Serial ATA RAID Quick User’s Guide Introduction The SiS180 SATA controller is a hybrid solution that combines two independent SATA ports and one Ultra ATA port for support of up to two Serial ATA (Serial ATA RAID) and two Ultra ATA (Ultra ATA RAID) drives. However the South Bridge SiS964 SATA controller only support two Serial ATA on two independent ports. Specifications are as follows: Serial ATA Interface Serial ATA (SATA) is the latest generation of the ATA interface. SATA hard drives deliver blistering transfer speeds of up to 150MB/sec. Serial ATA uses long, thin cables, making it easier to connect your drive and improving the airflow inside your PC. ♦ Supports 150 MB/s transfers with CRC error checking ♦ Large LBA support for drives over 137 GB ♦ Data handling optimizations including tagged command queuing, elevator seek and packet chain command Ultra ATA Interface ♦ Standard ATA/IDE interface ♦ Supports Ultra ATA/133, Ultra ATA/100, and Ultra ATA/66 drives ♦ Supports CRC error checking for Ultra ATA drives ♦ Separate timing control for two devices attached to one ATA channel Serial/Ultra ATA RAID Interfaces The Serial/Ultra ATA RAID is designed to provide a cost-effective, high performance RAID solution that adds performance and/or reliability to PC desktops and/or servers using Serial ATA/150, Ultra ATA/133, Ultra ATA/100, Ultra ATA/66 hard disks. Serial/Ultra ATA RAID function supports striping (RAID 0), mirroring (RAID 1), striping + mirroring (RAID 0+1) and span (JBOD). Please note that the function supports hard disk drives only and the South Bridge SiS964 SATA controller don’t support Striping + mirroring (Raid 0+1). With striping, identical drives can read and write data in parallel to increase performance. Mirroring increases read performance through load balancing and elevator sorting while creating a complete backup of your files. Span would increase the logic hard disk space. Serial/Ultra ATA RAID striped arrays can double the sustained data transfer rate of Serial ATA/150 and Ultra ATA/133 drives. Serial/Ultra ATA RAID fully 1

Serial ATA RAID Quick User’s Guide supports Serial ATA/150 and Ultra ATA/133 specification of up to 150MB/sec per drive, depending on individual drive specifications. The technology also offers fault tolerant, data redundancy for entry-level network file servers or simply for desktop PC users wanting to continually protect valuable data on their PC. The Serial/Ultra ATA RAID offers RAID 1 mirroring (for two drives) to protect data. Should a drive that is part of a mirrored array fail, Serial/Ultra ATA RAID technology uses the mirrored drive (which contains identical data) to assume all data handling. When a new replacement drive is later installed, Serial/Ultra ATA RAID rebuilds data to the new drive from the mirrored drive to restore fault tolerance. Features The SiS180 controller support two Serial ATA (Serial ATA RAID) and two Ultra ATA (Ultra ATA RAID) drives. The South Bridge SiS964 SATA controller only support two Serial ATA (Serial ATA RAID) drivers. Support RAID function: RAID 0, RAID 1, JBOD and RAID 0+1. (RAID 0+1 function can be used by SiS180 controller with all hard drivers on it.) Support bootable disk except for RAID 0+1. Windows-based SiS RAID Utility software tool (only support Windows XP and 2000). BIOS RAID Setting Utility Support operating Systems Microsoft Windows 98 Second Edition 2

Serial ATA RAID Quick User’s Guide Step 0. What is RAID Know How This section will give you an overview about the RAID system and introduce the basic background and glossary which you need to know before using “SiS RAID Controller Application”. 1. RAID: (Redundant Array of Independent Disk Drives) use jointly several hard drives to increase data transfer rates and data security. It depends on the number of drives present and RAID function you select to fulfill the security or performance purposes or both. 2. RAID 0: Also known as “Stripping”. All of the data are distributed evenly to all of the existing drives. You gain benefits on performance because the data transfer rate is multiplied by the number of drives. However, RAID 0 has high risks of data security. All of the stored data will be lost if even any one drive in the RAID set crashes. 3. RAID 1: Also known as “Mirroring”. Two hard drives are required. The goal of RAID 0 is to ensure data security. Data is written to two or more drives synchronously. That is, 100% duplication of data from one drive to another. 4. RAID 0+1: Also known as “StripeMirror”. At least four hard drivers are required. RAID 0+1 is a combination of RAID 0 and RAID 1. Data is striped into two drives then mirrored. It provides high performance and high data protection. This is a costly solution as RAID 1 because the two mirrored drives represent an expensive insurance 5. JBOD: (Just a Bunch of Drives). Also known as “Spanning”. Two or more hard drives are required. Several hard disk types configured as a single hard disk. The hard drives are simply hooked up in series. This expands the capacity of your drive and results in a useable total capacity. However, JBOD will not increase any performance or data security. Performance hints and recommend setting For the best performance and reliability, please read suggestions. 1. In Serial ATA port, use Native Serial ATA drives. Parallel ATA to Serial ATA converter board is NOT suggested. In Parallel ATA port, use ATA 66/100/133 hard drives the following 2. 3. Use the same model hard drives. 4. If you have only two Serial ATA drives, the auto-configure function will assign each on a different channel as a master drive. Using only two Parallel ATA drives to create a RAID array is NOT suggested. It might decrease performance. 4
