Aspects of the present invention relate to a method, a control system, a vehicle, a system, and a non-transitory computer readable medium. Application program code is downloaded to the control system via an interface and installed on the control system. Then, it is determined whether the control system is able to communicate with an external device via the interface while running the installed application program code, and the installed application program code is subsequently loaded on startup of the control system in dependence on a determination that the control system was able to communicate with the external device.

Example implementations relate to preserving data availability in a constrained deployment of an HA system (e.g., an HA storage system) in the presence of pending faults. According to an example, a first arbiter, acting as a witness to facilitate maintaining quorum for the HA system, and a first node are provided within a first failure domain; and a second arbiter, serving as a backup arbiter, and a second node are provided within a second failure domain. Responsive to receipt of an indication of a pending fault impacting the first failure domain by a member of the current configuration of the HA system, establishment of a new configuration, excluding the first arbiter and including the second arbiter, is initiated. Responsive to a majority of the current configuration installing the new configuration, the second arbiter is enabled to serve as the active arbiter by transferring state information to the second arbiter.

A battery controller used in an electronic device supplied with electric power from a battery pack including a rechargeable battery includes a battery monitor for monitoring remaining battery charge in the rechargeable battery, and a power supply controller. The battery monitor issues an alarm when the remaining battery charge lowers to a threshold or below, and, after that, shuts down upon receiving a shut-down command from the power supply controller. The power supply controller sends the shut-down command to the battery monitor upon receiving the alarm from the battery monitor and determining that the remaining battery charge is equal to or below the threshold.

Analytics-based optimized maintenance operations for a hyper-converged infrastructure are described. An example includes instructions to establish an order for a sequence of maintenance operations including collecting data points that relate to high availability of multiple nodes in a storage infrastructure; performing analysis of the collected data, including discovery of groups of nodes that don't have mutual relations with other paired nodes; receiving a request to perform a maintenance operation for the plurality of nodes; generating an ordered sequence of groups of nodes for the maintenance operation based at least in part on the analysis of the collected data, each group including one or more nodes; and performing the maintenance operation for the plurality of nodes according to the sequence of groups of nodes, wherein the maintenance operation includes a power cycle for each of the plurality of nodes.

A method for performing stutter of dynamic random access memory (DRAM) where a system on a chip (SOC) initiates bursts of requests to the DRAM to fill buffers to allow the DRAM to self-refresh is disclosed. The method includes issuing, by a system management unit (SMU), a ForceZQCal command to the memory controller to initiate the stutter procedure in response to receiving a timeout request, such as an SMU ZQCal timeout request, periodically issuing a power platform threshold (PPT) request, by the SMU, to the memory controller, and sending a ForceZQCal command prior to a PPT request to ensure re-training occurs after ZQ Calibration. The ForceZQCal command issued prior to PPT request may reduce the latency of the stutter. The method may further include issuing a ForceZQCal command prior to each periodic re-training.

Systems and methods are disclosed herein for monitoring, detecting, and mitigating hardware and software failures. An error detection module monitors the execution of software processes and detects failures of the monitored processes. The error detection module may monitor reboot events and correlate reboot events with failures of the monitored software processes. If a monitored process fails, the error detection module may log the failure and its cause. If the same process has failed numerous times, causing the user device to experience a reboot loop, remedial action may be taken based on the cause of the failure.

An electronic apparatus and a power controlling method thereof are provided. The electronic apparatus may include a wireless communicator that communicates with a remote controller, a wired communicator that connects with an external input device and a processor that controls the wireless communicator to transmit a control signal to the remote controller for turning off power of the connected external input device in response to receiving a signal from the remote controller for turning off power of the electronic apparatus.

A system and method executed by a computer server include determination that the computer server has lost network connectivity and, in response to the determination that the computer server has lost network connectivity, disabling of power to a volatile memory of the computer server. Determining that the computer server has lost network connectivity may include transmission of data to an external system and determination that a response to the data was not received from the external system. Disabling of power to the volatile memory may include transmission of a request to an operating system of the system to initiate a power-down sequence of the system.

A system for shutting down a process of a database is provided. In some aspects, the system performs operations including tracking, during startup of a process, code locations of a process in the at least one memory. The operations may further include tracking, during runtime of the process and in response to the tracking the code locations, memory segments of the at least one memory allocated to the process. The operations may further include receiving an indication for a shutdown of a process. The operations may further include waking, in response to the indication, at least one processing thread of a plurality of processing threads allocated to a database system. The operations may further include allocating a list of memory mappings to the plurality of processing threads. The operations may further include freeing, by the first processing thread, the physical memory assigned to the processing thread by the memory mappings.
