Abstract: Systems and methods providing a location-aware resource locator model for facilitating communication with networked electronic devices are generally disclosed herein. One embodiment includes a resource locator using a standard Uniform Resource Locator (URL) format, but enabling identification of one or more devices based on logical location information provided in the resource locator. The resource locator may also enable identification of the one or more devices based on logical proximity information (such as a logical term indicating a location property) relative to a dynamic location. Further disclosed embodiments include uses of a hierarchical structure to define logical terms and classes for use with a resource locator, and various location determination and lookup techniques used in connection with accessing an electronic device.

Abstract: An embodiment includes a secure and stable method for sending information across a compute continuum. For example, the method may include executing an application (e.g., video player) on a first node (e.g., tablet) with a desire to perform “context migration” to a second node (e.g., desktop). This may allow a user to watch a movie on the tablet, stop watching the movie, and then resume watching the movie from the desktop. To do so in a secure and stable manner, the first node may request security and performance credentials from the second node. If both credential sets satisfy thresholds, the first node may transfer content (e.g., encrypted copy of a movie) and state information (e.g., placeholder indicating where the movie was when context transfer began). The second node may then allow the user to resume his or her movie watching from the desktop. Other embodiments are described herein.

Abstract: Method and apparatus for logging and analyzing event flows associated with execution of a service request in a software system, such as a computer-based system comprising a multi-disc data storage array. Execution of the service request results in a plurality of events carried out by multiple layers of the software system. A global event log accumulates a corresponding plurality of entries which associates each of the events carried out by the multiple layers. An event trace facility preferably accesses the global event log to provide a sequence of the entries corresponding to the service request, such as in a tree structure or time sequence order displayed by a graphical user interface. A log manager preferably controls operation of the global event log. Entries in the global event log are preferably entered sequentially for each ongoing process, and each entry preferably includes an identifier that identifies the associated service request.

Abstract: One embodiment of the present invention provides a system that facilitates validation of data retrieved from a secondary storage device. The system operates by receiving a write request to write new data to a block of the secondary storage device, and calculating a new checksum value from the new data. The system also retrieves a current checksum value and an old checksum value associated with the block of the secondary storage device. Next, the system performs a checksum write operation to a validation device to update the current checksum value and the old checksum value, and then performs a data write operation to the secondary storage device to write the new data to the block of the secondary storage device.

Abstract: A method and apparatus for storing associated data in a computing system having two or more storage devices arranged in a RAID configuration. The storage devices have a prewrite area for pre-storage of the data, and data region for persistent storage of the data. A scoreboard memory structure is created for monitoring the state of the prewrite area, and data in the prewrite area is conditionally invalidated based upon the information contained in the scoreboard memory structure. By conditionally invalidating the prewrite data, the write performance of the RAID storage system is improved.

Abstract: A system, method and computer program product comprising a storage manager independent configuration interface translator which requests an opaque listing of the available storage devices from an associated metadisk driver and determines a subset of the listing meeting a preselected search criteria. The resultant opaque listing is then converted to a non-opaque format listing for presentation to a user of the computer system in a desired format such as through a command line or graphical user interface. A notification mechanism is also provided that presents information about storage devices which have in some way changed while in use.

Abstract: In a computing system having a plurality of storage devices, notification of an application program of a change of state in a storage device so that corrective action can be taken. A notification module creates and maintains an event queue for storing events corresponding to changes in the state of the storage devices. The notification module indicates to the application programs that events are in the queue. The queue conditions are monitored by the notification for queue maintenance.

Abstract: A metadisk driver functionally intermediate a computer operating system and one or more metadrivers and underlying layered drivers provides a driver rename/exchange function which does not depend on any particular driver having knowledge of the private data structures of any of the other drivers. The rename/exchange technique implemented thereby may be conducted while the underlying devices are on-line and comprise atomic operations which are, therefore, recoverable inasmuch as the operation will have either been completed or will not be committed in the event of any interruption.

Abstract: In a computing system utilizing redundant storage devices arranged in the RAID disk array, data is stored in the computing system using a memory cache created from system memory and the disk array. A checkpoint module detects a fault in the computing system and generates a fault indication, and a cache manager writes data and parity to the memory cache in a first mode, and writes data and parity to the storage device in a second mode. In response to the fault indication, the checkpoint module copies the data contained in the cache to the disk array, and switches the cache manager from the first mode to the second mode.

Abstract: An improvement relating to the security of an operating system for either a stand alone computer system or for a networked computer system. The operating system provides improved security for programs available on the computer system having different security protocols. The operating system unifies these security protocols for each user based on unique user credentials. The system operates, upon request to start a program procedure by the user, to authenticate the identity of the user based on information unique to that user. Following which, the system generates a user handle associated with the user. The system then notifies each of the security protocols of the user handle associated with the user. The system then generates new user credentials for each of the security protocols. These user credentials are associated with the user handle and then the user handle is mapped to the unique user's credentials for each program procedure.
