Glossary RAID 1 See mirror set (RAID 1). RAID 0/1 See stripe set of mirror sets (RAID 0/1). RAID 0/5 See stripe set of RAID 5 sets (RAID 0/5). RAID 5 set An array type that is similar to a stripe set in that it stripes data evenly across its respective drives in equal-sized chunks, except that it uses parity to provide redundancy. A RAID 5 set must be made up of at least three equal-sized partitions on different drives. You must have at least three partitions to permit the system to rebuild the data if one drive fails. As data is striped across the partitions, one chunk of each stripe is used for parity data. See also chunk; partition; parity. redundancy The capability of preventing data loss if a drive fails. Some array types give you this capability using one of two methods: two identical copies or parity. S SAF-TE Stands for SCSI Accessed Fault-Tolerant Enclosure. The SAF-TE specification is an open specification designed to provide a comprehensive standardized method to monitor and report status information on the condition of disk drives, power supplies, cooling systems, and other components used in high-availability LAN servers and storage subsystems. See also enclosure. SCSI ID The number assigned to each SCSI device attached to a SCSI channel. Also known as the target ID. See also channel; disk ID; enclosure ID. slot A receptacle in an enclosure for inserting and removing a SCSI device. Glossary-5
