  • Patent number: 11957608
    Abstract: Aneurysms are treated by filling at least one double-walled filling structure with a curable medium within the aneurysm. The filling structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Scaffolds are placed into the tubular lumens in order to help maintain the shape, anchor the filling structures in place, and provide improved blood flow transition into and out of the tubular lumens.

  • Patent number: 7774544
    Abstract: In an embodiment of the invention, a method and apparatus permits the reliable disk ownership changes. The method and apparatus generate a replay request based on ownership data stored in a persistent memory device, in response to a failure occurrence when ownership is being changed for disks in an aggregate. The method and apparatus will compare an update count in the replay request with an update count in a disk in the aggregate. Based on the comparison of the update count, the ownership on the disk is changed so that each disk in the aggregate will be owned by a same node. The failure occurrence can be, for example, a power failure, a panic occurrence, or a takeover procedure.

  • Patent number: 7631021
    Abstract: An embodiment of the invention provides an apparatus that includes a primary node, a secondary node, and an intermediate node. Data is synchronously copied from the primary node to the intermediate node, and data is asynchronously copied from the intermediate node to the secondary node. The data stored in the intermediate node is a subset of the data set that is stored in the primary node. Therefore, an embodiment of the invention advantageously provides a multiple hop data replication method that allows data recovery if disaster occurs at the location of the primary node. Additionally, an embodiment of the invention advantageously provides a tolerable latency value from the time that a client device sends a write request to the primary node to the time that an acknowledgement message is received by the client device.

  • Publication number: 20070245095
    Abstract: A system and method for enabling parallel replay of a backup memory log of client transaction request entries to a network storage appliance file system is provided. The backup memory is typically implemented as a non-volatile random access memory (NVRAM). An initiator establishes a swarm of messages with a plurality of transaction blocks pointing to logged request entries and related states associated therewith. The states represent the various phases of file system recovery and disk storage including a retrieval of disk information (data and meta-data), typically in the form of a LOAD, and a subsequent modify phase. The swarm is transferred to the file system for parallel disk information-retrieval in an interleaved process. Any transactions that cannot be performed due to a required prerequisite action (e.g. a prior file-create) are returned to the initiator for reloading once the prerequisite action has occurred.

  • Publication number: 20050028111
    Abstract: The present invention is a system that provides an orientation indicator graphical user interface element in a display view of a three-dimensional scene. The orientation indicator can be used to automatically change a view of the scene to a predetermined viewpoint. The indicator includes view direction indicating controls that when activated cause the view of the scene to change to a view direction indicated by the control. The direction can be indicated by a shape of the control, such as by a cone with a point pointing in the direction of the view, or by the location of the control, such as being located on a marked scene axis of the indicator. The view of the scene is also automatically adjusted at the view position to center an object of interest in the scene and zoomed in/out to fit the object to the display view. The indicator is part of the three-dimensional scene and moves with the scene as the scene is manipulated by a user, such as in tumbling the scene.
