Glossary drive. The controller generates parity every time data is written to the array, and it is distributed in stripes across all the drives. RAID 10 Dual-level RAID type created by using two or more equal-sized RAID 1 arrays to create a RAID 0. Both read and write performance are improved due to array striping. However, the performance improvement costs additional storage space due to the mirroring of the arrays. RAID signature The area on each disk reserved for use by the RAID controller. RAID volume Concatenates two or more arrays of the same type. rebuild Background regeneration of redundant data on a RAID 1. reconfiguration Process of expanding an array or migrating an array from one RAID type to another; changing the stripe size of a RAID 0, or moving a logical device's segments to other disks. redundant The ability of an array to maintain operability when one or more hardware failures occur. RAID 1 is redundant. In the event of a drive failure, redundant arrays can be restored to normal operation by replacing the failed drive and rebuilding the array. rescan Process of updating the current screen to show all currently available resources. S segment Contiguous area of a physical drive that makes up some or all of an array. When the software creates an array, it automatically converts space into segments. Glossary-8
