MCP6P-M2 CHAPTER 4: RAID FUNCTIONS 4.1 O PERAT ION SYST EM z Supports Windows XP Home/Prof essional Edition, and Windows 2000 Prof essional. 4.2 RAID ARRAYS RAID supports the following types of RAID arrays: RAID 0: RAID 0 defines a disk striping scheme that improves 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. RAID 5: RAID 5 provides fault tolerance and better utilization of disk capacity. 4.3 HOW RAID 0: RAID WORKS The controller " stripes" data across multiple drives in a RAID 0 array system. It breaks up a large file into smaller blocks and performs disk reads and writes across multiple drives in parallel. The size of each block is determined by the stripe size parameter, which you set during the creation of the RAID set based on the system environment. This technique reduces overall disk access time and offers high bandwidth. Features and Benefits Drives: Minimum 1, and maximum is up to 6 or 8. Depending on the platf orm. Uses: Intended for non-critical data requiring high data throughput, or any env ironment that does not require f ault tolerance. Benefits: prov ides increased data throughput, especially f or large files. No capacity loss penalty f or parity. Drawbacks: Does not deliver any fault tolerance. If any drive in the array f ails, all data is lost. Fault Tolerance: No. Blo ck 1 Bl ock 3 Bl ock 5 Block 2 Bl ock 4 Bl ock 6 21
