Appendix VT8237RAID.p65 1 2006/12/18, 上午 09:46 M S-7255 M ainboard Introduction This section gives a brief introduction on the RAID-related background knowledge and a brief introduction on VIA SATA RAID Host Controller. For users wishing to install their VIA SATA RAID driver and RAID software, proceed to Driver and RAID Software Installation section. RAID Basics RAID (Redundant Array of Independent Disks) is a method of combining two or more hard disk drives into one logical unit. The advantage of an Array is to provide better performance or data fault tolerance. Fault tolerance is achieved through data redundant operation, where if one drives fails, a mirrored copy of the data can be found on another drive. This can prevent data loss if the operating system fails or hangs. The individual disk drives in an array are called “members”. The configuration information of each member is recorded in the “reserved sector” that identifies the drive as a member. All disk members in a formed disk array are recognized as a single physical drive to the operating system. Hard disk drives can be combined together through a few different methods. The different methods are referred to as different RAID levels. Different RAID levels represent different performance levels, security levels and implementation costs. The RAID levels which the VIA VT8237A / VT8237S SATA RAID Host Controller supports are RAID 0 and RAID 1. The table below briefly introduced these RAID levels. Capacity RAID Level No. of Drives RAID 0 2 Smallest size * 2 (Striping) RAID 1 2 Smallest size (Mirroring) Benefits Highest performance without data protection Data protection RAID 0 (Striping) RAID 0 reads and writes sectors of data interleaved between multiple drives. If any disk member fails, it affects the entire array. The disk array data capacity is equal to the number of drive members times the capacity of the smallest member. The striping block size can be set from 4KB to 64KB. RAID 0 does not support fault tolerance. RAID 1 (Mirroring) RAID 1 writes duplicate data onto a pair of drives and reads both sets of data in parallel. If one of the mirrored drives suffers a mechanical failure or does not respond, the remaining drive will continue to function. Due to redundancy, the drive capacity of the array is the capacity of the smallest drive. Under a RAID 1 setup, an extra drive called the .spare drive. can be attached. Such a drive will be activated to replace a failed drive that is part of a mirrored array. Due to the fault tolerance, if any RAID 1 drive fails, data access will not be affected as long as there are other working drives in the array.

Important The “Channel”, “Drive Name”, “Mode” and “Size (GB)” in the following example might be different from your system. Select Array Mode and press , a list of array modes will appear. Highlight the target array mode that you want to create, and press to confirm the selection. If RAID 1 is selected, an option list will popup and enable the users to select Create and duplicate which allows BIOS copy the data from the source to the mirroring drive. A-4 Appendix VT8237RAID.p65 4 2006/12/18, 上午 09:46 VIA VT8237A / VT8237S SATA RAID Introduction After array mode is selected, there are two methods to create a disk array. One method is “Auto Setup” and the other one is “Select Disk Drives”. Auto Setup allows BIOS to select the disk drives and create arrays automatically, but it does not duplicate the mirroring drives even if the user selected Create and duplicate for RAID 1. It is recommended all disk drives are new ones when wanting to create an array. Select Disk Drives lets the user select the array drives by their requirements.
