Abstract: A control method comprising: a first step of detecting, by the server module, a failure in the first interface; a second step of executing, by the server module, given recovery processing when a failure is detected in the first interface; a third step of using, by the coupling module, the first end point to detect a failure in the first interface and output a failure notification; a fourth step of converting, by the coupling module, the failure notification into a notification of disconnection of the first interface, and transmitting the disconnection notification generated by the conversion to the storage module from the second end point; and a fifth step of disengaging, by the storage module, coupling to the server module when the disconnection notification is received from the coupling module.

Abstract: For efficient handing of semi-asynchronous RAID write failures using a processor device in a computing environment, a write operation is committed on a primary copy of data on a primary entity while sending the data to a secondary entity while awaiting an acknowledgment by the secondary entity. The acknowledgment indicates to the primary entity that metadata for the write operation has arrived at the secondary entity without necessarily indicating the data has arrived at the secondary entity. The acknowledgment is sent from the secondary entity regardless of a write failure and allowing the secondary entity to perform a recovery operation if a write failure occurs.

Abstract: A method begins by a dispersed storage (DS) processing module receiving a set of encoded data slices, where some of the encoded data slices have an integrity issue such that less than a decode threshold number of encoded data slices have valid integrity. The method continues with the DS processing module creating partial coded matrices from the set of encoded data slices and generating partial decoding matrices. The method continues with the DS processing module generating a test data matrix based on the partial coded matrices and the partial decoding matrices, encoding the test data matrix into a set of test encoded data slices, and generating integrity information for the set of test encoded data slices. When the integrity information is valid, the method continues with the DS processing module utilizing the test data matrix as a data matrix and converting the data matrix into a recovered data segment.

Abstract: A method associates errors by causal relationship in software systems where multiple threads share access to hardware and/or software components. Where a software object, such as a lock, is provided, a thread can place an error ID into the object if encountered while the first thread controls the object. A second thread can retrieve the error ID and associate it as a parent error for any time-out error encountered while waiting for the software object. Errors can be reported and displayed in a causal graph for determining root causes. Errors can have a severity that can facilitate the display of errors to a user. Root cause errors can be assigned the severity of the most severe of its child errors to assist a user in determining a root cause. Errors can further be displayed or masked based on the severity assigned to the errors and/or their parent or child errors.

Abstract: Artifact selection by obtaining textual reports indicating potential defects in a program product. The textual reports are associated with artifacts of the program product. The textual reports and artifacts are automatically analyzed to estimate severity of potential errors in the artifacts of the program product, by utilizing a statistical model to estimate the severity based on content of the textual reports. The statistical model is trained with respect to a training dataset. A subset of the artifacts is determined based on the estimated severity.

Abstract: A system for delivering content over a network includes a server. The server is configured to divide the content into multiple segments, to create multiple data streams using the segments of the content, and to transmit each of the data streams via a respective multicast session, wherein a copy of each of the multiple segments is transmitted during a single time slot of the multicast session.

Abstract: A memory module includes a memory module copy engine for copying data from an active memory die to a spare memory die. Access is mapped away from the active memory die to the spare memory die.

Abstract: A computer-implemented method for preventing failures of nodes in clusters may include (1) identifying a node that is part of a cluster of nodes and that communicates, via a heartbeat sent at a regular interval to the cluster, that the node is functional and connected to the cluster, (2) calculating a current workload for the node based on a utilization of computing resources on the node, (3) determining, based on the current workload, that the node is functional and connected but is in an excessive load condition and a failure to send the heartbeat within the regular interval is due to the excessive load condition, and (4) setting a new interval for the heartbeat of the node that is longer than the regular interval in response to determining that the node cannot send the heartbeat at the regular interval. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A mechanism for providing non-volatile memory for suspend-to-RAM in a computer system. A method includes searching for a checkpoint message in a memory upon receipt of notification of restoring of power in a system. The checkpoint message is a confirmation of storing of state of a storage device prior to loss of the power in the system. The method also includes determining whether the checkpoint message indicates that the system reached the power integrity checkpoint. The power integrity checkpoint is a confirmation of the storing of the state of other device prior to the loss of the power in the system. The other device is different from the storage device. The method further includes restoring operating conditions of the system when it is determined that the system has reached the power integrity checkpoint.

Abstract: Systems and methods are provided herein that can facilitate the managed reliability of data storage, including management of device remanufacturing and masking from an operating system a failure or predicted failure of a device running on a computer or a networked cluster of computers having access to the device. The systems and methods may facilitate removal of a device by coordinating among computers or controllers in a network cluster the logical removal of a device. At a later time, a coordinated logical re-introduction of the device to the systems or computers from which the device was logically removed can be performed. This can be accomplished via a virtualization system that may include a device function driver (DFD), a device virtualization bus driver (DVBD), and a device management service (DMS).

Abstract: Large amounts of unstructured log data generated by software and infrastructure components of a computing system are processed and analyzed in real time to identify anomalies and potential problems within the computing system. A log analytics module reduces both the volume and level of detail of log data by first classifying log messages into message types based on their content similarity. The log analytics module may then further reduce data by grouping bursts of log messages into log events. Patterns within these log events, such as the collection and number of different message types that comprise the event, can be used to identify anomalous events.

Abstract: A method that prevents unnecessary data recovery includes receiving, at a data processing device, a status of a resource of a distributed system. When the status of the resource indicates a resource failure, the method includes executing instructions on the data processing device to determine whether the resource failure is correlated to any other resource failures within the distributed system. When the resource failure is correlated to other resource failures within the distributed system, the method includes delaying execution on the data processing device of a remedial action associated with the resource. However, when the resource failure is uncorrelated to other resource failures within the distributed system, the method includes initiating execution on the data processing device of the remedial action associated with the resource.
