MSI MS-9246 Single-level array, Snapshot, Spanned volume, Stripe size, Striped array, Task

MS-9246 1U Rackmount Server

single-level array

Array created from one or more segments. See also volume, spanned volume, RAID 0, RAID 1.

snapshot

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

spanned volume

A simple volume that spans two or more drives.

stripe

Contiguous set of data distributed across all the disks in an array. A striped array distributes data evenly across all members in equalized sections called stripes.

stripe size

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

striped array

See RAID 0.

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.

V

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.
