Common name for a RAID unit. A term for a unit that groups hard drives (sometimes called striping) to provide increased storage capacity, speed and data security.
A linked group of small, independent drives used to replace larger, single disk drive systems and addressed by a computer as one unit. See also RAID.
A collection of disks logically arranged into an object. Arrays tend to provide benefits such as redundancy or improved performance. Also see disk enclosure and JBOD.
an external device which may contain many hard drives, but looks like one disk (has one ID) to a connected SGI machine
a set of disk drives that make up a larger logical disk, which is sometimes called a logical volume
A collection of disks from one or more disk subsystems combined using a configuration utility. The utility controls the disks and presents them to the array operating environment as one or more logical drives.
A set of two or more disks that might appear to the system as one large disk. A disk array can be a software or hardware device.
A disk array which contains multiple disk drives. Disk arrays, also known as RAID, allow disk drives to be used together to improve fault tolerance, performance, or both. Disk arrays are commonly used on servers.
(n.) One or more physical disk drives that can form a single logical drive. For example, the SPARCstorageTM Array Subsystem for Disk Expansion is a disk array. A disk array can contain several disk drive trays. See also composite drive, redundant array of independent discs (RAID).
Combining redundant disk drives for more capacity, speed, or for disaster recovery
An arrangement of two or more hard disks, in RAID or daisy-chain configuration, organized to improve speed and provide protection of data against loss.
In the context of disk subsystems, a collection of one or more groups of disk modules and one or more SCSI buses that participate in a RAID redundancy scheme. Each group in an array appears to the operating system as a single physical disk.
A collection of disks form one or more commonly accessible disk systems, combined with an Array Management Function (q.v.). The Array Management Function controls the disks¡¦ operation and presents their storage capacity to hosts as one or more virtual disks. The ANSI X3T10 committee refers to the Array Management Function as a storage array conversion layer (SACL). The committee does not have an equivalent of the term disk array in the sense in which it is used by the RAID Advisory Board.
A collection of disks from one or more disk subsystems controlled by array management software. The array management software controls the disks and presents them to the array operating environment as a virtual disk.
A disk array is an enterprise storage system which contains multiple disk drives. It is differentiated from a disk enclosure in that an array has cache and intelligence so that it can perform functions like RAID and virtualization.
