Chapter 7: Technology Background This chapter covers the following topics: • Introduction to RAID (below) • Choosing a RAID Level (page 242) • Choosing Stripe Size (page 245) • Choosing Sector Size (page 245) • Cache Policy (page 246) • Cache Mirroring (page 248) • LUN Affinity (page 249) • Capacity Coercion (page 250) • Initialization (page 251) • Hot Spare Drive(s) (page 251) • Partition and Format the Logical Drive (page 252) • RAID Level Migration (page 252) • Media Patrol (page 255) • Predictive Data Migration (PDM) (page 256) • Transition (page 257) Introduction to RAID RAID (Redundant Array of Independent Disks) allows multiple hard drives to be combined together in a disk array. Then all or a portion of the disk array is formed into a logical drive. The operating system sees the logical drive as a single storage device, and treats it as such. The RAID software and/or controller handle all of the individual drives on its own. The benefits of a RAID can include: • Higher data transfer rates for increased server performance • Increased overall storage capacity for a single drive designation (such as, C, D, E, etc.) • Data redundancy/fault tolerance for ensuring continuous system operation in the event of a hard drive failure Different types of disk arrays use different organizational models and have varying benefits. Also see “Choosing a RAID Level” on page 242. The following outline breaks down the properties for each type of RAID disk array: 231
