A first recovery instruction is sent to a second memory subsystem of the plurality of memory subsystems. The first recovery instruction directs the second memory subsystem to recover a first subset of data stored by the first memory subsystem. A second recovery instruction is sent to a third memory subsystem of the plurality of memory subsystems. The second recovery instruction directs the third memory subsystem to rebuild a second subset of data stored by the first memory subsystem. The first and second subsets of data differ from one another.

Abstract: Prioritization of VT scans can be performed using particular select gates of a memory device or memory sub-system in the absence of performing such select gate scan operations on all of the select gates of an entire memory die or of all the memory dice of a memory device or memory sub-system. A method for such prioritization of VT scans includes determining quality characteristics of a memory die and altering a threshold voltage applied to the memory die in performance of a select gate scan operation based, at least in part, on the determined quality characteristics of the memory die. Such methods can further include performing the select gate scan operation by applying signaling having the altered threshold voltage to a select gate of the memory die.

Abstract: Systems for distributed data storage. A method commences upon accessing a set of data items that describe computing nodes to be organized into a ring topology. The ring topology and distributed data storage policies are characterized by quantitative failure-resilient characteristics such as a replication factor. Various characteristics of the topology serve to bound two or more availability domains of the ring into which the computing nodes can be mapped. A set of quantitative values pertaining to respective quantitative failure-resilient characteristics are used for enumerating candidate ring topologies where the computing nodes are mapped into the availability domains. Using the quantitative failure-resilient characteristics, alternative candidate ring topologies are evaluated so as to determine a configuration score for candidate ring topologies. A candidate ring topology is configured based on a computed configuration score surpassing a threshold score.

Abstract: Embodiments of the invention relate to methods and systems for efficiently backing up a production host. In one or more embodiments, assets are assigned to one or more slices. Depending on the type of assets assigned to a slice such as directory information versus data, the slices are assigned a flag. This flag may then be used to determine which streams a slice should be assigned to and based on the specific flags of the slices assigned to each stream, the order by which the streams are transferred to backup containers located in a backup storage may be determined. This may result in better or more efficient utilization of available connections between the containers and the production host, resulting in better utilization of system and network resources as well as a better backup and recovery performance.

Abstract: The technology described herein is directed towards automating the replacement of a virtual machine when the hardware underlying the virtual machine fails, including in a cloud computing environment in which nodes in a cluster map to virtual machines being deployed within that cloud provider. An automated workflow to perform cluster self-healing is started upon detection of an unrecoverable instance failure of a virtual machine, e.g., because of underlying hardware failure. The failed virtual machine is terminated, and a new, replacement virtual machine that matches characteristics of the failed virtual machine is created to join the cluster. Data of the failed node is re-protected, such as by restoring data maintained with a protection scheme to remaining virtual machines of the cluster. When the data is re-protected and the replacement virtual machine has joined the cluster, the data is rebalanced across the cluster nodes, including to the new virtual machine.

Abstract: A system performs group testing on a population of items. The group testing identifies items satisfying particular criteria from a population of items, for example, defective items from the population. The group testing may be performed for software or hardware testing, for testing a human population, for training of deep learning applications, and so on. The system trains a machine learning based model, for example, a reinforcement learning based model to evaluate groups. The model may further determine system dynamics that may represent priors of items. An agent treats the population and groups of items being tested as the environment and performs actions, for example, adjusting the groups. The system also performs a non-adaptive strategy based on monte carlo simulation of tests based on a simulation results.

Rebuilding the information from the first storage device in the parity space of the second storage device may include copying the information from the first storage device to the parity space of the second storage device. The method may further include copying the rebuilt information from the parity space of the second storage device to a replacement storage device.

Abstract: Systems and methods for detecting hardware faults in computer-based feedback control systems. Multiple instances of the system control program(s) are run on system processors. System sensor data are input to each instance, and the control commands output by each instance are compared. As instantiations of the same programs receive largely the same sensor data, differences between output commands may indicate the presence of one or more hardware faults.

Abstract: A feedback mechanism that reports software issues between users of software applications and the developers of the software applications. The feedback mechanism generates feedback logs that capture moments of user frustration at the moment a user encounters issues with using a particular software application executing on a client device. The feedback mechanism is triggered to generate a feedback log by the user via a predetermined set of user inputs. Once generated, the feedback log captures an associated importance level, a user description, and/or context information (such as application and command activity information) for the particular software application and one or more other software applications that interacted with the particular software application executing on the client device. The feedback log can also capture multimedia content such as audio, images, and videos. The feedback log is then transmitted to a server of a developer of the particular software application.

Abstract: A computerized method is disclosed for automated handling of data ingestion anomalies. The method features training a data model based on a first volume of data associated with a first time period.

After, a correlative analysis between the predicted data ingestion volume and an actual data ingestion volume during the second time period is conducted to produce a prediction error. A notification is generated based on the prediction error.
