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.
