The present disclosure relates to a communication method for a slave device in a master-slave communication structure, including: sending a boot report to the master device at power-up to report that the slave device is booting, wherein the boot report includes identity information for the slave device; receiving a heartbeat message from the master device; and if no heartbeat message is received from the master device for more than a predetermined time, the boot report is continuously sent to the master device at predetermined intervals until a feedback message of successful connection is received from the master device. Further, the present disclosure relates to a communication method for a communication system having a master-slave communication structure, a communication device for a slave device in a master-slave communication structure, and a communication system having a master-slave communication structure.

A system for representing attributes in a transportation system digital twin includes a digital twin datastore and one or more processors. The digital twin datastore stores a transportation-system digital twin including real-world-element digital twins embedded therein. The transportation system digital twin corresponds to a transportation system. Each real-world-element digital twin provides a digital twin of a respective real-world element that is disposed within the transportation system. The real-world-element digital twins include mobile-element digital twins. Each mobile-element digital twin provides a digital twin of a respective mobile element within the real-world elements. The one or more processors are configured to, for each mobile element, determine, in response to an occurrence of a triggering condition, a position of the mobile element, and update, in response to determining the position of the mobile element, the mobile-element digital twin corresponding to the mobile element to reflect the position of the mobile element.

A data storage system includes a plurality of storage devices organized as a redundant array of inexpensive disks (RAID) storage array and a RAID controller. The RAID controller monitors the plurality of storage devices in the RAID storage array. The RAID controller also detects that a host read request of a host has a latency exceeding a latency threshold. Based on the monitoring, the RAID controller determines whether a proactive rebuild of a data requested by the host read request in absence of a data error would likely be beneficial to performance. Based on determining that a proactive rebuild of the data requested by the host read request would likely be beneficial to performance, the RAID controller initiates the proactive rebuild of the data and sends the requested data to the host.

A storage manager control application facilitates interactions with, and configurations of, a storage manager that manages one or more client computing devices of an information management system. The storage manager control application may be implemented using a variety of modules that allow a user to interact with the storage manager in various ways. Using the storage manager control application, a user may view a backup status of the information management system, and view the backup status of specific client computing devices that are managed by the storage manager. The user may also search for various entities and/or objects within the information management system using the storage manager control application. In addition, a user may view the status of one or more backup jobs configured within the information management system, as well as backup plans that have been established for one or more of the client computing devices.

A hardware system for simulating a network physical layer for communication channels. The hardware system includes a plurality of hardware processors configurable to model a network physical layer and communication channels. The hardware system further includes a multi-point data switch configured to be coupled to various data log points associated with the plurality of hardware processors. The hardware system further includes a RAM coupled to the multi-point data switch, where the RAM is configured to store log data provided by the multi-point data switch as software defined data structures

A memory management method is provided according to the invention. The method includes: reading a physical unit and updating a read count of the physical unit; scanning the physical unit if the updated read count is not less than a read count threshold; and adjusting the read count threshold according to the read count and a read error bit. Therefore, a data unit that needs to be scanned can be determined to reduce unnecessary data scanning.

A method, apparatus and system for providing process-level forensics for a plurality of application containers includes for each of the plurality of application containers; monitoring forensics information of the application container, encoding the monitored forensics information using an encoder of a predetermined encoder/decoder pair to determine a forensics model, decoding the forensics model to determine a reconstructed representation of the forensics information, comparing the reconstructed representation of the forensics information to the monitored forensics information to determine an error and comparing the error to a threshold to determine if an error above the threshold exists. If the error is below the threshold, the forensics model is communicated to a higher-level manager to be used for higher-level management. If the error is above the threshold, the monitored forensics information of the application container is also communicated to the higher-level manager. The predetermined encoder/decoder pair is determined using an autoencoding process.

A method is described that includes processing, by a memory subsystem, a read memory command that is addressed to a first die of a memory device. The memory subsystem determines whether processing the read memory command failed to correctly read user data from the first die and, in response to determining that processing the read memory command failed to correctly read user data from the first die, determines whether the first die has failed. In response to determining that the first die has failed, the memory subsystem performs an abbreviated error recovery procedure to successfully perform the read memory command instead of a full error recovery procedure.

A local management-based Power Over Ethernet (PoE) switch and a management system. The PoE switch includes a casing, a Liquid Crystal Display (LCD) screen, a monitoring Micro Control Unit (MCU) module, a power system module, a display module, a PoE system module, a switch system module, a key group arranged on the casing, and a key module. The key module transmits information to the MCU module through the display module, and the MCU module connected with the display module, the PoE system module, the switch system module and the key module respectively through a bus performs corresponding operation according to the information. By adoption of the technical solution, working states of the PoE and switch system modules are visually displayed on the screen, and then are correspondingly processed according to the information and displayed on the screen.

A storage device is provided which shares a host memory with a host. The storage device includes an interface that exchanges data with the host and implements a protocol to use a partial area of the host memory as a buffer of the storage device. A storage controller of the storage device monitors deterioration information of a first area of the buffer and transmits a corruption prediction notification associated with the first area to the host based on a result of the monitoring.
