Abstract: A method analyzes dependency information for a first data store. Upon determining that a data pipeline associates a first log type generated by the first data store with a second log type generated by a second data store, a first number of logs of the first log type that are generated at a first time, a first baseline number, and a first threshold value are determined. Upon determining that the first number of logs differs from the first baseline number by less than the first threshold value, a second number of logs of the second log type that are generated at a second time, a second baseline number, and a second threshold value are determined. Upon determining that the second number of logs differs from the second baseline number by more than the second threshold value, the data pipeline is identified as degraded.

Abstract: A network device may execute a master application shared with another network device via a session, and may receive, by a backup application replication kernel, a replicated data object. The backup application replication kernel may provide the replicated data object to a backup application, and may calculate a time delta between when the replicated data object is received and when the replicated data object is consumed by the backup application. The backup application replication kernel may determine whether the time delta exceeds a first threshold or a second threshold, and may generate a session flag based on the time delta exceeding the first threshold or the second threshold. The backup application replication kernel may provide the session flag to a master application replication kernel and to the backup application, and the master application replication kernel may provide details of the session to the master application and the backup application.

Abstract: According to an embodiment, a controller acquires a first temperature detection value and executes an acquisition operation on a first storage area. The controller converts a first voltage value into a second voltage value representing the read voltage in a temperature set value based on the first temperature detection value and records the second voltage value. The acquisition operation is an operation of determining, by using the read voltages, whether memory cells are ON or OFF and acquiring the first voltage value representing the read voltage for suppressing error bits. After that, the controller acquires a second temperature detection value and converts the second voltage value into a third voltage value representing the read voltage in the second temperature detection value. The controller reads data from the memory cells by using, as the read voltage, a voltage indicated by the third voltage value.

Abstract: Disclosed in some examples, are methods, systems, and machine-readable mediums in which application state is saved using in-memory versioning in a shared memory pool of disaggregated memory. By utilizing a disaggregated memory pool, the processing resources may be on separate devices than the memory those resources are using. As a result of this architecture, a failure of hardware of processing resources or an application does not necessarily also cause the hardware resources of the memory devices to fail. This allows a standby application executing on standby processing resources to quickly resume execution when a primary application fails by utilizing the memory pool assigned to the primary application in the memory pool.

Abstract: Methods and systems for managing operation of a deployment comprising data processing systems are disclosed. The operation of the deployment may be managed by reducing a likelihood of failure of services to a data processing system. The likelihood of the failure of the services may be reduced by assigning a pod to a data processing system based on identifying fault zones and implementing a fault zone policy. The fault zones may be identified by determining data processing systems that are managed by an infrastructure component. The fault zone policy may be implemented by limiting the assignment of the pod to any number of data processing systems within a fault zone.

Abstract: A scale-out computing cluster may include a large number of computing servers and storage devices. In order to provide high reliability, the computing cluster must be able to handle failures of individual devices. Reliability of the computing cluster may be improved by providing a standby server for each active server in the computing cluster. If any active server fails, the corresponding standby server is activated. The failed server may be brought back online or replaced, at which time the restored server becomes the standby server for the now-active original standby server. During the restoration period, if any other active server fails, the standby server for that active server is immediately activated. As a result, the recovery ability of the computing cluster is only challenged if both servers of an active/standby pair fail during the restoration period, substantially improving reliability.

Abstract: Aspects of the disclosure provides various systems, apparatuses, and techniques for reducing latencies and power consumption of link training or retraining. In some aspects, the techniques use a specific register to identify the cause of link retraining. Based on the identified reasons of link retraining, the apparatus can selectively skip the initialization of certain redundant lanes of the link. In some aspects, the Universal Chiplet Interconnect Express (UCIe) Link Training and Status State Machine (LTSSM) can be configured to identify whether link retraining is initiated as part of a trainerror or linkerror exit or not. A UCIe device can have a redundant_recovery (RR) register that can be set to different values to identify the cause of link retraining (e.g., due to trainerror/linkerror or not).

Abstract: Aspects of the present disclosure provide a monitoring algorithm that ensures that each step of an automated virtual machine reclamation process executes correctly before moving on to the next step. After each step of the process, some implementations can determine whether the resulting data is correct. If the resulting data is incorrect, some implementations can initially revert any fields updated by the process to their correct value. Some implementations can further decide whether to resubmit the virtual machine for reclamation automatically, or queue it for manual review based on, for example, multiple or repeated failures, server or data center failures, etc. Thus, some implementations can not only automate each step of the reclamation process, but also provide process evaluation and error detection for the reclamation process.
