A storage device initiates a change in its file system and locally stores it for future updates of the file system. The host device sends a command to the storage device and the storage device responds by commencing a synchronization process during which the two parties coordinate the update of the file system with the stored change.

Synchronizing changes in a file system which are initiated by a storage device and a host device

A local storage device (LSD) is provided configured to have a host device (HD) in communication with the LSD. The LSD includes a memory array. The LSD is configured to characterize data access usage of the LSD by at least one program executing on the HD. The LSD is configured to monitor access to the LSD as a result of data access operations by the HD relative to the memory array of the LSD. The LSD is additionally configured to determine characteristics of the monitored access. The LSD is additionally configured to, based on characteristics of the monitored access, determine and store data on the LSD indicative of the characterized monitored access.

Data usage profiling by local storage device

A storage device coordinator intercepts a memory command issued by a host device and intended for a target storage device which is one of a plurality of storage devices, and, if the memory command is not optimal, transforms the memory command into one or more storage commands, each being associated with a respective storage device selected from the plurality of storage devices according to an optimization rule. A host device is also provided, which includes the storage device coordinator. A data storage system is also provided, which includes the storage device coordinator.

Storage device coordinator and a host device that includes the same

A method of using a device, including monitoring host activity in an autonomous manner, without the host reporting to the device about its activity. The method also including initiating communications from the device and using resources of the host for such communications, thereby enabling the device to function as a proactive device.

Method of monitoring host activity

A local proxy system includes a storage device having a local proxy and a physical port connection. The local proxy is part of a split proxy configuration having a local proxy and a remote proxy. The physical port connection is operative to receive commands from a host via an internet application protocol; and to transmit commands to the host via a modem control protocol, to thereby function as a gateway for conveying these commands to a remote proxy, via the host. Also provided is a method of optimizing communication over a network; and a local proxy system that includes a storage device having a local proxy. The storage device is in connection with a host via a physical port connection complying with a standard storage device interface.

Local proxy system and method

A computing device including a host device (HD) is in communication with a local storage device (LSD), wherein the LSD includes a memory array. A search index is generated with respect to data stored in the memory array of the LSD. By the LSD without involvement of the HD, the index data is generated with respect to the data stored in the memory array of the LSD. By the LSD, the generated index data is stored on the LSD as at least a part of the search index. The index may include data that can be used to respond to search queries with respect to data of the LSD. The queries may be originated from a HD or from within the LSD. The use of the index is not limited to responding to search queries. For example, the index may be used for content screening.

Data indexing by local storage device

A method of servicing a command sent from a host device file system (HDFS) within a host device (HD) by a local storage device (LSD) in communication with the HD is described. The method includes receiving a first command at the LSD instructing the LSD to execute an operation on associated logical addresses. If the first command is associated with at least a first set of logical addresses, the method includes servicing the first command by the LSD at least by way of sending a second command to a device (RD) external to the LSD that instructs the RD to execute an operation on memory locations within the RD. If the first command is not associated with the first set of logical addresses, the method includes servicing the first command by the LSD only by way of operations executed by the LSD on memory locations within the LSD.

Storage system with local and remote storage devices which are managed by the local storage device

When a storage device initiates a change in its file system, it locally stores it for future update of the file system. When the host device sends a command to the storage device, the storage device responds to it by commencing a synchronization process during which the two parties coordinate the update of the file system with the stored change. If there are no file system changes pending in the host device, the storage device gets permission from the host device to update the file system with the change and, then, the host device reads the updated file system from the storage device. If there are file system changes pending in the host device, the host device updates a representation of the file system residing in the host device, causes the storage device to make the same changes, and then the storage device initiated change, in the file system. Lastly, the host device receives information from the storage device regarding the changes initiated by the storage device.

The embodiments described herein generally relate to a local mass storage device that provides a suggested read list of digital data to a host device. In one embodiment, a method is provided in which a local mass storage device receives a request from a host device for a suggested read list of digital data stored in the local mass storage device. The local mass storage device creates the suggested read list and provides the suggested read list to the host device. In this embodiment, the local mass storage device is managed by the host device using a logical block addressing protocol.

Method for providing a suggested read list of digital data to a host device

Various methods, devices and systems are described for providing distributed storage services. A data storage device is capable of initiating a communication session with an external entity such as a local host computer (and vice versa) coupled directly to the data storage device, a remote server computer, or directly with remote data storage devices with or without intervention by a local host computer.

Storage device having direct user access

Distributed storage service systems and architecture

A number of applications can be run by the computing system. Such applications can execute independently from each other and can also each independently manage a corresponding set of content stored on a local storage device (LSD). One of the advantages presented by the invention is the ability of the LSD to inform one application of the content made available on the LSD by another one of the applications even though the applications have no relationship to each other. In this way, a synergy between the independent applications can be achieved providing a co-operative environment that can result in, for example, improved operation of the computing system, improved resource (i.e., memory, bandwidth, processing) allocation and use, and other factors.

Cache management

Various methods, devices and systems are described for providing dual representation of stored digital content are described where the dual representation includes logical block data and corresponding data objects. Data object property information is synchronized with the data objects.

Dual representation of stored digital content

Digital content distribution and consumption that provides the advantages of digital content being locally stored under user control while concurrently having the widest acceptance by legacy players/platforms (i.e., no need to perform complex software integration) while still remaining compatible with state of the art security in order to satisfy content provider requirements.
