1 Welcome Silicon Image’s SATARAID5 software provides Serial ATA RAID 0 (Striping) and RAID 1 (Mirroring) functionality to enhance the industry’s leading PCI-to-SATA host controller products. 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 while utilizing full disk capacity.
2 An Introduction to RAID RAID - Redundant Array of Independent Disks RAID technology manages multiple disk drives to enhance I/O performance and provide redundancy in order to withstand the failure of any individual member, without the loss of data. There are many different methods of implementation for RAID, with each having advantages and disadvantages.
Note: For users without a startup disk. Use an alternative system and insert the GIGABYTE motherboard driver CD-ROM. From the CD-ROM drive (example: D:) double-click the MENU.exe file in the BootDrv folder. A command prompt window will Figure 1 open similar to that in Figure 2.
4 JAVA 2 Runtime Environment Installation The Java 2 Runtime Environment is required for the SATARAID5 GUI. The Java 2 Runtime Installer and executable package must be downloaded from the Sun Microsystems website at http://java.sun.com/j2se/downloads.html. The computer must have an Internet connection set up before installation can proceed. Save the installer file to a known location, such as the My Documents folder.

Choose the Typical setup type and click Next. When the installation completes, click Finish. Restart the computer when prompted. SATARAID5 User’s Manual...
5 SATARAID5 GUI Installation Insert the motherboard driver CD into the computer’s CD-ROM drive. When the autorun window appears, click the SOFTWARE APPLICATIONS button at the left of the window. Find the Silicon Image SATA RAID Utility and install it. Click the Next button when the Welcome window appears.
Creating and Deleting Legacy RAID Groups with BIOS Utility Legacy RAID sets can be created and managed by either the BIOS utility or the SATARAID5 GUI. New RAID groups must be created and managed by the SATARAID5 GUI. See section 8 SATARAID5 GUI Overview for information on configuring RAID Groups using the SATARAID5 GUI.
Main Menu The Main Menu in the upper left corner is used to choose the operation to be performed. The selections are: Create RAID Group Delete RAID Group Rebuild RAID 1 Set Low Level Format 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.
6.1 Creating RAID Groups As previously discussed, the Silicon Image SATA host adapter supports RAID 0 and RAID 1 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.
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. If auto configuration is selected, BIOS will select RAID member drives automatically and the chunk size of Striped Sets is set to 64KB.
After the CONCATENATION drive(s) is set, the message “Are You Sure?” will display before completing the configuration. Answer “N” to abort the creation of the CONCATENATION, or “Y” to proceed with the CONCATENATION creation. 6.4 Deleting RAID Groups, Spare Drive, and Concatenation To remove one or more RAID sets, spare drives, and concatenations, select “Delete RAID set”...
6.5 Rebuild RAID 1 Set This menu selection is used to initiate the copying of data from an existing drive to a replacement drive that has been installed in a RAID 1 set after the failure of one of the members. Select “Rebuild RAID 1 set”...
6.6 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. 6.7 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).

When user selects to create a RAID set or spare drive, 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.
7 Allocating Partitions in Windows After the Raid groups have been created either using BIOS RAID utility or SATARAID5 GUI, 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.
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).

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. The fourth window designates the drive letter of the partition. Change the drive letter if desired. Click Next. SATARAID5 User’s Manual...
Page 21
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.).
Page 22
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.
