7030 ATX Mainboard Introduction System Requirement Operating System Support NVRAID supports the following operating systems: Windows XP Home Edition Windows XP Professional Edition Windows 2000 Professional RAID Arrays NVRAID supports the following types of RAID arrays described in this section: RAID 0: RAID 0 defines a disk striping scheme that improves the disk read and write times for many applications. RAID 1: RAID 1 defines techniques for mirroring data. RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1 arrays. Spanning (JBOD): JBOD provides a method for combining drives of different s i z e s into one large disk. Summary of RAID Configurations Array RAID 0 RAID 1 RAID 0+1 JBOD Uses Non-critical data requiring high performance. Small databases or any other small capacity environment requiring fault tolerance. Critical data requiring high performance. Combining odd size drives into one big drive Advantages Drawbacks High data throughput. No fault tolerance. # Hard Disks m ultiple 100% data redundancy. Requires 2 drives for 2 the storage space of 1 drive. Optimized for both 100% data redundancy and performance. Allows spare disks. Combines and uses the capacity of odd size drives. Requires 2 drives for 4+ the storage space of 1 drive-the same as RAID level 1. Decreases performance because of the difficulty in using drives concurrently or to optimize drives for different uses. Multiple Fault Tolerance None Yes Yes No MSI Reminds You... Please note that users cannot install OS, either WinME or Win98, in their SATA hard drive. Under these two OSs, SATA can only be used as a normal storage device. 5-2
