Abstract : The objective of this effort is to design, fabricate, test, deliver and support an Optical Redundant Array of Independent Risks (O-RAID) subsystem for use at Rome Laboratory to demonstrate mass data storage and retrieval operations. In developing new concepts and systems for mass storage, performance and reliability are important features. The O-RAID storage subsystem is designed to enhance the capabilities offered by traditional optical disk drives and RAID storage systems. The O-RAID connects to a variety of host computer systems to provide a high performance, highly reliable mass storage system. The O-RAID design combines the redundant features prescribed to magnetic disk storage with the infinite near line capabilities, removability and archivability of optical disk technology. The subsystem design derives as an integrated storage product consisting of multiple optical disk drives designed to appear as a single disk to a host computer.
