Glossary
S.M.A.R.T
Stands for Self-Monitoring Analysis and Reporting Technology.
Hard drives that support this technology continually analyze
their performance and generate an alert if they determine that
the disk is likely to fail in the next few hours.
spare pool
A pool of multiple disks which automatically replace failed
disks on any array on the controller.
stand-alone disk
A disk that is not part of an array.
stripe set
A container made up of two or more equal-sized partitions that
reside on different disks. The stripe set distributes, or stripes,
data evenly across its respective disks.
stripe set of mirror sets
A multilevel container created from two or more equal-sized
mirror sets.
stripe size
The size that will be used to stripe data or parity information
across the disks in the array.
striping, disk; striped array
Spreading data over multiple disks to enhance performance.
Often referred to as RAID 0, simple data striping provides no
redundancy scheme, and is not technically a standardized
RAID lever.
subsystem
The collection of software and hardware that controls storage
to be managed and monitored.
T
target ID
See SCSI ID.
task
An actively running process such as disk format or array
verification.
An operation that occurs only on the controller, asynchronous
to all other operations. For example, scrub container, clear disk,
and create file system are tasks done on the controller.
