  • Patent number: 10942894
    Abstract: An information management system according to certain aspects may determine whether storage operations will work prior to executing them. The system may check various factors or parameters relating to a storage policy to verify whether the storage policy will work at runtime without actually executing the policy. Some examples of factors can include: availability of primary storage devices, availability of secondary storage devices, license availability for performing that operation, user credentials for connecting to primary and/or second storage devices, available storage capacity, connectivity to storage devices, etc. The system may also check whether a particular system configuration is supported in connection with storage operations. The result of the determination can be provided in the form of a report summarizing any problems found with the storage policy. The report can include recommended courses of action or solutions for resolving any identified issues.

  • Publication number: 20210028015
    Abstract: A method for removing a native oxide film from a semiconductor substrate includes repetitively depositing layers of germanium on the native oxide and heating the substrate causing the layer of germanium to form germanium oxide, desorbing a portion of the native oxide film. The process is repeated until the oxide film is removed. A subsequent layer of strontium titanate can be deposited on the semiconductor substrate, over either residual germanium or a deposited germanium layer. The germanium can be converted to silicon germanium oxide by exposing the strontium titanate to oxygen.

  • Publication number: 20210011805
    Abstract: A data storage system according to certain aspects can share a single snapshot for multiple applications and/or agents. For example, the data storage system can receive snapshot commands from multiple applications and/or agents, and can group them for a single snapshot (e.g., based on time of receipt of the snapshot commands). Data associated with the multiple applications and/or agents may reside on a single LUN or volume. The data storage system can take a single snapshot of the LUN or volume, and generate metadata regarding which portion of the snapshot is related to which application. The single snapshot can be stored in one or more secondary storage devices. The single snapshot may be partitioned into portions relating to different applications and stored separately.

  • Patent number: 10891197
    Abstract: The illustrative systems and methods consolidate storage-array command channels into a media agent that executes outside the production environment. A “snapshot-control media agent” (“snap-MA”) is configured on a secondary storage computing device that operates apart from client computing devices. A “forwarder” media agent operates on each client computing device that uses the storage array, yet lacks command channels to the storage array. Likewise, a “forwarder” proxy media agent may operate without command channels to the storage array. No third-party libraries or storage-array-command devices are installed or needed on the host computing device. The forwarder media agent forwards any commands directed at the storage array to the snap-MA on the secondary storage computing device. The snap-MA receives and processes commands directed at the storage array that were forwarded by the forwarder media agents. Responses from the storage array are transmitted to the respective forwarder media agent.

  • Publication number: 20200372371
    Abstract: A system and method for optimizing solution identification for a problem is provided. The invention comprises generating multiple solutions for the problem by selecting population of datasets from a search space. Further, fitness of each generated solution is determined by utilizing a fitness approximation model for selecting solutions from the generated solutions for generating a next generation of solutions until the solutions converge based on a pre-determined convergence target. Further, solutions from the converged solutions are filtered by utilizing a filtering model for performing a concrete evaluation. The concrete evaluation is performed for identifying productive solutions and unproductive solutions from the solutions filtered from the converged solutions. Further, a feedback based on the concrete evaluation is provided. Furthermore, the solution identification for a problem is carried out iteratively until a termination condition is met.

  • Publication number: 20200272543
    Abstract: An illustrative approach to managing snapshots streamlines how and when snapshots are generated in a storage management system, such that fewer snapshots may be generated without diminishing the scope of data protection. A novel unified-snapshot storage policy may govern snapshots for any number of subclients. A unified-snapshot job based on the unified-snapshot storage policy enables the illustrative storage management system to automatically discover relevant components and generate at most one snapshot per target logical unit number (“LUN”) in a storage array. Each snapshot may comprise the data of any number of subclients and/or clients in the storage management system. Accordingly, one unified-snapshot job may yield a minimum but sufficient number of snapshots comprising data of all subclients associated with the governing unified-snapshot storage policy. An enhanced storage manager may manage the unified-snapshot jobs.
