Abstract: Embodiments described herein provide a method for an error logging mechanism operated with controller area network (CAN) buses within an Ethernet network. A first interrupt request indicative of a first error condition that occurs at the first CAN bus is received at an Ethernet bridge and from a first CAN controller connected to a first CAN bus. In response to the first interrupt request, the first interrupt request is serviced by retrieving, from a first error register at the first CAN controller, information relating to the first error condition. The information relating to the first error condition is encapsulated in a first frame in compliance with a layer 2 transport protocol for time-sensitive applications. The encapsulated first frame is then sent, via an Ethernet switch, to an error logging device installed at a location remote to the first CAN bus.

Abstract: In one embodiment, the present disclosure pertains to testing. In one embodiment, software tests are performed on a first software server. Tests may be repeated a plurality of times to check for consistent failures or passes. Test results are sent to a second software server. The test results are stored in one or more databases on the second software server, where particular test results are associated with one or more fields specifying whether the test was passed and whether the test was failed. Tests that were both passed and failed may be deemed “flaky” tests. The second software server may generate a query to retrieve test results from the database that both passed and failed at least one test (flaky tests). Flaky tests may be quickly retrieved and processed.

Abstract: Example redundant array of independent disks (RAID) storage systems and methods provide rebuild of logical data groups in priority order. Storage devices are configured as a storage array for storing logical data groups distributed among the storage devices. The logical data groups are written in a configuration of RAID stripes in the storage devices. A logical group index includes a logical group map for each logical data group and identifies corresponding logical blocks. When a storage device fails, the rebuild queue is ordered based on the priority of the logical data groups and rebuild to the replacement storage device is completed in the priority order.

Abstract: A processing device receives a request to recreate an application from a particular point in time. The processing device determines a set of hierarchical tags in a data store of hierarchical tags, the set of hierarchical tags describes a computing environment hosting the application from the particular point in time. The processing device copies, from the data store, a snapshot associated with a source data tag of the set of hierarchical tags. The processing device recreates the computing environment hosting the application from the particular point in time in a replication environment using the set of hierarchical tags and the snapshot.

Abstract: A storage system periodically replicates data to another storage system for data backup and protection. The storage system is configured to detect an irregularity potentially causing a fault in the storage system. Such a detected irregularity may a component failure in a storage device, a temperature change in a storage device, etc. In response to the detected irregularity, the storage system increases a replication rate of data to the backup storage system.

Abstract: Systems and methods are disclosed for monitoring features of a computing device of a distributed computing system using a self-monitoring module. The self-monitoring module can include multiple feature-specific monitoring modules and one or more parent nodes for the feature-specific monitoring modules. A feature-specific monitoring module can identify or detect a fault status change, such as a fault condition or fault resolution, for one or more features. Based on the identified fault conditions or fault resolutions, the feature-specific monitoring module can determine an internal status and communicate an updated status to a parent node.

Abstract: Multi-port data storage device capabilities can be provided by a remote host connected to a diskgroup that has a first single port data storage device and a second single port data storage device. Initialization of a first logical volume and a second logical volume in each single port data storage device allows a data access request to be serviced from the remote host with the first logical volume of the first single port data storage device. Data virtualized from the first logical volume of the first single port data storage device to the second volume of the second single port data storage device allows accessing the second volume of the second single port data storage device in response to a request to a data request to the first volume of the first single port data storage device.

Each vector clock may include a clock value for each of the actor pairs.

Abstract: Embodiments for disaster recovery in a disaggregated computing system. A memory is allocated at a secondary, disaster recovery site for data received from a primary site. A degree of resiliency is defined for respective workloads associated with the data at the primary site to specify how critical each respective workload is to execute in case of disaster, and the data is replicated to the allocated memory at the disaster recovery site according to the degree of resiliency.

Abstract: Aspects of the disclosure relate to management node failover systems and methods. The system includes two management devices and a detection and reversal device. Each of the two management devices has a processor and a non-volatile memory storing computer executable code. The two management devices function respectively as an active node and a passive node. The detection and reversal device monitors status of the active node. When the active node fails, the detection and reversal device sends an activation signal to the passive node. The passive node, in response to receiving the active signal, switches from the passive node to the active node.

Abstract: Described herein are a method and apparatus for memory vulnerability prediction. A memory vulnerability predictor predicts the reliability of a memory region when it is first accessed, based on past program history. The memory vulnerability predictor uses a table to store reliability predictions and predicts reliability needs of a new memory region. A memory management module uses the reliability information to make decisions, (such as to guide memory placement policies in a heterogeneous memory system).

Abstract: A system and method that automatically detects anomalies in a cloud service system on an ongoing basis and which can be used to trigger live migration of cloud services includes a cloud server system configured to provide a plurality of virtualized cloud services through processes running over a set of virtual machines hosted on the cloud server system, and a processor which receives data related to the operations of the virtual machines and determines whether any of the virtual machines are exhibiting anomalous behavior. The processor applies a Kalman Filter to make predictions on the future state and covariance of the virtual machines and then calculates the log likelihood of the predicted values. If the predicted values deemed to be very unlikely, then the processor signals that an anomaly has occurred.

Abstract: Implementations of the present solution disclose a method for triggering view switching in a blockchain without requiring a separate consensus to be executed by the backup nodes. The blockchain primary node receives a trigger that indicates a view switching condition. Then the primary node selects a successor node, and initiates a view switch, where the successor node will act as a new primary node in the next view. The new primary node can then initiate a consensus in the next view.
