Abstract: Many storage-area networks (SANs) are structured so that an end-user or client-computer can access data on one or more target storage devices through a storage router and a separate Fiber Channel (FC) switch. However, the conventional use of a separate FC switch to couple the storage router makes it difficult and time consuming to restore zone configuration of the FC switch. Accordingly, the present inventor devised, among other things, an exemplary method of automatically maintaining and synchronizing a copy of zone configuration data for an FC switch. Through these and/or other features, the exemplary embodiment ultimately reduces the cost and complexities associated with implementing storage-area networks.

Abstract: Many storage-area networks (SANs) were developed to facilitate high-speed storage of large quantities of digital data. However, at least some conventional SANs present increased maintenance costs and complexities that can discourage their use. For example, in some SANs, its difficult and time consuming to properly reconfigure a Fiber Channel switch after a system failure since the switch is configurable by multiple entities. Accordingly, the present inventors devised, among other things, a method and systems for automatically maintaining and synchronizing one or more backup copies of configuration data.

Abstract: The invention provides a method and apparatus for animating and coloring hydraulic, electrical, electromechanical and similar schematic systems, components and designations to anble repeatable visual review and study. The invention provides, inter alia, a training aid for study, evaluation, design and maintenance of a system.
