A data operation error for a data operation initiated in a first non-volatile memory die of a plurality of non-volatile memory die in the data storage system is detected. An error count for an error type of the data operation error for the first non-volatile memory die is incremented. The incremented error count satisfies a first threshold value for the error type of the data operation error is determined. The first non-volatile memory die is marked for exclusion from subsequent data operations.

Abstract: Systems and methods for are provided for predicting impending failure of a database and preemptively initiating mitigating failover actions, for example by shedding connections or redirecting connection requests to an alternate database that can fulfill resources being requested. In an example embodiment, to detect a slow or unstable database, connection wait times are monitored over a rolling window of time intervals, a quantity of intervals in which at least one excessive wait time event occurred are counted during the time window, and if the quantity exceeds a threshold, the database is deemed unavailable, thereby triggering connection adjustments.

Abstract: Techniques that facilitate re-hosting a subset of a serverless application are provided. In one example, a system includes an interface component, a rewriter component and a broker component. The interface component receives identifier data from a computing device that identifies a portion of a serverless application to be re-hosted by the computing device. The computing device is in communication with the serverless computing system via a network device. The rewriter component rewrites the serverless application to allow the first portion of the serverless application to be executed by the computing device and another portion of the serverless application to be executed by the serverless computing system. The interface component re-routes the first portion of the serverless application to the computing device to facilitate a debugging session for the first portion of the serverless application that is performed by the computing device.

Abstract: Systems and methods are described for improved error logging during system boot and shutdown. A hardware initialization firmware on a computing device can include a logging module. When errors occur during early system booting or late system shutdown, the firmware can create error logs. The logging module can receive the error logs and prioritize them according to a set of rules. The logging module can select error logs of the highest priority up to a predetermined maximum amount. The logging module can modify the error logs using a shorthand form and write them to nonvolatile random-access memory. The firmware can initialize runtime services and launch an operating system. A system logger on the operating system can retrieve the error logs, save them to a file, and erase them from the memory.

Abstract: A management entity receives device fingerprints representing corresponding devices connected to one or more networks. Each device fingerprint includes a multi-bit word indicating hardware, software, network configuration, and failure features for a corresponding one of the devices. The management entity processes the device fingerprints using different methods including statistical risk of failure scoring methods and machine learning risk of failure scoring methods, to produce from each of the methods a respective risk of failure for each device. The management entity combines the respective risk of failures for each device into a composite risk of failure for each device, ranks the devices based on the composite risk of failures for the devices, to produce a risk ranking of the devices, and outputs the risk ranking.

Abstract: The present disclosure generally relates to a method and device for reduce the amount of energy used to revert data within a storage device to a consistent state after a power loss event. Once power is lost from a host device, and prior to complete shutdown, a log is created within non-volatile memory (NVM) of the storage device. The log contains logical block addresses (LBAs) corresponding to data that experienced a write failure. At the next power-on event, the log is checked to see if any LBAs are present. If LBAs are present in the log, then the data that experienced a write failure can be properly written to the storage device.

A determination can be made as to any remedial operations that can be performed to mitigate errors of significance.

Abstract: Techniques for performing remote diagnostics in computing systems are disclosed herein. In one implementation, a first computing device can transmit to a remote server, data reporting an operational issue related to a second computing device. The remote server can then transmit a diagnostic command to the second computing device via the computer network. The second computing device can then execute the diagnostic command to generate diagnostic information. Upon receiving the generated diagnostic information from the second computing device, the remote server can combine the data from the first computing device reporting the operational issue with the generated diagnostic information from the second computing device and store the combined data as a database record corresponding to the reported operational issue.

Abstract: Techniques for predictive system remediation are disclosed. Based on attributes associated with applications of one or more system-selected remedial actions to one or more problematic system behaviors in a system (e.g., a database system), the system determines a predicted effectiveness of one or more future applications of a remedial action to a particular problematic system behavior, as of one or more future times. The system determines that the predicted effectiveness of the one or more future applications of the remedial action is positive but does not satisfy a performance criterion. Responsive to determining that the predicted effectiveness is positive but does not satisfy the performance criterion, the system generates a notification corresponding to the predicted effectiveness not satisfying the performance criterion.
