L
legacy disk
Disk that contained a valid partition table when connected to the controller. The controller manages the
disk as a legacy disk array where there is a one-to-one logical-to-physical mapping of array to disk.
logical device
Volume comprised of space from one or more physical drives and presented to the operating system as if it
were a single storage unit.
low-level format
Process performed by the drive firmware that completely cleans any data off the hard disk.
M
mirrored array/mirroring
See
RAID 1
,
RAID 10
.
monitoring
Process of receiving, displaying, and logging system events.
N
Native Command Queuing
Allows disk drives to arrange commands into the most efficient order for optimum performance.
O
offline array
Array that can no longer be accessed.
optimal
The state of an array when it is fully operational. For redundant arrays, the entire array is protected.
P
partition
A section of a disk storage device created by the operating system disk management program, in which data
and/or software programs are stored. Computers have a primary operating system partition that contains
the special files needed to boot the computer. Each operating system partition is assigned a unique drive
letter, such as C or D. A single disk device can have multiple partitions.
phantom object
Object that represents a component that cannot be configured by the controller management software; for
example, a missing drive.
Q
quick init
An array configured using the Quick Init option is available immediately, with no on-going background
controller activity. All data written to an array that has been quick configured is protected.
