  • Publication number: 20190220195
    Abstract: A first plurality of block identifiers is sorted based, at least in part, on a measure of spatial locality. A second plurality of block identifiers is sorted based, at least in part, on the measure of spatial locality. At least the first plurality of block identifiers and the second plurality of block identifiers are incrementally merged into a third plurality of block identifiers based, at least in part, on the measure of spatial locality. A block of data corresponding to metadata associated with a plurality of block identifiers of the third plurality of block identifiers is updated.

  • Patent number: 9965196
    Abstract: Storage systems track free blocks using various data structures and maps. For instance, free block maps may contain data blocks with values that indicate whether a block is free or not. When an operation results in a block being freed, the relevant data block in the maps must be written during an I/O operation to update the value. Large numbers of updates my occur after an operation that frees a large numbers of blocks, which can lead to performance degradation. Accordingly, disclosed are systems and methods for deferring updating of free block data tracking structures using logs.

  • Publication number: 20170308320
    Abstract: One or more techniques and/or computing devices are provided for inline deduplication. For example, a checksum hash table and/or a block number hash table may be maintained within memory (e.g., a storage controller may maintain the hash tables in-core). The checksum hash table may be utilized for inline deduplication to identify potential donor blocks that may comprise the same data as an incoming storage operation. Data within an in-core buffer cache is eligible as potential donor blocks so that inline deduplication may be performed using data from the in-core buffer cache, which may mitigate disk access to underlying storage for which the in-core buffer cache is used for caching. The block number hash table may be used for updating or removing entries from the hash tables, such as for blocks that are no longer eligible as potential donor blocks (e.g., deleted blocks, blocks evicted from the in-core buffer cache, etc.).

  • Patent number: 9639968
    Abstract: One embodiment of the present invention sets forth a technique for generating an augmented view of a location of interest for a user. The technique includes determining an image capture location based on the location of interest, and determining an image capture direction based on the image capture location. The technique further includes receiving an image associated with the image capture location and the image capture direction. The technique further includes processing the image based on a line of sight associated with a location of the user to generate a processed image and displaying the processed image to the user. Advantageously, the disclosed techniques enable a user to see through obstructions in the surrounding environment to view a location of interest.

  • Publication number: 20160110121
    Abstract: It is determined that a first set of one or more blocks associated with a file system are to be freed. Each of the first set of blocks is associated with a block identifier. In response to a determination that the first set of blocks is to be freed, it is determined that a first log has been allocated an insufficient number of data blocks to store the block identifiers that are associated with the first set of blocks. In response to a determination that the first log has been allocated an insufficient number of data blocks, one or more data blocks are allocated to the first log. It is indicated that one or more block identifiers are to be removed from the first log and added to a second log. It is indicated that metadata associated with a second set of one or more blocks is to be updated.

  • Publication number: 20140143288
    Abstract: A technique for efficiently scanning various datasets in a storage system to generate metadata for shared data blocks is provided. In one embodiment, data containers in an active file system of a storage object are first scanned. Remaining images (e.g., snapshots of the file system) are arranged in a chronological order based on the age of such images in the storage object. In some instances, to perform a metadata scan of a given image, the storage server compares each data container in the given image to a corresponding data container in a prior image (from the chronological order) to identify any non-identical data blocks (i.e., blocks that are not common between the data containers of the two images) in each data container. The metadata scanner then generates metadata only for the non-identical data blocks in each data container and skips metadata generation for any remaining data blocks.

  • Publication number: 20100211616
    Abstract: A computer having deduplicated data stores files comprised of file blocks in a volume. File blocks are copied from the volume to memory as needed by processes. An operating system searches a memory index for physical attributes associated with a deduplicated file block to determine whether a copy of the deduplicated file block is already resident in the memory. If a copy of the deduplicated file block is already resident in the memory, the operating system creates another copy of the deduplicated file block within the memory and updates the memory index, thus avoiding having to copy the deduplicated file block from the volume and improving the performance of the computer.

  • Patent number: 7539759
    Abstract: A protocol for extending session endpoints in an ad-hoc network environment first performs device discovery to determine local devices within its coverage area and the capability of those devices. These local devices then exchange session descriptions with the endpoint device. If the current session may be supported by one of the local devices, the endpoint device, responsive to a command from an user, transfers the session endpoint to the local device and the endpoint device acts as a proxy for the local device in the session. Optionally, if the local device has a path to the correspondent node that is independent of the path through the endpoint device, it establishes the session along this path and then signal the endpoint node to terminate its session.

  • Publication number: 20070143370
    Abstract: An automatic metadata generation service system for use in home networks includes a home network interface adapted to perceive user network activity on a home network. A metadata generation service module generates user metadata based on the user network activity. An update service module automatically updates one or more existing metadata sets on the home network with generated metadata. In other aspects, a metadata generation service system for use with a home network, includes a home network interface adapted to interact with one or more of content providers or service providers according to one or more service discovery protocols. A monitoring service module obtains an update of metadata from one or more of the providers. A metadata generation service module convert metadata of one format received via the update to metadata of another format required by the home network.

  • Publication number: 20070115883
    Abstract: A method for use in a mobile device to expedite hand-off of mobile devices between access points first detects movement of the mobile device among the coverage ranges of the access points. A mobile device that moves from one access point to another periodically transmits information on the data link level connection of its new access point on the channel used to access its prior access point. A first mobile device that is coupled to access points in a particular area maintains network level access information for access points with which it has communicated. When a new mobile device enters the area, the first device detects the new device and transmits the list to the new mobile device, enabling the new device to connect to an access point without transmitting a router solicitation message or receiving a router advertisement message.
