Resumen del manual
In theory, any SCSI device can be plugged into any SCSI controller. spare A disk drive that you designate as a replacement disk drive as part of the spare pool. If a disk drive in a redundant array fails, the controller looks for a spare disk drive on which to rebuild the data of the failed disk drive. spare pool One or more disk drives that you designate as replacements for any arrays on a controller. stand-alone Stand-alone configuration refers to a storage system in which the controller operates autonomously. Glossary-10 Glossary storage area network (SAN) SAN is a dedicated network for storage data traffic that links one or more servers to one or more storage systems. Each storage system could be RAID, tape backup, tape library, CD-ROM library, or JBOD. SANs operate with both SCSI and networking (IP) protocols. Servers and workstations use the Fibre Channel (FC) network for shared data access to the same storage device or system. Legacy SCSI systems are interfaced using an FC-to-SCSI bridge. storage system A storage system is when the RAID controller resides outside of the host system enclosure. The storage system is controlled from the host system using Storage Manager Pro. Since the controller is accessed using standard SCSI protocols, the need for specific operating system drivers is eliminated. Some external RAID controllers can be configured with single or dual host channels and can support either stand-alone mode, or as an active-active failover pair. See also active-active; stand-alone. stripe set (RAID 0) An array type that is made up of two or more drives. The stripe set distributes, or stripes, data evenly across its respective disk drives in equal-sized sections called chunks. See also chunk; partition. stripe set of mirror sets (RAID 0/1) An array type that is made up of two or more equal-sized mirror sets. The data in a stripe set of mirror sets is redundant. See also mirror set (RAID 1); multilevel array. stripe set of RAID 5 sets (RAID 0/5) An array type that is made up of two or more equal-sized RAID 5 sets. The data in a stripe set of RAID 5 sets is redundant. See also RAID 5 set; multilevel array. stripe size Amount of data written to one partition before the controller moves to the next partition in a stripe set. T target A target is a device (peripheral) that responds to an operation requested by an initiator (host system). See also initiator. Glossary-11 Adaptec Storage Manager Pro for DuraStor User’s Guide target ID See SCSI ID. termination Termination (also known as a terminator block) refers to the electrical connection at each end of a SCSI bus. The function of a terminator block is to provide for a proper electrical transmission of the data across the cable. SCSI buses require that a terminator be placed on the output SCSI connector on the last SCSI peripheral. Data errors may occur in a SCSI bus that is not terminated. topology A network topo...
