be performed in parallel, enhancing data throughput. Striping arrays use multiple disks to form a larger virtual disk. The figure
below illustrates a three-disk stripe set. Stripe one is written to disk one, stripe two to disk two, and so forth. RAID 0 sets can
be comprised of two, three, or four drives.
Stripe0
Stripe1
Stripe2
Stripe3
Stripe4
Stripe5
Stripe6
Stripe7
Stripe8
Stripe9
Stripe10
Stripe11
2.3.2
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 instantaneous protection from a single disk failure. If a read failure occurs on one drive, the system reads
the data from the other drive. RAID 1 sets are comprised of two drives. A third drive can be allocated as a spare in case one
of the drives in the set fails.
Block 0
Block 1
Block 0
Block 2
Block 1
Block 3
Block 2
Block 3
2.3.3
Disk Mirroring and Striping (RAID 10)
RAID 10 combines the features of both RAID 0 and RAID 1. Performance is provided through the use of Striping (RAID 0),
while adding the fault tolerance of Mirroring (RAID 1). The implementation of RAID 10 requires four drives. The drives are
assigned as two sets of striped pairs.
The data is written to RAID Group A, which is striped (RAID 0). This allows maximum speed. The data is then mirrored to
another RAID 0 striped set, which is Set B in the figure above. This provides data redundancy (RAID 1), and thus increased
data security.
Under certain circumstances, a RAID 10 set can sustain multiple simultaneous drive failures.
2.3.4
Parity RAID (RAID 5)
Parity or RAID 5 adds fault tolerance to Disk Striping by including parity information with the data. Parity RAID dedicates the
equivalent of one disk for storing parity stripes. The data and parity information is arranged on the disk array so that parity is
SATARAID5 User’s Manual

7
written to different disks. There are at least 3 members to a Parity RAID set. The following example illustrates how the parity is
rotated from disk to disk.
Parity RAID uses less capacity for protection and is the preferred method to reduce the cost per megabyte for larger
installations. Mirroring requires 100% increase in capacity to protect the data whereas the above example only requires a 50%
increase. The required capacity decreases as the number of disks in the group increases.
2.3.5
Concatenation
Concatenation combines multiple disks or segments of disks into a single large volume. It does not provide any data
protection or performance improvement but can be useful for utilizing left over space on disks. Concatenation allows the
segments which make up the volume to be of difference sizes.
2.3.6
JBOD (Just Bunch of Disks)
The JBOD is a virtual disk that can either be an entire disk drive or a segment of a single disk drive. For home edition, JBOD
function only supports one disk.
2.4
RAID Volume Status
A RAID Volume can be in any one of the following statuses.
Status
Meaning
Good
All disks are currently functioning Normal
Degraded
For RAID levels which contain some data protection, one or more disks have failed but the data is still
available via the RAID algorithms. The failed disk should be replaced as soon as possible.
Rebuilding
A failed disk drive has been replaced and the data is being regenerated on the replacement disk. When
complete, the RAID Group will return to Good status.
Resynchronizing An error has occurred which requires that the RAID algorithms be regenerated on this RAID Group.
When complete, the RAID Group will return to Good status.
Failed
One or more disks have failed and RAID algorithms can no longer regenerate the data. The minimum
number of failures required to reach this state depends on the RAID level

4 SATARAID5 Manager
4.1
Overview
The SATARAID5 Manager is the Graphical User Interface (GUI) which allows you to create and manage RAID volumes. The
Manager initially shows two windows as seen below.
The RAID Groups window identifies SATA host adapters and configured RAID groups. For systems with more than one
Silicon Image Host Bus Adapter installed, you can switch between cards by selecting the desired card in the RAID Groups
Window.
When a controller is selected, the RAID Groups currently defined on that controller are also shown in the RAID Groups
Window. Selecting a specific RAID Group will highlight the segments associated with that volume in the Device Configuration
Window.
The Device Configuration window identifies all physical drives and their partitions. If the adapter supports SATA-II Port
Multipliers, there may be more than one device ID per SATA channel.
Throughout the Manager, different colors are used to indicate the status of the components. The meaning of the colors are
Color
Green
Yellow
Red

4.2
Status
Good. The component and all subcomponents are okay.
Warning. This component or at least one subcomponent has become
degraded and requires service.
Failed. This component or at least one subcomponent has failed.
Unused.
Creating RAID Groups
To begin creating a new RAID Group, select “Create RAID Group” from the RAID Group menu or right click on a controller in
the RAID Groups window and select “Create RAID Group”. This will cause the Create RAID Group dialog to appear.

SATARAID5 User’s Manual
The fields are defined as follows:
RAID Group Label:
Provides an identifiable name for the RAID group. This field can be any ASCII string to help the
user identify this volume.
RAID Group:
Select a Group ID from the available ID list. The maximum number of RAID Groups per controller
is 8 so Group ID can be any number between 0 and 7 inclusive.
Configuration:
The configuration indicates which RAID level is to be used to configure these members. The
options are:
Contiguous (for virtual disk or JBOD)
Concatenated (for multiple concatenated segments)
Striped (for RAID 0)
Mirrored (for RAID 1)
Mirrored Striped (for RAID 10)
Parity RAID (for RAID 5)
Capacity:
This defines the total usable capacity of the RAID Group. Either select an entry from the pull down
list or manually enter the volume size in Gigabytes. Selecting MAX will create the largest RAID set
possible with the drive(s) selected.
Chunk Size:
Chunk size, also known as stripe size, is for advanced users who want to tune their box for the
greatest performance. In general, large stripe sizes are best for large files that are accessed
sequentially (e.g. media streaming files) whereas smaller sizes are better for randomly accessed
data like databases. This parameter is not used for Contiguous, Concatenated, Mirrored or JBOD
RAID levels.
Rebuild Priority:
Rebuild priority indicates how quickly the controller should rebuild data on a disk following a
hardware failure. A value of 1 is the lowest priority and will take the longest to rebuild. A value of
10 is the highest priority and will rebuild the fastest but may require more CPU resources which
could have some impact on the computer’s performance. This parameter is not used for
Contiguous, Concatenated, Striped or JBOD RAID levels.
Devices:
Select RAID member devices from the available device segment list. The minimum number of
disks is determined by the RAID level as shown in the following table.

Logical Drive Info
Create RAID Group is used to create a new legacy RAID Set or for allocating legacy spare drives.
Delete RAID Group is used to delete a legacy RAID Set or to deallocate a legacy spare drive.
Rebuild RAID 1 Set is used to initiate the rebuild of a RAID 1 set after, for example, a drive in the Group has been replaced.
Resolve Conflicts is used to automatically find the member drives of a RAID set which has been disrupted (physical drives
swapped around, for example) and restore the Set to proper operation.
Low Level Format allows a single drive to have its data completely wiped out. Drives assigned to Sets or allocated as spares
cannot be low level formatted.
Logical Drive Info shows the current configuration of each RAID set, allocated spare, and unallocated physical drive attached
to the SATA host adapter.
These operations are detailed in the pages that follow.

5.1
Creating RAID Groups
As previously discussed, the Silicon Image SATA host adapter supports RAID 0, 1, 5, 10, and JBOD configurations. The
selection of the RAID level to be used should be based upon factors including performance, data security, and number of
drives available. It is best to carefully consider the long-term role of the system and plan the data storage strategy
appropriately.
Silicon Image has made the creation of RAID sets very simple. They can be created either automatically or to allow the
greatest flexibility, manually.
1.
Select “Create RAID set”
2.
Choose a RAID 0 Striped, a RAID 1 Mirrored, a RAID 5 Parity, or a RAID 10 combination set.
3.
Select Automatically or Manually configuration of the RAID Set.
Copyright © 2004 Silicon Image Inc.
42
SATARAID5 User’s Manual
4.
If manual configuration is selected, the chunk size of Striped Sets can be selected. For Mirrored Sets, the Source and
Target drives can be selected.
5.
If auto configuration is selected, BIOS will select RAID member drives automatically and the chunk size of Striped Sets is
set to 64KB.
6.
Select RAID set size with ↑ and ↓ keys. See section 6.9 for explanation on selecting size.
7.
After the RAID set size is set, the message “Are You Sure?” will display before completing the configuration. Answer “N”
to abort the creation of the new RAID set, or “Y” to proceed with the RAID set creation.

5.2
RAID sets can be created in both BIOS and in the SATARAID5 GUI. If you have excess capacity left on your hard drives
after creating a RAID set in the BIOS, you can later go to the SATARAID5 GUI to create additional logical drives that
fully utilize the capacity on all your hard drives.
Creating Spare Drive
If there is a RAID 1 set, spare driver can be created. The spare drive can be allocated to the RAID 1 set in the event of a
failure of one of the drives in the RAID 1 set.
1.
To create a spare drive for RAID 1 set, Select “Create RAID set”
2.
Select “Spare Drive” and press Enter.
3.
Select spare drive from the physical drive list and press Enter.
4.
Select spare drive size with ↑ and ↓ keys. See section 6.9 for explanation on selecting size.
5.
After the spare drive size is set, the message “Are You Sure?” will display before completing the configuration. Answer
“N” to abort the creation of the spare drive, or “Y” to proceed with the spare drive creation.
5.3
Creating JBOD
Since BIOS no longer reports non-RAID drives to the system BIOS, if a non-RAID boot drive or data drive is desired, a JBOD
can be created so BIOS will report it to the system BIOS.
1.
To create a JBOD, Select ”Create RAID set”
2.
Select “JBOD” and press Enter.
3.
Select JBOD drive from the physical drive list and press Enter.
4.
Select JBOD size with ↑ and ↓ keys. See section 6.9 for explanation on selecting size.
5.
After the JBOD size is set, the message “Are You Sure?” will display before completing the configuration. Answer “N” to
abort the creation of the JBOD, or “Y” to proceed with the JBOD creation.
5.4
Deleting RAID Groups, Spare Drive, and JBOD
1.
To remove one or more RAID sets, spare drives, and JBODs, select “Delete RAID set”
2.
Select the desired item to delete from the logical drive list and press Enter.
3.
Press “Y” when asked, “Are You Sure?”
4.
The drives will be returned to the selection of logical drives from which a new RAID set can be created.

Resolving Conflicts
When a RAID set is created, the metadata written to the disk includes drive connection information including the channel on
the host adapter to which it is connected. 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 correct this, select “Resolve Conflict” and the correct metadata, including the
correct drive connection information; will automatically be written to the replacement disk.
1.
Select “Resolve Conflicts” and press Enter.
2.
Select the “Conflict” entry in the Logical Drive Status window and press Enter.
SATARAID5 User’s Manual
Copyright © 2004 Silicon Image Inc.
47
3.
Note that some conflict resolutions may result in the drive letter assignment changing; for example the RAID set may
have been drive D: but after the conflict resolution, it may become drive E. Be aware of this when performing a conflict
resolution. To maintain the same drive lettering, the SATA cables connected to the drives may need to be swapped, or in
the case of a SATA-based removable drive unit, the order of the drives within the chassis made need to be changed.
Press ‘Y’ to accept the change and resolve the conflict.
4.
The conflict will be resolved. The RAID Set will appear in the Logical Drive window.

Low Level Formatting
The Low Level Format menu selection allows the complete erasure of data on a hard drive. This is not an action, which
typically needs to be performed as formatting the drive under Windows is usually sufficient to prepare the drive for use.
5.8
Logical Drive Information
This menu item allows the display of the assignment of physical drives within a logical set (RAID set, RAID 1 spare, or
unassigned). It is a display-only function. Use the up and down arrow keys to scroll between the drives in the Logical Drive
Properties window. Press the ESC key when done viewing logical drive information.
5.9
Reserved Drive and Setting Size for RAID Set, Spare Drive, or JBOD
Once a physical drive has been used to create a RAID set, spare drive, or JBOD by BIOS utility, BIOS saves user selected set
or drive size in the reserved area of the physical drive. There is no way to remove the reserved area information even after the
SATARAID5 User’s Manual

49
user deletes the set or drive. For this reason, after a set or drive is deleted, BIOS recognizes the physical drive as a reserved
logical drive and it will not report the drive to the system BIOS.
When user selects to create a RAID set, spare drive, or JBOD, he or she has to select size for the set or drive. BIOS will set a
default size for it and user can use the ↑ and ↓ keys to change the size. If the physical drive has never been used to create a
set or drive by the BIOS before, the full size of the physical drive will be set as default size. Otherwise, BIOS will set default
size to the size it saved in the reserved area of the physical drive before.
If the user wants to increase the default size, BIOS will display a warning message in the help window and for user’s response
before changing the default size.

6 Allocating Partitions in Windows
After the RAID groups have been created either using SATARAID5 Manager or BIOS Menu Utility, the RAID group must have
a partition defined on it, then the RAID group must be formatted in preparation for use under Windows.
Windows XP, 2000, and Server 2003 use the Disk Management utility that is part of the Operating System. There are enough
nuances that make it important to follow the procedure specific to the Operating System.
6.1
Windows Server 2003 & XP & 2000
Before creating any partitions, RAID groups must first be created using the BIOS RAID Utility or the SATARAID5 GUI. Once
the sets have been created, allow the system to load Windows. Once Windows is running, open the Disk Management window
located at:
Control Panel> Administrative Tools> Computer Management> Storage> Disk Management
A window similar to the following should appear:
This window has three main sections:
1)
System listing of all formatted and available disks/RAID Groups.
2)
Report of physical connection of disks/RAID Groups.
3)
Report of partition status, disk letter, and volume name.
In the physical connection window, every disk should report as:
Basic
Disk Size (the actual available disk space will be reported here)
Online
SATARAID5 User’s Manual
Copyright © 2004 Silicon Image Inc.
51
Instead of “Basic,” a disk may also report as either “Unknown” or “Dynamic.” If the disk reports as “Unknown” right-click on the
disk icon and click “Write Signature.” A window will appear with the disk in question (all “Unknown” disks may appear in this
window). Make sure the box next to each disk is checked, and then click OK. The disk should now report as “Basic.”
If a disk reports as “Dynamic,” right-click on the icon of that disk, and click on “Revert to Basic Disk...” Within seconds the disk
should report as Basic.
6.1.1
Creating the Partitions
In the Report of physical connection of disks/RAID Groups section, the order in which the drives are displayed corresponds
directly to the order the Sets appear in the BIOS. Therefore, the first Unallocated Partition represents Set 1, and so on.
1.
In this example, there are two disks with unallocated partitions. Right-click on the partition of the first disk and click on
“Create Partition...”
2.
The “Create Partition Wizard” should appear. The first window is an introductory window to the Wizard. Click Next.
3.
The second window designates the partition type. Choose primary partition and click Next.
Copyright © 2004 Silicon Image Inc.
52
SATARAID5 User’s Manual
4.
The third window designates the partition size. Since this is a Striped RAID set utilizing 2 disk drives, the size of the
partition will be approximately twice the size of the smallest single disk drive. Click Next.
5.
The fourth window designates the drive letter of the partition. Change the drive letter if desired. Click Next.
SATARAID5 User’s Manual

6.
The next window allows the volume label to be set and selection of the type of formatting to take place upon the creation
of the partition. Make sure the Format this partition. . .” radio button is selected. Name the volume as desired
(suggestions are generic names such as STRIPED SET or something specific to use such as FINANCIAL, CRITICAL,
MISCELLANEOUS, etc.). It is recommended to use the default NTFS for the file system. Click Next.
7.
The last window is a summary window listing all of the selections made. After verifying that everything is correct, click
Finish.
SATARAID5 User’s Manual

55
The status of the newly created partition in the Disk Management window should change to Formatting and the percentage
complete will be displayed. Depending upon the size of the partition, the format process may take several minutes. When
complete, the status will change to “Healthy” and the name and drive letter will be updated. Once the disk reports Healthy, it
appears in the listing in System Listing section with all of its pertinent information as well.
Repeat the above procedure as needed for any other partitions. Close the Data Management window by clicking on the small
boxed “X” in the top right corner of the window. Click on the “My Computer” icon on the Desktop. The new drives will be visible
and properly named. The new disks are available for use.
