Abstract: Various embodiments provide handling block program failure in a memory sub-system that supports zones. In particular, some embodiments described herein handle block program failure during a data write (e.g., host data write) to a cache block of a zone on a memory device on a memory sub-system, block program failure during refresh of a cache block of a zone on a memory device on a memory sub-system, block program failure during migration of data between a cache block and a non-cache block of a zone on a memory device on a memory sub-system, block program failure during refresh of a non-cache block of a zone on a memory device on a memory sub-system, or some combination thereof.

Abstract: A system detects a switch off event sent by a virtual machine management server, and identifies a virtual machine that is tagged by the switch off event and protected by a data protection server, and applies a deletion lock to the virtual machine. The system detects a deletion event sent by the virtual machine management server, and identifies a virtual machine that is tagged by the switch off event, protected by the data protection server, and tagged by the deletion event. The system creates a backup file for the virtual machine that is tagged by the deletion event. The system releases the deletion lock from protecting the virtual machine that is tagged by the deletion event. If the deletion event was accidental or malicious, the system uses the backup file to restore the virtual machine which was deleted by the deletion event after the release of the deletion lock.

Abstract: A backup process implemented by generating data to be backed up from a file-based application or an object-based application from a respective application host. A generic proxy component collocated with the application host is deployed and contains protocol specific servers and a DDBoost client. The data is transmitted from the application host to the generic proxy using a defined file transfer protocol. The data is then transformed in a protocol specific server of the generic proxy to a format compatible with the DDBoost client, and to leverage distributed segment processing (DSP) to optimize data transfers using the generic proxy. The transformed data is then transmitted to a backup system over a network using a data transmission protocol and the data stored by the backup system in a data storage target.

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: A method comprises establishing a communications channel between a host device operating system and a chassis management module of a chassis, analyzing, by the chassis management module, operational data corresponding to one or more chassis components and data corresponding to usage of one or more nodes by the host device operating system, and activating one or more of a plurality of flags based at least in part on the analyzing, wherein the plurality of flags respectively correspond to different failure events associated with at least one of the one or more chassis components and the one or more nodes. The one or more flags are sent from the chassis management module to the host device operating system via the communications channel.

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.

Abstract: A safety mechanism circuit is provided. The safety mechanism circuit is disposed on a motherboard which includes a connector to be connected to a function circuit. In response to the function circuit being coupled to the connector, a detection circuit detects the voltage level of a contact terminal. In response to the voltage level of the contact terminal not being equal to a predetermined level, an operating circuit enters a safety mode to perform a safety operation. In response to the voltage level of the contact terminal being equal to the predetermined level, the operating circuit enters a normal mode to stop performing the safety operation.

Abstract: This disclosure is directed to a system for performing read error handling. The system reads a first portion of a memory block from a memory device and skips reading a second portion of the memory block when determining that a read bit error rate (RBER) associated with the second portion of the memory block transgresses an RBER threshold. The system, before initiating error correction operations on the second portion, continues to read additional portions of the memory block after determining that the RBER associated with the second portion of the memory block transgresses the RBER threshold and performs the error correction operations on the second portion using at least the first portion of the memory block and the additional portions of the memory block to correct the second portion of the memory block.

Abstract: Enhancing data replication performance optimization by maintaining parent-child file relationships when cloning an entire or portion of a first namespace to a second namespace for backups cloned across namespaces in a deduplication filesystem. The file copies may be made by either virtual synthetic (VS) copies that keep a one-way relationship between parent-child files or fast copy overwrite (FCOW) copies that keep a two-way parent-child relationship. Extended attributes are used as metadata for the files to indicate a path or recipe to generate the child file. The extended attributes for the cloned parent and child files are fixed to reference the second namespace so that a relative relationship between the parent and child files is maintained after cloning to the second namespace.

The routing processor is coupled to the fault tolerant engine, and the routing processor is provided in the leaf switch.

Abstract: Methods, systems, and apparatus, including computer-readable storage media for handling component error of datacenter infrastructure by training machine learning models to handle errors when the models are deployed. Rather than predict or mitigate errors in the hardware of a datacenter or another site deploying the machine learning model, the model is trained to perform a task with comparable accuracy and efficiency even when some hardware on which the model is deployed fails. Component error can instead be simulated during training to cause the machine learning model deployed on the infrastructure to learn to correct errors caused by the component errors. The model can continue to be trained to compensate for periods in which not all parts of the model are available at inference. Updates to the model can be backpropagated to correct errors for handling instances of component error.
