  • Patent number: 9442839
    Abstract: A non-volatile storage system comprises a controller and one or more memory die in communication with the controller. The controller sends data and an initial address in conjunction with a request to program the data to one of the memory die. The memory die comprises a plurality of non-volatile storage elements and one or more control circuits. The one or more control circuits attempt to program the data to the non-volatile storage elements at the initial address and determine that programming of the data at the initial address fails. The one or more managing circuits automatically identify a new address in the memory die without the memory die being instructed of the new address by the controller and program the data at the new address on the memory die without the data being re-transmitted from the controller to the memory die.

  • Patent number: 9441175
    Abstract: A process to produce low ash clean coal from high ash coal with substantially complete solvent recovery, the process including: forming a slurry of coal fines in a N-Methyl-2-pyrrolidone (NMP) and Ethylenediamine (EDA) solution; maintaining said slurry in a reactor at a temperature range of 100° C. to 240° C. and a pressure range of 1 to 4 gauge (kg/cm2) for a period of about 15 minutes to 4 hours; separating the produced sample withdrawn from the reactor, one part being a filtrate and the other a reject; feeding the filtrate into an evaporator to recover 80-85% solvent; precipitating the concentrated filtrate material in an anti-solvent tank to separate coal from solvent; separating the coal by filtration, said separated coal having a reduced ash content; feeding the anti-solvent and solvent mixture into a distillation column to separate remaining solvent from the anti-solvent for reuse in the process.

  • Publication number: 20160154707
    Abstract: A data storage environment can include one or more virtual clients instantiated on a host proxy computing device. The virtual clients may have only indirect access to a storage device, and may access the storage device via the proxy computing device. For example, the proxy computing device receives storage operation requests from one of the virtual clients, such as a request to create, mount or revert a snapshot of virtual client data. The proxy computing device generally acts as an intermediary between the virtual clients and the storage device to carry out the snapshots or other storage operations. The proxy computing device may further receive a notification upon completion of the storage operations, and transmits relevant data to the requesting virtual client regarding the storage operation.

  • Publication number: 20160147472
    Abstract: The systems and methods herein permit storage systems to correctly perform data recovery, such as direct access recovery, of Network Data Management Protocol (“NDMP”) backup data that was modified prior to being stored in secondary storage media, such as tape. For example, as described in greater detail herein, the systems and methods may permit NDMP backup data to be encrypted, compressed, deduplicated, and/or otherwise modified prior to storage. The systems and methods herein also permit a user to perform a precautionary snapshot of the current state of data (e.g., primary data) prior to reverting data to a previous state using point-in-time data.

  • Publication number: 20160139836
    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.

  • Publication number: 20160112993
    Abstract: A dynamic spectrum arbitrage (DSA) system may include a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. A dynamic spectrum arbitrage application part (DSAAP) protocol/component/module may allow, facilitate, support, or augment communications between the DSC and DPC so as to improve the efficiency and speed of the DSA system. The DSAAP may allow the DPC and/or DSC components to better pool resources across the different networks, better monitor traffic and resource usage in the various networks, to more efficiently communicate bids and bidding information, to quickly and efficiently register and deregister components, and better perform backoff operations.

  • Publication number: 20160092128
    Abstract: A storage module may be configured to organize data to be moved from an initial storage location to a destination storage location into sets, and to determine whether to commit the data to the destination storage location on a set-by-set basis. Error correction and/or a post write and read process may be performed on the sets that are copied to the destination storage location to determine whether to commit each of the copied sets.

  • Publication number: 20160092325
    Abstract: A memory system logs failures to optimize garbage collection in partial bad blocks that are reused in non-volatile memory. A failure in a primary block may be logged in an inverse global address table. A garbage collection operation can reference the log in order to automatically avoid the failure in the primary block when the primary block is picked as the source block for garbage collection. Likewise, the garbage collection operation may scan only the logged wordlines in the secondary block when the secondary block is picked as the source block for garbage collection.

  • Publication number: 20160092129
    Abstract: A method and system for folding only a portion of data from an SLC block to an MLC block is described. The method includes identifying word lines with only valid data and word lines with non-valid data in a selected SLC block, copying data only from word lines with valid data to a destination MLC block and copying data from word lines in the selected SLC block with non-valid data to a separate SLC compaction block. The system includes a first controller module configured to scan for word lines with only valid data and pass only a bitmap regarding valid and invalid word lines to a second controller module. The second controller module is configured to perform on-chip folding of data from valid word lines, and to copy data from invalid data word lines to an SLC compaction block.

  • Publication number: 20160065671
    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.
