The file, instead of all of the individual segment files, may be easier to manage and/or may improve I/O efficiency due to the reading and writing of a larger file possibly across a plurality of parallel disks. A playlist of the content is updated to refer to the file and a location within the file for each segment, rather than referring to individual segment files for each segment.

Abstract: A global recently used files list identifies files recently accessed by a user through one or more network services and files accessed by the user that are stored locally on a computing device. In order to generate the global recently used files list, a network recently used files list is retrieved that identifies files that were recently accessed through the one or more network services. Applications may update the network recently used files list each time a user accesses files by way of a network service. The network recently used files list may then be merged with a local recently used files list that identifies recently accessed locally stored files in order to generate the global recently used files list. Applications may update the local recently used files list each time files are accessed that are stored locally on a computing device.

Abstract: Systems and methods are described that facilitate idempotent execution of commands generated by a client for execution by a database server. Each command transmitted to the server includes a command ID generated by the client. The server attempts to execute each command and subsequently stores the command ID associated therewith in a repository along with an indication of whether the command executed successfully. When a new command is received by the server, it determines if the command ID associated therewith has already been stored in the repository. If the command ID associated with the new command has not already been stored in the repository, then the server executes the new command. If the command ID associated with the new command has already been stored in the repository and a previously-received command associated with the command ID has been executed successfully, then the server will not execute the new command.

A Gigabit Ethernet IP network transfers read and write data between the compute nodes and the storage access servers. The storage access servers are linked to the data storage devices for parallel access to iSCSI LUNs of the file data in the data storage devices. The metadata server is programmed for server load balancing by indicating to the compute nodes respective ones of the storage access servers that should be used for access to the iSCSI LUNs.

Abstract: Described is a technology by which Map-Reduce runtimes and distributed array runtimes are interoperable. Map-Reduce chunks are processed into array data for processing in a distributed array runtime based upon merge information. A staging Map-Reduce job tags a chunk with tag information that indicates a relative position of the chunk in an array. A distributed array framework imports files produced via a Map-Reduce framework and provides an array to an application of the distributed array framework for processing. An export mechanism may output one or more Map-Reduce files from the distributed array framework.

Abstract: A fingerprint is computed from selected metadata of binary files, and used in determining whether to regenerate code-behind file(s). In one case, after ascertaining that a binary-file-set's current metadata-fingerprint differs from a previous metadata-fingerprint, the corresponding code-behind-file-set is regenerated. A code-behind file may also be regenerated, even though its current fingerprint matches its previous fingerprint, because its metadata has changed. If the current fingerprint matches the previous fingerprint and metadata is unchanged, regeneration can be avoided. The fingerprint may consist of, or merely contain, definitions of classes, properties, and other items, and may be limited to metadata that is used when generating the code-behind-file-set. System assemblies are not fingerprinted. Timestamps may be used. Metadata-fingerprint computation code and regeneration determination code are described.

Abstract: Detecting data duplication comprises maintaining a fingerprint directory including one or more entries, each entry including a data fingerprint and a data location for a data chunk. Each entry is associated with a seen-count attribute which is an indication of how often the fingerprint has been seen in arriving data chunks. Higher-frequency entries in the directory are retained, while also taking into account recency of data accesses. A data duplication detector detects that the data fingerprint for a new chunk is the same as the data fingerprint contained in an entry in the fingerprint directory.

Abstract: Multiple file system events are detected on one or more nodes of a file system, each file system event corresponding to an operation that is to be performed on the file system.

A programmatic component that is external to the file system can process entries from the journal, and in response, the entries can be expired from the journal.

Abstract: Example apparatus and methods concern a file system based interface between a disk-based network attached storage device and a linear tape open (LTO) linear tape file system tape. One example method may include controlling a device (e.g., backup server) to read a file from the NAS device using a shared file system (e.g., NFS, CIFS) and controlling the device to write the file to the LTO tape device using the LTFS.

Abstract: A file storage performs control to create a virtual parent file having an identifier capable of uniquely identifying a parent file among storage systems and volumes, and to acquire block layout information of the parent file using said identifier. The file storage creates a virtual parent file in the volume in which the clone file is created, and sets the file as a virtual parent file of the clone file so as to enable creation of a clone file of a parent file that exists in a different volume or a different storage system. Moreover, by combining creating the virtual parent file and switching the identifier of the parent file which is pointed by the virtual parent file, migration of clone files and parent files astride storage systems and volumes is enabled.
