6 RAID Configuration and Management Introduction to RAID Overview of RAID Redundant array of independent drives (RAID) is an array of multiple independent hard drives that can be accessed simultaneously, improving I/O (input/output) performance. The host computer recognizes the RAID array as a single storage unit or as multiple logical units. When a drive fails, RAID 1 and RAID 1+0 arrays can prevent data loss by reconstructing missing data from the remaining data drives. RAID Terminology IMPORTANT: Only RAID levels 0, 1, and 1+0 are supported by the Integrated ATA RAID Configuration Utility. RAID 0 (Stripe) RAID 0 is a RAID level that involves breaking up data into smaller blocks and then writing a block to each drive in the array (striping). RAID 0 does not provide any data redundancy, but does offer the best performance of any RAID level. HP ProLiant ML330 Generation 3 Server Setup and Installation Guide 6-1
