DEFINITION

Classification: 711/114

Arrayed (e.g., RAIDs):

(under subclass 112) Subject matter where a plurality of direct access devices are arranged in an array and files or portions thereof are stored on more than one of the direct access storage devices.

(1) Note. This subclass is appropriate for redundant arrays of inexpensive disks (RAID).

(2) Note. See the (6) Note to subclass 100 for systems directed to reliability and availability of DASDs. See the SEARCH CLASS notes below.
