Appendix A Appendix B

Data Performance

SATARAID5 can increase storage throughput by combining the throughput of multiple drives into a single volume. RAID levels 0, 5, and 10 support this ability.

Data Versatility

The driver supports Just a Bunch of Disks (JBOD) and Concatenated drives for applications that do not require increased security or performance. The JBOD state may also be achieved with the drivers Pass-Thru feature. Pass-Thru allows access to a new hard disk or one without any SATARAID5 configuration.

Ease of Use

The SATARAID5 Manager GUI offers an easy-to-use utility to create and manage your storage. Creating and deleting volumes is possible without requiring a restart of the operating system. Rebuilds never require the data to be taken off-line. Note: A known problem with some versions of Microsoft Windows may cause an unnecessary Parity Rebuild operation following hibernation. To address this issue, please apply the patch available from Microsoft at http://support.microsoft.com/?kbid=902853
SATARAID5 Management Software User's Guide Page 2
Using the SATARAID5 Manager
This section explains how to use the SATARAID5 Manager graphical user interface (GUI) to create and manage RAID groups. Please install the SATARAID5 Manager software as explained in the SATARAID5 Quick Installation Guide for your computers operating system before you perform these tasks. Refer to Appendix A for information about managing the Flash BIOS of the RAID controller on a Windows system. Note: Be sure to download and install the latest Java Run-Time Environment for your system.
Launching the SATARAID5 Manager
The SATARAID5 Manager consists of a daemon and Java-based GUI applet. Depending on the operating system, the daemon runs as Windows Service or a script-launched background process responsible for monitoring of the local SATARAID5 driver.

Windows Systems

On a Windows system, the SATARAID5 Manager GUI shortcut is installed in the Windows Startup folder to be launched automatically whenever your system is rebooted. To manually start the SATARAID5 Manager, click the Start button, open the SATARAID5 Manager program group, and click on the SATARAID5 icon.

Color Status

Green Yellow Red Blue White Gray
Good. The component and all subcomponents are functioning correctly. Warning. The component, or at least one subcomponent, has failed or become unavailable and requires service. Failed. The component, or at least one subcomponent, has failed. Pass-Thru device. The component is valid, but it does not contain any RAID metadata, so it will function as an ordinary hard disk drive. A square with capacity shows an unallocated driver reserved for configuration into a RAID set. An empty square presents a free slot that will be filled by adding a hard disk drive to the system. Unused.
Note: Throughout this manual, the term right-click refers to using the secondary button on your mouse to perform the indicated operation. On a Windows or Linux system, use the mouse button that you have defined to be the right button (which by default is on the right side of the mouse, unless you have changed the primary and secondary buttons using Control Panel Mouse on Windows). On a Macintosh system, press and hold the COMMAND (Apple) button and click the mouse.
SATARAID5 Management Software User's Guide Page 4

Creating RAID Groups

Redundant Array of Independent Disks (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, known as RAID Groups, appear like regular disk drives to the operating system and can be partitioned, formatted and used just like any other disk. The RAID complexity is hidden within the driver. Note: The maximum allowable size of a RAID group that can be created by the SATARAID5 Manager is 144,115,188,075,855,872 bytes (which represents 248 bit addressability). However, some Linux platforms may limit the maximum size of a volume to 2TB, so the largest allowable size of a RAID group is 2,199,023,255,552 bytes.

RAID Levels

There are several 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 Advantages Disadvantages
RAID 0 RAID 1 RAID 5 RAID 10 Concatenated JBOD
High performance, low cost. Excellent data protection. Good data protection, good value. High performance, excellent data protection. Good performance, low cost, large volume size. Same as single disk.
No data protection. High cost. Performance degradation on writes. High cost. No data protection. Same as single disk.

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 include two, three, four or five drives. If the sizes of the disk segments are different, the smallest disk segment will limit the overall size of the RAID Group.
Stripe 0 Stripe 3 Stripe 6 Stripe 9 Stripe 1 Stripe 4 Stripe 7 Stripe 10 Stripe 2 Stripe 5 Stripe 8 Stripe 11
SATARAID5 Management Software User's Guide Page 5

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 typically comprised of two drives, and a third drive can be allocated as a spare in case one of the drives in the set fails. Additional drives can be configured as part of a mirrored set, but without much added benefit. If the sizes of the disk segments are different, the smallest disk segment will limit the overall size of the RAID Group.
Block 0 Block 1 Block 0 Block 1 Block 2 Block 3 Block 2 Block 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 mirrored pairs.

The data is written to RAID Group A, which is mirrored (RAID 1) and provides data redundancy. Alternating blocks of data are then striped across another RAID 1 mirrored set, shown as Set B in the figure above. This provides improved speed. Under certain circumstances, a RAID 10 set can sustain multiple simultaneous drive failures.

Parity RAID (RAID 5)

Parity RAID, 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 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 using three hard drives only requires a 50% increase. The additional required capacity decreases as the number of disks in the group increases (i.e., 33% for four drives or 25% for five drives).
SATARAID5 Management Software User's Guide Page 6
In exchange for low overhead necessary to implement protection, Parity RAID degrades performance for all write operations. The parity calculations for Parity RAID may result in write performance that is somewhat slower than the write performance to a single disk.

Concatenated

The Concatenated mode 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 leftover space on disks. Concatenation allows the segments that make up the volume to be of different sizes.
Just a Bunch of Disks (JBOD)
The JBOD is a virtual disk that can either be an entire disk drive or a segment of a single disk drive. JBOD is the Contiguous configuration option when creating RAID Groups (or sets) in the SATARAID5 Manager utility.

RAID Volume Status

A RAID volume can be in any one of the following statuses.

Status Meaning

Good Reduced Rebuilding Resynchronizing
All disks are currently functioning as normal. For RAID levels that provide 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 to avoid loss of data. 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. An error has occurred and requires that the RAID algorithms be regenerated on this RAID Group. When complete, the RAID Group will return to Good status. 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: RAID 0, Concatenated, JBOD/Contiguous: Single-disk failure. RAID 1, 5, 10: Two-disk failure.

SATARAID5 Management Software User's Guide Page 10
Note: Depending on the manufacturer and capacity of the hard drives that you are using, a small amount of the total disk capacity (less than the amount of one chunk size) may not be available, especially if you have selected one of the larger chunk sizes. 6. Refer to Chapter 4, Allocating Partitions for information about how to define partitions and volumes for the RAID Groups you created.
Disconnecting a RAID Group
For Windows system, some SATARAID5 device drivers provide ability to disconnect a RAID group while your computer system is running. To prevent data loss or other failures, you must follow the steps listed below when disconnecting a RAID group. 1) Click on the Eject icon (a small green arrow over a hardware image) in the System Notification Tray located in the lower right corner of your screen.
2) A message will appear listing all of the removable devices that the Eject icon controls. Click on the Safely remove <xxxxxxxx> SCSI Disk Device - Drive (X:) item in that list (where xxxxxx is the vendor and model name of the hard disk drive and X is the drive letter for the RAID group that you wish to disconnect). 3) When the message: Safe to Remove Hardware appears, you can safely disconnect the device from your computer. Note: If your host adapter driver software does not support this feature, the device should be disabled using the Device Manager or your system should be powered off before disconnecting the RAID Group.
For Macintosh systems, you must un-mount the RAID Group volume by dragging its hard drive icon to the trash before disconnecting it.

Legacy Support Menu

On Windows and Linux platforms, you can create and manage Legacy RAID sets and JBOD using the SATARAID5 GUI or the BIOS RAID utility. Previous RAID drivers that do not support RAID 5 functionality are known as Legacy drivers and are being replaced with the SATARAID5 software. Legacy RAID volumes are supported by the SATARAID5 software and have the following benefits: Legacy volumes can be used as boot devices. Legacy volumes can be created and managed by the BIOS menu during system boot. Legacy RAID 0 and 10 volumes support a stripe size of 4K.
Note: Legacy Support is not available on Macintosh platforms, and that menu item does not appear.

This menu option is disabled if new RAID groups exist. If enabled, this menu option displays a dialog box to create a legacy RAID group. Enter values for the following parameters.

RAID Group

Select a group ID from the available ID list. The maximum number of Legacy RAID Groups is limited to the number of hard drives that are connected to the RAID controller. Select one of: Striped (for RAID 0) Mirrored (for RAID 1) Mirrored Striped (for RAID 10) Parity RAID (for RAID 5) Select from a list of RAID group sizes. Options include sizes from 256 MB to 100 GB, plus MAX. Select a value from the available list to define the chunk size (stripe size) for performance tuning: 8, 16, 32, 64, 128 (KB). Mirrored (RAID 1) does not require a chunk size. Select a value to identify how quickly the controller should rebuild data on a disk after 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 might affect the computers performance. Striped (RAID 0) does not use this value. Select RAID member devices from the available device segment grid.

Managing Legacy RAID Groups with the BIOS RAID Utility
On Windows and Linux platforms with RAID controllers that have two or more ports, you can create and manage legacy RAID sets and JBOD using the BIOS RAID utility or the SATARAID5 GUI. You can create and manage new RAID groups only from the SATARAID5 Manager GUI.

Utility Overview

During the system boot-up process and before the Operating System loads, the following message appears for about 5 seconds. Press CTRL+S or the F4 key to enter the BIOS RAID utility.
If you are prompted whether to enable large disk support, respond Y so that you can create RAID groups on large disks that the BIOS RAID utility detected.

SATARAID5 Management Software User's Guide Page 36
Creating RAID Groups (Sets)
Select from RAID0, RAID1, and JBOD configurations when creating a new RAID group. Select a RAID level based on factors such as performance, data security, and number of drives available. Consider the longterm role of the system and plan the data storage strategy appropriately. 1. 2. Select Create RAID set from the Main Menu section of the RAID Configuration Utility screen. Select RAID0 (Striped) or RAID1 (Mirrored) and press Enter. Note: Procedures to create a JBOD configuration or a spare drive for a RAID1 set are documented separately. See Creating a JBOD Configuration and Creating a Spare Drive for a RAID1 Group.
SATARAID5 Management Software User's Guide Page 37
Select Auto configuration or Manual configuration of the RAID Set and press Enter. If you select Auto configuration, the BIOS RAID utility selects RAID member drives automatically and sets the chunk (stripe) size for striped sets to 64KB. If you select Manual configuration, select the chunk size for Striped Sets or select the Source and Target drives for mirrored sets.
SATARAID5 Management Software User's Guide Page 38
Select the size of the RAID set with the and keys and press Enter.
When the Are You Sure? confirmation prompt appears, respond Y to complete the RAID Set configuration. Note: If you have excess capacity left on the hard drives after creating a RAID set in the BIOS RAID utility, you can later go to the SATARAID5 Manager GUI to create additional logical drives that fully utilize the capacity of all hard drives.
SATARAID5 Management Software User's Guide Page 39
Creating a JBOD Configuration
The BIOS RAID utility does not report non-RAID drives to the system BIOS. If a non-RAID boot drive or data drive is desired, create a JBOD so the BIOS RAID utility will report the drive to the system BIOS. 1. 2. 3. 4. 5. Select Create RAID set from the Main Menu section of the RAID Configuration Utility screen. Select JBOD and press Enter. Select JBOD drive from the Physical Drive list and press Enter. Select the size of the JBOD drive with the and keys and press Enter. When the Are You Sure? confirmation prompt appears, respond Y to complete the JBOD configuration.

Some conflict resolutions may result in changing the drive letter assignment. For example, the RAID set may have been drive D, and after the conflict resolution, it becomes drive E. 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 may need to be changed. 3. When the Are You Sure? confirmation prompt appears, respond Y to resolve the conflict. The conflict is resolved and the RAID Set appears in the Logical Drive section.

Low Level Format

The Low Level Format menu option displays a pop-up menu with the following actions: Format 1st Part(ition), which removes the first Silicon Image partition on the disk. Secure Format, which formats the entire disk. Quick Format, which removes the first Silicon Image partition on the disk plus the last 1GB that contains the Silicon Image meta-data describing partitions.
SATARAID5 Management Software User's Guide Page 43
Note: The Low Level Format actions are typically not required, because formatting the drive under Windows is sufficient to prepare the drive for use.

Logical Drive Info

The Logical Drive Info menu option displays the assignment of physical drives within a logical set (RAID set, RAID 1 spare, or unassigned). Use the up and down arrow keys to scroll between the drives in the Logical Drive list. Press the ESC key when you are finished viewing logical drive information.
SATARAID5 Management Software User's Guide Page 44

Allocating Partitions

After you create RAID groups using the SATARAID5 Manager or BIOS Utility, define partitions on the RAID group and format them for use.
Define a Partition on MS-Windows
Use the Disk Management utility that is part of the XP, 2000, and Windows Server 2003 operating systems to define and format partitions on a Microsoft Windows host computer. 1. 2. From the Start button in the Windows taskbar, select Control Panel > Administrative Tools > Computer Management. Select Disk Management in the Storage section of the utility to display a list of available disks.
SATARAID5 Management Software User's Guide Page 45
The Disk Management utility has three main sections to the right of the navigation tree: System listing of all formatted and available disks/RAID Groups (labeled 1 in the image). Report of physical connections for disks/RAID Groups (labeled 2 in the image). Every disk should display Basic, a Disk Size value (available disk space is reported here), and Online. Instead of Basic, a disk may be marked Unknown, Dynamic, or Not Initialized. If a disk is marked Unknown, right-click the disk icon and select Write Signature. A window opens with the disk in question (all Unknown disks may appear in this window). Make sure the box next to each disk is checked and click OK. The disk should now be marked as a Basic disk. If a disk is marked Dynamic, right-click the disk icon, and select Revert to Basic Disk. Within seconds, the disk should be marked as a Basic disk. If a disk is marked Not Initialized, right-click the disk icon, and select Initialize Disk. An additional dialog box appears allowing you to select which disks to initialize. Uncheck the Config Disk item and click OK. Within seconds, the selected disk(s) should be marked as a Basic disk. Report of partition status, disk letter, and volume name (labeled 3 in the image). The order in which the drives are listed corresponds to the order the RAID sets appear in the BIOS. The first Unallocated Partition represents Set 1, and so on. In this example, there are two disks with unallocated partitions.

Right-click the partition of the first disk to allocate and select Create Partition from the pop-up menu.
Click Next to acknowledge the introductory window to the Create Partition Wizard.
Note: If an external storage enclosure (such as the SV2000) is connected to the external SATA ports of the RAID controller, one or more additional disk devices may appear with a name of Config Disk SCSI Disk Device and a red indicator to show that it is not available. This is normal behavior for Windows, and those disk items should be ignored.
SATARAID5 Management Software User's Guide Page 46
Select Primary partition and click Next.
Click Next to accept the designated partition size. Because this example is a Striped RAID set with two disk drives, the size of the partition is approximately twice the size of the smallest disk drive.
SATARAID5 Management Software User's Guide Page 47
Accept the default drive letter assigned to the partition or select a different drive letter if desired. Click Next.
Make sure the Format this partition with the following settings radio button is selected. Keep the default of NTFS for the file system and Default for the allocation unit size. Enter a meaningful volume label (name), such as STRIPED SET, FINANCIAL, CRITICAL, and so on. Click Next.
SATARAID5 Management Software User's Guide Page 48
Verify the selections are correct and click Finish.
The status of the newly created partition changes to Formatting and the percentage complete is displayed. Depending upon the size of the partition, the format process may take several minutes. When complete, the status changes to Healthy and the name and drive letter are updated. The partitioned disk appears in the System Listing section with all of its pertinent information as well.
10. Repeat this procedure to partition other disks.
SATARAID5 Management Software User's Guide Page 49
11. When you are finished, close the Disk Management utility by clicking the X in the top right corner of the window. The new disks are now available for use.
Define a Volume on Mac OS X
After using the SATARAID5 Manager to create one or more RAID Groups, you can use the Disk Utility to define and format volumes on a Mac OS X computer system. 1. If you have not previously launched the Disk Utility, click on the Finder icon in the task bar, then click on Applications from the navigation menu to open the Applications folder. In the Applications folder, click on Utilities to open the Utilities folder. In the Utilities folder, click and drag the Disk Utility icon to task bar. Click on the Disk Utility icon in the Task Bar. The following dialog appears:
In addition to your systems hard disk, the RAID Groups that you previously created appear in the list. Click on the RAID Group you wish to format. The following dialog appears:
Note: Do not click on the Config Drive item in that list.

SATARAID5 provides our highest commitment to data security through the use of RAID architecture to back up and protect data. RAID levels 1, 5, and 10 provide data security. SATARAID5 supports sophisticated sparing support so that hardware failure risk can be minimized by automatically regenerating the failed disks data on a backup disk. The software driver includes support for Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) to predict disk failures. Drives can be moved between controllers without losing data.

Data Performance

SATARAID5 can increase storage throughput by combining the throughput of multiple drives into a single volume. RAID levels 0, 5, and 10 support this ability.

Data Versatility

The driver supports Just a Bunch of Disks (JBOD) and Concatenated drives for applications that do not require increased security or performance. The JBOD state may also be achieved with the drivers Pass-Thru feature. Pass-Thru allows access to a new hard disk or one without any SATARAID5 configuration.

Ease of Use

The SATARAID5 Manager GUI offers an easy-to-use utility to create and manage your storage. Creating and deleting volumes is possible without requiring a restart of the operating system. Rebuilds never require the data to be taken off-line. Note: A known problem with some versions of Microsoft Windows may cause an unnecessary Parity Rebuild operation following hibernation. To address this issue, please apply the patch available from Microsoft at http://support.microsoft.com/?kbid=902853

Using the SATARAID5 Manager
This section explains how to use the SATARAID5 Manager graphical user interface (GUI) to create and manage RAID groups. Please install the SATARAID5 Manager software as explained in the SATARAID5 Quick Installation Guide for your computers operating system before you perform these tasks. Refer to Appendix A for information about managing the Flash BIOS of the RAID controller on a Windows system. Note: Be sure to download and install the latest Java Run-Time Environment for your system.
Launching the SATARAID5 Manager
The SATARAID5 Manager consists of a daemon and Java-based GUI applet. Depending on the operating system, the daemon runs as Windows Service or a script-launched background process responsible for monitoring of the local SATARAID5 driver.

Windows Systems

On a Windows system, the SATARAID5 Manager GUI shortcut is installed in the Windows Startup folder to be launched automatically whenever your system is rebooted. To manually start the SATARAID5 Manager, click the Start button, open the SATARAID5 Manager program group, and click on the SATARAID5 icon.

Macintosh Systems

On a Macintosh system, the SATARAID5 Manager software is installed into the Applications / Utilities / Silicon Image / SATARAID5 folder. You can launch it by navigating to that folder and double-clicking on the icon for the SATARaid5.jar file.

Linux Systems

On a Linux system the SATARAID5 Manager and daemon can be installed into any subdirectory. Before launching the SATARAID5 Manager, the driver must be installed and the daemon must be running in background. If you are using a bootable version of the SATARAID5 driver, it is already included in your Linux kernel. If you are not using a bootable version of the SATARAID5 driver, you must manually load the driver by typing the following command:
insmod si3XXXr5.ko (where 3XXX refers to your specific SATA controller chip)
Then, the daemon must be started. If the daemon has been incorporated into the startup scripts (typically included within the /etc/rc directory structure, it will start automatically when you boot your system. Otherwise, you must manually start the daemon in a background mode by typing the following command:
./SATARaid5ConfigServer &
Finally, you can launch the SATARAID Manager by typing the following command:
java jar SATARaid5Manager
Note: The SATARAID5 Manager uses TCP port number 4242 for sending commands to the daemon and obtaining status. If a firewall is active on your system, be sure to enable access to that port number before launching the SATARAID5 Manager.
SATARAID5 Management Software User's Guide Page 3
When you start the SATARAID5 Manager GUI, the following divided window appears.
Note: All of the SATARAID5 Manager screen illustrations are shown for Microsoft Windows. The outer frame and buttons may appear slightly different on other operating system platforms. The number of channels shown in this screen will vary according to the type of RAID controller that is installed in your system. The Legacy Support menu item is not available on Macintosh systems. The left RAID Groups window identifies SATA host adapters and configured RAID groups. If more than one Silicon Image Host Bus Adapter is installed, you can switch between them by selecting any controller. This also displays the RAID Groups currently defined for each controller window. Select a RAID Group to display the segments associated with that volume in the Device Configuration window on the right. The Device Configuration window identifies all physical drives and their partitions. If the controller supports SATA-II Port Multipliers, there may be more than one device ID per SATA channel. Throughout the Manager, different colors indicate the status of components as follows.

Color Status

Green Yellow Red Blue White Gray
Good. The component and all subcomponents are functioning correctly. Warning. The component, or at least one subcomponent, has failed or become unavailable and requires service. Failed. The component, or at least one subcomponent, has failed. Pass-Thru device. The component is valid, but it does not contain any RAID metadata, so it will function as an ordinary hard disk drive. A square with capacity shows an unallocated driver reserved for configuration into a RAID set. An empty square presents a free slot that will be filled by adding a hard disk drive to the system. Unused.
Note: Throughout this manual, the term right-click refers to using the secondary button on your mouse to perform the indicated operation. On a Windows or Linux system, use the mouse button that you have defined to be the right button (which by default is on the right side of the mouse, unless you have changed the primary and secondary buttons using Control Panel Mouse on Windows). On a Macintosh system, press and hold the COMMAND (Apple) button and click the mouse.
SATARAID5 Management Software User's Guide Page 4

Creating RAID Groups

Redundant Array of Independent Disks (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, known as RAID Groups, appear like regular disk drives to the operating system and can be partitioned, formatted and used just like any other disk. The RAID complexity is hidden within the driver. Note: The maximum allowable size of a RAID group that can be created by the SATARAID5 Manager is 144,115,188,075,855,872 bytes (which represents 248 bit addressability). However, some Linux platforms may limit the maximum size of a volume to 2TB, so the largest allowable size of a RAID group is 2,199,023,255,552 bytes.

RAID Levels

There are several 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.

Definition

Rebuild Priority
Select a value to identify how quickly the controller should rebuild data on a disk after 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 might affect the computers performance. This parameter is not used for Contiguous (JBOD), Concatenated, and Striped configurations. Click the radio button to toggle the state of the Check Pointing feature. When Check Pointing is enabled, restoring data is very fast after an unexpected power loss, although normal performance may be slightly reduced. When Check Pointing is disabled, normal performance is improved, but restores can take a long time to complete. This selection is only available when the selected RAID configuration is Mirrored, Mirrored Striped or Parity RAID, and the Advanced RAID Features checkbox in the Configuration/Advanced Options dialog box is checked. Click the radio button to toggle the state of rebuild ability without taking the volume off-line. This selection is only available when the selected RAID configuration is Parity RAID and the Advanced RAID Features checkbox in the Configuration/Advanced Options dialog box is checked. Select the RAID member devices from the available device segment grid. Up to five members can be selected for Contiguous, Concatenated, Mirrored, Striped or Parity RAID modes (although Mirrored RAID Groups will typically contain only two members). Exactly four members must be selected for Mirrored Striped mode. Pass-Thru devices will appear with a highlighted background color.

Legacy Support Menu

On Windows and Linux platforms, you can create and manage Legacy RAID sets and JBOD using the SATARAID5 GUI or the BIOS RAID utility. Previous RAID drivers that do not support RAID 5 functionality are known as Legacy drivers and are being replaced with the SATARAID5 software. Legacy RAID volumes are supported by the SATARAID5 software and have the following benefits: Legacy volumes can be used as boot devices. Legacy volumes can be created and managed by the BIOS menu during system boot. Legacy RAID 0 and 10 volumes support a stripe size of 4K.

This menu option displays a dialog box to create a legacy spare drive. This option is disabled if new RAID groups exist.

Managing Legacy RAID Groups with the BIOS RAID Utility
On Windows and Linux platforms with RAID controllers that have two or more ports, you can create and manage legacy RAID sets and JBOD using the BIOS RAID utility or the SATARAID5 GUI. You can create and manage new RAID groups only from the SATARAID5 Manager GUI.

Utility Overview

During the system boot-up process and before the Operating System loads, the following message appears for about 5 seconds. Press CTRL+S or the F4 key to enter the BIOS RAID utility.
If you are prompted whether to enable large disk support, respond Y so that you can create RAID groups on large disks that the BIOS RAID utility detected.
SATARAID5 Management Software User's Guide Page 34
The RAID Configuration Utility screen is divided into four main sections and a command line.
The Main Menu section in the upper left lists actions to be performed. Select: Create RAID Group to create a new legacy RAID Set or allocate legacy spare drives. Delete RAID Group to delete a legacy RAID Set or de-allocate a legacy spare drive. Rebuild RAID 1 Set to initiate the rebuild of a RAID 1 set after replacing a drive in the Group. Resolve Conflicts to find the member drives of a disrupted RAID set and restore the Set to proper operation. Do this after moving physical drives. Low Level Format to wipe the data from a single drive. Do not format drives assigned to Sets or allocated as spares. Logical Drive Info to show the current configuration of each RAID set, allocated spare, and unallocated physical drive attached to the SATA host adapter. The Help section in the upper right displays context-sensitive help and status messages. The Physical Drive section in the lower left displays the model number and capacities of the drives physically attached to the SATA host adapter. The Logical Drive section in the lower right displays all logical drives connected to the controller. RAID sets and JBOD drives reported to the system BIOS are listed at the top of this section. Spare drives, reserved drives, conflict drives, and invalid drives not reported to the system BIOS are listed at the bottom of this section. The Command Line at the bottom of the screen lists the currently active command keys. Use: Up and Down arrows to select a menu option or action. ESC to go to the previous menu. Enter to select the highlighted choice. Ctrl-E to exit the utility. Other keys may be active depending upon the currently selected action.

SATARAID5 Management Software User's Guide Page 35
Reserved Logical Drives and RAID Set Sizes
When you create a RAID set, spare drive, or JBOD on a physical drive, the BIOS RAID utility saves metadata for the configuration in a reserved area of the physical drive. That metadata is not deleted when a RAID set or drive is deleted. After a set or drive is deleted, the BIOS RAID utility recognizes the physical drive as a reserved logical drive and does not report the drive to the system BIOS. When creating a RAID set, spare drive, or JBOD, one creation parameter is the size of the set or drive. You can accept the default size or you can use the and keys to change the size. If the physical drive has not yet been used to create a RAID set or drive, the BIOS RAID utility shows the full size of the physical drive as the default size. If the physical drive has previously been used, the utility shows the size that was saved in the reserved area of the physical drive.
When you increase the default size (using the key), the utility displays a warning message in the Help section of the RAID Configuration Utility screen and waits for you to confirm the size increase before changing the default size.
SATARAID5 Management Software User's Guide Page 36
Creating RAID Groups (Sets)
Select from RAID0, RAID1, and JBOD configurations when creating a new RAID group. Select a RAID level based on factors such as performance, data security, and number of drives available. Consider the longterm role of the system and plan the data storage strategy appropriately. 1. 2. Select Create RAID set from the Main Menu section of the RAID Configuration Utility screen. Select RAID0 (Striped) or RAID1 (Mirrored) and press Enter. Note: Procedures to create a JBOD configuration or a spare drive for a RAID1 set are documented separately. See Creating a JBOD Configuration and Creating a Spare Drive for a RAID1 Group.
SATARAID5 Management Software User's Guide Page 37
Select Auto configuration or Manual configuration of the RAID Set and press Enter. If you select Auto configuration, the BIOS RAID utility selects RAID member drives automatically and sets the chunk (stripe) size for striped sets to 64KB. If you select Manual configuration, select the chunk size for Striped Sets or select the Source and Target drives for mirrored sets.
SATARAID5 Management Software User's Guide Page 38
Select the size of the RAID set with the and keys and press Enter.
When the Are You Sure? confirmation prompt appears, respond Y to complete the RAID Set configuration. Note: If you have excess capacity left on the hard drives after creating a RAID set in the BIOS RAID utility, you can later go to the SATARAID5 Manager GUI to create additional logical drives that fully utilize the capacity of all hard drives.

SATARAID5 Management Software User's Guide Page 46
Select Primary partition and click Next.
Click Next to accept the designated partition size. Because this example is a Striped RAID set with two disk drives, the size of the partition is approximately twice the size of the smallest disk drive.
SATARAID5 Management Software User's Guide Page 47
Accept the default drive letter assigned to the partition or select a different drive letter if desired. Click Next.
Make sure the Format this partition with the following settings radio button is selected. Keep the default of NTFS for the file system and Default for the allocation unit size. Enter a meaningful volume label (name), such as STRIPED SET, FINANCIAL, CRITICAL, and so on. Click Next.
SATARAID5 Management Software User's Guide Page 48
Verify the selections are correct and click Finish.
The status of the newly created partition changes to Formatting and the percentage complete is displayed. Depending upon the size of the partition, the format process may take several minutes. When complete, the status changes to Healthy and the name and drive letter are updated. The partitioned disk appears in the System Listing section with all of its pertinent information as well.
10. Repeat this procedure to partition other disks.

When you are finished creating volumes, close the Disk Utility.
Define a Volume/Partition on Linux
Reload the SATARAID5 driver to show the newly created SATARAID5 volume. The SATARAID5 driver will show the resulting volume as a block device with prefix sd, /dev/sdx (where x is a, b, c, etc.). You can then use the fdisk command to partition the volume and the mkfs command to format the partitions and create a file system on each partition. You can then mount the files system as required. Note: If an external storage enclosure (such as the SV2000) is connected to the external SATA ports of the RAID controller, one or more additional disk devices may appear with a name of Config Disk SCSI Disk Device. This is normal behavior, and those disk items should be ignored.
SATARAID5 Management Software User's Guide Page 52
Appendix A Managing the BIOS
When the SATARAID5 driver software is installed on a Windows system, a Control Panel applet is also installed that allows you to update and view information about the RAID controller hardware and its Flash BIOS. You can access the Flash BIOS information using either of the methods described below. Third-party motherboard and host bus adapter manufacturers provide product-level qualification. Before you upgrade, please verify support for BIOS or driver updates with the product vendor or manufacturer.

Hosted Boot Device

The SATARAID5 controllers BIOS provides boot-up support and a configuration interface. To boot from the SATARAID5 BIOS hosted logical drive, follow system-specific steps to enter the system BIOS and specify the SATARAID5 BIOS hosted logical drive within the boot order. 1. As the system starts up, push the necessary key to enter system BIOS setup.
Using the system BIOS menus for navigation, select the Boot screen.
Ensure the SATARAID5 BIOS hosted logical drives appears within the boot list.
For physical and logical drives, the SATARAID5 BIOS defines a drive model number to include a device model number containing the PCI bus number, device function number, and device number. The SATARAID5 BIOS further describes a logical drive with the SiI label and the selected RAID mode.
PCI bus number : device function number device number SiI RAID mode Property Description
PCI bus number Device function number Device number RAID mode
The PCI bus number identifies the SATARAID5 controller location within the system. The function number for SATARAID5 controllers will default to 0. The device number identifies the device ID of the SATARAID5 controller on the previously noted PCI bus. The RAID mode reflects the RAID set level.
