Adaptec 2200S Snapshot, Spanned volume, Spare, Stripe size, Stripe set of RAID, Task

Glossary

snapshot

Instantaneous read-only copy of an array at a precise point in time.

spanned volume

Concatenation of segments on two or more drives.

spare

See hot spare.

stripe

Contiguous set of data distributed across all the disks in an array. A stripe set distributes, or stripes, data evenly across its respective disks in equal sized sections called stripes.

stripe size

In striped array types, (RAID 0, RAID 5, RAID 10, RAID 50) data is distributed, or striped, across the member disks in equally-sized sections. The amount of data in each section on a disk is the stripe size.

stripe set

See RAID 0.

stripe set of mirror sets

See RAID 10.

stripe set of RAID 5

See RAID 50.

T

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.
