  • Technique for information protection on fault-tolerant redundant information storage devices
    Patent number: 5126889
    Abstract: The present invention relates to a technique which provides swift and easy error correction and detection on one or more fault-tolerant redundant storage devices. In the presence technique, an information packet including (a) the destined storage location identifier in a first section, (b) the information in a second section, and (c) a unique monotonically increasing number in a third section, is sent by a processor to one or more redundant storage device controllers for storage in relative locations of the redundant storage device(s), where the monotonically increasing number is incremented and applied to each sequential information packet to be stored on the redundant storage device(s).
