(1) A structure that contains an ordered collection of data elements in which each element can be referenced by its ordinal position in the collection. All elements in an array have the same data type.
(2) An arrangement of data in one or more dimensions, such as a list, table, or multidimensional arrangement of items.
(3) An arrangement of related hard-disk-drive modules that have been assigned to a group.
(4) In programming languages, an aggregate that consists of data objects, with identical attributes, each of which can be uniquely referenced by subscripting. See also vector, scalar.
(5) In EGL, a structure item that has an occurs value greater than one. If an array has a subordinate structure item that also has an occurs value greater than one, the subordinate structure item declares an array with an additional dimension.
(6) A number of items stored together, which a user can quickly retrieve by supplying the correct index.
(7) An ordered collection, or group, of physical devices (disk drive modules) that are used to define logical volumes (LVOLs) or devices. In the ESS, an array is a group of disks designated by the user to be managed with a Redundant Array of Independent Disks (RAID). See also Redundant Array of Independent Disks.
