  • Patent number: 10025523
    Abstract: Described are techniques for processing a data request for a device of a data storage system. A data request directed to a device that is a virtualized device of the data storage system is received. The data storage system has a plurality of devices comprising one or more local devices and one or more virtualized devices. Each of the local devices is a storage device included in the data storage system and each of the virtualized devices is an external storage device with respect to the data storage system and is presented as a local storage device of the data storage system. First processing is performed by a disk adapter in connection with servicing the data request for the device. The first processing includes sending the request to an external storage device corresponding to the virtualized device over a connection in accordance with path information obtained from discovery processing.

  • Patent number: 9383940
    Abstract: Described are techniques for performing data migration for a source logical volume and a target. The target is configured as storage for another mirror of the source logical volume prior to copying data from the source logical volume to the target, and if the target is configured storage of another logical volume of the data storage system, the configured storage is remapped as storage for another mirror of the source logical volume prior to copying data from the source logical volume to the target. One or more invalid bits are set indicating that the target does not contain a valid copy of data from the source logical volume. Data is copied from the first mirror of the source logical volume to the target. Invalid bits are cleared as data portions of the first mirror of the source logical volume are copied to the target.

  • Patent number: 9104963
    Abstract: A method of visualizing a plurality of designs which comply with a plurality of objectives. The method comprises acquiring a plurality of designs each represented by sequential multivariate data indicative of a compliance with a plurality of objectives, generating an objective anchored based self-organizing map (SOM) having a plurality of objective anchors and maps the plurality of designs in an objective space, and outputting the objective anchored based SOM. Each objective anchor is associated with one of the plurality of objectives, each the design is visualized in the objective anchored based SOM by an indicator which the distance thereof from each the objective anchors is indicative of a compliance thereof with a respective the associated objective in relation to other of the plurality of objectives.

  • Patent number: 8930150
    Abstract: Systems and methods for detecting leaks in a fluid distribution network are provided. In one embodiment, the method includes calculating value of non-revenue fluid. Further, the method includes receiving data corresponding to pressure from pressure sensors in the fluid distribution network and receiving data corresponding to flow from flow sensors in the fluid distribution network. Furthermore, the method includes estimating pressure values at the pressure sensors and estimating flow values at the flow sensors. The received data and estimated values of respective sensors for corresponding time periods are compared. Existence of leak in the fluid distribution network is detected if the value of non-revenue fluid is non-zero. One or more leak spots are located, if a leak is detected, by solving an optimization problem.

  • Patent number: 8533163
    Abstract: Handling a database request includes providing a first database manager on a storage device containing data for the database, generating the database request external to the storage device, providing the database request to the first database manager on the storage device, and the first database manager servicing the database request by obtaining data internally from the storage device and processing the data within the storage device to provide a result thereof, wherein portions of the data that are not part of the result are not provided externally from the storage device. Handling a database request may also include providing a host having a database application running thereon. The database request may be generated by the database application. Handling a database request may also include providing a second database manager on the host, where the second database manager communicates with the first database manager to provide the database request.

  • Patent number: 8028062
    Abstract: A system creates a storage area network (SAN) centric storage virtualization layer in front of storage devices. The system allows data mobility and migration without disruption to the one or more host servers attached to the SAN. Specifically, the host servers are not disrupted when switching I/Os between physical and virtual storage, for example, by taking advantage of WWPN spoofing and Fibre Channel VSAN technology. The use of VSANs effectively allow multiple virtual directors and/or switches to be created within a physical director and/or switches, each with their own separate name server, thereby providing complete isolation from one another. The host-storage pathing information is unchanged as the original physical storage port's WWPNs are spoofed by the virtual storage port. The result is two identical WWPNs within the SAN which is normally disallowed; however, by separating the physical port WWPN into one VSAN and the virtual port WWPN into another, the restriction may be circumvented.

  • Publication number: 20080010290
    Abstract: Offloading application processing from a host processor system includes providing a first part of the application on the host processor system and providing a second part of the application on a storage device containing data for the application. The first part of the application communicates with the second part of the application to generate requests from the first part of the application to the second part of the application. The second part of the application services the requests by obtaining data internally from the storage device and processing the data within the storage device to obtain a result that is provided from the second part of the application to the first part of the application. Portions of the data that are not part of the result are not provided. Shared memory of the storage device may be used to obtain data internally.

  • Patent number: 7111298
    Abstract: In a multi-processor system in which several processors compete for exclusive use of a shared resource, a claimant processor asserts exclusive access to a resource by determining whether there exists a competing claim to exclusive access to said resource and then posting a claim to exclusive access to said resource. Following lapse of an interval, the claimant processor then determines whether there exists a competing claim to exclusive access to said resource. Depending on whether or not such a claim exists, the claimant processor then either takes control of the resource or makes another attempt after waiting.
