Glossary

stripe

Contiguous set of data distributed across all the disks in an array. A

striped array distributes data evenly across all members in equal-

sized sections called stripes.

stripe size

The amount of data in each section of a striped array.

striped array

See RAID 0.

task

An operation that occurs only on the RAID controller,

asynchronous to all other operations; for example, initializing a

disk or verifying an array. Some tasks can take an extended period

of time, particularly if the RAID controller is also performing

intensive data I/O while the task is running.

verify

Low-level check that a drive, logical device, or hot spare is good. In

a RAID 1, verify is a low-level check that contents of both members’

segments are consistent and, optionally, corrects errors while

assuming that the master drive is correct. In a simple volume, verify

performs a low-level check that the whole drive can be read.

volume

See simple volume, spanned volume.
