Abstract: A trailer for use with off-road vehicles such as all-terrain vehicles and snowmobiles. The disclosed off-road trailer can be adjusted to accommodate different trailer beds and attachments that can be readily off loaded and can be compactly packaged for shipping and storage. Modules for different conditions (e.g., ground or snow surface) can be implemented for multi-season usage. The disclosed suspension assembly enhances performance and robustness while maintaining cost effectiveness. The utility of the disclosed off-road trailer may be enhanced by grab handles for manual maneuvering, a rear bumper, and an active tail light. The overall design of the off-road trailer enables towing cargo behind a snowmobile or off-road vehicle over rough terrain at higher rates of speed than conventional off-road towable trailers.

Abstract: A wing lock and deployment apparatus for an air launched vehicle includes a driver acted on by a single linear actuation event. The disclosed wing lock and deployment apparatus is capable of unlocking deployable wings of an air launched vehicle, deploying deployable wings of the air launched vehicle from a stored position, and locking deployable wings of the air launched vehicle in a deployed position in sequential order with the one single linear actuation event.

Abstract: Techniques are presented for clustering data storage including (a) announcing, using zeroconf, to a local network, a service provided by a DSA and an unreserved state of the DSA, the service being of a clusterable data storage type, (b) receiving a cluster command from a configuration management device connected to the local network, the cluster command directing the DSA to join a storage cluster to present combined storage of the DSA and at least one other DSA, and (c) in response to receiving the cluster command: (1) announcing to the local network via L2 multicasting that the DSA has entered a reserved state using zeroconf, (2) afterwards, performing configuration operations including updating system parameters, resulting in the DSA becoming part of the storage cluster, and (3) while in the reserved state, receiving another cluster command directing the DSA to join another storage cluster, and, in response, refusing the other cluster command.

Abstract: A primary copy and one or more shadow copies of a logical volume are created and discovered by a host rescan performed when the logical volume is initially created. Data storage resources are allocated to the primary copy, but not to the shadow copy. The initial path state of the logical volume describes the path to the primary copy as active, and the path to the shadow copy as unavailable for accessing the logical volume. Movement of the logical volume to the storage appliance providing the shadow copy can be performed without an additional host rescan, by making the shadow copy the new primary copy, making the primary copy a new shadow copy, and updating the path state of the logical volume to indicate i) that the path to the new primary copy is active, and ii) that the path to the new shadow copy is unavailable.

Abstract: A method, computer program product, and computing system for monitoring the availability of multiple redundant data sources within a high-availability data environment. The inaccessibility of at least one of the multiple redundant data sources is detected, thus defining at least one inaccessible data source. Which software applications are impacted by the at least one inaccessible data source is determined, thus defining at least one impacted software application. A notification is provided to one or more parties associated with the at least one impacted software application concerning the inaccessibility of the at least one inaccessible data source.
